Ken Powell
Arthur F. Thurnau Professor and DEI Faculty Liaison
Aerospace Engineering, UM

The other talks this semester will be based on research in Aerospace Sciences and Engineering. This talk is based on research in the Social Sciences - particularly Psychology, Sociology, Economics - and how it applies to education and careers in aerospace engineering.

For the past five years, I have been part of a group of Michigan professors who read this social science literature, and meet to discuss its implications on academic careers - teaching, research, service and hiring of faculty. We also give talks about why and how to improve diversity in faculty hiring to faculty throughout the university, department chairs and deans, and faculty at other universities.

In this talk, I will present some classical and recent social science research about issues that affect our ability to hire and retain a diverse and excellent faculty, particularly in STEM fields, and especially in aerospace engineering. Topics will include implicit bias, stereotype threat, accumulation of disadvantage, and some of the steps we are taking as a university to improve the composition of the faculty. I will also present data about the demographics of the aerospace field, and give you some strategies for being a part of the much-needed solution to Aerospace's diversity challenges.

AE Dissertation Defense: "Development and Application of a Comprehensive Simulation for Modeling Helicopter Ship Landing" (September 6, 2019 1:30pm) https://events.umich.edu/event/65898 65898-16670220@events.umich.edu Event Begins: Friday, September 6, 2019 1:30pm
Location: Francois-Xavier Bagnoud Building
Organized By: Aerospace Engineering

A comprehensive simulation framework for modeling helicopter ship landing was developed. The framework includes high-fidelity models for: 1) vehicle flight dynamics, 2) Wind Over Deck (WOD), 3) ground effect, 4) ship deck motion, and 5) a robust flight control system.

Approach simulations were performed to assess the influence of WOD and ground effect on the UH-60A helicopter response. The WOD velocities were obtained from Detached Eddy Simulation of flow over a SFS2 ship. A gain scheduled LQR controller was used to track the approach trajectory. The WOD resulted in high frequency oscillations in the CG position coordinates and attitude angles. Oblique WOD conditions required greater control effort than the headwind case. Ground effect, modeled using a simple scaling factor, caused an 11.3% decrease in rotor power consumption.

A finite-state ground effect model was subsequently implemented to study the influence of inclined and moving decks. Hover and landing simulations were performed with a deck inclined at constant roll and pitch angles, and a deck undergoing isolated sinusoidal motion. Static deck roll produced an increase in the lateral inflow coefficient and the longitudinal cyclic input to the main rotor. Power requirements were significantly affected by heaving deck motion, highlighting the importance of modeling dynamic ground effect.

AE285 Undergraduate Seminar: Stealth…An Airplane Design Challenge (September 13, 2019 1:30pm) https://events.umich.edu/event/64895 64895-16485189@events.umich.edu Event Begins: Friday, September 13, 2019 1:30pm

In any combat scenario it is advantageous to be invisible or nearly invisible to your adversary (recall Desert Storm/bombing of Baghdad in 1991). In any situation it is very important to limit your opponent’s ability to harm you. More than 50 years ago initial stealth efforts focused on incorporating materials into an airplane’s design to reduce radar signatures. This proved to be a difficult and elusive goal. Today ‘stealth’ is designed into virtually every military vehicle.

This seminar will review the history of early stealth efforts and conclude with where the state-of-the-art is today. Air vehicles will be the main focus but it will also become clear that stealth is being added to the designs of land and sea vehicles as well. In this discussion reducing the ‘signature’ of an air vehicle to radar will be the primary focus. However, it should be recognized that IR (infrared), audible, and visual signatures can also be very important. They will be introduced with little discussion.

Ultimately, the goal is to have a vehicle survive and be able to fly tomorrow’s missions or successfully penetrate enemy positions to destroy its target. Stealth is a major component of survivability but it is not the only one.

What was the first stealth airplane? You may be surprised to learn the answer.

AE Chair's Distinguished Seminar Series: "Will Those Multi-rotor Aircraft Really 'Take-Off'?" (September 19, 2019 4:00pm) https://events.umich.edu/event/65225 65225-16555458@events.umich.edu Event Begins: Thursday, September 19, 2019 4:00pm

A number of hot topics in aviation right now — such as small UAS, urban air mobility, eVTOL aircraft — depend on new multirotor aircraft configurations. We know that these vehicles can fly in idealized conditions, but will it take for their use to really “take-off” in society? This presentation will start by reviewing the enablers of these new vehicles. Then, we’ll note a number of pressing issues being examined at Penn State that may limit their wide-spread use. For example, small rotors can easily accrete ice in less-than-perfect atmospheric conditions. When designed for maximum performance, they can be too noisy to operate in an urban environment — requiring trade-offs between vehicle performance and societal acceptance, and meriting a careful engineering design of their landing and take-off procedures.

These vehicles typically depend on new methods of flight control and the business cases for many of them assume highly automated operations allowing for reduced human staffing levels. In a broader sense, these vehicles, and their operations, are so novel compared to traditional methods for certification and operational approval that the aviation community needs to envision new bases for safety cases, including new concepts for human-autonomy teaming, new requirements for adaptive, contextualized behavior, and new methods for modeling and assessing safety.

This presentation discusses continuum deformation modeling of coordination of a large number of aerial vehicles treated as particles of deformable bodies (or continuum). Assuming desired coordination of an unmanned aerial system (UAS) team is the solution of Laplace equation, Lagrangian and Eulerian continuum mechanics will be applied to safely plan UAS coordination in a finite airspace. The Lagrangian continuum mechanics is used to manage large-scale coordination of a UAS team in a cluttered environment when the total number of agents is fixed. In this context, we optimize a large-scale continuum deformation coordination, and formally specify and verify collision-free collective motion with minimal communication and computation overhead, enabling distance between individual UAVs to significantly change while assuring the vehicles do not collide. Furthermore, the Eulerian continuum mechanics can be applied to achieve freely scalable coordination and manage traffic coordination in a finite airspace. Using the Eulerian description of continuum mechanics, the space and time allocated to an individual UAS can be effectively managed and the airspace capacity can be maximized through controlling UAS inflow and outflow at the airspace boundaries with minimum computation overhead. In particular, the airspace can be classified into planned and unplanned spaces by dynamically updating planned-unplanned airspace boundaries while nominal coordination is obtained as the solution of a governing PDE with spatiotemporal cyber-physical parameters. The unifying nature of Laplace equation and its application to Aerospace control problems will also be highlighted.

Mike Stengel
Senior Associate, AeroDynamic Advisory

The commercial aerospace industry today is part of the backbone of the global economy due to the number of programs in production and under development, as well as record high production rates. However, aircraft programs are expensive and risky, sometimes putting the entire company on the line. While the financial consequences can be high for a program that does not sell well, there are also “home runs” that have provided streams of profits for OEMs. In this seminar, Mike Stengel of AeroDynamic Advisory will examine some of the key aircraft platforms that have defined the Airbus & Boeing portfolios, including the challenges faced during the development, successes & failures in marketing the aircraft to customers, and the financial and strategic outcomes for the companies.

Mike Stengel is a Senior Associate at AeroDynamic Advisory, where he is responsible for project management and research of aerospace markets. His particular area of focus is in the air transport manufacturing and Maintenance, Repair, and Overhaul (MRO) sectors. Mike's projects have spanned the aerospace industry, and include topics such as aftermarket strategy, transaction/M&A advisory, customer satisfaction, strategic technology assessments, and economic development for airlines, OEMs, industry associations, and investors.

Previously, Mike was an Associate at ICF International's Aerospace and MRO consulting practice. Prior to that, he interned at United Airlines in their San Francisco, CA engine and APU maintenance facility, as well as at AeroStrategy in 2011.

Mike holds a Bachelor of Science degree in Aerospace Engineering (cum laude) from the University of Michigan, where he has also been an invited guest speaker, and is an FAA-licensed commercial pilot with an instrument rating.

Ali Yilmaz: Using (Super)Computers Judiciously for Higher Fidelity Electromagnetic Analysis (October 10, 2019 3:00pm) https://events.umich.edu/event/67638 67638-16909311@events.umich.edu Event Begins: Thursday, October 10, 2019 3:00pm
Location: Francois-Xavier Bagnoud Building
Organized By: Michigan Institute for Computational Discovery and Engineering

Abstract: Increasing the fidelity of the electromagnetic models generally increases the predictive power of the analyses based on the models. It also generally increases the results’ sensitivity to model features/parameters as well as the difficulty of constructing the models, accurately solving the governing equations, and interpreting the resulting data. Therefore, one should base the analysis on the lowest-fidelity model one can get away with or, equivalently, the highest-fidelity model one can afford. The sweet spot for the tradeoff, “the appropriate model”, has changed over time in part because past successes in simulation-based science and engineering have increased expectations/requirements from electromagnetic analysis and in part because tremendous improvements in computing infrastructure and advances in computational methods have increased the affordability of complex analysis. Finding the appropriate model requires understanding both the benefits and the costs of analysis when a lower- or higher-fidelity model is used; neither side of the ledger, however, is known beforehand (unless one is repeating previously established analyses). A possible approach to revealing these unknowns is to construct models by gradually increasing their fidelity, performing analysis at each fidelity level, and comparing the analysis results and costs to those from the previous steps. I will show examples of this “analysis-driven modeling” in bioelectromagnetics (using the AustinMan and AustinWoman human body models) and signal integrity (using an electronic package example) by employing parallel algorithms and advanced integral-equation solvers on leading-edge supercomputers.

The examples will highlight many of the challenges arising from this approach to modeling. An important one is that “the appropriate method” of analysis generally depends on the model, e.g., a method can outperform alternatives for low-fidelity models but underperform them for high-fidelity ones; indeed, inappropriate (but convenient) methods can not only inflate the cost side of the ledger but also deflate the benefit side, leading to misjudgment of the appropriate model fidelity. Thus, not surprisingly, the development of appropriate electromagnetic models and appropriate computational methods are tightly linked (aka “if all you have is a hammer, everything looks like a nail”). Unfortunately, evaluating computational methods to find the appropriate one for a given model is surprisingly difficult, even for unbiased experts, as method performances depend not just on the models but also on the computers, the software realizations of the methods, and the users/developers of the software. On the one hand, theoretical comparisons (e.g., of asymptotic complexities, error convergence rates, parallel scalability limits) are often incapable of factoring in the large impact of software and hardware infrastructure on the realized/observed performance of a computational method—a problem that has worsened as the traditional Dennard scaling of clock frequencies ended in the last decade. On the other hand, empirical comparisons are beset by the same problems that physical measurements face (including irreproducible and uncertain results), require many (potentially low-efficiency) computations, and suffer from the large number of alternative methods. I will discuss whether benchmark suites can improve the judicious use of computational methods for electromagnetic analysis and what the necessary ingredients for such benchmarks are.

Venkat Raman
Professor, Department of Aerospace Engineering
University of Michigan

Ever since the start of the microprocessor and high performance computing revolution more than four decades ago, supercomputing and computational propulsion have remained indistinguishable. The overall thinking was that scientific exploration is the path to economic prosperity, and applying the emerging high performance computing capability to a problem of national interest - aircraft propulsion - will provide an edge in an increasingly competitive environment. The relationship was strengthened when the US signed (but did not ratify) the comprehensive nuclear test ban treaty (CTBT). The methods and tools needed to ensure stockpile readiness could be directly tested using computational propulsion as a surrogate problem. Leading OEMs (P&W, GE, Rolls Royce) seized this opportunity, leading to transformative design processes, the impact of which is seen in the phenomenal advances in aircraft engine performance in the last three decades.

In the last decade, there has been a change in the governing philosophy for computing. It is now seen that computing should support industrial leadership, which is deemed the path for economic success. While this may seem abstract, the effect is that computing is seen as a way to accelerate decision making in the industrial context. Driven by Silicon Valley’s increasing dominance over the use of computations, emerging supercomputing architectures are geared towards processing large volumes of data. This has important implications for computational propulsion. For instance, the path towards computations-based certification of alternative fuels may no longer be possible. At the same time, new opportunities have emerged. This talk discusses the nuances of this new era of supercomputing and its role in computational sciences.

This talk is based on a recent article by the speaker: “Emerging Trends in Numerical Simulation of Combustion Systems”, Hassanaly and Raman, Proceedings of the Combustion Institute, Volume 37, Issue 2, 2019, Pages 2073-2089.

About the speaker...
Venkat Raman received his PhD from Iowa State University in 2003 in the department of chemical engineering. He was a NASA/Center for Turbulence Research Postdoctoral Fellow at Stanford University from 2003-2004, and a research associate in the Center for Integrated Turbulence Simulations from 2004-2005.

From 2005-2014, he was on the faculty of Aerospace Engineering and Engineering Mechanics Department at The University of Texas at Austin, initially as an assistant professor (2005-2011) and later as tenured associate professor (2011-2014).

Raman received an NSF CAREER award in 2008, a distinguished paper award at the International Combustion Symposium in 2013, and the Moncrief Grand Challenge Award in 2013. He held the Eli. H and Ramona Thornton Centennial Fellow in Engineering at UT Austin from 2013-2014.

Daniel Hastings
Department Head, MIT Aeronautics and Astronautics Cecil and Ida Green Education Professor of Aeronautics and Astronautics

The MIT Department of Aeronautics and Astronautics has been undertaking a strategic assessment of its directions. This is motivated by three forcing functions. First the creation of the College of Computing at MIT and the vision that computing broadly defined now infuses all of modern engineering. Second, the aerospace enterprise is thriving and has been undergoing a burst of entrepreneurial activity in the past few years. This is driving the democratization of air and space at scales and applications that universities can approach. Third, as the undergraduate population in the nation has become more diverse, aerospace writ large has dramatically lagged behind.

The talk will explore changes in directions to address these forcing functions and position the Department for the future.

The autonomy of robotics and space systems are fundamental issues, especially for large-scale systems with critical safety issues. Specific problems include robotic mixed-type decision-making problems and spacecraft multi-phase mission planning. We propose both off-line and online algorithms to empower autonomy in real-time.
We develop the off-line algorithm by first formulating such problems as a Quadratically Constrained Quadratic Programming (QCQP), with safety criterions as constraints directly. Subsequently, to solve the QCQP, an efficient optimization algorithm is proposed based on inexact augmented Lagrangian methods. Our algorithm admits simple subproblems with closed-form solutions, which leads to scalability and real-time applicability. Simulation results are presented to validate the effectiveness and efficacy of our algorithms.
Also, for the online algorithm, Control Barrier Functions (CBF) with forward-invariance is adopted to guarantee safety via calibrating the input from control algorithms. However, CBF in high-order systems can often encounter infeasibility due to control limitations. To address that, we learn a differentiable safety hyperplane getting the lower-order states involved. A feedback training scheme is developed to decrease the infeasibility rate recursively. Subsequently, the newly learned safety hyperplane is added as a constraint in the CBF formulation. Simulation results on path planning demonstrate the improvement of the proposed framework.

Abstract
There is a lot of excitement about the potential of smart manufacturing (aka Industry 4.0), with its associated technologies like cloud computing, big data analytics, artificial intelligence and IoT, to revolutionize the manufacturing industry. An excellent application for such “smart” technologies is the additive manufacturing, another area of Manufacturing that is gaining a lot of traction. In this talk, I will share some of my early work on smart additive manufacturing using a few case studies. I will also share an initiative I am leading on establishing a smart additive manufacturing education program at U-M. My goal is to excite you with our vision, get your feedback, and maybe bring some of you along on the journey.

The Boundary Layer Transition (BOLT) sounding rocket flight experiment will be launched in May of 2020. BOLT is designed to make detailed measurements of the boundary layer state and the onset of transition to turbulence on ascent at about Mach 5 and on descent at Mach 7.5. BOLT has a complex nose geometry, highly swept leading edges and a concave surface, which challenge the validity of conventional stability analysis methods. At Minnesota we have been developing new approaches for predicting instability growth for complex geometry flows. The seminar will discuss results and progress using high-order, low-dissipation numerical methods to perform “quiet” direct numerical simulations of the BOLT flow field. The simulations reveal four different instability mechanisms; these include with a vortical disturbance associated with boundary layer roll-up on the centerline, traveling crossflow due to boundary layer distortion near the leading edge, and a complex multi-mode instability near the trailing edge. Comparisons to the available wind tunnel data will be presented. The prospects for extending the DNS to laminar flow breakdown and transition to turbulence will also be discussed.

Asst. Professor Nick Parziale, Stevens Institute of Technology, Department of Mechanical Engineering

Reacting/high-speed flow investigation with non-intrusive optical techniques permits researchers to probe fluid flows in harsh or otherwise previously inaccessible environments. New insight into the flow physics of the wicked problems in supersonic and hypersonic flows can be had with the clever application of recent advances in laser, camera, and electronics technologies. In this talk, two examples of such efforts will be discussed. The first example is the previously unexplored boundary-layer instability on a slender cone in hypersonic, reacting flow which was characterized by the implementation of focused laser differential interferometry (FLDI). The second example is a laser-based technique that measures velocity in a high-speed gas which utilizes trace amounts of krypton for the purposes of flow tagging called Krypton Tagging Velocimetry (KTV). Example results are given for a study of supersonic shock-wave/turbulent boundary-layer interaction and characterization of Arnold Engineering Development Complex (AEDC) Hypervelocity Tunnel 9 at Mach 10 and Mach 14.

Entropy-Stable (ES) schemes have gathered a lot of attention over the last decade, especially in the context of under-resolved simulations of compressible turbulent flows, where high-order accuracy and robustness are difficult to simultaneously achieve. ES schemes can enforce a non-decreasing total entropy, in agreement with the second principle of thermodynamics. However, several challenges remain to their practical use.

The current state-of-the-art of ES schemes solves the Navier-Stokes equations for a single-component perfect gas in chemical and thermal equilibrium. This model is not appropriate in applications such as hypersonics and combustion. As a first step towards enabling such applications, we constructed ES schemes for the multicomponent compressible Euler equations. Along the way, we also extended a theoretical result on the correct local behavior of entropy-stable approximations.

While entropy-stability is valuable, it does not imply a well-behaved solution. To better understand how ES schemes may or may not improve solution quality, we revisited, in terms of entropy, two classical shock-capturing problems where stability is not the core issue. We studied the overheating anomalies typically encountered in shock reflection simulations, and the severe accuracy degradation issues of upwind-type schemes in the low Mach regime.

Hall thrusters can support a wide range of instabilities, many of which remain poorly understood but are known to play a critical role in the fundamental operation of these devices. In this work, the dominant low-frequency oscillations known as the “breathing mode” is investigated to provide a more analytically rigorous yet intuitive description of the instability. The new understanding of Hall thruster oscillations yielded by this effort can improve the reliability of these devices.

Time-resolved laser-induced fluorescence paired with an ion kinetic analysis is used to characterize the near-field and internal thruster plasma during breathing oscillations. A frequency scaling study indicates that several existing theories for the breathing mode are consistent with observed oscillation trends. However, an examination of the dynamic properties of the discharge reveals that these same theories are fundamentally inconsistent with the experimental data.

A novel physical process for the breathing mode is proposed and found to agree with the experimental findings. A model corresponding to this process is developed and shown to predict positive linear growth and realistic real frequencies. A simpler model is derived and used to produce simple analytical descriptions of the real frequency and growth of the breathing mode.

Space exploration missions are limited by the propellant available to execute maneuvers, correct trajectories and station-keep. Reducing the propellant required, can lead to longer space exploration mission lifetimes and ranges. Alternatively, replacing some propellant with more scientific instruments would yield greater scientific return. A key to reducing the propellant required is to design space missions that exploit the natural dynamics. The past decades have seen significant research in this direction, leading to novel low-energy trajectory design methods based on dynamical systems theory, opening up a whole new class of possible space exploration missions. This is still an expanding area of research, incorporating newer technologies such as solar-electric propulsion and solar sails. This seminar will primarily focus on missions around irregular bodies such as asteroids. In these regimes, the orbital and attitude dynamics are significantly more coupled than in regimes near spherical bodies such as planets, providing the possibility of using the spacecraft’s attitude to affect the orbital trajectory. A suitable gravitational model will be presented, as well as analysis to understand how the gravitational force varies with a spacecraft’s attitude, and how this can be exploited to modify the orbital trajectory. Future research directions will also be discussed.

Many autonomous systems in space missions benefit from prolonged operational time and efficient operations in a variety of long-duration missions, ranging from low-earth orbiting to interplanetary space exploration. Due to limited propellant, dynamic operating environments, complex system behaviors, and strict mission constraints, it is challenging to realize full autonomy with capabilities of sustained power supply and fuel efficient operations. Without human intervention, real-time decision-making, including both motion planning and logic/reasoning decisions, plays a critical role in assuring the reliability and performance of such a system toward accomplishing the mission objectives.

This talk will present our work on developing sophisticated modeling approach, scalable optimization algorithms, and machine learning based optimal control method that collectively contribute to advanced decision-making strategies for efficient and sustainable autonomous systems in space missions. Applications in two types of autonomous systems will be discussed. One focuses on space vehicles in complex missions involving multiphase or hybrid operations where onboard propellant is limited and timely ground support is unavailable. The other type of application is solar-powered rover that harvests energy from the environment and charges the storage batteries as backup to realize sustainable operations. The overall objective of smart decision-making for both types of autonomous systems is to realize high-level efficiency in fuel utilization or energy harvesting under dynamic environments, complex operations, and mission constraints.

Location: McDivitt Conference Room

The use of mechanical metamaterials, or metastructures, for vibration suppression has recently emerged as an approach to creating vibrationally resilient systems. Although many metastructures predict an improved performance, many have not been experimentally validated due to the previous infeasibility of manufacturing their complex geometries.

Additionally, existing research has only considered designs excited in one or two directions. This research successfully designs and fabricates the first multi-axis mechanical metamaterial design capable of attenuating vibration in three directions of excitation (longitudinal, transverse, and torsional) and experimentally validates its performance against FEM and analytical models.

This work analyzes cases where using a highly damped material will outperform an optimized geometry and determines a dividing line between material damping and vibration absorption in mechanical metamaterial design. These criteria can help determine whether it is necessary to undergo costly geometric optimization processes.

The peak separation capabilities of the multi axis mechanical metamaterial are considered for augmentation through a control system located on the distributed absorber system. A pole placement control system was introduced to adjust the natural frequencies of the absorbers. Additional insight on control use in mechanical metamaterials is discussed, including recommendations on when an active control system should be considered.

Ambitious goals have been set for future transport aircraft to ensure the sustainability of the aviation industry. This includes a better than 70% reduction in fuel burn. These challenging goals require disruptive technologies beyond the current evolutionary trends. One approach being explored is the use of electric/hybrid-electric propulsion. Small electric aircraft are already being produced and offered commercially, but significant challenges prevent scaling up to commercial aviation. Technology gaps include the availability of lightweight batteries, motors, generators and transmission lines. In a recent report, the National Academy of Engineers has identified power levels and specific-power targets for electrical machines to enable the electrification of different classes of aircraft. Both cryogenic and non-cryogenic machines are being pursued to meet these requirements, and significant advances have made in the last few years. Risks remain in their practical implementation in actual aircraft. This talk will describe the state of the art in airborne electrical machines, approaches for attaining higher power and efficiency, and potential challenges and opportunities in the integration of these technologies in electric/hybrid electric aircraft. Experience from a NASA NRA to develop a high specific power 1-MW motor will also be shared.

Aircraft are multidisciplinary systems that are challenging to design due to interactions between the subsystems. The relevant disciplines, such as aerodynamic, thermal, and propulsion systems, must be considered simultaneously using a path-dependent formulation to accurately assess aircraft performance. The overarching contribution of this work is the construction and exploration of a coupled aero-thermal-propulsive-mission multidisciplinary model to optimize supersonic aircraft considering their path-dependent performance.

First, the mission, thermal, and propulsion disciplines are examined in detail. The aerostructural design and mission of a morphing-wing aircraft is optimized before the optimal flight profile for a supersonic strike mission is investigated. Then a fuel thermal management system, commonly used to dissipate excess thermal energy from supersonic aircraft, is constructed and presented. Engine design is then investigated through two main applications: multipoint optimization of a variable-cycle engine and coupled thermal-engine optimization considering a bypass duct heat exchanger.

This culminates into a fully-coupled path-dependent mission optimization problem considering the aerodynamic, propulsion, and thermal systems. This large-scale optimization problem captures non-intuitive design trades that single disciplinary models and path-independent methods cannot resolve. Although the focal application is a supersonic aircraft, the methods presented here are applicable to any air or space vehicle and other path-dependent problems.

The other talks this semester will be based on research in Aerospace Sciences and Engineering. This talk is based on research in the Social Sciences - particularly Psychology, Sociology, Economics - and how it applies to education and careers in aerospace engineering.

For the past five years, I have been part of a group of Michigan professors who read this social science literature, and meet to discuss its implications on academic careers - teaching, research, service and hiring of faculty. We also give talks about why and how to improve diversity in faculty hiring to faculty throughout the university, department chairs and deans, and faculty at other universities.

In this talk, I will present some classical and recent social science research about issues that affect our ability to hire and retain a diverse and excellent faculty, particularly in STEM fields, and especially in aerospace engineering. Topics will include implicit bias, stereotype threat, accumulation of disadvantage, and some of the steps we are taking as a university to improve the composition of the faculty. I will also present data about the demographics of the aerospace field, and give you some strategies for being a part of the much-needed solution to Aerospace's diversity challenges.

Battery specific energy is now reaching levels at which electric aircraft propulsion is feasible for short ranged missions, and entirely new aviation markets are blossoming by taking advantage of the reduced operating costs of electric aircraft. Electric drones are ubiquitous, electric flight training aircraft are in production, and—ushering in the era of urban air mobility—electric urban air taxis are nearing certification.

This talk will present recent research focused on the conceptual design, analysis, and operations of electric vertical takeoff and landing (eVTOL) aircraft for urban air mobility (UAM). Specific topics include the development of a battery model appropriate for aircraft sizing and an investigation of the flight performance of canonical eVTOL aircraft configurations. Operations research topics for UAM including demand modeling, vertiport placement optimization, and flight scheduling will also be discussed. The talk will conclude by highlighting research and educational opportunities related to electric flight and urban air mobility.

Since the launch of the first satellite (Sputnik 1) in 1957, humans have created a lot of objects in orbit around Earth. The number of space objects larger than 10 cm is presently approaching 21,000, the estimated population of objects between 1 and 10cm is about 500, 000, and for objects smaller than 1cm the number exceeds 100 million. Both the number of space objects and the number of conflicts between these objects are increasing exponentially.

This talk overviews the research we have been pursuing on to address the challenges posed by the growth of space debris. We will first introduce the Modified Chebyshev-Picard Iteration (MCPI) Methods, which are a set of parallel-structured methods for solution of initial value problems and boundary value problems. The MCPI methods have been recommended as the “promising and parallelizable method for orbit propagation” by the National Research Council. The talk will then highlight our recent results to develop a methodology to predict RSOs trajectories both higher accuracy and higher reliability than those of the current methods. Inspired by the learning theory through which the models are learnt based on large amounts of data and the prediction can be conducted without explicitly modeling space objects and space environment, we are working on a new orbit prediction framework that integrates physics-based orbit prediction algorithms with a learning process. Last, we will present our research in autonomous, performance-driven, and online trajectory planning and tracking of space robotics for space debris removal with the goal to solve the problem in real time.

Model Predictive Control (MPC) is a powerful control methodology that constructs a control law from the solution of a receding horizon optimal control problem (OCP). MPC can systemically handle nonlinearities, coupling, and constraints but can be difficult to implement because of the need to solve non-linear OCPs online. One way to reduce this computational burden is to exploit that in MPC one solves a sequence of OCPs and reuse information from previous problems, a practice commonly called "warmstarting". In this talk, I discuss the theoretical, algorithmic, and practical application of warmstarting in MPC. First, I introduce Time-distributed Optimization (TDO), a unifying framework for studying the system theoretic consequence of warmstarting, which we use to derive sufficient conditions for stability and robustness. Second, I present FBstab, a quadratic programming algorithm with strong robustness properties that is designed to be warmstarted and can exploit the structure of optimal control problems. Finally, I illustrate the applicability of the these methods in the real-world, using diesel engine, autonomous driving, and guided parafoil examples.

Understanding the kinetics of molecular energy transfer and chemical reactions in nonequilibrium reactive flows and low-temperature plasmas is critical for a number of engineering applications, such as hypersonic aerothermodynamics and propulsion, high-speed flow control, plasma-assisted combustion, and plasma-enhanced catalysis. Non-intrusive laser diagnostics is critical for probing these environments, where chemical reaction pathways and internal energy relaxation are strongly affected by the applied electric field and by the number densities of excited molecular and atomic species. This talk presents recent results on characterization of reacting molecular plasmas in a slow flow reactor and in a supersonic wind tunnel. The plasmas are sustained by a ns pulse discharge combined with DC or RF voltage waveforms, which improves the plasma stability at high pressures and enables selective generation of vibrationally and electronically excited molecules, as well as atomic species and radicals. Electric field, gas temperature, vibrational level populations of diatomic molecules, and number densities of excited metastable electronic states in these plasmas are measured by Electric Field Induced Second Harmonic (EFISH) generation, Coherent Anti-Stokes Ramas Scattering (CARS), Cavity Ring Down Spectroscopy (CRDS), and Tunable Diode Laser Absorption Spectroscopy (TDLAS). These data provide detailed insight into kinetics of ionization, vibrational relaxation, quenching of excited electronic states, molecular dissociation, energy thermalization (“rapid heating”), and plasma chemical reactions, as well as their coupling to the reacting flow.

Collaborative autonomous vehicles hold the promise to revolutionize transportation, disaster response, and space exploration. Already, micro-aerial vehicles with on-board cameras have become a multi-billion-dollar industry; and as we enter the new decade, teams of semi-autonomous flying cars, jet fighters, and space-exploration vehicles are being launched. An era of ubiquitous aerospace vehicles is becoming a reality, and along with it autonomous vehicles that can form teams, agree on navigation plans, and perceive the world. However, this future is threatened by denial-of-service (DoS) and deceptive attacks and failures that can compromise the vehicles’ teams, navigation plans, and perception capabilities. These threats lie outside the reach of cybersecurity, and of estimation and control against malicious data. Instead, algorithms at the intersection of perception, planning, and non-convex optimization are needed. I will present two algorithms from my research, and my vision for a resilient collaborative autonomy.


First, I will discuss the first provably optimal algorithms for robust combinatorial optimization against any numbers of DoS attacks. The algorithms can robustify for the first time teams and their navigation plans against DoS attacks. I will demonstrate this via search and rescue, and surveillance experiments. Second, I will present algorithms that robustify visual perception capabilities against deceptive failures (outliers). The algorithms achieve extreme outlier-robustness in near real-time for the first time. I will illustrate this across various perception problems, on datasets for localization and mapping (SLAM), object recognition, and 3D-reconstruction. I will conclude with my vision for a collaborative autonomy that is not only robust but also resilient: I will argue the need for a technological convergence between (i) “cyber” capabilities for a distributed artificial intelligence, driven by adaptive learning and data-driven perception and navigation algorithms, and (ii) “physical” capabilities of morphable structures, self-healing materials, and smart devices.

Modern cyber-physical systems, such as drone formation, robot swarms, and transportation systems, can be of large scale and have sparse and distributed control logic due to limited information exchange. Many control and computational problems of practical interest remain unsolved due to the issues of non-convexity and complexity. The first part of this talk focuses on how to recover convexity for distributed control problems. I will present a new distributed control framework centered on the notion of sparsity invariance, which allows deriving convex approximation/reformulation of the largest known class of distributed control problems with sparsity constraints. I will show that the notion of sparsity invariance goes beyond the well-known notion of quadratic invariance. The second part of this talk focuses on the scalability of solving large-scale convex optimization problems. In particular, I will consider the class of semidefinite optimization problems. By exploiting the properties of chordal graphs and sparse positive semidefinite matrices, I will present a decomposition method that can scale sparse semidefinite optimization to large-scale instances, achieving massive scalability. The resulting algorithms have been implemented in the open-source solver: CDCS (Cone Decomposition Conic Solver). Extensions to a class of polynomial optimization, i.e., sparse sum-of-squares optimization, will be briefly discussed.

A detailed understanding of plasma physics is critical to overcoming physics and engineering challenges such as those posed by long-duration operation of electric propulsion devices and the development of nuclear fusion concepts. At the Plasma Dynamics Computational Laboratory at Virginia Tech, we study fundamental processes such as plasma sheath physics and plasma-material interactions to support and overcome some of the physics challenges of advanced space propulsion concepts. Furthermore, nuclear fusion, which remains one of the biggest unsolved problems of the previous and present centuries, may hold the key to long-duration, high-payload spaceflight in addition to potentially satisfying terrestrial energy demands. Research at the laboratory also supports a wide array of fusion concepts including magnetic confinement fusion, magneto-inertial fusion, and inertial confinement fusion. The high-energy-density hydrodynamics research being performed to study these concepts extends to astrophysics and national security applications. A common challenge across these varied applications is the necessity for high-fidelity computational models for kinetic and fluid plasmas. Recent advances in plasma modeling, from magnetohydrodynamic to fully kinetic, will be presented. This research seminar will describe novel kinetic and multi-fluid models and will discuss original research contributions in two representative applications: plasma-material interactions relevant to plasma thrusters and high-energy-density hydrodynamics.

Predicting what happens as a hypersonic vehicle flies through the atmosphere involves a lot of interesting physics. The strong shock wave, generated ahead of the vehicle, superheats the air to thousands of degrees and partially dissociates the air into atomic oxygen and nitrogen. Surrounded by this high-temperature shock layer, the vehicle heat shield experiences large heating rates and must simultaneously withstand high temperatures and intense surface chemistry driven by reactive atomic species. Furthermore, as the shock-heated gas flows around the vehicle, the flow can transition from smooth laminar flow to chaotic turbulent flow and can form complex shock interactions near control surfaces. Predicting such effects requires understanding the interplay between fluid dynamics, thermodynamics, and chemical kinetics; a research field referred to as aerothermodynamics.

In this talk, I will focus mainly on our current understanding of the high-temperature shock layer. I will explain how we have reached the point where this thin shock layer (often on the order of one centimeter thick) can be studied at the scale of individual molecular collisions. In fact, simulations can now be performed where the only model input consists of the forces between atoms as dictated entirely by quantum chemistry. I will present results from such first-principles simulations along with comparison to experimental shock-tube data, and I will discuss some of the new physical insights gained. I will conclude the talk by highlighting the next big challenge of pursuing molecular understanding for gas-material interactions. This is an exciting field driven not only by NASA and the Department of Defense, but also by commercial endeavors to field satellite mega-constellations in low Earth orbit.

Advanced Persistent Threats (APTs) are sophisticated attacks mounted by intelligent and resourceful adversaries who gain access to a targeted system and gather critical information over an extended period of time. APTs consist of multiple stages, including initial system compromise, privilege escalation, and data exfiltration, each of which involves strategic interaction between the APT and the targeted system. While this strategic interaction can be viewed as a game, the stealthiness, adaptiveness, and unpredictability of APTs imply that the information structure of the game and the strategies of the APT are not readily available. In this talk, we will present a game-theoretic approach to characterize the trade-off between effectiveness for detecting APTs and resource efficiency. Our approach to modeling APTs is based on the insight that the persistent nature of APTs introduces information flows in the system that can be monitored. One monitoring mechanism is Dynamic Information Flow Tracking (DIFT), which taints and tracks suspicious information flows through a system and performs security analysis on the tainted flows at designated locations. Since performing security analysis on all the flows will incur significant memory and performance overhead, efficient defense policies are needed to maximize the probability of detecting the APT while minimizing resource costs. In this work, we develop a multi-stage game framework for modeling the interaction between an APT and a DIFT, as well as designing an efficient DIFT-based defense. Our model is grounded on APT data gathered using the Refinable Attack Investigation (RAIN) flow-tracking framework. We will present the current state of our formulation, insights that it provides on designing effective defenses against APTs, and directions for future work.

Earth satellite orbits can possess an extraordinarily rich spectrum of dynamical behaviors, from stable resonant configurations to significant chaotic drifts in circumterrestrial phase space throughout their orbital lifetimes. This talk will review these intriguing phenomena and highlight their deeper connections with current aspects of space sustainability, space traffic management, and space situational awareness. One particularly compelling ideology is based on the judicious use of the resulting instabilities to prescribe natural Earth re-entry itineraries to remedy the space debris problem or to navigate the phase space. In this seminar, I will review recent theoretical and numerical investigations on the orbital dynamics of resident space objects, and show how resonances can profoundly affect the behavior of these bodies, in both dissipative and Hamiltonian settings.
This work ties together observation, theory, and simulation, and fosters connections between fields apparently quite different in character and emphasis. I will specifically note its cross-cutting nature and relevance to planetary science, applied dynamical systems theory, planned and proposed spacecraft missions, and satellite constellation design and control.

Dr. H. Jane Bae
The currently available computational power limits the utilization of direct numerical simulation (DNS) in practical engineering flow applications. In recent years, large-eddy simulation (LES) has emerged as a viable high-fidelity tool for such flow problems; however, it suffers from the same computational limitations in the near-wall region. In this talk, I will introduce a new way of modeling the wall in LES to overcome the limitation of the near-wall region. First, the use of the slip boundary condition with transpiration for wall-modeled LES is motivated by theoretic assessment and a priori testing using DNS data. Secondly, a dynamic slip wall model consistent with the constant stress layer in the near-wall region is presented. The dynamic slip wall model is free of any a priori specified coefficients, unlike traditional wall models which are based on RANS models. The results show that the predictions of the mean velocity profile and turbulence intensities from the dynamic slip wall model are in good agreement with DNS and experimental data for a wide range of Reynolds numbers and grid resolutions for canonical turbulent boundary layers.

The past twenty years have seen rapid improvements in the performance of small unmanned aerial vehicles as well as the continued miniaturization of low-cost sensors. The intersection of these technologies has given rise to a renaissance of control and decision-making developments geared towards mobile wireless sensor networks (MWSNs). One such development, dynamic coverage control, enables MWSNs to rapidly explore and gather information from uncertain environments. This defense will overview contributions to dynamic coverage in environments containing information decay, stochastic intruders, and power-constrained vehicles.

The extension of coverage to collaborative networks of humans and aerial/space robots shall also be presented. The author considers a human wearing an augmented reality (AR) device while completing multiple interdependent tasks that are time-sensitive and spatially separated. The problem of coverage is here coupled to that of human intent inference. An aerial robot shares the environment and uses machine learning in order to determine both the locations of tasks as well as their temporal context. This enables the streaming of real time task images that are beyond the human’s field of view to their AR display. In such a way, the human can instantaneously cover a greater volume of the environment than is naturally possible.
