Fluid-Structure-Jet Interaction Effects on High-Speed Vehicles
Aerospace Engineering PhD Candidate: Ryan Kitson
Dissertation Chair: Professor Carlos Cesnik

This dissertation is focused on two design considerations for supersonic intercept missiles: (i) increased structural slenderness and (ii) attitude control jets. The resulting new designs have the potential to increase vehicle performance, but will lead to a coupled fluid-structure-jet interaction that has yet to be studied. Numerical results of the vehicle response across the design space and flight envelope can be used as guidelines for assessment of improved control effectiveness, maneuverability and agility.

First, new modeling methods for approximating the steady-state and dynamic loads are presented. The methods account for the wide range of flight conditions and maneuvering conditions. Next, multiple vehicle models with varying flexibility and fin configuration are developed to conduct high-fidelity analysis and reduced order model flight simulation.

Steady-state and dynamic high-fidelity results have presented that highlight the nonlinearity and sensitivity of fluid-structure-jet interaction to perturbations in the flight conditions and control inputs. These high-fidelity results, as well as flight simulation results of the reduced order models, reveal how fluid-structure-jet interaction can significantly affect the vehicle flight response.
