Omnisonic Mechanics

This research is to increase the understanding of the highly nonlinear and unsteady flow physics associated with complex, precision munitions as they maneuver through the atmosphere at subsonic through hypersonic speeds; and determine how best to integrate the predicted physics into the aerodynamic models and flight control laws. Emphasis of the research will focus on high-fidelity computational fluid dynamics (CFD) predictions of nonlinear flow interactions generated by control actuators (e.g., canard trailing vortices, reaction jet plumes, shock-boundary layer interactions) or flight-vehicle maneuver motions (e.g., forebody vortices, shock-shock interactions); evaluation of active or passive flow control techniques; and development of nonlinear flight-control algorithms.
