Public award description

THIS RESEARCH SUPPORTS NASA S AVIATION SAFETY PROGRAM, INTEGRATED RESILIENT AIRCRAFT CONTROLS PROJECT (IRAC) AND FUNDAMENTAL AERO PROGRAM, SUBSONIC FIXED WING PROJECT (SFW). ONE COMMON OBJECTIVE FOR THESE PROJECTS IS TO EXTEND THE FIDELITY OF AERODYNAMIC MODELS SO THAT AIRCRAFT RESPONSES IN NONLINEAR UNSTEADY PORTIONS OF THE FLIGHT ENVELOPE CAN BE ACCURATELY PREDICTED. BOTH PROJECTS ARE SUPPORTING FUNDAMENTAL FLIGHT DYNAMICS DEVELOPMENT BUT SFW HAS A BROADER SCOPE INCLUDING ADVANCED AND NEXT GENERATION AIRCRAFT CONFIGURATIONS WHILE IRAC IS MORE SPECIFICALLY FOCUSED ON TRANSPORT CONFIGURATIONS. A KEY PRODUCT OF IRAC AND SFW FLIGHT DYNAMICS RESEARCH WILL BE A COMPREHENSIVE MODELING METHODOLOGY FOR OBTAINING MORE GENERAL AIRCRAFT AERODYNAMIC MODELS OVER AN EXPANDED FLIGHT ENVELOPE. THE METHODOLOGY WILL DEFINE GROUND AND FLIGHT TEST TECHNIQUES, MATHEMATICAL MODEL STRUCTURES FOR CURRENT AND ADVANCED CONFIGURATIONS, AND IDENTIFICATION ALGORITHMS FOR OBTAINING THE MATHEMATICAL MODELS FROM MEASURED DATA.
