The Reduced Order Aeroservoelastic Models with Rigid Body Modes technology will increase the technical readiness of methods that can be used by NASA to support Aeronautics Research. The proposed work addresses development of efficient methods to generate mathematical models of flight vehicles currently employed in NASA research projects such as the X-53 and X-56A for performing vibration, aeroelastic, and aeroservoelastic studies. This includes design methodologies that encompass CFD steady and unsteady aerodynamics, flexible structures, and active control systems. The work will use existing methods that predict aeroelastic phenomena and complex steady and unsteady aerodynamic flow phenomena, especially in the transonic speed range. The tools, methods, and algorithms developed in the Phase I effort can be marketed to both NASA and non-NASA customers as they are applicable to vehicles such as the X-53, F/A-18C, and X-56A. The innovating firm (Systems Technology, Inc.) has long standing relationships with numerous manufacturers of both commercial and military aircraft. Specifically, the firm has long standing relationships with numerous Boeing personnel at both the Military and Commercial Airplanes divisions, as well as within Lockheed Martin's X-56A program. Furthermore, the firm has participated in research efforts both as a lead contractor and subcontractor with these entities. Beyond industry there are potential post applications within the US military. The innovating firm is aware of specific interest within the US Air Force for aeroservoelastic simulation capability in concert with active control. Because of the demands of aeroelastic analysis and testing at the Air Force Flight Test Center at Edwards AFB and other military facilities such as the Air Armament Center at Eglin AFB and the Naval Air Warfare Center Weapons Division at China Lake, the capabilities can aid in flight test analysis, assessment and safety.
