Description
Summary:Hariharan presents the military's advances on vertical flight. The US Army Aviation Development Directorate and industry partners flight tested two Joint Multi-Role Technology Demonstrator rotorcraft--the Bell V280 Valor air vehicle concept demonstrator and the Sikorsky-Boeing SB>1 Defiant--to demonstrate advanced technologies and prepare the Army for the Future Vertical Lift acquisition program. Army researchers worked with Bell, Sikorsky-Boeing, California-based Karem and South Carolina-based AVX to perform high-fidelity, high-performance computing physics-based modeling with the High Performance Computing Modernization's CREATE-AV Helios rotorcraft software to predict performance and better understand interactional aerodynamics. CREATE is short for the Computational Research and Engineering Acquisition Tools and Environments program. Results from the physics-based models are being compared with test data from both ground and flight tests as it becomes available to better understand the aircraft.
