“…ITH the advent of the Environmentally Responsible Aviation Project (ERA), NASA has showed its continued support for the need to research technologies that will enable the next generation of regional commercial transports to fly quieter, on less fuel, and produce fewer emissions. Increased congestion at airports, and noise regulations have prompted NASA to evaluate how short take-off and landing (STOL) capabilities can be integrated into cruise efficient geometries, enabling larger airplanes to operate within the existing infrastructure of smaller civilian airports 1 . One specific project, with goals similar to those of ERA, is a NASA Research Announcement (NRA) funded by NASA's Subsonic Fixed Wing Program (SFW).…”

Results from Cal Poly's recent wind tunnel test in the 40-by 80-foot test section at the National Full-Scale Aerodynamics Complex (NFAC) at NASA Ames Research Center are presented. AMELIA, the Advanced Model for Extreme Lift and Improved Aeroacoustics, is the first full-span cruise efficient short takeoff and landing (CESTOL) model incorporating leading-and trailing-edge blowing wing circulation control and over-the-wing mounted turbine propulsion simulators (TPS) to date. Testing of the 10 foot span model proved successful and was the result of a 5-year NASA Fundamental Aeronautics Program Research Announcement. All of the results associated with Cal Poly's effort will be available in an open-source validation database with the goal of advancing the state-of-the-art in prediction capabilities for modeling aircraft with next generation technologies, focusing on NASA's N+2 generation goals. The model's modular design allowed for testing of 4 major configurations. Results from all configurations are presented. Test data shows drastic improvements in performance are obtained when incorporating leading edge blowing. Wing stall can be delayed to more than 25° angle of attack at lift coefficients exceeding six. Without the introduction of leading edge blowing to increase boundary layer momentum and maintain flow attachment around the leading edge, STOL performance suffers. Similar runs for trailing edge-only blowing show a reduction in maximum lift coefficient to three with stall occurring at zero angle of attack. Testing at multiple engine pylon heights allowed for the highly coupled propulsion and flow control system to be characterized.
