                    By 88th Air Base Wing Office of Public Affairs
            **WRIGHT-PATTERSON AIR FORCE BASE, Ohio (AFNS) --**A team of researchers from the Air Force Research Laboratory, NASA and FlexSys Inc., accomplished a long sought goal in aviation research April 22, with the last flight of the Adaptive Compliant Trailing Edge (ACTE) Flight Research program.
A radically new morphing wing technology called FlexFoil exceeded all expectations in flight testing. The ACTE program completed 22 research flights between Nov. 6, 2014, and April 22, at NASA Armstrong Flight Research Center on Edwards Air Force Base, California.
Positive results from the flight tests indicate that FlexFoil , which can be retrofitted to existing aircraft wings or integrated into entirely new airframes, is ready to revolutionize aircraft wing design. The technology enables engineers to reduce wing structural weight and to aerodynamically tailor the wings throughout the flight envelope to promote improved fuel economy and more efficient operations, while reducing environmental and noise impacts. 
AFRL began work with FlexSys Inc., of Ann Arbor, Michigan, in 1998, through the Small Business Innovative Research (SBIR) program. AFRL and FlexSys Inc. developed and wind-tunnel tested several wing leading and trailing edge designs for various aircraft configurations through 2006.
In 2009, AFRL and NASA’s Environmentally Responsible Aviation (ERA) project agreed to equip a Gulfstream III jet with new flap surfaces designed and built by FlexSys Inc., incorporating its proprietary FlexFoil Variable Geometry technology.
After seeing a morphing wing demonstration, Maj. Gen. Tom Masiello, the AFRL commander, said, “Here’s another example of a successful government research partnership with small business to advance a very exciting aerospace technology for transition.”
Flight testing was key to proving the concept’s airworthiness. The Gulfstream III was flown with its experimental surfaces at flap angles ranging from -2 degrees up to 30 degrees. Initial ACTE flight testing supported one of ERA’s eight integrated technology demonstrations to explore design improvements for reducing drag, weight, noise, emissions and fuel consumption. 
“The purpose of these tests was to see if flexible trailing edge wing flaps could improve aerodynamic efficiency and reduce the noise generated during takeoffs and landings,” said Fay Collier, the ERA project manager.
Pete Flick, the AFRL program manager at Wright-Patterson AFB, added, “We are thrilled to have accomplished all of our flight test goals without encountering any significant technical issues. These flights cap 17 years of technology maturation. The technology is now ready to dramatically improve aircraft efficiency for the Air Force and the commercial aviation industry.”
Sridhar Kota, inventor of FlexFoil technology and founder of FlexSys Inc., was equally enthusiastic. 
“Thanks to AFRL for its vision and leadership in recognizing the merits of our technology 17 years ago and supporting the development all the way through these flight tests, and thanks to NASA for its expertise and contributions in conducting the flight test,” said Kota, who is also a professor of mechanical engineering at the University of Michigan.Adaptive Compliant Trailing Edge
