Edmund W. Pendleton

Edmund W Pendleton is an American research and development engineer, commercial pilot, and flight instructor best known for his work on the X-53 flight research program. He joined the United States Air Force Research Laboratory in Dayton, Ohio in 1980. While employed there, he conducted wind tunnel research[1][2][3] leading up to the Grumman X-29, the X-30 National Aerospace Plane, and the X-53 aircraft programs. He was one of the original developers of the active aeroelastic wing concept,[4][5] a novel engineering design approach that utilized wing aeroelastic twist to control aircraft at high speeds. He served as a program manager and chief engineer of the X-53 Active Aeroelastic Wing flight research program from 1992 through 2005.[6][7] The Active Aeroelastic Wing project received a NASA "Turning Goals into Reality Award" in 2004.[8] Mr Pendleton was also active in quantifying the effects of aerodynamics on the twin tails of fighter aircraft[9] .[10]

Ed Pendleton attended grade school in Wayne Township, Ohio.[11] After transferring, he graduated from Beavercreek High School, Xenia Ohio, where he played on the school's basketball and baseball teams from 1972-1975[12][13] After service in the U.S. army, Ed Pendleton earned his bachelor’s degree in systems engineering from Wright State University in Fairborn, Ohio in 1979 [14] and a commercial pilot's licence in 1981.[15]

He earned a master’s degree in aerospace engineering from the University of Dayton[16] in Ohio and his flight instructor’s certification in 1984.[17][18] In 1998, Ed graduated from the Defense Systems Management College’s Advanced Program Manager’s Course.[19] In 2003, Ed earned a master’s degree in national security strategy from the National Defense University located in Washington DC.[20]

In 2005, he became involved in efforts to provide technology for an initiative entitled "Operationally Responsive Space". From 2006 through 2011, he has served as a project manager/engineer for an air/spaceframe development effort involving the integration of a low mass fraction, load bearing, cryogenic, composite, linerless fuel and oxidizer tank with lifting surfaces, thermal protection, and condition based maintenance under a Future Responsive Access to Space Technology initiative.[21][22][23][24][25][26][27] This initiative will pave the way for increased the structural efficiency of future Space Launch Vehicles.

In 2013, Ed became involved with a Defense Advanced Research Agency (DARPA) program / team to develop an experimental reusable space plane / booster called XS-1. The XS-1 program is in its first phase which will develop candidate flight concepts and associated development costs. [28]

Ed served for ten years on a NATO technical panel for aerospace structures and materials where he coauthored several papers.[29]

Ed Pendleton has been a registered Professional Engineer in the State of Ohio since 1984.[30][31]
