Edmund W. Pendleton
Edmund W Pendleton (born 1956) 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.[citation needed] While employed there, he worked in the aeroelasticity group and conducted wind tunnel research[1][2][3][original research?] leading up to the Grumman X-29, the X-30 National Aerospace Plane, and the X-53 aircraft programs.[citation needed] He was one of the original developers of the active aeroelastic wing concept,[4][5][6] 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 .[7][original research?]of the X-53 Active Aeroelastic Wing flight research program from 1992 through 2005.[8][original research?] The Active Aeroelastic Wing project received a NASA "Turning Goals into Reality Award" in 2004.[9][10]
Mr. Pendleton was also active in quantifying the effects of aerodynamics on the twin tails of fighter aircraft.[11]
[12][original research?]
Pendleton earned his bachelor's degree in systems engineering from Wright State University in Fairborn, Ohio in 1979[13][original research?] and a commercial pilot's licence in 1981.[14][original research?] Pendleton earned a master's degree in aerospace engineering from the University of Dayton[15][original research?] in Ohio and his flight instructor’s certification in 1984.[16][original research?] From 1984 through 2012, Pendleton taught flying at the Wright Patterson AFB Aero Club where he taught many students who became private pilots, some of whom went on to fly professionally for the airlines and the Air Force.[citation needed] In 1998, Pendleton graduated from the Defense Systems Management College’s Advanced Program Manager’s Course.[17][original research?] and in 2003, earned a master's degree in national security strategy from the National Defense University located in Washington DC.[18][19][original research?]
In 2005, he became involved in efforts to provide technology for an Air Force Research Lab initiative entitled "Operationally Responsive Space".[citation needed] 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.[20][21][22][23][24][25][26][original research?] This initiative will pave the way for increased the structural efficiency of future Space Launch Vehicles.[citation needed]
In 2013, Pendleton became involved with a Defense Advanced Research Agency (DARPA) program / team to develop an experimental reusable spaceplane/ booster called XS-1 spaceplane.[citation needed] XS-1 is a reusable first stage booster intended to throw up to 3000 lbs into low earth orbit and fly as frequently as 10 times in 10 days.[27] Pendleton served as the DARPA contracting officer's technical representative.[28][citation needed] The XS-1 program completed its first phase where candidate flight concepts and associated technology developments were matured. Phase II of the program will complete the design, fabrication, assembly, and flight of the XS-1 small launch booster.[29][original research?]
Pendleton served on a NATO technical panel for aerospace structures and materials where he coauthored several papers.[30][31][citation needed][original research?]
Pendleton has been a registered Professional Engineer in the State of Ohio since 1984.[32][33][original research?]
