In 1987, Peter Masak called on Maughmer about designing winglets for his sailplane to improve performance. Others had attempted to apply Richard T. Whitcomb's NASA winglets to gliders, and though they did improve climb performance, this did not offset the parasite drag penalty in high speed cruise. Masak was convinced it was possible to overcome this hurdle, and Maughmer was willing to join his quest.
By trial and error, they ultimately developed successful winglet designs for gliding competitions, and at the 1991 World Gliding Championships in Uvalde, Texas, the trophy for the highest speed went to a winglet equipped 15-meter class limited wingspan glider, exceeding the highest speed in the unlimited span Open Class, an exceptional result.[2]
The winglets were originally retrofit to production sailplanes, but now most high-performance gliders are equipped from the factory with winglets, or some other wingtip device.[3] Maughmer has consulted with German sailplane designers on winglets, non-planar wing tips, and other aerodynamic improvements incorporated in several production sailplanes.[citation needed]
He received his Ph.D. (Aeronautical and Astronautical Engineering) from the University of Illinois in 1983, M.S. from Princeton University in 1975 and B.S. from the University of Illinois in 1972. Maughmer received the PSES Outstanding Teaching Award in 1993, the PSES Premier Teaching Award in 2001, and the Alumni Faculty Teaching Fellow Award in 2012. In 2009, Maughmer received the ASEE Fred Merryfield Design Award, a national award for teaching excellence in engineering design. He is active in the AIAA and has served on the Aircraft Design Technical Committee (1987–90). He received the AIAA/ASEE John Leland Atwood Award in 2013, and the AIAA William T. Piper Award in 2014. For the Soaring Society of America, he is chair of configuration and design for the Technical Board, serves on the board of directors for the Collegiate Soaring Association, and received the society's Exceptional Service Award in 1991. He has served on the Board of the International Organization for the Science and Technology of Soaring (OSTIV), and is currently the vice-president of that organization. He is also a glider pilot and a flight instructor with the Penn State Soaring Club.
