NASA technician James Fay prepares a hypersonic model for wind tunnel tests at NASA Langley Research Center.
Research involving the development of futuristic hypersonic aircraft has yielded a new aircraft concept known as the"waverider." Waverider aircraft would be capable of flight at speeds ranging from Mach 4 to Mach 6.
The waverider series, to be powered by airbreathing hypersonic engines, have been envisioned as cruise missile carriers, high altitude reconnaissance vehicles, and long range strike and transport aircraft.
A swept-wing Mach 5 configuration known as the LoFlyte was developed for preliminary studies under the auspices of the NASA Small Business Innovative Research program. To supplement testing in the high-speed regime, subsonic low-speed wind tunnel tests were required.
A 0.062-scale, 8-ft.-long LoFlyte model was built by the Accurate Automation Corporation of Chattanooga, Tenn., and tested in NASA Langleys 12-ft. Low-Speed Tunnel and 30 x 60-ft. Full-Scale Tunnel. The studies revealed that the configuration is aerodynamically sound through the low-speed regime.
The tests were some of the last to be performed in Langleys historic 30 x 60-ft. Full-Scale Tunnel. The tunnel, designated a National Historic Landmark in 1985, will be officially closed Sept. 29.
