This paper provides an overview of NASA's current focused hypersonic technology program, called the Hyper-X Program. The Hyper-X Program, a joint NASA program executed by the Langley Research Center and the Dryden Flight Research Center, is designed to move hypersonic, air breathing vehicle technology from the laboratory environment to the flight environment, the last stage preceding prototype development. The Hyper-X research vehicle will provide the first ever opportunity to obtain data on an airframe integrated scramjet (supersonic combustion ramjet) propulsion system at true flight conditions and the first opportunity for flight validation of experimental wind tunnel, numerical and analytical methods used for design of this class of vehicles. A substantial portion of the program is experimentally based, both for database development and performance validation. At this time wind tunnel testing of the flight engine on a "full forebody" simulation and complete airframe integrated scramjet configuration flowpath is expected this year (1998) and in 1999, respectively, and the first flight test, at Mach 7, is planned for 2000. This paper addresses ground and flight testing aspects of the Hyper-X program, with some discussion on flight data utilized. |
