Officials at NASA’s LaRC announced that they had completed a series of 11 tests on the Pratt & Whitney Rocketdyne SJX61-2 scramjet engine in the 8-Foot High Temperature wind tunnel. The tests had been NASA’s contribution to the mission to build the X-51 WaveRider aircraft. The design of the X-51 WaveRider would enable the craft to travel at speeds near Mach 7 for approximately 5 minutes. The U.S. Air Force Research Laboratory and U.S. Defense Advanced Research Projects Agency had been the main contributors to the US$246 million X-51 project. LaRC had tested a combined cycle, jet-fueled, air-breathing, flight-clearance engine, similar to the engine that the X-51would use. NASA engineers expected that they would complete testing by the end of September 2008.
