Boeing – The experimental X-51A WaveRider aircraft, powered by a scramjet engine designed to reach hypersonic speeds, did just that as it hit Mach 5, which is nearly 4,000 miles per hour. It flew for a total of six minutes, and three and a half of those minutes were with the scramjet engine, breaking its own record from its first flight in 2010 when the WaveRider flew for 143 seconds.
The X-51A WaveRider is an unmanned, autonomous supersonic combustion, ramjet-powered hypersonic flight-test demonstrator for the U.S. Air Force. The X-51A demonstrates a scalable, robust endothermic hydrocarbon-fueled scramjet propulsion system in flight, as well as high temperature materials, airframe/engine integration and other key technologies within the hypersonic range of Mach 4.5 to 6.5. more> http://tinyurl.com/d2pzp66
