X-43A: Full Speed Ahead to Mach 10
EDWARDS, CALIFORNIA -- Engineers here are on the fast-track, readying the next flight of NASA’s X-43A, a super-sleek, high-speed craft powered by a scramjet engine.
Earlier this year, the unpiloted 12-foot-long, 5-foot-wide surfboard-looking vehicle howled its way into the history books. The X-43A reached its test speed of Mach 7 -- seven times the speed of sound, or about 5,000 miles per hour. In doing so it set a world-record speed for “air-breathing” flight, the rocket technology advanced by NASA’s Hyper-X program.
But on a successful second flight, the X-43A flew freely for several minutes following scramjet engine operation. The vehicle's supersonic combustion ramjet, or scramjet, ignited as planned and operated for the duration of its hydrogen fuel supply.
Now it’s full speed ahead to Mach 10.
