Lockheed Martin Hypersonic ATACMS Motor Boosts Experimental Scramjet in First Flight
Lockheed Martin announced today that its Army Tactical Missile System (ATACMS) rocket motor successfully boosted the experimental X-51A WaveRider beyond Mach 4.5, the speed at which a scramjet will start and begin to provide thrust.
The successful boost helped the X-51 hypersonic scramjet engine to accelerate to a historic Mach 5, a first for the vehicle.
The X-51 WaveRider is an unmanned aerial vehicle designed for extended hypersonic flight durations. The successful boost with the ATACMS rocket motor will allow for future advancements in hypersonic flight.
