#OTD 26 May 2010 at Edwards - The X-51A “Waverider” Scramjet Engine Demonstrator vehicle made the longest ever supersonic combustion ramjet-powered hypersonic flight in a the mission performed off the coast of southern California. The approximately 150-second burn by the X-51A’s Pratt & Whitney Rocketdyne-built air breathing scramjet engine accelerated the test vehicle to approximately Mach 4.9. The previous longest scramjet burn in a flight test was 12 seconds. U.S. Air Force officials called t

This rare footage shows NASA testing the X-43A, an experimental hypersonic aircraft built to explore extreme-speed flight. Because scramjet engines cannot start from rest, the vehicle was carried under a B-52, boosted to hypersonic speed by a rocket, and only then ignited its own engine. | SpaceEve

India achieves a major milestone by successfully testing an active-cooled hypersonic scramjet engine, making it the fifth country to do so. This breakthrough enhances defense capabilities and supports ISRO’s future space missions.
