#WASHINGTON — #Rocket propulsion startup Ursa Major announced March 9 its Hadley engine successfully flew for the first time powering a Stratolaunch #hypersonic test vehicle.
Stratolaunch operates a giant aircraft — a modified version of a double-fuselage Boeing 747-400 — that serves as a mobile launchpad. It carries hypersonic vehicles underneath its center wing until reaching the desired altitude. This allows hypersonic vehicles to reach higher speeds before ignition and avoids the complexities of ground launching
The March 9 test off the coast of California, over the Pacific Ocean, was the first powered flight of Stratolaunch’s Talon hypersonic test vehicle. The company said the vehicle reached high supersonic speeds approaching Mach 5, or five times the speed of sound.
