WASHINGTON — Rocket propulsion startup Ursa Main introduced March 9 its Hadley engine efficiently flew for the primary time powering a Stratolaunch hypersonic test vehicle.
Stratolaunch operates a large plane — a modified model of a double-fuselage Boeing 747-400 — that serves as a cellular launchpad. It carries hypersonic automobiles beneath its middle wing till reaching the specified altitude. This permits hypersonic automobiles to achieve larger speeds earlier than ignition and avoids the complexities of floor launching
The March 9 test off the coast of California, over the Pacific Ocean, was the primary powered flight of Stratolaunch’s Talon hypersonic check automobile. The corporate mentioned the automobile reached excessive supersonic speeds approaching Mach 5, or 5 occasions the pace of sound.
Ursa Main founder and CEO Joe Laurienti mentioned hypersonic flight “has been a large army and governmental problem” and personal corporations are actually advancing this important nationwide mission. The U.S. army mentioned there’s a growing demand for hypersonic test capabilities in an effort to ramp up the event of next-generation weapon programs.
Laurienti mentioned the flight of the Stratolaunch Talon TA-1 check automobile marks a significant milestone for the Hadley, a 5,000-pound-thrust liquid oxygen and kerosene, oxygen-rich staged combustion cycle rocket engine.
Based mostly in Berthoud, Colorado, Ursa Main manufactures liquid engines for small area launchers and hypersonic automobiles, and not too long ago introduced plans to broaden into strong rocket motors.
The corporate uses 3D printing to hurry up the manufacturing course of, and claims it will possibly construct engines in a matter of days.
