Aerospike Engine Makes First Flight
LOS ANGELES NASA’s Lockheed SR-71 has made the first of a series of flights in support of the X-33 program, carrying a subscale linear aerospike rocket engine piggyback to test it under different flight conditions. The Oct. 31 flight from Dryden Flight Research Center, Edwards AFB, Calif., was an envelope clearance and systems test flight and did not operate the Boeing Rocketdyne Div. engine, though the propellant tanks were pressurized with inert gas.
