Pratt & Whitney Rocketdyne scramjet powers record-breaking flight of X-51A WaveRider

CANOGA PARK, Calif. – The X-51A WaveRider hypersonic vehicle, powered by Pratt & Whitney Rocketdyne’s SJY61 scramjet engine, achieved aviation history on May 1 by making the longest-ever supersonic combustion ramjet-powered flight, flying full duration and achieving mission success.

Pratt & Whitney Rocketdyne is a United Technologies Corp. company.

“This test flight brings aviation closer than ever to the reality of regular, sustained hypersonic flight,” said Jim Maser, president of Pratt & Whitney Rocketdyne.  “We are very proud to be part of the team that made this possible.”

“The X-51A is a critical element in our progression to practical hypersonic propulsion, providing a greater understanding of hypersonic propulsion performance, control and structural durability,” said George Thum, X-51A program manager, Pratt & Whitney Rocketdyne.

The X-51A program is a collaborative effort of the U.S. Air Force Research Laboratory, the Defense Advanced Research Projects Agency (DARPA), Boeing and Pratt & Whitney Rocketdyne.

“It was a full mission success,” said Charlie Brink, X-51A program manager for the Air Force Research Laboratory Aerospace Systems Directorate.  “I believe all we have learned from the X-51A WaveRider will serve as the bedrock for future hypersonics research and ultimately the practical application of hypersonic flight.”

During this, the X-51A’s fourth and final planned flight, the unmanned WaveRider vehicle was carried beneath the wing of a U.S. Air Force B-52 and dropped from an altitude of about 50,000 feet over the Pacific Ocean off southern California.  A solid rocket booster fired and propelled the cruiser to scramjet takeover, creating the supersonic environment necessary to operate the engine. The scramjet successfully propelled the cruiser more than 230 nautical miles in approximately six minutes, streaking through the sky from Mach 4.8 to Mach 5.1 while climbing in altitude.  The engine ran full duration, depleting all fuel as planned. It was the longest of the four X-51A test flights and the longest air-breathing hypersonic flight ever. Early indications show the propulsion system accomplished all objectives.
