Aerojet Rocketdyne’s Advanced Scramjet Engine Powers Successful Hypersonic Vehicle Flight

HUNTSVILLE, Ala., April 06, 2022 (Aerojet Rocketdyne PR) — An advanced Aerojet Rocketdyne scramjet engine powered the successful flight test of the Hypersonic Air-breathing Weapon Concept (HAWC), in a joint effort with the Defense Advanced Research Projects Agency (DARPA), Air Force Research Laboratory (AFRL) and Lockheed Martin.

The goal of the DARPA / Lockheed Martin HAWC program is to develop and demonstrate critical technologies to enable an effective and affordable air-launched hypersonic cruise missile system.

“Aerojet Rocketdyne is well-positioned to support our nation’s hypersonic development and production,” said Eileen P. Drake, Aerojet Rocketdyne CEO and president. “By applying decades of advanced research and development, together with engineering know-how and innovative manufacturing and materials, our products optimize performance while dramatically reducing costs and development time.”

Through the use of additive manufacturing, Aerojet Rocketdyne is using 95% fewer parts in its scramjets than it used for the history-making scramjet engine that powered the United States Air Force X-51A Waverider to sustained hypersonic speed. Aerojet Rocketdyne has continued to improve the aerothermal performance, affordability, scalability and rapid manufacturability of scramjet engines to meet emerging needs for hypersonic missile and aircraft applications.

Along with innovative scramjets, Aerojet Rocketdyne manufactures a wide range of products to support hypersonics, including solid rocket motor boosters, warheads and missile defense technologies.
