Aerojet Rocketdyne Successfully Tests Hypersonic DMRJ Engine

Aerojet Rocketdyne successfully tested a new dual-mode ramjet/scramjet (DMRJ) engine. When combined with a gas turbine engine as part of a turbine-based combined cycle propulsion (TBCC) system, this engine may provide the capability to propel a vehicle from a standstill into the hypersonic flight regime of Mach 5 or higher and back again.

“Developing hypersonic capabilities has recently been cited by Department of Defense officials as the ‘highest technical priority’ for our nation,” said Aerojet Rocketdyne CEO and President Eileen Drake. “Aerojet Rocketdyne is well positioned to support this call to action as we have been developing hypersonic propulsion technologies for more than 30 years. Our scramjet engine powered the record-setting test flights of the X-51A WaveRider, and we have accelerated our development efforts since then. That progress, when combined with the advances we’ve made in additive manufacturing has enabled this next generation of hypersonic propulsion systems.”

The series of tests were conducted as part of an ongoing collaboration with the Defense Advanced Research Projects Agency, NASA and the United States Air Force to develop hypersonic propulsion technologies. These tests also helped validate an advanced analytical tool set developed by Aerojet Rocketdyne that enables precise simulation of complex DMRJ flow fields across a broad scale of applications.
