GE Aerospace and Lockheed Martin complete hypersonic engine tests

GE Aerospace (NYSE: GE) and Lockheed Martin (NYSE: LMT) completed engine tests demonstrating a liquid-fueled rotating detonation ramjet for hypersonic missiles, according to a company statement.

The tests represent the first initiative under a broader joint technology development arrangement between the companies. The rotating detonation ramjet uses detonation waves instead of traditional combustion methods found in current ramjet engines.

The propulsion system generates thrust for supersonic and hypersonic speeds while maintaining a smaller engine size and weight compared to conventional ramjet options. The compact design allows for increased fuel or payload capacity and enables ignition at lower speeds, requiring smaller boosters for ramjet startup.

"The testing on the rotating detonation ramjet and inlet exceeded expectations," said Mark Rettig, vice president and general manager of Edison Works Advanced Programs at GE Aerospace.

Randy Crites, vice president and general manager at Lockheed Martin Advanced Programs, stated the demonstration followed two years of internal investment. "This compact ramjet applies Lockheed Martin's expertise in ramjet inlets and offers extended range at extreme speeds," Crites said.

The technology aims to enable missiles to fly at hypersonic speeds with improved fuel efficiency and extended range while reducing production costs. The system targets engagement of high-value, time-sensitive targets through enhanced propulsion capabilities.

Both companies indicated plans to continue developing the air-breathing hypersonic propulsion technology under their collaboration agreement.
