The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

Rotating detonation engines (RDEs), as opposed to oblique wave detonation engines or pulse detonation engines, use ring-shaped chambers and precisely-timed fuel injection to generate constant thrust.

Astrobotic completed a successful series of hot-fire tests of its rotating detonation rocket engine prototype, marking a key milestone for the experimental propulsion technology.

A US-based propulsion company has successfully launched and flown a new rocket powered by a unique rotating detonation engine. Although relatively small by rocket standards, the test could pave the ...

A US-based propulsion company, Venus Aerospace, said Wednesday it had completed a short flight test of its rotating detonation rocket engine at Spaceport America in New Mexico. The company’s chief ...

GE and Lockheed Martin plan to get around this by accelerating the missile using a rotating detonation engine, which uses a supersonic wave of detonating fuel that runs about inside an open-ended ...

Astrobotic put its Chakram rotating detonation rocket engine (RDRE) through its paces for the ...

On January 14, GE Aerospace and Lockheed Martin revealed the results of a new propulsion demonstration that could reshape the future of hypersonic flight. The two companies showed how a liquid-fueled ...

Rotating detonation engine could be up to 25% more efficient than traditional jet engines. This could make airplanes and missile faster or with longer range. Smaller weapons could reach the same ...

They're noisy, but your next missile or military vehicle might have an RDE (rotating detonation engine) powerplant in it. RDEs are more fuel-efficient, lighter, easier to maintain, and capable of ...

Venus Aerospace conducted its first powered flight last month, reaching Mach 0.9 with a drone. The 8-foot-long vehicle was dropped from an Aero L-29 Delfín aircraft at 12,000 feet and flew under the ...
