Craig Nordeen (Air Force Research Lab, Pratt & Whitney) gives a lesson from three years ago on detonation engines. He describes the history and how they work and why they are more efficient. The work ...

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 ...

Essentially, it's a rotating detonation engine in which the detonation wave is stabilized within a high-speed rotor. A precisely shaped flow channel within the rotor compresses the air-fuel mixture to ...

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 ...

A startup high-speed flight company from Houston, Texas, has successfully tested its Rotating Detonation Rocket Engine (RDRE) ultimately aimed at allowing travel at four to six times the speed of ...

Detonation is a supersonic combustion wave, characterized by a shock wave driven by the energy release from closely coupled chemical reactions. It is a typical form of pressure gain combustion, ...

Rotating Detonation Engines (RDE) have been flown by Venus Aerospace. They use continuous detonation waves for propulsion and provide 15% efficiency gains (in specific impulse or fuel consumption) ...

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 ...

China says it has taken a big step forward in hypersonic engine technology. This could change the future of high-speed flight and military power. The announcement has caught global attention, ...

Add Yahoo as a preferred source to see more of our stories on Google. Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A ...
