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 ...

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 ...

When is an empty tube not an empty tube? When it's a ramjet that uses rotating detonation technology to propel aircraft at hypersonic speeds. A case in point is Venus Aerospace's new Venus Detonation ...

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 ...

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 ...

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) ...

A new family of engines aims to harness the power of detonation shockwaves to create ever-faster rocket engines. One of these engines—known as a rotating detonation engine (RDE)—has shown some ...

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, ...

A new type of rocket engine, one that could power a plane from Los Angeles to Tokyo in just two hours, has eluded scientists for decades. Houston’s Venus Aerospace says it recently solved the puzzle.

Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A team at Tsinghua University in Beijing created a new design known as the ...

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 ...
