WASHINGTON, July 2 (Reuters) - The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times the mass of our sun that exhausts its ...

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 ...

Chinese scientists have once again innovated a new technology—and not just any technology, but an extraordinary new engine that could improve rotating detonation engines. It could have profound ...

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 ...

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 ...

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) ...

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, ...

GE and Lockheed ground tested a new air-breathing hypersonic jet engine capable of powering missiles to speeds well in excess of Mach 5 in a smaller, cheaper, lighter, and more efficient package than ...
