The demon of engine knock is something an owner of a traditional high-performance Pontiac knows all too well. An engine designed when 102-octane high test was at almost every fuel station in the ...

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 dirty word around hot rods. Nobody likes to talk about it because when it happens, it usually means some lapse of attention during engine or vehicle assembly has occurred. By the time ...

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 ...

Astrobotic Technology says it has fired a rotating detonation rocket engine at 4,000 pounds of thrust, a milestone that puts the Pittsburgh-based lunar logistics company at the leading edge of an ...

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 ...

WEST LAFAYETTE, Ind. – Researchers at Purdue University have developed new combustion technology that can shrink the size of engines and eliminates the need for them to be round in shape. The novel ...

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 ...
