I recently got asked about what "pinging" is, and what the difference is between pre-ignition and detonation, what causes it, and why it is bad for an engine. Basically, both pre-ignition and ...

(RTTNews) - RTX Corp. (RTX), an aerospace and defense company, announced on Wednesday that its unit Raytheon has bagged a contract from the Defense Advanced Research Projects Agency or DARPA to ...

A Florida team working with the US Air Force claims that it's built and tested an experimental model of a rotating detonation rocket engine, which uses spinning explosions inside a ring channel to ...

Dear Doctor: My 2015 Ford Fusion with the 2.0-liter turbocharged engine is at the local Ford dealership for a new engine, due to a piston breaking from a low speed pre-ignition incident. Luckily, the ...

Engines that convert chemical energy from fuel into kinetic energy via explosive detonation, rather than slower deflagration combustion as seen in typical internal combustion engines. Categories ...

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 ...

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 ...

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 ...

A new rotating detonation engine could revolutionize rocket launches—if it can be made stable enough. That’s a big “if,” and one that researchers are hoping to explore using a new mathematical model ...

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 ...
