There have been published papers by the Air Force Research Lab and NASA on rotating detonation engines having 10% or more efficiency gains. A rotating detonation engine (RDE) uses a form of pressure ...

Rotating detonation engine could be up to 25% more efficient than traditional jet engines. This could make airplanes and missile faster or with longer range. Smaller weapons could reach the same ...

GE Aerospace says it successfully demonstrated an advanced jet propulsion concept that involves a dual-mode ramjet design utilizing rotating detonation combustion. This could offer a pathway to the ...

The US Navy relies heavily on gas turbine engines to power both aircraft and ships, spending about $2 billion (with a “b”… or about one tenth of NASA’s entire budget last year) every year on fuel for ...

COLORADO SPRINGS—Long-running U.S. interest in the potential application of pressure-gain combustion to high-speed propulsion is stepping up to a new level with the award of a U.S. Air Force Research ...

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 ...
