The compact, liquid-fuelled ramjet engine uses a novel combustion technology called rotating detonation that offers significantly improved efficiency for high-speed flight at Mach 5 and beyond.

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 ...

Combining the technologies could improve efficiency enough to make hypersonic projectiles much more affordable.

GE and Lockheed ground tested a new air-breathing hypersonic jet engine capable of powering missiles to speeds well in excess ...

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 ...

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 ...

The rotating detonation rocket engine (RDRE) is the new Holy Grail of the aerospace industry. The way such a technology works promises unprecedented speeds for aircraft and spacecraft, prompting ...

Venus Aerospace's rotating detonation rocket engine (RDRE). Houston, Texas-based Venus Aerospace, a hypersonics pioneer aimed at developing reusable hypersonic flight platforms, recently achieved one ...

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 ...

There probably never was a better time for rocket engine fans to be alive. It's a time when those who have the means can go out and start building the rocket engine of their dreams, while the rest can ...
