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.

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

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 ...

On January 14, GE Aerospace and Lockheed Martin revealed the results of a new ...
