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

GE Aerospace and Lockheed Martin complete missile-scale rotating detonation ramjet tests, targeting longer-range and more ...

Detonation combustion achieves near-constant-volume burning, drastically reducing entropy generation and wasting less energy as heat compared to traditional deflagration propulsion. Its supersonic ...

Researchers have theoretically linked ignition and deflagration in a combustion system, unlocking new configurations for stable, efficient combustion engines due to the possible existence of any ...

The race to field reusable hypersonic aircraft got a whole lot hotter last month, with GE Aerospace announcing a breakthrough in high-speed jet engine design that could potentially allow conventional ...

The rapid, violent detonation of a high explosive (HE) generates supersonic shock waves that transfer energy by moving mass. According to Livermore physicist John Molitoris, trying to gather data on ...
