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 ...

Researchers from Tohoku University theoretically established a connection between ignition and deflagration in a combustion system, opening up new possibilities for stable, effective combustion engine ...

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 ...

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 ...

NASA’s Marshall Space Flight Center in Huntsville, Alabama, recorded ignition of a full-scale Rotating Detonation Rocket Engine combustor, which was fired for a record 251 seconds and achieved more ...

Liquid-fuelled rocket engine design has largely followed a simple template since the development of the German V-2 rocket in the middle of World War 2. Propellant and oxidizer are mixed in a ...
