A jet engine is any engine that can propel an aircraft of some kind via rearward expulsion of a jet of fluid, typically a hot exhaust gas that the engine generates by drawing in fuel from the ...

In science fiction stories about contact with extraterrestrial civilisations, there is a problem: What kind of propulsion system could make it possible to bridge the enormous distances between the ...

The Solid Fuel Ramjet (SFRJ) and the Hypersonic Dual-Mode Ramjet (DMRJ) are seeing rapid success as the U.S. hikes spending and development of hypersonic weapons. GE Aerospace has shed more light on ...

Theoretical tests say that this beast of an engine should be capable of hypersonic flight over Mach 5+ (3,836 mph / 6,174 km/h), at considerably higher efficiency than other detonation engines – and ...

GE Aerospace is advancing hypersonic flight with plans to scale up its dual-mode ramjet technology in 2025. To create a full propulsion system, engineers will improve sophisticated controls and use ...

TL;DR: A hypersonic dual-mode ramjet engine is a high-speed air-breathing jet engine capable of operating efficiently at both lower and extremely high Mach speeds by utilizing dual combustion modes.

The U.S. Navy successfully air-launched a Solid Fuel Integral Rocket Ramjet (SFIRR) from an unmanned vehicle for the first time, one step toward modernizing missile technology. The effort by Naval Air ...
