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 ...

American researchers are finally getting a real-time view inside one of the most unforgiving propulsion systems in service, ...

The rotating detonation ramjet engine provides a more compact, lightweight design than standard engine designs, and uses a continuous, self-sustaining detonation wave. GE Aerospace and Lockheed Martin ...

A Chinese aerospace firm tested a detonation ramjet engine for the first time, aiming to power aircraft capable of flying passengers from Beijing to New York in just two hours. The Jindouyun, or ...

GE Aerospace reported it successfully demonstrated a hypersonic dual-mode ramjet it said could make possible “high-speed flight and longer range” for multi-mission aircraft. The developer also noted ...

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.

For years, the United States has trailed behind Russia and China in hypersonic weapons. A new engine prototype by Lockheed Martin and General Electric could help it catch up.

Rotating Detonation Engines (RDE) have been flown by Venus Aerospace. They use continuous detonation waves for propulsion and provide 15% efficiency gains (in specific impulse or fuel consumption) ...
