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

A series of tests have demonstrated the viability of a liquid-fueled rotating detonation ramjet for hypersonic missiles, ...

The compact, liquid-fuelled ramjet engine uses a novel combustion technology called rotating detonation that offers ...

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 ...

China has tested a powerful engine that can carry weapons at remarkable speeds through both air and water. The novel engine achieved 90% efficiency in laboratory tests, which were conducted in ...

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.

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) ...
