Ramjet engines provide a simple and lightweight propulsion system designed for supersonic flight.They draw in large amounts of air through the engine inlet using the forward motion of the aircraft.

Some ramjet and scramjet engines can even break the sound barrier, allowing aircraft to move at a hypersonic speed thanks to the engine's unique architecture. Let's look at the differences between ...

Atlanta company Hermeus has its sights set on Mach 4 next year, to beat the Mach 3.3 benchmark set by the SR-71 Blackbird way back in 1976. Watch its Chimera hybrid engine nailing the switch ...

GE Aerospace announced in December it has demonstrated what is believed to be a world-first hypersonic dual-mode ramjet rig test with rotating detonation combustion in a supersonic flow stream ...

The Hypersonic Dual-Mode Ramjet test, believed to be the first of its kind, exploited rotating detonation combustion technology. General Electric Aerospace announced a successful demonstration of ...

Telemetry revealed the boron ramjet was achieving a specific impulse of over 4,700 Newton-seconds per kilogram. That's one-third better than even SpaceX's latest Raptor rocket engine.

In addition, a Boeing and Norwegian-based Nammo team recently set a new record for the longest indirect fire test of a ramjet-powered 155mm artillery projectile from the Army’s Extended Range ...
