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.

When is an empty tube not an empty tube? When it's a ramjet that uses rotating detonation technology to propel aircraft at hypersonic speeds. A case in point is Venus Aerospace's new Venus ...

Song said the ramjet engine could more than triple the range of Chinese BVRAAMs. The PL-12’s range, for example, could increase from 62 miles to over nearly 200 miles.

Boeing and defense company Nammo partnering with the US Army have set a new range record during an indirect fire test of a ramjet-powered artillery shell when a Ramjet 155-mm round was fired from ...

Hermeus demonstrated that its engine can transition from turbojet—like what’s used in passenger aircraft—to ramjet, a much more powerful engine technology. Hermeus, a startup building a ...

The US Army highlighted an ongoing program to upgrade the range of its Stinger missiles. The program, Red Wasp, has been applying solid fuel ramjet technology to increase reach. Stingers have seen ...

U.S. Army researchers have revealed an experimental air defense interceptor powered by a dual-cycle, rocket-ramjet propulsion system. The Red Wasp program is evaluating how to package a solid fuel ...

Ramjet took the top spot on the "Japan Road to the Kentucky Derby" leaderboard with a victory in the Feb. 18 Hyacinth Stakes at Tokyo Racecourse while previous leader, Forever Young , prepares for ...

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.

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 ...
