Ramjet - Wikipedia
WEBA ramjet is a form of airbreathing jet engine that requires forward motion of the engine to provide air for combustion. Ramjets work most efficiently at supersonic speeds around Mach 3 (2,300 mph; 3,700 km/h) and can operate up to Mach 6 (4,600 mph; 7,400 km/h).
Ramjet / Scramjet Thrust - NASA
WEBMay 13, 2021 · A ramjet engine provides a simple, light propulsion system for high speed flight. Likewise, the supersonic combustion ramjet, or scramjet , provides high thrust and low weight for hypersonic flight speeds. Unlike a turbojet engine, ramjets and scramjets have no moving parts, only an inlet, a combustor that consists of a fuel injector and a ...
How Ramjets Work | HowStuffWorks
WEBApr 16, 2024 · A ramjet is a type of air-breathing jet engine that operates on the principle of compressing incoming air without the need for rotating parts. It relies on the high-speed forward motion of the aircraft to compress air, making it suitable for supersonic and hypersonic flight.
