Ramjet - Wikipedia
A 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
2021年5月13日 · 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.
How Ramjets Work - HowStuffWorks
2024年4月16日 · 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.
Ramjet Propulsion - NASA
2021年5月13日 · In a ramjet, the high pressure is produced by "ramming" external air into the combustor using the forward speed of the vehicle. The external air that is brought into the propulsion system becomes the working fluid, much like a turbojet engine.

2024年10月14日 · ramjet, air-breathing jet engine that operates with no major moving parts. It relies on the craft’s forward motion to draw in air and on a specially shaped intake passage to compress the air for combustion.
Ramjet Thrust - NASA
A ramjet engine provides a simple, light propulsion system for high speed flight. Unlike a turbojet engine, a ramjet has no moving parts, only an inlet, a combustor that consists of a fuel injector and a flame holder, and a nozzle. How does a ramjet work?
Understanding Ramjet Propulsion Basics for Aviation Advances
2024年4月23日 · Ramjet propulsion is a type of air-breathing propulsion system that operates by utilizing the forward motion of the vehicle to compress incoming air, making it an efficient choice for high-speed aircraft.
Jet engine - Ramjets, Supersonic Combustion | Britannica
2024年10月18日 · Ramjets (see Figure 7) are lightweight and simple power plants, making them ideal candidates for supersonic flight vehicles that are launched from other flight vehicles at extremely high speed.
What's the difference between a scramjet and a ramjet engine?
In a ramjet, the combustion chamber - where the air is mixed with fuel and ignited - only works at subsonic speeds. So the intake slows the air down, releasing some of its energy as a shock wave, but this reduces fuel efficiency. The scramjet is an innovation on the ramjet in which the combustion chamber is specially designed to operate with ...
Scramjets vs. Ramjets: What's the Difference? - AeroXplorer
2022年10月26日 · The ramjet is a jet engine without a compressor or a turbine. It is essentially a tube through which air enters purely as a result of the plane's forward motion. At the inlet, the air hits a diffuser to create high static pressure for combustion and is slowed to subsonic speeds.
