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).

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.

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.

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.

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?

2 天之前 · A ramjet engine is a type of air-breathing engine that is commonly used in aircraft. It operates by taking in incoming air and subsequently releasing hot gases, which in turn produce forward propulsion or thrust. As shown in Figure 1 below, …

2025年2月17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.

2025年2月20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 in Missile • Early ramjet application (1950’s, US Navy SAM) • Actually layout more complicated than simple schematic

In this article we summarize programs to develop surface-launched and air-launched subsonic combus- tion ramjets and scramjets. Table 1 shows the evolu- tionary history of all of the ramjet and scramjet engine and vehicle concepts and systems included in these discussions.
