  • 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)
  • How Ramjets Work - HowStuffWorks
    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 Scramjet Thrust - NASA
    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
  • School of Aerospace Engineering Ramjet Overview - gatech. edu
    Ramjet in Missile • Early ramjet application (1950’s, US Navy SAM) • Actually layout more complicated than simple schematic
  • Jet engine - Ramjets, Supersonic Combustion | Britannica
    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
  • Ramjets and Scramjets - Purdue University
    A ramjet uses the ram effect, compression in an inlet, for all of the compression in an engine Hence, it has no rotor or blades; the air is compressed by the inlet (using a series of internal external shocks), ignited, and shot out the back by the nozzle
  • Ramjet Engines: Evolution and Future Potential
    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
  • Ramjet – Definition Detailed Explanation - Sentinel Mission
    What is a Ramjet? A ramjet is a type of air-breathing jet engine that operates without the use of rotating machinery, such as a turbine It is a simple yet powerful propulsion system that relies on the engine’s forward motion to compress incoming air and generate thrust
  • The Ramjet Scramjet Engine - Aviation History
    A ramjet engine A ramjet has no moving parts and achieves compression of intake air by the forward speed of the air vehicle Air entering the intake of a supersonic aircraft is slowed by aerodynamic diffusion created by the inlet and diffuser to velocities comparable to those in a turbojet augmentor
  • Ramjet Propulsion - NASA
    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
