  • 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
  • Ramjet | Supersonic, Jet Engines, Propulsion | Britannica
    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 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
  • 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
