  1. 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 …

  2. 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 …

  3. Jet engine - Ramjets, Supersonic Combustion | Britannica

    Oct 1, 2025 · This combination of circumstances gives rise to the ramjet, a jet engine in which the pressure increase is attributable only to the ram effect of the high flight speed; no turbomachinery is …

  4. How Ramjets Work - HowStuffWorks

    Apr 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 …

  5. 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), …

  6. Evolution of Ramjet Engines: Past and Present

    Mar 27, 2025 · 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 …

    Nov 20, 2025 · 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 …

  8. Like cars, rockets evolve: Navy’s ramjet test proves game ... - NAVAIR

    May 7, 2025 · Naval Air Warfare Center Weapons Division successfully air-launched a Solid Fuel Integral Rocket Ramjet (SFIRR) from an unmanned vehicle for the first time, one step toward …

  9. In a 1st in world, Army set to deploy ramjet-powered shells for 155mm ...

    3 days ago · India News: NEW DELHI: The Indian Army is on the cusp of becoming the world’s first armed force to operationally deploy ramjet-powered artillery shells for its 15.

  10. Ramjet - SKYbrary Aviation Safety

    A ramjet is a variant of an air breathing jet engine that does not include a rotary compressor; rather, it uses the engine's forward motion to compress the incoming air. A ramjet cannot function at zero …
