  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. 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 …

  3. Ramjet / Scramjet Thrust - NASA

    May 13, 2021 · 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 …

  4. What Is a Ramjet and How Does It Work? - Engineer Fix

    Nov 6, 2025 · A ramjet is a type of air-breathing jet engine that uses the vehicle’s high-speed forward motion to compress incoming air, rather than relying on mechanical compressors or turbines.

  5. 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.

  6. 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), …

  7. Breakthroughs in Testing Solid-Fuel Ramjets Advance Research

    Jan 28, 2026 · A solid-fuel ramjet is an air-breathing engine that uses solid fuel instead of liquid fuel, offering high energy density and mechanically simple propulsion by burning fuel with oxygen from the...

  8. 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 …

  9. Ramjet Overview Original idea predates turbojet 1913: French patent (Lorin) 1930’s and early 1940’s: development work in Soviet Union and Germany, including engine flight tests late 1940’s: first flight …

  10. DRDO tests Ramjet technology: What is it and why is it critical for ...

    Feb 3, 2026 · A ramjet is a type of air-breathing jet engine that uses the missile’s forward speed to compress incoming air, rather than relying on complex rotating parts like conventional jet engines.
