  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. Jet engine - Ramjets, Supersonic Combustion | Britannica

    Mar 17, 2026 · 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 …

  5. 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.

  6. Breakthroughs in Testing Solid-Fuel Ramjets Advance Research

    Jan 29, 2026 · A solid-fuel ramjet is an air-breathing engine that uses solid fuel rather than liquid, offering high energy density and mechanically simple propulsion by burning the fuel with oxygen from …

  7. 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 …
