  2. Components of jet engines - Wikipedia

    en.wikipedia.org/wiki/Components_of_jet_engines

    Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...

  3. Turbofan - Wikipedia

    en.wikipedia.org/wiki/Turbofan

    Consequently, an engine sized to propel an aircraft at high subsonic flight speed (e.g., Mach 0.83) generates a relatively high thrust at low flight speed, thus enhancing runway performance. Low specific thrust engines tend to have a high bypass ratio, but this is also a function of the temperature of the turbine system.

  4. Jet engine - Wikipedia

    en.wikipedia.org/wiki/Jet_engine

    All of the above considerations are basic to the engine running on its own and, at the same time, doing nothing useful, i.e. it is not moving an aircraft or supplying energy for the aircraft's electrical, hydraulic and air systems. In the aircraft the engine gives away some of its thrust-producing potential, or fuel, to power these systems.

  5. Gas turbine engine thrust - Wikipedia

    en.wikipedia.org/wiki/Gas_turbine_engine_thrust

    The engine thrust acts along the engine centreline. The aircraft "holds" the engine on the outer casing of the engine at some distance from the engine centreline (at the engine mounts). This arrangement causes the engine casing to bend (known as backbone bending) and the round rotor casings to distort (ovalization).

  6. Pulsejet - Wikipedia

    en.wikipedia.org/wiki/Pulsejet

    Diagram of a valved pulsejet. 1 - Air enters through valve and is mixed with fuel. 2 - The mixture is ignited, expands, closes the valve and exits through the tailpipe, creating thrust.3 - Low pressure in the engine opens the valve and draws in air.

  7. Turboprop - Wikipedia

    en.wikipedia.org/wiki/Turboprop

    Schematic diagram showing the operation of a turboprop engine Propulsive efficiency for different engine types and Mach numbers. Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine expansion.

  8. Pratt & Whitney JT8D - Wikipedia

    en.wikipedia.org/wiki/Pratt_&_Whitney_JT8D

    It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 Intruder and A-4 Skyhawk attack aircraft. Eight models comprise the JT8D standard engine family, covering the thrust range from 12,250 to 17,400 pounds-force (54 to 77 kN), and power the 727, 737-100/200, and DC-9.

  9. Pratt & Whitney PW4000 - Wikipedia

    en.wikipedia.org/wiki/Pratt_&_Whitney_PW4000

    X describes the aircraft manufacturer for which the engine is approved. A "0" stands for Boeing; "1" for Airbus; and "4" for the McDonnell Douglas MD-11. YZ denotes the certified thrust in US pounds (lbf) in pro-mile fraction. Example: A PW4090 identifies a PW4000 series engine certified for Boeing (777-200ER) and has a certified thrust of ...
