    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. Propelling nozzle - Wikipedia

    en.wikipedia.org/wiki/Propelling_nozzle

    The increased thrust from the C-D nozzle (2,000 lb, 910 kg at sea-level take-off) on this engine raised the speed from Mach 1.6 to almost 2.0 enabling the Air Force to set a world's speed record of 1,207.6 mph (1,943.4 km/h) which was just below Mach 2 for the temperature on that day. The true worth of the C-D nozzle was not realised on the F ...

  4. Turbojet - Wikipedia

    en.wikipedia.org/wiki/Turbojet

    The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle . The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor).

  5. Air turborocket - Wikipedia

    en.wikipedia.org/wiki/Air_turborocket

    The engine would start out operating as a turbojet during takeoff and while climbing to altitude. Upon reaching high subsonic speed, the portion of the engine downstream of the turbojet would be used as an afterburner to accelerate the plane above the speed of sound. [3] At lower speeds, air passes through an inlet and is then compressed by an ...

  6. Jet engine - Wikipedia

    en.wikipedia.org/wiki/Jet_engine

    Jet engine during take-off showing visible hot exhaust (Germanwings Airbus A319) A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion.

  7. Pratt & Whitney JT8D - Wikipedia

    en.wikipedia.org/wiki/Pratt_&_Whitney_JT8D

    The JT8D is an axial-flow front turbofan engine incorporating a two-spool design. There are two coaxially-mounted independent rotating assemblies: one rotating assembly for the low pressure compressor (LPC) which consists of the first six stages (i.e. six pairs of rotating and stator blades, including the first two stages which are for the bypass turbofan), driven by the second (downstream ...

  8. Jet engine performance - Wikipedia

    en.wikipedia.org/wiki/Jet_engine_performance

    The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.

  9. Air-start system - Wikipedia

    en.wikipedia.org/wiki/Air-start_system

    Compressed air is sent to the ATS turbine from the aircraft auxiliary power unit ( bleed air from the gas generator or from a free-turbine load compressor, eg PW901 APU), from an already-running engine (bleed air) on a multi-engined aircraft or, for early jet aircraft, from an air compressor mounted on ground support equipment.
