Powered Flight - Methods of Propulsion - Jet Propulsion - Jet Aircraft
... Airbreathing jet engines provide thrust by taking in air, compressing the air, injecting fuel into the hot compressed air mixture in a combustion chamber, the resulting ... The reaction against this acceleration provides the engine thrust ... Jet engines can provide much higher thrust than propellers, and are naturally efficient at higher altitudes, being able to operate above 40,000 ft (12,000 m) ...
Supersonic Transports - Challenges of Supersonic Passenger Flight - Engines
... Jet engine design shifts significantly between supersonic and subsonic aircraft ... Jet engines, as a class, can supply increased fuel efficiency at supersonic speeds, even though their specific fuel consumption is greater at higher speeds ... When Concorde was being designed by Aérospatiale–BAC, high bypass jet engines ("turbofan" engines) had not yet been deployed on subsonic aircraft ...

... heat and pressure of the exhaust gas to accelerate the jet to high speed so as to efficiently propel the vehicle ... For air-breathing engines, if the fully expanded jet has a higher speed than the aircraft's airspeed, then there is a net rearward momentum gain to the air and there will be a forward ... Simple convergent nozzles are used on many jet engines ...

Space Shuttle Design Process - Shuttle Design Debate
... Both booster and orbiter would have rocket engines plus jet engines for use within the atmosphere, plus separate fuel and control systems for each ... Earlier designs assumed the winged orbiter would also have jet engines to assist maneuvering in the atmosphere after reentering ... Omitting the jet engines and their fuel would reduce complexity and increase payload ...

Famous quotes containing the words engines and/or jet:

    America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.
    Thomas McGuane (b. 1939)

    Gimme the Plaza, the jet and $150 million, too.
