jet engine: see jet propulsion jet propulsion, propulsion of a body by a force developed in reaction to the ejection of a high-speed jet of gas.

Jet Propulsion Engines

The four basic parts of a jet engine are the compressor, turbine , combustion chamber, and propelling nozzles.

jet engine

Any of a class of internal-combustion engines that propel aircraft by means of the rearward discharge of a jet of fluid, usually hot exhaust gases generated by burning fuel with air drawn in from the atmosphere. Jets rely on the third of Newton's laws of motion (action and reaction are equal and opposite). The first jet-powered airplane was introduced in 1939 in Germany. The jet engine, consisting of a gas-turbine system, significantly simplified propulsion and enabled substantial increases in aircraft speed, size, and operating altitudes. Modern types of jet engines include turbojets, turbofans, turboprops, turboshafts, and ramjets. See airplane. See also drag; gasoline engine; lift.
