  1. jet engine(noun)

    a gas turbine produces a stream of hot gas that propels a jet plane by reaction propulsion

Wiktionary

  1. jet engine(Noun)

    an engine that obtains thrust by taking in air at the front, using it to burn fuel, then ejecting the hot combustion products at the rear through a propulsive nozzle

  2. jet engine(Noun)

    any engine propelled by expelling a high speed fluid jet (jet propulsion), such as a rocket, turbojet, turbofan, ramjet etc.

Freebase

  1. Jet engine

    A jet engine is a reaction engine that discharges a fast moving jet which generates thrust by jet propulsion in accordance with Newton's laws of motion. This broad definition of jet engines includes turbojets, turbofans, rockets, ramjets, and pulse jets. In general, most jet engines are internal combustion engines but non-combusting forms also exist. In common parlance, the term jet engine loosely refers to an internal combustion airbreathing jet engine. These typically consist of an engine with a rotary air compressor powered by a turbine, with the leftover power providing thrust via a propelling nozzle. These types of jet engines are primarily used by jet aircraft for long-distance travel. Early jet aircraft used turbojet engines which were relatively inefficient for subsonic flight. Modern subsonic jet aircraft usually use high-bypass turbofan engines which offer high speed with fuel efficiency comparable to piston and propeller aeroengines.
