Turbojet
A simple type of jet engine that compresses air, mixes it with fuel, ignites it, and expels the hot gases to create thrust. All the air goes through the engine's core.
TECHNICAL DEFINITION
The simplest form of gas turbine engine, where all incoming air passes through the compressor, combustion chamber, and turbine before being expelled as a high-velocity exhaust jet to generate thrust, typically less fuel-efficient than turbofans but capable of high speeds.
BACKGROUND
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which adds kinetic energy to the air passing through it by burning fuel, and a ducted fan powered by energy from the gas turbine to force air rearwards. Whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of the air entering the nacelle bypasses these components. A turbofan can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust.
