{{expand section|date=August 2019}}

[[Gas turbine]] engines— mostly used for aircraft— are usually separated into the following categories:
* [[Turbojet]], gasses travel through a propelling nozzle
* [[Turbofan]], gasses travel through a ducted fan
* [[Turboprop]], gasses travel through an unducted propeller, usually with variable pitch
* [[Turboshaft]], a gas turbine optimised for producing mechanical torque instead of thrust
