There are four main gas turbine engines, turbo jet engines, turbofan engine, turbine propeller make hole machine and turboshaft engine. Gas turbine engine concept is as follows:

1, gas turbine, gas turbine engine is also called a belongs to the engine of heat engine, gas turbine can be known, the basic principle of the same, including gas turbine jet engines, and so on are included.

2, generally refers to gas turbine engine, is usually applied to ship (mainly military ships), vehicle (usually large size can accommodate gas turbine, such as tanks, engineering vehicles, etc.), generators, etc;

3, advancing in a different way, and turbine engine is in addition to drive the compressor, the turbine also drives the rotation axis, axis of rotation and the vehicle's transmission system, such as ship's propellers or generators.
