| turbofan |
Basically a turbojet engine with extra turbine
stages driving a large diameter fan which generates most of the thrust;
most of the airflow bypasses the engine core |
| turbojet |
Most basic form of gas turbine; consisting of
compressor, combustion chamber and turbine; most energy remains as gas
which is expended through a propulsive nozzle at high velocity |
| turboprop |
Similar to turbofan, but power is geared-down to
drive a propellor |
| turboshaft |
Gas turbine which powers a high-speed shaft;
usually in a helicopter |
