Jet Propulsion/Turbines

A turbine produces mechanical work from the pressure or kinetic enrgy of a moving fluid. They differ from reciprocating motors in that the fluid flows through continuously.

Turbines like compressors can be axial or radial.

Applications

edit

The earliest water turbines were water wheels.

These extract mechanical work from water pressure.

Water turbines

Commonly known as windmill extract work from the wind.

wind turbine

These extract mechanical work from steam.

steam turbine

Used in most gas turbines and steam turbines

Used in turbochargers and small gas turbines.
