A rotary machine which extracts mechanical shaft power from the working fluid, gas or liquid, using rotor vanes. Steam turbines often propel ships and power stations. Gas turbines are also used.

The energy, originally in the form of head or pressure energy, is converted to velocity energy by passing through a system of stationary and moving blades in the turbine.
