impulse turbine

A type of turbine in which the stator vane and rotor blades are arranged in such a way that the pressure drop occurs in the converging nozzle guide vane passages along with a corresponding increase in velocity while the blades form straight ducts. The turbine rotor is then turned by the impulse as gases impinge on the blades—hence, the nomenclature.
Variation of pressure and velocity through an impulse turbine.
