ABSTRACT:
An improved centripetal flow gas turbine of the type having a housing with a rotor cavity, a rotor rotatably supported in the cavity, a volute chamber around the cavity having a source of motive fluid, and a circular orifice between the volute chamber and the cavity for directing motive fluid at the rotor at a stator exit angle. The improvement resides in the provision of motive fluid manifolds coextensive with the volute chamber and in the provision of louvers connecting the manifolds with the volute chamber whereby streams of motive fluid are injected into the flow of motive fluid in the volute chamber to increase the tangential velocity component thereof and thereby alter the stator exit angle to achieve an improvement in total turbine efficiency.
