ABSTRACT:
A turbine having a radial inlet to the turbine wheel is provided with a multi-stage stator wherein the vanes of its separate stages are fixed at different angles of incidence. The stator is mounted for movement so that each of its stages may be positioned in alignment with said opening. The vanes of one stage of the stator are inclined relative to the inlet to produce forward rotation of the turbine wheel while those of another stage are inclined oppositely to produce reverse rotation thereof. The system includes means for positioning the stator so that the vanes of two adjacent stages thereof are located in partial alignment with the inlet opening so as to regulate the power output of the turbine to a neutral state.
