A turbine starter (10) is provided including a housing (21) defining a fluid passageway (22) with an inlet (24) and an outlet (26). A turbine rotor (16) is supported in the housing (21) and includes blades (18) arranged in the passageway (22) between the inlet (24) and the outlet (26). The rotor (16) is movable within the passageway (22) at a speed with a fluid exiting the blade (18) toward the outlet (26). The spoiler (34) is arranged in the passageway (22) between the rotor (16) and the outlet (26). The spoiler (34) deflects the fluid exiting the blade (18) and reduces the rotor speed. Preferably, the present invention spoiler (34) is utilized to reduce the maximum speed at the no-load condition. The angle, number, position, and other characteristics of the spoiler (34) may be tailored for the particular turbine and a particular speed for which it is desirable to reduce. |
