ABSTRACT:
Turning, or pre-swirl, vanes are housed in stationary walled annular passages located in juxtaposition with coolant gas supply slots through which coolant gas, usually air, enters the rotor structure of a rotor rim-ventilated generator. Coolant gas flow admitted through the annular passages is turned in the direction of the rotor rotation and provided with an initial tangential velocity by the turning vanes.
