ABSTRACT:
An aerodynamically efficient flow transfer device having a means to transfer flow from a static element to a rotor element such that the end of the exit flow is substantially parallel to an exit plane that is perpendicular to the axis of rotation of the rotor and substantially tangential to the operational rotational direction of the rotor. The preferred embodiment provides a cooling air flow transfer apparatus, between a stationary compressor and turbine rotor, having an inducer which includes cooling air flow holes or passages that are acutely angled in a tangential manner to the rotational direction of the rotor. The passages include a cylindrical section leading to a downstream flared outlet in the form of an open channel that has a back wall with a portion that curves to be parallel to the exit plane of the inducer at the channel's end.
