A windage shield system is provided. The system includes an annular cavity having an inlet end and an outlet end. The annular cavity is configured to direct a flow of cooling fluid from the inlet end to the outlet end. The system also includes a source of a flow of cooling fluid coupled in flow communication with the annular cavity. The annular cavity is bounded by a stationary component and a rotating component, and the rotating component introduces heat into the annular cavity by windage effects. The system also includes a cooling channel coupled in flow communication with the outlet end, and a first windage shield extending from the outlet end towards the inlet end within the annular cavity.

Windage shield system and method of suppressing resonant acoustic noise

A nozzle vane includes a row of trailing edge apertures and cooperating inboard slots joined in flow communication with a mid-chord cavity. An outboard slot is spaced outwardly from a respective last one of the inboard slots, and outboard of a respective last one of the trailing edge apertures. The outboard slot extends behind a braze joint between the vane and a supporting band and is effective for backside cooling thereof.
