Abstract
The compressor discharge air that normally leaks from the high pressure compressor hub and a portion of the compressor discharge air that is utilized for component cooling, is re-routed to by-pass the engine's TOBI to flow into a manifold defined by the stator support structure and a foot of the first turbine vane to the inner diameter platform of the first turbine vane of the high pressure turbine section to cool the aft end thereof before being discharged into the engine's main gaseous stream.
