Abstract
A segmented seal plate supporting a brush seal mounted in the space between the compressor and turbine and bearing against the shaft of a microturbine engine form a barrier in this cavity and serves to control flow in this space. A plurality of circumferentially spaced discretely sized holes in the seal plate judiciously located above the brush seal bearing against the shaft interconnecting the back-to-back mounted compressor/turbine controls the amount of cooling air so that the combination of the brush seal, segmented plate and discretely sized holes controls the leakage from the compressor of each engine of a given model and controls cooling flow to the turbine for reducing efficiency scatter from engine to engine.
