Abstract
An aircraft powerplant assembly includes a compressor rotor, a compressor vane structure, a diffuser structure, a combustor and an air system. The compressor rotor includes a rotor stage and a rotor hub. The rotor hub includes a hub wall connected to a rotor base. An outer surface of the hub wall forms an inner peripheral boundary of a first section of an air passage. The compressor vane structure is radially outboard of the hub wall. The diffuser structure includes a diffuser nozzle and a diffuser plenum. The combustor is disposed in the diffuser plenum. The air system includes an air circuit and a heat exchanger. The air system is configured to bleed compressed air from the diffuser plenum through a circuit inlet, cool the compressed air with the heat exchanger to provide cooled air, and direct the cooled air into the air passage through a circuit outlet.
