摘要： A compressor housing for an air cycle machine is provided. The compressor housing includes a body having a compressor volute configured to provide centrifugal compression in the air cycle machine. A mating surface is integrally formed with the body. The mating surface includes a plurality of substantially equally angularly spaced bosses. The bosses include a first boss type at a first radial distance and configured to receive a threaded fastener coupled to a turbine nozzle of the air cycle machine. The bosses also include a second boss type at a second radial distance configured to secure a seal plate of the air cycle machine. The second radial distance is less than the first radial distance. A ratio of a number of the bosses of the first boss type to the second boss type is 17 to 2.

摘要： A hydrodynamic thrust bearing has an annular plate, a plurality of bearing foils, and a plurality of bumper foils. The annular plate has a first face and a second face opposite the first face. The bearing foils have an arcuate shape and are joined to the first face of the annular plate. The bumper foils have an arcuate and corrugated shape and are joined to the second face of the annular plate. A method of making a hydrodynamic thrust bearing includes joining the bearing and bumper foils to the annular plate with integrally-formed spacers in which each bumper foil corresponds to a bearing foil.

摘要： A compressor rotor compresses air and delivers the compressed air to a downstream inlet and across a turbine rotor. A shaft rotates with the turbine rotor and the compressor rotor. The shaft is hollow with an inner bore and an outer periphery. At least one journal bearing supports a portion of the shaft, and has an inner bore spaced from the outer periphery of the shaft. A cooling air path is provided between the shaft outer periphery and the bearing inner periphery, and along a length of the bearing to at least one connection hole. The connection hole provides cooling air from an outer periphery of the shaft to the inner bore of the shaft. In a separate feature, a shaft for use in an air supply machine includes a hollow interior, with such a connection hole.

摘要： A system and method onboard an aircraft includes a ram air temperature sensor, a bleed air temperature sensor, a valve, and a controller. The ram air temperature sensor is positioned to sense a ram air temperature of a ram air flow. The bleed air temperature sensor is positioned to sense a bleed air temperature of a bleed air flow, wherein the bleed air flow is cooled by a heat exchanger using the ram air flow. The valve is configured to control the bleed air flow upstream of the heat exchanger. The controller is configured to determine a bleed air threshold based on the ram air temperature, and control the valve to reduce the bleed air flow in response to the bleed air temperature reaching the bleed air threshold.
