Abstract: An air turbine starter (ATS) assembly for an aircraft has an ATS mounted to an accessory drive gearbox. The ATS includes an ATS output shaft is configured to pass from the ATS into the accessory drive gearbox. The accessory drive gearbox includes an overrunning clutch assembly configured to rotationally connect the ATS output shaft to an accessory gearbox shaft when the overrunning clutch engages the ATS output shaft such that the overrunning clutch assembly transmits rotational energy from the ATS output shaft to an accessory gearbox shaft. The overrunning clutch assembly is configured to permit the accessory gearbox shaft to rotate independent of the ATS output shaft when the overrunning shaft is disengaged from the ATS output shaft. The overrunning clutch assembly is configured to be removeable from the accessory drive gearbox as a removeable clutch cartridge.

Abstract: A pressure control system for a storage tank, including a supply of working fluid under pressure. A conduit establishes fluid communication between the supply and the storage tank. A supply regulator is provided in the conduit for maintaining a substantially constant pressure to the storage tank. A tank regulator is provided in the conduit between the supply regulator and the storage tank for selectively admitting the substantially constant pressure as a function of temperature to the storage tank. A control selectively operates the tank regulator in response to given conditions, such as temperature conditions, in the storage tank.
