Abstract: A compounding drive includes an input member, an epicyclical gear arrangement connected to the input member, an output member connected to the epicyclical gear arrangement, and a hydraulic pump/motor set. The hydraulic pump/motor set connects the epicyclical gear arrangement to the output member through an overrunning clutch for unidirectional communication of mechanical rotation between the input member and the output member. Engine arrangements, aircraft, and methods of compounding internal combustion engines are also described.

Abstract: A hybrid drive system can include a shaft, an electrical machine comprising a rotor and a stator, and a mechanical disconnect system connecting the rotor to the shaft. The mechanical disconnect system is configured to mechanically connect the rotor to the shaft in a first state and to mechanically disconnect the rotor from the shaft in a second state such that rotor does not drive the shaft or such that the rotor is not driven by the shaft. The rotor can be a permanent magnet rotor, for example.

Abstract: An automatic disconnect coupling includes a retainer and a biasing member. The biasing member is coupled to the retainer and is arranged to communicate excitation from a generator input member to the retainer. The retainer and the biasing member have a fundamental frequency tuned to the rotational speed of the generator input member to automatically disconnect the input member from a drive member when rotating unbalance of the input member exceeds a predetermined level.

Abstract: Embodiments herein relate to piece-part, sub-assembly, assembly, and component levels of a differential composed of a sun gear configuration and utilized in an integrated drive generator. An integrated drive generator is a hydro-mechanical transmission that drives a synchronous salient pole generator. The integrated drive generator is a constant speed output, variable speed input transmission that includes the differential and a hydraulic unit. In general, the integrated drive generator utilizes the variable speed input from an accessory gear box of an engine to drive or control a hydraulic unit, which in turn drives or controls a churn leg member of the differential. As the differential is driven, speeds of each speed member of the differential are then summed to generate the constant speed output to drive the synchronous salient pole generator.

Abstract: A generator assembly includes a generator shaft defining an interior vent space. A valve assembly is positioned within the vent space configured to selectively allow venting of air through the generator shaft. A radial vent is positioned within the valve assembly configured to prevent oil from flowing through the vent space during operation and release air through the vent space during shutdown.

Abstract: A pressure switch including a pressure chamber and a moving disc. The moving disc is moveable in response to a pressure in the pressure chamber to cause contact between a moveable contact and a fixed contact. An orifice communicates a fluid pressure into the pressure chamber. The orifice provides a tortuous path for a fluid flow to reach the pressure chamber. An oil supply system and a generator are also disclosed.
