    Abstract: An integrated APU-generator constants speed drive system having various features is disclosed. The system may have a gearbox having a differential with a constant speed gearbox output and a hydraulic output controller control shaft. The system may have a hydraulic output speed controller that adjusts the angular velocity of the hydraulic output controller control shaft of the differential. In response, the differential may adjust the angular velocity of the constant speed gearbox output. In this manner, the angular velocity of the constant speed gearbox output may be maintained at a substantially constant angular velocity. A generator may be driven by the constant speed gearbox output. By maintaining the constant speed gearbox output at a substantially constant angular velocity, an alternating current generated by the generator may be maintained at a substantially constant frequency.

    Abstract: A torsion shaft assembly includes a torque carrying shaft including a driven end configured for receiving torque input to the torque carrying shaft and a driving end configured for outputting torque output from the toque carrying shaft. The torque carrying shaft includes an axial facing damping interface surface axially between the driven end and the driving end. A friction tube is disposed outboard of the torque carrying shaft. The friction tube is connected at a first axial location to be driven by the torque carrying shaft. The friction tube includes an axial facing damping interface surface that abuts the axial facing damping interface surface of the torque carrying shaft, forming a damping interface to provide frictional dampening against angular vibrations occurring as differential angular displacement between the driven end and the driving end of the torque carrying shaft.

    Abstract: An electric machine rotor assembly includes a rotor core defining a rotor axis. Windings are seated in the rotor core. A plurality of wedges circumferentially spaced apart around the rotor core relative to the rotor axis. Each rotor core extends axially and separates between two respective portions of the windings. A supply end plate is mounted at a first axial end of the rotor core. A return end plate is mounted at a second axial end of the rotor core opposite the first axial end. A flow path for coolant fluid extends through the supply end plate into the wedges, through the wedges and into the return end plate, and through the return end plate.
