A gas turbine engine includes an engine core, a fan and a gearbox interconnecting the engine core and the fan. The engine core is configured to drive rotation of at least one shaft. The power gearbox is configured to transfer torque from the at least one shaft to an output shaft at a reduced rotational speed. The output shaft is coupled to the fan to drive the fan at the reduced speed and provide trust for the gas turbine engine.

A powertrain assembly comprises a motor assembly having a motor housing with a rotor assembly at least partially axially aligned with a stator and disposed within an interior portion of the motor housing. A motor shaft is coupled to the rotor assembly. The rotor assembly is configured to rotate within the interior portion of the motor housing. A gear system having a ring gear is disposed within the stator and at least partially axially aligned with the stator. The gear system further includes first and second gears. The first gear is configured to drive the second gear within the interior portion of the ring gear. An output shaft is operably coupled to the second gear and extending outwardly from the interior portion of the motor housing.

An engine synchronisation arrangement of an internal combustion engine having a crank-shaft and a camshaft geared together with a fixed rotation ratio includes a crank-shaft wheel cooperating with a first sensor and, a camshaft wheel cooperating with a second sensor, both wheels being provided with peripheral features. Both sensors detect the features and communicate to an ECU binary signals. The features of the crank-shaft wheel are arranged in a sequential pattern, and a sliding window of a specific width covers a unique set of features corresponding to a unique string of consecutive bits mapping to a unique angular position of the crank-shaft.

A demister for a gearing system includes a main body shaped as a disk having an inner annular rim coupled to an outer annular rim through a first wall and a second wall opposite from the first wall. A central opening is defined by the inner annular rim and extends between and through the first wall and the second wall. The main body is configured to be rotated about a central longitudinal axis to create centrifugal forces that separate oil mist particles from air. At least one fluid passage extends radially between and through the inner annular rim and the outer annular rim. The fluid passage(s) includes a fluid inlet opening in the outer annular rim and a fluid outlet opening in the inner annular rim. The fluid inlet opening is configured to accept incoming air. The fluid outlet opening is configured to discharge filtered air.
