    摘要： A power generation unit for generating electric power within a rotating reference frame includes a generator and a gear assembly. The generator has a plurality of first generator parts disposed concentrically with and radially outward from a plurality of second generator parts. The gear assembly is rotatably attached to the second generator parts and configured to allow relative rotation between the first and second generator parts caused by a single rotating component. The generator and the gear assembly are axially disposed along a common rotational axis.

    摘要： An aircraft is provided and includes a gearbox housing through which a drive shaft configured to drive propeller rotation extends and a pitch control apparatus. The pitch control apparatus includes a drive element coupled to an exterior of the gearbox housing and an annular electro-mechanical actuator (EMA) configured to convert rotational energy generated by the drive element to thereby control a pitching of propeller blades about corresponding pitch axes.

    摘要： A propeller assembly has a plurality of propeller blades, and a pitch change mechanism including at least one motor. A drive input drives the plurality of propeller blades to rotate about a central drive axis. The pitch change mechanism is operable upon driving of the motor to move the propeller blades relative to the drive input. The drive input includes a drive input gear transmission to change a pitch angle of the blades when the blades are moved relative to the drive input by the pitch change mechanism. Further, a method of operating a propeller assembly to change a pitch angle is disclosed and claimed.
