Abstract
A thrust generator for a rotorcraft includes: a support part detachably mounted to a base provided in the rotorcraft; a rotor shaft rotatably supported by the support part; multiple rotating blades joined to the rotor shaft; and a drive unit detachably mounted to the support part or the base, wherein an output shaft of the drive unit is detachably connected to the rotor shaft.
Claims6
A thrust generator for a rotorcraft, the thrust generator comprising:
- a support part detachably mounted to a base provided in the rotorcraft;
- a rotor shaft rotatably supported by the support part;
- multiple rotating blades joined to the rotor shaft;
- and
- a drive unit detachably mounted to the support part or the base,
- wherein the drive unit comprises an electric motor having a motor output shaft, and a speed reducer that decelerates a driving force of the electric motor and transfers a decelerated driving force to the rotor shaft,
- the speed reducer is detachably mounted to the support part,
- the motor output shaft, an output shaft of the speed reducer, and the rotor shaft are arranged coaxially,
- one of the rotor shaft and the output shaft of the speed reducer is provided with a spline shaft part, and
- another of the rotor shaft and the output shaft of the speed reducer is provided with a spline hole into which the spline shaft part is detachably fitted.
