First Embodiment
Hereinafter, a first embodiment of a power generation flying vehicle to which the present invention is applied will be described with reference to the drawings. In addition, arrow UP suitably shown by each figure has shown the perpendicular direction upper side. In the power generation flying body 10 of the present embodiment, the extending direction of the rotation shaft 16 of the rotary wing 14 at the time of hovering is referred to as the vertical direction. The vertical direction at the time of hovering coincides with the vertical direction, and lift is generated upward in the vertical direction.

  As shown in FIG. 1, the power generation flying body 10 of the present embodiment includes a flight main body 20 and a rotary wing 14. As also shown in FIGS. 2 to 4, the flight main body portion 20 has a central portion 22, an arm portion 24 and a skeleton portion 26. The central portion 22 is hollow, and includes a control unit 18 (motor control, flight control, power generation control, etc.), a communication antenna (not shown), a position sensor, a camera, a battery 40 and the like. The central portion 22 is disposed at the center of the flight main body 20 in plan view. Hereinafter, with the central portion 22 as a center, the direction away from the center of the central portion 22 in a plan view is referred to as the radially outer side, and the direction approaching the center of the central portion 22 is referred to as the radially inner side.

  The four arm portions 24 are provided and radially extend outward from the central portion 22 in a plan view. A motor generator 15 is attached to the tip of each of the arms 24. The motor generator 15 has a function as an electric motor (electric motor), and is provided with general members such as a rotor, a stator, a rotating shaft, and a bearing. It may be a direct current motor or an alternating current motor. The motor generator 15 also functions as a generator when the rotating shaft 16 rotates.

  Rotor blades 14 are attached around the rotation axis 16 of the motor generator 15. The rotary wings 14 rotate around the rotation shaft 16 of the motor generator 15 to generate lift.
