PROBLEM TO BE SOLVED: To provide an unmanned aerial vehicle (UAV) capable of obtaining energy from an ascending air current and an operation method of the unmanned aerial vehicle.SOLUTION: An unmanned aerial vehicle having a gliding capability is provided which includes a power generator 140 driven by a rotary wing 190 and a battery 200. This unmanned aerial vehicle can operate in an energy obtaining mode where the rotary wing 190 is driven and rotated by movement of the unmanned aerial vehicle and the rotary wing 190 drives the power generator 140; and the power generator 140 charges the battery 200; in this energy obtaining mode, thanks to regenerative braking of the power generator 140, a forward speed of the unmanned aerial vehicle declines to generate electricity, and the unmanned aerial vehicle is prevented from flying exceeding a predetermined altitude. |
