METHOD OF CONTROLLING UNMANNED AIR VEHICLE

To enable an unmanned air vehicle to safely and efficiently fly while securing a flight distance and flight time.SOLUTION: An unmanned air vehicle 3 comprises: a flight control device; an annular ring body in which a part of a ring can be opened and closed; a current generating device; a ring opening/closing device; and a power supply device. The power supply device of one unmanned air vehicle is electrically connected via a cable C to the power supply device of another unmanned air vehicle in order to be in a power supply capable state. Two unmanned flight bodies perform formation flight while maintaining the above described state to approach an overhead wire 2, open a part of the respective annular ring while flying to accommodate the overhead wire inside the respective ring bodies, close a part of the respective rings while flying, supply a thrust generator or the flight control device with power which is based on current generated in a conductive coil according to electromagnetic induction action of current flowing in the overhead wire, and fly along the overhead wire while the overhead wire is accommodated inside the ring.SELECTED DRAWING: Figure 11 【課題】飛行距離や飛行時間を確保しつつ無人飛行体を安全かつ効率よく飛行させる。【解決手段】無人飛行体３は、飛行制御装置、環の一部を開閉可能な環状のリング体、電流発生装置、リング開閉装置、及び電力供給装置、を備え、一方の無人飛行体の電力供給装置が他方の無人飛行体の電力供給装置に電力を供給可能な状態となるようにケーブルＣを介して電気的に接続し、２つの無人飛行体が、上記状態を維持したまま編隊飛行して架空電線２に接近し、飛行しつつ夫々のリング体の環の一部を開いて夫々の環の内側に架空電線を収容し、飛行しつつ夫々の環の一部を閉じ、架空電線を流れる電流の電磁誘導作用により導電コイルに生じる電流に基づく電力を推力発生装置又は飛行制御装置に供給し、環の内側に架空電線を収容した状態で架空電線に沿って飛行する。【選択図】図１１
