To smoothly load and unload cargo from an unmanned flight body.SOLUTION: An unmanned flight body of one embodiment comprises: a main body; a plurality of rotary wings provided on the main body; a wire for suspending an object from the main body; a hook attached to the wire; a winch for supporting a spool around which the wire is wound so as to rotate freely in a normal direction and a reverse direction, and rotating the spool in the normal direction for winding the wire and rotating the spool in the reverse direction for feeding the wire; and a controller for restricting rotation in the reverse direction of the spool when tension of the wire becomes a first threshold or smaller, and restricting rotation in the normal direction of the spool when the tension of the wire becomes a second threshold which is smaller than the first threshold and smaller than a gravity applied to the hook, or a value smaller than the second threshold.SELECTED DRAWING: Figure 2

    【課題】無人飛行体からの貨物の昇降を円滑に行えるようにする。【解決手段】本発明の一実施形態による無人飛行体は、本体と、前記本体に設けられた複数の回転翼と、前記本体から物体を吊り下げるためのワイヤと、前記ワイヤに取り付けられたフックと、前記ワイヤが巻かれたスプールを正転方向及び逆転方向に回転可能に支持し、前記スプールを正転方向に回転させることにより前記ワイヤを巻き取り、前記スプールを逆転方向に回転させることにより前記ワイヤを繰り出すウインチと、前記ワイヤの張力が第1閾値以下になると前記スプールの前記逆転方向における回転を制限し、前記ワイヤの張力が前記第1閾値よりも小さく且つ前記フックに作用する重力よりも小さな第2閾値以下になると前記スプールの前記正転方向における回転を制限するコントローラと、を備える。【選択図】図2
