To provide a flight safety frame which is light weight and has high intensity, the flight safety frame for drone (small sized unmanned aircraft).SOLUTION: There is provided a flight safety frame for drone comprising: a surrounding frame (E) for surrounding whole body of a propeller (13) of a drone (A) from a lateral direction; and a plurality of cross beams (17) extended laterally in a partial bridge state to a halfway part of the surrounding frame to approach a tip of an arm (11) protruded to a radial direction of a machine body (10) in a drone. The surrounding frame and the cross beams are formed of a straight tube (Sm) and/or curved pipe (Cm) formed of a carbon fiber-reinforced plastic material, the halfway part of the cross beam is detachably attached to a tip of the arm protruded to the radial direction of the machine body on the drone, by relationship setting.SELECTED DRAWING: Figure 1

    【課題】ドローン(小型無人航空機)用の軽く高強度な飛行安全フレームを提供する。【解決手段】ドローン(A)のプロペラ(13)を横方向から全体的に包囲する包囲枠(E)と、ドローンにおける機体(10)の放射方向へ張り出すアーム(11)の先端部と接近するように、上記包囲枠の途中へ部分的な橋渡し状態に横架された複数本のクロスビーム(17)とを備え、上記包囲枠とクロスビームが炭素繊維強化プラスチック材の直管(Sm)又は/及び曲管(Cm)から成り、上記クロスビームの途中がドローンにおける機体の放射方向へ張り出すアームの先端部へ、着脱自在に取り付け使用されるように関係設定した。【選択図】図1
