Abstract
(EN)
[Problem] To generate downwash with a stronger wind force in a drone having rotary wings. [Solution] A drone 100 is provided with a body 110 and a plurality of rotary wings 101 arranged around the body so as to form a plurality of pairs each disposed vertically, and the drone 100 moves through generating thrust with downwash generated downward of lower-side rotary wings 101-1b, 101-2b, 101-3b, 101-4b. Upper-side rotary wings 101-1a, 101-2a, 101-3a, 101-4a and the lower-side rotary wings rotate in directions opposite to each other. The diameters of the lower-side rotary wings are smaller than the diameters of the upper-side rotary wings.

Le problème décrit par la présente invention est de générer une déflexion vers le bas avec une force de vent plus forte dans un drone ayant des ailes rotatives. La solution selon l'invention porte sur un drone qui est pourvu d'un corps (110) et d'une pluralité d'ailes rotatives (101) agencées autour du corps de façon à former une pluralité de paires disposées chacune verticalement, et le drone (100) se déplace par génération de poussée avec une déflexion vers le bas générée plus bas que les ailes rotatives côté inférieur (101-1b, 101-2b, 101-3b, 101-4b). Des ailes rotatives côté supérieur (101-1a, 101-2a, 101-3a, 101-4a) et les ailes rotatives côté inférieur tournent dans des directions opposées l'une à l'autre. Les diamètres des ailes rotatives côté inférieur sont plus petits que les diamètres des ailes rotatives côté supérieur.

【課題】回転翼を有するドローンにおいて、より強い風力で下降気流を発生させる。 【解決策】 本体110と、本体の周辺に配置され、上下に対を成して複数対配置される複数の回転翼101と、を備え、下段の回転翼101-1b,101-2b,101-3b,101-4bの下方へ向かって生じる下降気流により推力を発生させて移動するドローン100であって、上段の回転翼101-1a,101-2a,101-3a,101-4aおよび下段の回転翼は、互いに反対方向に回転し、下段の回転翼の直径は、上段の前記回転翼の直径より小さい。
