Title (EN) MULTICOPTER

(JA) マルチコプタ
Abstract:
(EN) A multicopter 10 including: four single rotors 40b, 42b, 46b, 48b; and two pairs of coaxial contra-rotating rotors 44c, 44d and 50c, 50d. In the planar view, these eight rotors are provided at the vertices of a hexagon and are arranged so as to be symmetrical around a first line L1 extending in the front/rear direction along a center point P1 of the hexagon. One of the single rotors 40b, 42b, 46b, and 48b is arranged in each region partitioned by the first line L1 and a second line L2 extending in the left/right direction so as to be orthogonal to the first line L1. The two pairs of coaxial contra-rotating rotors 44c, 44d and 50c, 50d are arranged above the second line L2.
(FR) La présente invention porte sur un multicoptère 10 comprenant : quatre rotors uniques 40b, 42b, 46b, 48b ; et deux paires de rotors coaxiaux contrarotatifs 44c, 44d et 50c, 50d. Dans la vue en plan, ces huit rotors sont disposés aux sommets d'un hexagone et sont agencés de manière à être symétriques autour d'une première ligne L1 s'étendant dans la direction avant/arrière le long d'un point central P1 de l'hexagone. L'un des rotors uniques 40b, 42b, 46b et 48b est disposé dans chaque région et est divisé par la première ligne L1 et une seconde ligne L2 s'étendant dans la direction gauche/droite de façon à être orthogonale à la première ligne L1. Les deux paires de rotors coaxiaux contrarotatifs 44c, 44d et 50c, 50d sont disposées au-dessus de la seconde ligne L2.
(JA) マルチコプタ10は、4つのシングルロータ40b,42b,46bおよび48bと、2組の同軸二重反転ロータ44c,44dおよび50c,50dとを含む。平面視において、これらの8個のロータは、6角形の頂点に設けられ、6角形の中心点P1を通って前後に延びる第1線L1に対して線対称に配置される。平面視において、シングルロータ40b,42b,46bおよび48bは、第1線L1と第1線L1に直交するように左右方向に延びる第2線L2とによって区画される領域に1つずつ配置され、2組の同軸二重反転ロータ44c,44dおよび50c,50dは、第2線L2上に配置される。
