Kind Code:
A1
Abstract:
A multicopter 10 comprising: eight rotors arranged having gaps therebetween and so as to surround a center point P1 in the planar view; and a spraying device 52 having a plurality of nozzles 62, 64. In the planar view, the eight rotors are arranged symmetrically, including in the rotation direction relative to a first line L1. The same number of rotors are arranged on the left and right sides of the first line L1. In the side view, discharge ports 62a, 64a for each nozzle 62, 64 are positioned lower than the rotor. The discharge ports 62a, 64a for each nozzle 62, 64 are provided inside first regions R1, R2 on the left and right sides of the first line L1 in the planar view, said regions being formed by: the arcs and tangents of the rotation trajectory of each rotor tip; and a line that passes through the rotation axis of the foremost rotor and the rotation axis of the rearmost rotor.
