Provided is a multicopter with which it is possible to minimize the occurrence of the vortex ring state in rotor blades, and to control lift and thrust efficiently and with a high degree of precision. This multicopter comprises a plurality of rotor blades positioned in a radial manner with respect to a frame, wherein at least one of the plurality of rotor blades is equipped with a cylindrical duct that surrounds the periphery of the rotor blade, and the duct is formed in a shape such that the flow of air from the intake side to the exhaust side of the rotor blade is uneven in the circumferential direction of the duct. |
