The present invention relates to a multicopter, which is an aerial vehicle including a plurality of rotors. More specifically, the present invention relates to a multicopter including a rotor to which an annular airfoil is applied to generate lift by passing horizontal airflow generated through rotation through the annular airfoil. According to the present invention, the multicopter including a rotor to which an annular airfoil is applied comprises: a flight body; a plurality of rotors arranged radially outside the flight body in a radial direction to generate lift; and a plurality of spokes connecting the flight body and the rotor, respectively. The rotor includes: an annular airfoil having an airfoil shape in cross section, with a leading edge formed radially inside and a trailing edge formed radially outside; a blowing unit disposed at the center of the annular airfoil and generating an airflow from the leading edge to the trailing edge by rotation; and a power unit connected to the blowing unit and having a rotational shaft for rotating the blowing unit.

    본 발명은 복수의 로터를 포함하는 비행체인 멀티콥터에 관한 것으로, 더욱 상세하게는 회전을 통해 발생하는 수평 방향 기류를 환형의 에어포일에 통과시켜 양력을 발생시키는 환형에어포일을 적용한 로터를 포함하는 멀티콥터에 관한 것이다.
