The invention aims to realize small size and light weight of rotor aircrafts such as multi-rotor aircrafts, unmanned aerial vehicles or hovercars. In a rotorcraft provided with a plurality of rotors on a fuselage, round wings for generating a coanda effect are respectively arranged below the plurality of rotors, each round wing has an annular curved surface of which the upper surface is bent upward to form a convex shape, rotation of the plurality of rotors generates a first lift force, and the coanda effect of the plurality of round wings generates a second lift force. The jet flow of air deflects downwards along the upper surfaces of the circular wings to generate third lift force.

    本发明的目的在于实现多旋翼飞行器、无人机或飞行汽车等旋翼航空器的小型轻量化。在机身上设置有多个旋翼的旋翼航空器中,在所述多个旋翼的下方分别配置有产生康达效应的圆形翼,所述圆形翼具有上表面向上方弯曲成凸形的环状曲面,所述多个旋翼的旋转产生第一升力,多个所述圆形翼的康达效应产生第二升力,空气的射流沿着多个所述圆形翼的上表面分别向下偏转而产生第三升力。
