The invention relates to a rotor wing of a rotorcraft and the rotorcraft. The rotor wing comprises a paddle and a paddle hub, the paddle is installed on a driving assembly of the rotorcraft through the paddle hub, the paddle comprises a paddle root, a paddle tip, an upper wing surface and a lower wing surface, the upper wing surface and the lower wing surface are oppositely arranged up and down, and one side of the upper wing surface and one side of the lower wing surface are connected to form a front edge; and the other side is connected to form a trailing edge, the upper wing surface is defined by an upper wing surface characteristic line formed by (kx, ky, kz) defined by a plurality of coordinate pairs, and the lower wing surface is defined by a lower wing surface characteristic line formed by (kx, ky, kz) defined by a plurality of coordinate pairs. The rotor wing disclosed by the invention can reduce an air resistance, improve tension and efficiency, prolong the endurance time of the rotorcraft, reduce a noise generated during flight of the rotorcraft, and improve user experience.
本公开涉及一种旋翼飞行器的旋翼和旋翼飞行器,其中旋翼包括桨叶和桨毂,桨叶通过桨毂安装于旋翼飞行器的驱动组件上,桨叶包括桨根、桨尖以及上下相对设置的上翼面和下翼面,上翼面和下翼面的一侧连接形成前缘,另一侧连接形成所述尾缘,上翼面由通过多个坐标对限定的(kx,ky,kz)构成的上翼面特征线所限定,下翼面由通过多个坐标对限定的(kx,ky,kz)构成的下翼面特征线所限定。本公开的旋翼能够减少空气的阻力,提高拉力和效率,增加旋翼飞行器的续航时间,此外还能够减少飞行器在飞行时产生的噪音,提升用户体验。
