The invention belongs to the technical field of rotor aerodynamic design, and discloses an unequal-diameter coaxial double-rotor. The double-rotor comprises the upper rotor and the lower rotor, the upper rotor and the lower rotor are coaxial, and the diameter of the upper rotor is larger than that of the lower rotor. The coaxial double rotors are adopted, the diameters of the upper rotor and the lower rotor are different, the favorable interference of the lower rotor on the upper rotor is fully utilized, meanwhile, the adverse interference of the upper rotor on the lower rotor can be reduced,and compared with a conventional equal-diameter coaxial double rotor, the coaxial double rotor has the obvious hovering efficiency advantage.

    本发明属于旋翼气动设计技术领域,公开了一种不等直径共轴双旋翼。所述双旋翼包括:上旋翼和下旋翼,所述上旋翼和下旋翼共轴,且所述上旋翼的直径大于所述下旋翼的直径。采用共轴双旋翼,上下旋翼直径不同,充分利用下旋翼对上旋翼的有利干扰,同时又能减小上旋翼对下旋翼的不利干扰,比常规等直径共轴双旋翼具有明显的悬停效率优势。
