The invention discloses a rotor wing propeller device, and belongs to an airfoil type device for aircraft wing or fluid power generation. The device comprises a plurality of blades (1), a base (2) and a transmission part (3), the blades (1) are arranged on the base (2) or the transmission part (3), the front blades adjacent to each other in the front-back direction serve as canards of the rear blades, and efficiency is improved by means of wingtip vortexes. According to the rotor wing propeller device, the combined blades are adopted to form a canard layout, low-speed rotation is achieved, and vibration and noise are effectively reduced; and the wingtip vortex is utilized, and the goose-array flight mode is simulated, so that the efficiency is improved.
本发明公开一种旋翼螺旋桨装置,属于飞行器机翼或流体发电的一种翼型装置。本发明包括多个桨叶(1)、机座(2)和传动部件(3),所述桨叶(1)设置在所述机座(2)上或所述传动部件(3)上,且前后相邻的前方桨叶作为后方桨叶的鸭翼,促进利用翼尖涡流提高效率。本发明旋翼螺旋桨装置采用组合桨叶构成鸭翼布局,低速旋转,有效减小振动和噪音;且将翼尖涡流加以利用,模仿雁阵飞行方式提高效率。
