The light coaxial unmanned aerial vehicle full-waving propeller hub comprises propeller hub fixing seats, the propeller hub fixing seats are symmetrically installed at the two ends of a main shaft, the propeller hub fixing seats are fixedly connected with pulling and twisting strips, the pulling and twisting strips are symmetrically arranged on the two sides of the propeller hub fixing seats, and the tail ends of the pulling and twisting strips are fixedly connected with propeller clamp rocker arms and propeller clamps. The propeller hubs are applied to the small coaxial unmanned helicopter and installed at the two ends of the main shaft, the middle steering engine controls the inclinator, the inclinator transmits, controls and adjusts the posture of the propeller hubs, and finally control over the propeller blades is achieved. The propeller hub is provided with complete flapping hinges and variable pitch hinges to control the propeller blades, accurate and stable control over the propeller blades can be achieved, and the flight attitude of a fuselage is more stable. Meanwhile, weight reduction is fully considered in design, the dead weight is reduced to the minimum, and the effective load of the aircraft is improved.
本发明公开了一种轻型共轴无人机全挥舞桨毂,包括桨毂固定座,所述桨毂固定座对称安装于主轴两端,所述桨毂固定座上固定连接有拉扭条,所述拉扭条对称设置于桨毂固定座两侧,所述拉扭条末端与桨夹摇臂、桨夹固定连接。本设计桨毂应用于小型共轴无人直升机,安装于主轴两端,由中间的舵机控制倾斜器,倾斜器传递控制,调整桨毂姿态,最终实现对桨叶的控制;本设计的桨毂,有完整的挥舞铰和变距铰控制桨叶,能实现对桨叶精准稳定的控制,机身飞行姿态更加稳定。同时设计上充分考虑减重,将自重降到最低,提高飞机有效载荷。
