The invention discloses a rotor wing system with a rotor wing unfolding auxiliary mechanism and an aircraft. The rotor wing system comprises an upper rotor wing unfolding auxiliary assembly, an upper rotor wing power system, a lower rotor wing unfolding auxiliary assembly and a lower rotor wing power system. The upper rotor wing unfolding auxiliary assembly comprises a thrust rod and a thrust rod base; the upper rotor wing power system comprises an upper power motor, an upper propeller hub, an upper variable pitch connecting piece, an upper propeller clamp and an upper propeller blade. According to the rotor wing system with the rotor wing unfolding auxiliary mechanism and the aircraft, when the size and the weight of blades of a medium-large unmanned aerial vehicle are increased, the auxiliary unfolding structure can replace a steering engine to bear huge torque caused by centrifugal force in the stage of starting to open the blades when the rotors are automatically unfolded; and when the blades are opened to a certain angle by centrifugal force and lift force, the auxiliary structures are separated from the blades. And after the unmanned aerial vehicle enters a working state, the variable pitch of the blades is not interfered. And the effect of protecting the paddle and the variable pitch mechanism is achieved.

    本发明公开了一种带旋翼展开辅助机构的旋翼系统及飞行器,包括上旋翼展开辅助组件、上旋翼动力系统、下旋翼展开辅助组件以及下旋翼动力系统;所述的上旋翼展开辅助组件包括止推杆、止推杆底座;所述的上旋翼动力系统包括上动力电机、上桨毂、上变距连接件、上桨夹以及上桨叶。本发明的带旋翼展开辅助机构的旋翼系统及飞行器,在中大型无人机,当桨叶尺寸和重量较增大时,此种辅助展开结构可以在旋翼自动展开的启动打开桨叶阶段代替舵机承受离心力造成的巨大扭矩,当桨叶被离心力和升力打开至一定角度时,辅助结构脱离桨叶。在无人机进入工作状态后,不干涉桨叶的变距。起到保护桨叶保护变距机构的作用。
