The invention relates to the technical field of unmanned helicopters, and particularly discloses a seesaw type unmanned helicopter rotor structure and a chordwise dynamic balance trimming method. The rotor structure is simple in overall structure and convenient to operate, chordwise dynamic balance trimming of a rotor can be achieved under the condition that independent balance weight is not carried out, the dynamic balance trimming efficiency of the unmanned aerial vehicle rotor wing is greatly improved, and the trimming operation of dynamic balance of the unmanned aerial vehicle rotor wing is simplified. According to the method disclosed by the invention, the chordwise dynamic balance of the rotor wing can be quickly and conveniently adjusted without additionally adding a counter weight or adding a structure for mounting the counter weight. The weight of the counter weight can be effectively reduced; the dynamic balance adjustment time is shortened; the complexity of the aircraft structure is reduced; the maintenance time of the unmanned aerial vehicle is reduced. And the economy and the safety of the unmanned helicopter are improved.

    本发明涉及无人直升机技术领域,具体公开了一种跷跷板式无人直升机旋翼结构及弦向动平衡配平方法,本发明公开的旋翼结构,整体结构简单,操作方便,能够在不进行单独配重的情况下实现旋翼的弦向动平衡配平,极大的提高了无人机旋翼的动平衡配平效率,简化了无人机旋翼动平衡的配平操作。通过本发明公开的方法,能够快速便捷的调整旋翼的弦向动平衡,不需要额外增加配重,也无需增加安装配重的结构。能够有效的减小配重的重量;减少动平衡调整时间;减少飞机结构的复杂性;减少无人机的维护时间。提高了无人直升机的经济性和安全性。
