The invention discloses a self-adaptive unfolding coaxial rotor wing system which comprises an upper rotor wing system and a lower rotor wing system, and the upper rotor wing system comprises a propeller hub, an upper propeller clamp, an outer propeller clamp, an elastic module and rotor wings; the lower rotor wing system comprises a propeller hub, a lower propeller clamp, an outer propeller clamp, an elastic module and a rotor wing. A concise passive self-adaptive rotor wing unfolding mechanism is adopted, so that the self-adaptive unfolding and folding functions of the rotor wings are realized when the aircraft is switched between a non-working state and a working state. An outer paddle clamp structure is introduced into traditional paddle clamp design, the limiting and contact modes between paddle clamps are designed, friction in mechanism rotation is reduced, and the production and machining cost is reduced. Through arrangement of the position relation between the axis of the elastic module and the propeller clamp hinge, various different self-adaptive rotor wing unfolding mechanism configurations can be obtained, and proper configurations can be selected according to requirements in the specific implementation process. The method is applied to throwing type, launching type or cluster task folding type coaxial helicopters, and the application scenes of the coaxial helicopters are effectively expanded.

    本发明公开了自适应展开共轴旋翼系统,包括上旋翼系统和下旋翼系统,上旋翼系统包括桨毂、上桨夹、外桨夹,弹性模块、旋翼;下旋翼系统包括桨毂、下桨夹、外桨夹,弹性模块、旋翼。采用了简洁的被动自适应旋翼展开机构,实现飞行器在非工作状态和工作状态之间切换时旋翼的自适应展开和折叠功能。在传统桨夹设计中引入外桨夹结构,并对桨夹间的限位和接触方式进行了设计,减小了机构转动中的摩擦并降低生产加工成本。通过弹性模块轴线与桨夹铰链间的位置关系设置,可以获得多种不同的自适应旋翼展开机构构型,在具体实施过程中可根据需求选用合适的构型。本发明应用于抛投型、发射型或集群任务的折叠式共轴直升机,有效扩展了共轴直升机的应用场景。
