The invention discloses a deformable high-speed helicopter stub wing. The wing comprises a driving element, a frame assembly and a skin, the driving element and the frame assembly are both rotatably connected with a helicopter fuselage the driving element is rotatably connected with the frame assembly, the driving element can drive the frame assembly to reciprocate, and the frame assembly is of anunstable polygonal structure. One end of the frame assembly is rotationally connected with the helicopter fuselage, and when the driving element drives the frame assembly to reciprocate, the frame assembly can deform, so that the maximum distance between the frame assembly and the helicopter fuselage is changed. When a helicopter hovers, the driving element drives the frame assembly to move, andthe area of the frame assembly reaches the minimum. Along with the gradual increase of the forward flying speed of the helicopter, the driving element drives the frame assembly to rotate reversely torealize the unfolding of the helicopter stub wing, and the helicopter stub wing is completely unfolded to provide larger lift force after the wake flow of a main rotor of the helicopter deviates fromthe fuselage.
本发明公开一种可变形的高速直升机短翼,包括驱动元件、框架组件和蒙皮,驱动元件和框架组件均可转动地与直升机机身相连,驱动元件与框架组件转动连接,驱动元件能够带动框架组件往复运动,框架组件为不稳定的多边形结构,框架组件一端与直升机机身转动连接,在驱动元件带动框架组件往复运动时,框架组件能够产生形变,从而使框架组件与直升机机身之间的最大距离发生变化。在直升机悬停时,驱动元件带动框架组件运动,框架组件的面积达到最小。随着直升机前飞速度逐渐增加,驱动元件带动框架组件反向转动,实现直升机短翼“展开”,在直升机主旋翼尾流偏离机身后直升机短翼完全展开以提供更大的升力。
