The invention discloses a self-adaptive paddle which comprises a paddle main body and a paddle tip mechanism, the paddle tip mechanism can rotate relative to the paddle main body, and the paddle tip mechanism comprises a paddle tip main body and a trailing edge winglet capable of rotating relative to the paddle tip main body. When the blade tip mechanism is flush with the blade main body and the trailing edge winglet is flush with the blade tip main body, the blade can work as a common integral blade; when the aircraft cruises at a high speed, the blade tip mechanism can be rotated to be turned upwards, the generation position of a blade tip vortex is changed, then induced resistance borne by the blade is reduced, and the aerodynamic load of the blade is optimized; when the blade tip mechanism is overturned relative to the blade main body, the relative angle between the trailing edge winglet and the blade tip main body can be adjusted, so that the aerodynamic load of the blade is further reduced, and the trailing edge winglet can be used for providing yawing moment for the blade. The invention further provides an airplane which comprises an airplane body and the self-adaptive paddle, and the end, away from the paddle tip mechanism, of the paddle body is connected with the airplane body.

    本发明公开一种自适应桨叶,包括桨叶主体和桨尖机构,桨尖机构能够相对于桨叶主体转动,且桨尖机构包括桨尖主体和能够相对于桨尖主体转动的后缘小翼。当桨尖机构与桨叶主体保持平齐,后缘小翼与桨尖主体保持平齐时,桨叶可作为普通整体式桨叶工作;在飞机进行高速巡航时,可转动桨尖机构使其上翻,改变桨尖涡的发生位置,进而降低桨叶受到的诱导阻力,优化桨叶的气动载荷;在桨尖机构相对于桨叶主体翻转的同时,可调整后缘小翼与桨尖主体的相对角度,从而进一步降低桨叶的气动载荷,还能够利用后缘小翼为桨叶提供偏航力矩。本发明还提供一种飞机,包括机身和上述的自适应桨叶,桨叶主体远离桨尖机构的一端与机身相连。
