The invention provides a morphing wing integrating telescopic variable-elongation and rotary variable-sweepback functions and a morphing method. The morphing wing comprises an inner wing section, an outer wing section and an elastic skin, the inner wing section and the outer wing section are positioned in the same spanwise plane; the inner wing section stretches and retracts in the spanwise plane along the spanwise direction of the wing, so that the span length of the inner wing section is adjusted; the outer wing sections rotate in the chordwise direction relative to the inner wing sections in the spanwise plane, and then the sweepback angles of the outer wing sections are adjusted. By adjusting the extension length and the sweepback angle of the wings, the lift force of the aircraft during low-speed flight is improved, and the resistance of the aircraft during high-speed flight is reduced. Specifically, the extension length of the wings is increased during low-speed flight to improve lift force, and the extension length is reduced and the sweepback angle is increased during high-speed flight to reduce resistance. The optimal aerodynamic performance can be achieved no matter in a low-speed flight state or a high-speed flight state, and the adaptability and the flight performance of the aircraft are remarkably improved.

    本发明提供一种集成伸缩变展长和旋转变后掠功能的变体机翼及变体方法,包括内翼段、外翼段和弹性蒙皮;内翼段和外翼段位于同一个展向平面内;内翼段在展向平面内沿机翼展向进行伸缩运动,进而调节内翼段展长;外翼段在展向平面内相对于内翼段进行弦向方向的旋转运动,进而调节外翼段的后掠角。本发明通过调整机翼的展长和后掠角,兼顾飞行器提高低速飞行时的升力和降低高速飞行时的阻力。具体而言,在低速飞行时增加机翼展长以提升升力,而在高速飞行时减小展长并增大后掠角以降低阻力。本发明实现无论在低速还是高速飞行状态下,都能达到最佳的气动性能,显著提升了飞行器的适应性和飞行性能。
