The invention provides a multi-stage unscrewing wing with a continuous aerodynamic configuration, and belongs to the field of aircrafts. The aircraft comprises an aircraft base body, a first unscrewing wing support, a second unscrewing wing support, a third unscrewing wing support, an air supply and control system and an airfoil skin, the two ends of a first wing front edge are hinged to the aircraft base body and a first rear wing respectively, and a first metal air bag can drive the first wing front edge to rotate so that the first rear wing can stretch; the two ends of the second wing front edge are hinged to the aircraft base body and the second rear wing correspondingly, the second metal air bag can drive the second wing front edge to rotate, and the second wing front edge drives the second rear wing to stretch; the two ends of the third wing front edge are hinged to the aircraft base body and the third rear wing correspondingly, and the third metal air bag is located below the third wing front edge and can drive the third wing front edge to rotate so that the third rear wing can stretch. The airfoil can be driven to perform multi-stage deformation, and the problems that a deformation wing driving and transmission device is heavy, the airfoil deformation unfolding and folding ratio is low, and the continuity of the aerodynamic configuration of the multi-stage deformation airfoil is poor can be solved.
本发明提出一种具有连续气动外形的多级旋开翼,属于飞行器领域。它包括飞行器基体、第一旋开翼支架、第二旋开翼支架、第三旋开翼支架、供气及控制系统和翼面蒙皮,第一翼前缘的两端分别与飞行器基体和第一后翼铰接,第一金属气囊能驱动第一翼前缘转动,使第一后翼伸展;第二翼前缘的两端分别与飞行器基体和第二后翼铰接,第二金属气囊能驱动第二翼前缘转动,使第二翼前缘带动第二后翼伸展;第三翼前缘的两端分别与飞行器基体和第三后翼铰接,第三金属气囊位于第三翼前缘的下方,能驱动第三翼前缘转动,使第三后翼伸展。它能够驱动翼面进行多级变形,可解决变形翼驱动及传动装置繁重、翼面变形展收比低以及多级变形翼面气动外形的连续性差等问题。
