The invention discloses an overturning-unscrewing multi-stage deformation wing suitable for cross-domain flight, and belongs to the technical field of aircrafts. The problems that an existing cross-domain flight deformation wing technology cannot simultaneously solve the problems that driving and transmission devices are heavy, the wing surface deformation unfolding and folding ratio is low, and the continuity of the aerodynamic configuration of a multi-stage deformation wing surface is poor are solved. Comprising a bottom beam, a first-stage wing front edge, a first-stage folding and unfolding assembly, a second-stage wing front edge and a second-stage folding and unfolding assembly, and the front end of the first-stage wing front edge is hinged to the front end of the bottom beam. Based on the geometric layout of the combination of the folding and unfolding assembly and the wing leading edge and the thought of graded arrangement and continuous unfolding of the second-stage unscrewing wing, the second-stage unscrewing wing surface structure is provided, and the deformation wing has four aerodynamic profiles under different flight working conditions of a completely-folded wing, wing surface overturning, a first-stage unscrewing wing and a second-stage unscrewing wing and is suitable for cross-domain flight.
一种适用跨域飞行的翻转‑旋开多级变形翼,属于飞行器技术领域。本发明解决了现有跨域飞行变形翼技术无法同时解决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的问题。包括飞行器基体及变形翼骨架,飞行器基体与变形翼骨架之间通过翻转组件连接,所述变形翼骨架包括底梁、一级翼前缘、一级折展组件、二级翼前缘及二级折展组件,一级翼前缘的前端部与底梁的前端部铰接。基于折展组件与翼前缘相结合的几何布局和二级旋开翼分级排布、连续展开的思想,提出了二级旋开的翼面结构,变形翼具有完全折叠翼、翼面翻转、一级旋开翼、二级旋开翼四种不同飞行工况下的气动外形,适用于跨域飞行。
