The invention relates to a wing with a secondarily foldable structure, and solves the problem that the aerodynamic efficiency of the wing structure is affected due to the complex structure of the existing folding and unfolding mode. Comprising a main wing and an aileron (7) composed of a middle-section wing (2) and an outer-section wing (3), a middle-section wing rotating mechanism (4) connected with a fuselage (1) is installed on the middle-section wing (2), and a locking mechanism (5) and an outer-section wing unfolding driving mechanism (6) are installed between the junction surfaces of the outer-section wing (3) and the middle-section wing (2). The locking mechanism (5) is composed of a telescopic arc-shaped spring bolt installed on the combination face of the middle-section wing (2) and a groove formed in the combination face of the outer-section wing (3) and matched with the telescopic arc-shaped spring bolt, after folding, the lower surface of the outer-section wing (3) is attached to the lower surface of the middle-section wing (2), and the upper surface of the outer-section wing (3) is attached to the upper surface of the fuselage (1). Airflow disturbance on the surfaces of the wings is small, the fuselage is used for restraining unfolding of the wings, and the mechanism is simple and reliable.
本发明涉及一种结构可二次折叠的机翼,解决了现有折叠展开方式结构复杂,影响机翼结构气动效率的问题。包括由中段机翼(2)、外段机翼(3)组成的主翼和副翼(7),中段机翼(2)上装有和机身(1)连接的中段机翼旋转机构(4),外段机翼(3)与中段机翼(2)结合面之间安装有锁定机构(5)和外段机翼展开驱动机构(6),锁定机构(5)由安装在中段机翼(2)结合面上的可伸缩弧形锁舌和在外段机翼(3)结合面上开有的与可伸缩弧形锁舌相配合的凹槽构成,折叠后,外段机翼(3)下表面与中段机翼(2)下表面贴合,外段机翼(3)上表面与机身(1)上表面贴合。本发明对机翼表面气流扰动较小,使用机身约束机翼展开,机构简单可靠。
