The invention belongs to the technical field of guided weapons, and particularly discloses an airfoil folding and unfolding device and an aircraft. The airfoil folding and unfolding device comprises a supporting body and airfoil assemblies, the number of the airfoil assemblies is multiple, and each airfoil assembly comprises an airfoil and a connecting shaft; the airfoils in the airfoil assemblies are arranged at intervals through the connecting shafts and then rotatably connected to the supporting body, and the airfoils have the unfolded state that the airfoils rotate to be separated from one another and the folded state that the airfoils rotate to be overlapped with one another. The problems that an airfoil folding mechanism is difficult to manufacture and integrate, high in cost, low in space utilization rate and incapable of meeting the requirements of large airfoil and large maneuverability are solved.

    本发明属于制导武器技术领域,具体公开了一种翼面折叠展开装置及飞行器。翼面折叠展开装置包括:支撑体和翼面组件,翼面组件为多组,各翼面组件均包括翼面和连接轴;多组翼面组件内的翼面通过连接轴间隔设置后,可转动地连接在支撑体上,且多个翼面具有转动至相互分离的展开状态和转动至相互重叠的折叠状态。本发明解决了翼面折叠机构难于制造和集成化、成本较高、空间利用率低,无法满足大翼面大机动性的要求的难题。
