The invention belongs to the field of aircraft structure design, and relates to a variable camber wing trailing edge structure based on a sliding groove. Comprising a trailing edge cabin beam, a fixing support, a movement mechanism assembly, a movement mechanism supporting rod, a plurality of stringers, a trailing edge upper skin, a trailing edge lower skin, lugs with sliding grooves and sliding groove pin rollers. In the variable camber process of the variable camber wing trailing edge, the relative positions of the trailing edge skin and the trailing edge movement mechanism are changed. The relative position change of the trailing edge skin and the movement mechanism is solved by adopting a sliding groove mode, so that the movement of the movement mechanism is coordinated with the deformation of the skin in the bending degree changing process of the trailing edge, and the skin deformation fairing requirement is met; the trailing edge skin is connected with the movement mechanism in a sliding groove mode, the requirement for wing thickness change of the trailing edge of the variable-camber wing in the variable-camber process can be met, and the requirement for the optimal aerodynamic performance is met.
本发明属于飞行器结构设计领域,涉及一种基于滑槽的变弯度机翼后缘结构。包括:后缘舱梁、固定支架、运动机构组件、运动机构支杆、若干根长桁、后缘上蒙皮、后缘下蒙皮、带滑槽耳片、滑槽滚柱;在变弯度机翼后缘变弯度过程中,后缘蒙皮与后缘运动机构的相对位置发生变化。后缘蒙皮与运动机构通过采用滑槽的方式解决两者相对位置变化,使后缘在变弯度过程中运动机构的运动与蒙皮变形相协调,满足蒙皮变形光顺要求;后缘蒙皮与运动机构通过采用滑槽的方式连接,可以满足变弯度机翼后缘在变弯度过程中翼型厚度变化的要求,满足最优气动性能要求。
