DING LI

The invention provides a flexibly-deformable trailing edge variable camber wing. The wing includes: a variable camber rib comprising a plurality of rib sections and connecting plates, wherein every two adjacent rib sections are connected together front and back through the connecting plates to form the wing shape of the wing rib, each rib section is provided with a flexible connecting structure used for being flexibly connected with the adjacent rib section, and the flexible connecting structures can generate flexible telescopic deformation under the action of load to make relative rotation generated between every two adjacent rib sections; a flexible skin laid outside the variable camber wing rib, wherein the flexible skin and the variable camber wing rib can slide relatively; and a telescopic driver arranged between every two adjacent rib sections, wherein bending shape control over the trailing edge of the wing is achieved by controlling deflection of the rib sections. According tothe flexibly-deformable trailing edge variable camber wing rib structure, the multiple flexible telescopic drivers are distributed on the flexible deformation trailing edge variable camber wing rib structure, and the flexible skin with the out-of-plane rigidity is arranged on the wing rib, so that the trailing edge of the wing can generate great camber change, and the surface is smooth.

本申请提供了一种可柔性变形的后缘变弯度机翼，机翼包括：变弯度翼肋，包括多个肋节及连接板，相邻肋节之间通过连接板连接前后连接在一起构成翼肋的机翼外形，每个肋节具有用于与相邻肋节进行柔性连接的柔性连接结构，柔性连接结构受到载荷作用时能够产生柔性伸缩变形，使得相邻两个肋节之间产生相对转动；柔性蒙皮，敷设于变弯度翼肋外，且柔性蒙皮与变弯度翼肋之间能够相对滑动；伸缩式驱动器，设置在相邻两个肋节之间，通过控制肋节的偏转实现机翼后缘的弯曲形状控制。本申请通过在柔性变形后缘变弯度翼肋结构上分布式的布置多个柔性伸缩式驱动器，且在翼肋上布置具有面外刚度的柔性蒙皮，使得机翼后缘可以产生很大的弯度变化，且表面光顺。
