The invention discloses a novel method for determining parameters of a deformable wing rib, and belongs to the field of flexible structure design of morphing airplanes, the deformable wing rib realizes chordwise deformation through a flexible structure, the flexible structure is positioned between a front beam and a rear beam of a wing and is formed by connecting a plurality of jujube-pit-shaped unit cell structures in series, and a supporting guide beam is arranged in the middle to support and guide the flexible structure. The front and rear ends of the flexible structure are respectively connected with the front and rear end connecting plates and then are connected to wing front and rear beam webs through the front and rear end connecting plates. The front and rear end connecting plates support the supporting plates at the two ends of the flexible structure and connect the wing front and rear beam webs with the flexible structure. The requirements for in-plane deformation capacity and out-of-plane bearing capacity of the deformable wing rib can be met, meanwhile, uniform supporting and effective connection of the longitudinal ribs of the flexible skin are achieved, and it is guaranteed that the flexible skin is evenly stressed.

    本发明公开了一种新型的可变形翼肋参数确定方法,属于变体飞机柔性结构设计领域,该可变形翼肋通过柔性结构实现弦向变形,柔性结构位于机翼前、后梁之间,由多个枣核形单胞结构串联组成,中间设置支撑导向梁对柔性结构起到支撑导向作用。柔性结构前后端分别与前后端连接板连接,再通过前后端连接板连接在机翼前后梁腹板上。前后端连接板一方面对柔性结构两端支撑板起到支撑作用,另一方面将机翼前后梁腹板和柔性结构相连接。本发明能实现可变形翼肋面内变形能力和面外承载能力的需求,同时实现对柔性蒙皮纵向筋条的均匀支撑和有效连接,保证柔性蒙皮受力均匀。
