The invention discloses a novel deformable wing rib, which belongs to the field of morphing aircraft structure design, and is characterized in that the novel deformable wing rib comprises a front end connecting plate and a rear end connecting plate, a flexible structure and a support guide beam are arranged between the front end connecting plate and the rear end connecting plate, the flexible structure is a deformation area of the deformable wing rib, and the flexible structure generates uniform deformation; a wing front beam web plate and a wing rear beam web plate are respectively arranged on two outer sides of the front end connecting plate and the rear end connecting plate; the flexible structure is formed by connecting and expanding a plurality of jujube-pit-shaped unit cell structures in series, and each jujube-pit-shaped unit cell structure is composed of two flexible plates; flexible plates at the front end and the rear end of the flexible structure are respectively connected with a front end connecting plate and a rear end connecting plate; the chord-length-variable wing rib structure capable of being deformed in the chord direction is formed by connecting the jujube-pit-shaped unit cell structures in series, the chord length of the wing can be evenly changed, and meanwhile the flexible skin can be evenly supported.
本发明公开了一种新型的可变形翼肋,属于变体飞机结构设计领域,其特征在于,包括前端连接板、后端连接板,所述的前端连接板、后端连接板之间为柔性结构和支撑导向梁,柔性结构为可变形翼肋的变形区域,柔性结构产生均匀的变形;所述的前端连接板、后端连接板两外侧分别为机翼前梁腹板、机翼后梁腹板;所述的柔性结构由多个枣核形单胞结构串联扩展而成,所述的枣核形单胞结构由两片柔性板组成;柔性结构前后两端的柔性板上分别连接前端连接板、后端连接板;本发明采用枣核形单胞结构串联构成了可弦向变形的变弦长翼肋结构,可以实现机翼弦长均匀变化,同时实现对柔性蒙皮的均匀支撑。
