The invention relates to the technical field of wing structures, in particular to a variable-trailing-edge wing rib structure which comprises a leading edge section, a middle edge section and a trailing edge section. Comprising a front edge section which is provided with a plurality of holes; a mounting groove is formed in the middle edge section, and a driver with a pneumatic rope is mounted in the mounting groove; the rear edge section comprises a plurality of rigid units and a plurality of flexible units, and the rigid units and the flexible units are alternately arranged; the tail end of the middle edge section is used as a first rigid unit of the rear edge section, and the tail end of the rear edge section is also a rigid unit; a bolt hole is formed in the groove of the middle edge section and used for fixing a driver, a round hole is formed in the other end of the middle edge section, and the pneumatic rope head end penetrates through the rigid units and the flexible units in an opposite mode through the round hole and is fixed to the rigid unit at the tail end. The rigid unit of the wing rib rear edge section is of a driven structure and is driven by deformation of the flexible unit to deform. The deformation amount of the deformation unit is controlled through the action of the pneumatic rope traction driver, and self-adaptive continuous camber changing of the trailing edge of the wing can be achieved.
本发明涉及机翼结构技术领域,特别涉及一种可变后缘的翼肋结构,包括前缘段、中缘段及后缘段;包括前缘段,上设置有多个开孔;中缘段,上设置有安装凹槽,该安装凹槽内安装有带有气动绳的驱动器;后缘段,包括多个刚性单元与多个柔性单元,多个刚性单元与多个柔性单元交替设置;中缘段的尾端作为后缘段的首个刚性单元,后缘段尾端同为刚性单元;中缘段凹槽内设置有螺栓孔用于固定驱动器,另一端设置有圆孔,气动绳头端经由圆孔,对穿各个刚性单元与柔性单元,固定在尾端的刚性单元上;翼肋后缘段的刚性单元为从动结构,由柔性单元的变形带动其变形。本发明通过气动绳牵引驱动器的作用控制变形单元的变形量,可以实现机翼后缘自适应连续变弯度。
