The invention provides a fishbone-imitated flexible trailing edge variable camber wing. The fishbone-imitated flexible trailing edge variable camber wing comprises a wing body, a middle wing box and a flexible trailing edge section which are connected in sequence, after a plurality of groups of rigid fishbone joints are connected in series and hinged, the tail ends are hinged with the rear edge rigid wingtips to form a fishbone-like structure; the ends of the adjacent rigid fishbone joints are connected through a composite material flexible corrugated plate, and a micro-groove wing skin is bonded to the outermost layer of the fishbone-imitated flexible trailing edge variable camber wing; the driving device comprises a double-shaft driving motor and a carbon steel ladle aluminum rope, the double-shaft driving motor is fixed to the side, close to the wing body, of the middle wing box, the carbon steel ladle aluminum rope is arranged in the rigid fishbone joint and the rear edge rigid wingtip in a penetrating mode, and the two ends of the carbon steel ladle aluminum rope are wound on two driving shafts of the double-shaft driving motor respectively. According to the fishbone-imitated flexible trailing edge variable camber wing, landing and approach noise caused by gaps can be reduced, and the mechanical structure can be simplified, so that the overall performance of an aircraft is effectively improved.

    本发明提供一种仿鱼骨柔性后缘变弯度机翼,包括顺次连接的机翼本体、中间翼盒和柔性后缘段;多组刚性鱼骨骨节串联铰接后尾端与后缘刚性翼尖铰接形成仿鱼骨结构;相邻刚性鱼骨骨节端部之间通过复合材料柔性波纹板连接,所述仿鱼骨柔性后缘变弯度机翼最外层粘结有微沟槽机翼蒙皮;驱动装置包括双轴驱动电机和碳钢包铝绳索,双轴驱动电机固定在中间翼盒靠近机翼本体的一侧,碳钢包铝绳索穿设在刚性鱼骨骨节和后缘刚性翼尖中,碳钢包铝绳索两端分别缠绕在双轴驱动电机的两个驱动轴上。本发明仿鱼骨柔性后缘变弯度机翼能减少由于缝隙导致的着陆和进场噪声,并且能够简化机械结构,从而有效提高飞机的整体性能。
