The invention discloses a bionic wing. The bionic wing comprises a wing main body, a bionic sawtooth front edge structure and a bionic comb-shaped rear edge structure, the bionic sawtooth front edge structure is arranged on the front edge of a wing main body and comprises a plurality of triangular sawteeth, and the triangular sawteeth are arranged in the spanwise direction of the front edge of the wing main body; the bionic comb-shaped trailing edge structure is arranged on the trailing edge of the wing main body, the bionic comb-shaped trailing edge structure comprises a plurality of comb teeth, the comb teeth are arranged in the spanwise direction of the trailing edge of the wing main body, each comb tooth is provided with an inner groove channel, and the inner groove channels extend inwards from the ends of the comb teeth; the bionic sawtooth front edge structure and the bionic comb-shaped rear edge structure both belong to feather bionic structure characteristics of an owl, so that the feather bionic characteristics of the owl are combined with the wing main body, the airflow separation noise is inhibited through the bionic sawtooth front edge structure, and the vortex shedding strength is weakened through the bionic comb-shaped rear edge structure; the aerodynamic noise is obviously reduced while the high aerodynamic efficiency of the wing main body is kept.

    本发明公开了一种仿生机翼,包括机翼主体、仿生锯齿前缘结构和仿生梳状后缘结构;该仿生锯齿前缘结构设于机翼主体的前缘,仿生锯齿前缘结构包括多个三角形锯齿,多个三角形锯齿沿机翼主体的前缘展向排列布置;该仿生梳状后缘结构设于机翼主体的后缘,仿生梳状后缘结构包括多个梳齿,多个梳齿沿机翼主体的后缘展向排列布置,多个梳齿上均设有内凹槽道,内凹槽道从梳齿的端部往内延伸布置;而仿生锯齿前缘结构和仿生梳状后缘结构均属于猫头鹰的羽毛仿生结构特征,所以本发明将猫头鹰羽毛仿生特征与机翼主体相结合,通过仿生锯齿前缘结构抑制气流分离噪声,仿生梳状后缘结构削弱涡脱落强度,在保持机翼主体高气动效率的同时,显著降低气动噪声。
