The invention provides a bird-feather-imitating one-way valve wing structure which comprises a feather shaft, a plurality of feather branches, a branch assembly and a swing assembly, the feather branches are symmetrically arranged on the two sides of the feather shaft, and a plurality of barb feather small branches and a plurality of groove feather small branches between every two adjacent feather branches are connected in a one-to-one correspondence mode. The swing assembly comprises a plurality of barb feather branchlet valves and a plurality of groove feather branchlet valves, under the condition that the bird feather imitating one-way valve wing structure is in a first state, every two adjacent barb feather branchlet valves are arranged in an overlapped mode, every two adjacent groove feather branchlet valves are arranged in an overlapped mode, and under the condition that the bird feather imitating one-way valve wing structure is in a second state, every two adjacent groove feather branchlet valves are arranged in an overlapped mode. A gap is reserved between every two adjacent barb feather branchlet valves, and a gap is reserved between every two adjacent groove feather branchlet valves. According to the bird feather imitating one-way valve wing structure provided by the invention, the downward flapping lift force of the wings during flight of the aircraft is improved, and meanwhile, the upward lifting resistance of the wings is effectively reduced, so that the flight efficiency of the aircraft is improved.

    本发明提供一种仿鸟羽单向阀翅膀结构,包括:羽轴、多个羽枝、分支组件及摆动组件,多个羽枝对称设于羽轴的两侧,相邻的两个羽枝之间的多个倒钩羽小枝和多个沟槽羽小枝一一对应连接,摆动组件包括多个倒钩羽小枝瓣膜和多个沟槽羽小枝瓣膜,在仿鸟羽单向阀翅膀结构处于第一状态的情况下,相邻的两个倒钩羽小枝瓣膜叠合布置,相邻的两个沟槽羽小枝瓣膜叠合布置,在仿鸟羽单向阀翅膀结构处于第二状态的情况下,相邻的两个倒钩羽小枝瓣膜之间留有间隙,相邻的两个沟槽羽小枝瓣膜之间留有间隙。本发明提供的仿鸟羽单向阀翅膀结构,在提高飞行器飞行时的翅膀向下扑翼的升力的同时,有效的降低了翅膀向上抬翼的阻力,从而提高了飞行器的飞行效率。
