Claim 1:
2. The air vehicle with the double-layer rotor wing structure according to claim 1, wherein the structure of the lower-layer rotor wing (7) is identical to the upper-layer rotor wing (6); wherein an upper side plane of the lower-layer rotor wing is a turbulent flow airfoil (20), and a lower side plane is a flap airfoil (21); wherein the turbulent flow airfoil (20) is formed by connecting a front curved surface with a rear smooth surface; wherein the front curved surface of the turbulent flow airfoil (20) protrudes upwards relative to a rotation plane of the rotor wing;
and wherein the turbulent flow airfoil (20) and the flap airfoil (21) are of an asymmetric structure on a longitudinal projection plane.
