The invention discloses a design method of a wing type of a rotor wing of a micro-miniature type rotor wing UAV and a product, and the design method combines an efficient optimization algorithm basedon the agent model, a shape parameterization method based on the free deformation technique, a grid deformation method based on the radial basis function and an aerodynamic performance computing method based on the average Reynolds equation. Firstly, the design condition is determined, the incoming flow states, namely, the incoming flow Mach number, the Reynolds number and the angle of incidence,of the wing type are determined according to the main operation condition of a propeller and the radial position of the wing type on the blades; then the design index is determined; a lift-drag ratioas large as possible is obtained. According to the method, an Eppler 387 is taken as the datum wing type, the wing type whose whole curvature of the upper surface protrudes upward, front section of the curvature of the lower surface is concaved downward and rear section protrudes upward is designed, the relative thickness is small, the upper surface of the rear section is relatively flat, the whole curvature is large, the front section of the lower surface is concaved remarkably, the wing type has low total resistance coefficient and high lift coefficient, and accordingly the wing type has high lift-drag ratio and the aerodynamic efficiency is improved.
