Abstract: The long-eared digital wing model was divided to several cross sections. Camber line and thickness distribution of every profile were extracted based on section theory. The least square method was used to fit the coefficients of the camber line and the thickness distribution, and the coefficients were averaged to decrease discrepancy. The three dimensional model of the owl wing was established by adjusting the maximum camber and thickness, the chord length and the position of the leading edge in spanwise direction. The study provided preliminary basis for simulating to explore the excellent aero performance and acoustical behavior of the long-eared wing, and which can be applied to the bionic flying robot.

Key words: engineering bionics, long-eared owl wing, three-dimensional geometry structuring, least square method
