The features of drag reduction of the representative pigeon in fluid medium were studied. It was found that the flight capability of the pigeon mainly depends upon the distinct sequential array of its high lift wing feathers. Quantify the geometric information about the leading edge shape of the pigeon wing

bionic models were built in which the trailing edge shape was defined by wavelength and wavecrest to wavetrough amplitude. The finite volume method and the pressure corrected SIMPLEC algorithm were used to simulate numerically the aerodynamic performance of the bionic airfoil model. The results show that at the condition of deep stall

the bionic airfoil model can improve significantly the aeroperformance

reduce aerodynamic drag by 9.1%.
