Abstract: An airfoil mimicking owl wings is used to determine the noise generation mechanism of silent owl. The flow field around the bionic airfoil suggests two noise sources caused by the leading-edge separation, one is the reattached turbulent boundary and the other one is the vortex shedding detached from leading-edge bubble. The reason for owl wing noise in low Reynolds number is the interaction between the turbulent boundary layer and the sharp trailing-edge of the bionic airfoil. Furthermore, as a promising means, the passive porosity technology is applied for the trailing-edge noise reduction of the airfoil. The static pressure fields around the airfoil verify that the porous trailing-edge can alleviate pressure change by the suppression of the vortex shedding and the damping of broadband turbulent boundary layer fluctuation. The relevant noise spectrum also indicates a pronounced noise reduction potential in excess of 10 dB, but in dependence on the flow resistivity. The findings of this study may be used as reference in the design of silent aircraft.

Key words: engineering bionics, bionic airfoil, vortex shedding, turbulent boundary layer, porous treatment, trailing edge noise reduction
