Abstract

Abstract

The author improved the method of appending roughness,and by silk-screen method appended the specific space roughness to the leading-edge of swept wing.This technique has been successful in introducing specific wavelength disturbance into the boundary layer,and improves the artificial abduction wavelength precision.The single disturbance evolution was investigated by using sublimation technique in the low-turbulence wind tumel of NWPU,and its evolution trend is consistent with the calculation results.
