| 摘 要： | 改进了添加粗糙带方法,使用丝网印刷方式在后掠机翼前缘添加特定间距的粗糙带.成功地在边界层内引入了特定波长的驻波,提高了人工诱导驻波波长精度.在西北工业大学低湍流度风洞中使用升华法研究了单一波长驻波的发展趋势,其扰动发展趋势与计算结果吻合得很好.

| 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. |
