摘要
本文对二维跨声速洞壁干扰修正的壁压法——FFT 法和匹配法进行了改进;两个算例的计算结果显示了这两种改进方法的有效性。文中还给出了 NAC∧0012翼型和DSMA523超临界翼型的 FL-21风洞试验数据洞壁干扰修正结果。
FFT method and Match method for two-dimensionaltransonic wall interference corrections have been improved in this pa-per.The computational results of two examples show that the impro-vements are effective,The corrections for test data of NACA0012 air-foil and DSMA523 supercritical airfoil in FL-21 wind tunnel are alsopresented.
