| 摘 要： | 本文采用数值计算方法,计算了实验段截面为扁八角形的低、亚音速风洞中的侧滑薄机翼的气动特性及洞壁干扰修正量。 基于流谱观察实验,对带有后退侧缘的翼段用两种极端的气动模型来描述。计算结果表明,就自由流态的气动特性而言,两者的平均值与文4]中的实验结果相符,而相应的洞壁干扰修正量,也与本文的实验结果相近。

| Abstract: | Anumerical method is presented to calculate the aerodynamic- charac-ferisics and wind tunnel interference corrections for a sideslipping thin wing in a low-subsonic wind tunnel with a flat octagonal test section.Based on experimental observations, with two extreme aerody-namic models to describe the wing section of the backward sideedge, the average value obtained agrees-well with the test data from reference 4] in .free flows. The calculated interference corrections are in harmony with our experimental results. |
