摘要
一种计算高速风洞腹部支架对模型纵横向气动力干扰量的工程方法，可以非常方便地分析腹支的位置、厚度、后掠角等几何参数对干扰量的影响。与支架干扰实验结果的比较表叨，本方法可以用作为选择腹支位置及几何外形参数的理论工具。
An engineering method for computing the ventral strutinterferences on the longitudinal and lateral aerodynamic characteristicsof models in high speed wind tunnel tests is presented in this paper.It isconvenient to analyze effects of geometric parameters of the strut,such aslocation, thickness, swept angle, and so on, on the corrections.Comparisonsof computational results with wind tunnel test data show that the presentmethod can be used as a theoretical tool for choosing the location andgeometric configuration of the strut.
