摘要: 本文采用超音速线化理论,算出斜板侧缘附近干扰区内的流场,并根据流量积分方法,导出了关于流量系数的侧向溢流公式。本文还根据Busemann锥型流理论,应用Carafoli方法,得出了估算侧后掠端板影响的方法和图线。理论计算结果与现有的实验数据作了比较,符合程度很好。

Abstract: Based on supersonic linearized theory, the flow field in the region near the side-edge of the ramp is calculated, and then a formula of mass flow ratio of side-spillage is derived by the use of the technique of mass flow integral. Using Carafoli's method on the basis of Busema-nn's conical flow theory, the method and the computing curves for predicting the effects of sweepback side-plate are given.Comparison between the results of theoretical calculation and available experimental data shows the agreements are satisfactory.
