Changes of sidewall sweep Angle and cowl position can influence inlet performance such as mass capture, total pressure recovery coefficient and uniformity of isolator exit flow field.

侧板后掠角大小和整流罩位置变化时，对进气道的质量捕获、总压恢复系数和隔离段出口流场的均匀性等都有一定的影响。

There exist a close coupling relation between the wind tunnel flow field parameters, total pressure and Mach number.

风洞流场参数—总压、马赫数之间存在严重的耦合关系。

Hence, the method of vortex control is available for removing swirl, decreasing total pressure loss, and improving flow field in S-shaped intake.

因此，抽气形式的有源涡控是抑制旋流、减少出口总压平均损失、改善S弯进气道出口流场的有效措施。
