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。

Reducing the inlet temperature of cooling water and increasing its mass flow are favorable to increase refrigerant performance coefficient, and can decrease optimal pressure at high pressure side.

降低冷却水进口温度和提高其质量流量不仅有利于提高制冷性能系数，而且能降低最佳高压侧压力。
