These are compared with simulating plates of target contour, wind tunnel test data, high altitude test data. Good flow field quality is given for the typical engine.

将这些技术参数和图谱与模拟板的目标图谱数据、风洞吹风试验数据及高空台试验推算结果进行了综合分析与对比，较完整地表述了发动机进口的流场品质。

About the experiment, these experiments were conducted in the free stream wind tunnel, and vitiated air heater was used to simulate the high altitude flow condition.

本文试验在自由射流风洞中进行，利用空气加热器模拟高空飞行条件。
