高空台压力测试系统气路延时分析

Analysis on Air Path Delay of Pressure Test System of High Altitude Platform

压力测试系统中管路延时对系统的测试时延有着重要影响。本文分析了高空台压力测试系统管路部分在理想状态下、考虑管路摩擦、热交换和管路变化几种状态下的气路延时，并将理论值与实验值进行了分析对比，得出了整个气路部分的延时范围。

The air path delay range in pressure test system is very important for the whole testing system .In this paper, the time delay range of air path of high altitude＇s pressure test system in the conditions of ideal state, pipeline friction, heat exchanging and pipeline variation is analyzed. And analyzing and comparing the theoretical value with the experimental value and obtained the delay range of the whole air paths.
