摘要
对飞机环控系统引气分系统的动态性能进行了试验研究 .主要研究了在不同流量和温度值的引气量的冲击下系统的温度响应 ,以及引气流量突变时系统的温度响应和引气压力变化时系统的压力响应 .试验结果表明 :系统的压力响应时间在 1s内 ,而系统的温度响应在 1 0～ 3 0s之间 .
The experimental results are reported about the pressure transient responses and temperature transient responses of the bleed system of an aircraft environmental control system when the bleed air flows, pressure and temperature are varied. Results show that the pressure response of the bleed system is quite fast and response time is within 1 second, and on the other hand, the temperature response time is 10～30 seconds.
