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 dynamic performance of air-entrainment subsystem of aircraft environmental control system is studied experimentally.The temperature response of the system under the impact of the air bleed volume with different flow and temperature values and the temperature response of the system and the bleed air The pressure response of the system under pressure changes.The experimental results show that the pressure response time of the system is within 1 second and the temperature response of the system is between 10 and 30 seconds.
