| 摘 要： | 针对某发动机交付试车检查高压导叶控制规律时,在转速上升和下降过程中出现导叶控制规律偏差大的情况,通过对高压导叶控制原理和试车数据分析,得出高压导叶控制系统负载力为影响偏差的主要因素。利用地面试验设备,采用对顶缸加载方式,开展负载力对导叶控制偏差影响试验,复现了发动机试车过程中控制规律偏差问题。试验结果表明:负载力越大,导叶控制偏差越大。

| Abstract: | When the control law of the high-pressure guide vane was checked for a certain engine delivery test run, the deviation of
the guide vane control law was large during the rising and falling of the rotating speed. Through the analysis of the control principle of the
high pressure guide vane and the test run data, it was concluded that the load force of the high pressure guide vane control system was the
main factor affecting the deviation. By using the ground test equipment and the loading mode of the top cylinder, the influence test of the
load force on the control deviation of the guide vane was carried out, and the problem of the deviation of the control law was reproduced
during the engine test run. The test results show that the greater the load force is, the greater the control deviation of the guide vane is. |
