| 摘 要： | 针对涡扇发动机工作特点,设计了一种发动机喘振信号判定方法。以大量发动机试车数据和飞行试验数据为依据,采用一种新的判别方法来判定发动机工作状态。结合飞行器的综合控制系统,可以以最小的代价来实现发动机退出喘振工况。该方法充分考虑了工程应用的特点,具有很低的漏报率和虚报率。发动机地面试验验证和飞行器的飞行试验验证结果表明,该方法工作可靠。 |

| Abstract: | Aimed at special characteristic of turbofan engine , a surge signal judge method has been designed . Based on the test data from engine test-bed and flight-test, a special judge method for surge status has been used. Combined with aero-craft integration control system , this method can be used to exceed surge status by the minimum pricement. It has such feature as easy for use, and the fail-to-report-rating and decreased false-report-rating. The test results both from test-bed and flight test have shown that the method is reliable on operation. |
