飞行试验是飞行器、发动机、机载设备、武器系统等在实际飞行条件下进行的各种试验,以及以飞行器为试验平台所实施的航空航天和其他领域的新概念、新理论、新技术的探索、研究、演示和验证试验,是进行相关学科研究、产品试验验证的重要手段和途径。为提高航空发动机飞行试验的安全性,科研人员在飞行试验数据的基础上,建立起各种发动机实时监控模型,并基于发动机参数的模型预测值与实测值确立监控残差,实现试飞过程的趋势监控。可在发动机出现异常时及时发出警告,并采取相应 Flight tests are all kinds of tests carried out under actual flight conditions of aircraft, engines, airborne equipment and weapon systems, as well as exploration of new concepts, new theories and new technologies in aerospace and other fields that are carried out by aircraft as test platforms , Research, demonstration and verification test, is an important means and means to carry out relevant discipline research, product testing. In order to improve the safety of aeroengine flight test, based on the flight test data, the researchers set up various real-time monitoring models of the engine and established monitoring residuals based on the predicted and measured values ​​of the engine parameters to achieve the trend of flight test monitor. In the event of anomalies in the engine promptly issued a warning, and take the appropriate
