姿控发动机试验缓变参数数据修正方法

Data correction methods of slowly varying parameters in attitude control engine test

为了缩短型号试验周期,提高试验数据处理工作效率,结合姿控发动机试验缓变参数测试异常数据案例,开展了多种数据修正方法的应用效果研究,给出了数据修正方法的机理、应用条件及效果。经试验验证该方法效果显著,能够真实反映产品特性,为姿控发动机试验缓变数据处理领域提供了一套完善的异常数据修正方法。

In order to shorten the model test period and improve the efficiency of test data process- ing, the application effect of several data correction methods is carried out in this paper based on the ab- normal examples of slowly varying parameters in the attitude control engine test. The mechanism, applica- tion condition and efficiency about the data correction method are also given in this paper. The experimen- tal results show that the method is effective and can reflect the product characteristics, and can provide a complete set of abnormal data correction measures for the data processing field of slowly varying parame- ters in attitude control engine test.
