面向飞行模拟机自动客观测试的飞行仿真辅助验证方法

Flight Simulation Assisted Validation Method for Automatic Objective Test of Flight Simulator

摘要:

在完成飞行动力学模型开发后，由于试飞数据误差与建模误差的影响，飞行模拟机自动客观测试的仿真数据与试飞数据的测试验证结果往往难以完全满足模拟机鉴定规章要求。为了进一步改善测试验证结果，首先根据测试科目的飞行动力学特性及其考察目的，将适航鉴定规章中的客观测试科目归纳为三类；其次，针对需要采用辅助验证的科目，制定测试科目的辅助验证策略；然后，基于形成的策略建立 PID 辅助验证系统，最终形成面向飞行模拟机自动客观测试的飞行仿真辅助验证方法。通过某型民用飞机飞行仿真算例，对比验证辅助验证方法的有效性。结果表明：本文提出的方法能够有效改善仿真数据与试飞数据的测试验证效果，有助于满足适航法规的客观测试容差要求。

Abstract:

After the completion of flight dynamics modeling, due to the impact of flight test data error and modeling error, the comparison results between automatic objective test simulation data and flight test data are often difficult to fully meet the requirements of simulator evaluation regulations. In order to further improve the test and verification results, the subjects in the airworthiness certification regulations are classified into three categories according to the flight dynamics characteristics of maneover and the purpose of the investigation of the subjects. Secondly, for the subjects that need to adopt assisted validation, the assisted validation strategy of test subjects is developed. Then, based on the formed strategy, a P-I-D assisted validation system is established. Finally, a flight simulation assisted validation method for automatic objective test of flight simulator is established. Through a flight simulation example of a civil aircraft, the effectiveness of the assisted validation method is compared and verified. The results show that the assisted validation method can effectively improve the test validation effect of simulation data and flight test data, and help meet the tolerance requirements of airworthiness regulations.
