基于飞参数据的飞行仿真模型验证

摘要

The lack of the support of empirical data has been an obstacle to the search for effective quantitative measurements to validate the simulation model of flight simulators. The author propose FDR system data as a potential model validation measurement. The method was proved feasible by introducing and analyzing of the sources, usage and characteristics of the FDR system data. The model validation system based on FDR data was designed and developed, which the basic structure and composition were introduced, and the method of solving the difficulties and key issues of the validation system were raised. The validity of the model validation system based on FDR data was proved by experimentation. The system is essential to enhancing the fidelity of flight simulator..%由于缺少真实数据的支持,飞行模拟器飞行仿真模型的验证一直缺乏有效的量化验证测试手段.针对这一现实难题,提出使用飞参数据进行模型验证的方法.通过介绍和分析飞参数据的来源、用途和特点,论证了该方法的可行性.设计和开发了飞参自动验模系统,介绍了其基本原理和结构组成,并对其中的难点和关键问题进行了深入研究分析,阐述了解决问题的思路和方法.试验结果验证了飞参验模系统的正确性和有效性,对提高飞行模拟器逼真度具有积极意义.
