COMPATIBILITY CHECK OF THE FLIGHT TEST DATA AND RECONSTRUCTION OF THE DATA

本文采用飞行器六自由度运动方程组,建立了飞行试验数据相容性检验的数学模型.应用最大似然估计求得测量数据的系统误差并进行数据重建。利用计入测量噪音的六自由度动力学方程组的仿真数据检查了方法的可行性和程序的正确性,最后处理各种飞行器的飞行试验数据,得到了满意的结果.

In this paper, the mathematical model of compatibility check of flight test date is set up based on the kinematic equations with six freedom of aircraft. By using the maximum likelihood method the system error of the measurement data can be obtained and the flight data can be reconstructed. The feasibility of the method and the correctness of the program have been checked using the simulation data calculated by six freedom kinematic equations in consideration of the measurement noice. Finally various flight test data are processed and the results are quite satisfactory.
