Flight Performance Verification of a Flight Simulator Based on Maximum Entropy Spectrum Estimation

将预处理后得到的动态飞行性能数据,用最大熵谱估计的方法进行一致性验证。首先分析最大熵谱估计的验证方法,然后以平飞加速过程中飞机的过载随速度变化曲线为例,采用最大熵谱估计的方法进行一致性检验。结果显示,该型飞行模拟器的仿真数据与飞机真实数据的一致性较好,该验证方法也适用于模拟器其他动态数据的一致性验证。

Verifies the dynamic flight performance data obtained after pretreatment by the maximum entropy spectrum estimation method. Firstly, analyzes the method of the maximum entropy spectrum estimation and then uses the maximum entropy spectrum estimation method for the consistency test. The results show that the simulation data of the flight simulator is better than that of the real data of the aircraft, which is also applicable to the consistency verification of other dynamic data of the simulator.
