摘　　要：为了评价现代飞机的飞行品质特性,通常采用的方法是用一个低阶系统去等效拟配真实的高阶系统。本文根据MIL-HDBK-1797中提出的横航向低阶等效拟配模型,对某三代战斗机两种典型状态的横航向飞行品质进行分析。在拟配过程中,首先用一简化的荷兰滚航向低阶等效系统模型进行等效拟配,将拟配结果作为横航向全拟配等效模型的初值,计算结果表明该战斗机具有良好的横航向飞行品质;等效拟配系统具有很小的失配度,能够真实的反映出该型飞机的横航向品质特性。To assess the lateral and directional flying qualities, it is a widely acceptable method to match its dynamics with that of a low-order equivalent system. This paper analyses the fighter qualities at two typical states using a low-equivalent system presented by MIL-HDBK-1797. First of all, the iterative initial values that used by the low-equivalent system is acquired from a simple equivalent model, then the final values is acquired. The results indicate that the aircraft has excellent lateral and directional flying qualities, and the low-order equivalent which match the high-order real system has an acceptable tolerance.
