摘　　要：在分析横航向飞行品质评估准则和方法的基础上,利用等效系统法对某型先进战斗机进行了横航向等效系统拟配,在时域、频域内验证了拟配结果。按照美军现行的M IL-STD-1797A规范对该型飞机横航向飞行品质做出了评估,重点分析了操纵系统中反馈通道对横航向飞行品质的影响。研究结果对带电传操纵系统的第三代飞机的作战使用与飞行品质潜能的发挥有一定的参考价值。Lateral and directional flying qualities of “military specification-flying qualities of piloted vehicles（MIL-STD-1797A）” issued by air force of the United States were studied. Equivalent system matching was used to match a fighter dynamics with that of a low-order equivalent system, and the results were validated in time-domain and frequency-domain. Lateral and directional flying qualities of the fighter was evaluated in term of the qualities specification, and the affections of flying qualities from feedback channel in the control system were analyzed especially.
