摘要
通过活动基座模拟器试验 ,研究了飞机稳定裕度判据 ,并与低阶等效系统拟配法及人 -机闭环准则进行了比较。试验结果表明 ,飞机稳定裕度判据较等效系统法对飞机飞行品质提出了更高的要求 ,能够对飞机 /飞控系统组合体的操纵品质作综合评定 ,且与人 -机闭环准则有较好的一致性 ,适用于现代高性能战斗机纵向机动特性评定。
A flying quality evaluation method——aircraft stability margin criterion is presented and verified with the simulator test data of an advanced combat.The definition, limiting boundary, and computation process is discussed.The results of this method are compared to those from the low order equivalent system matching and Neal Smith criterion. It is concluded, that the aircraft stability margin criterion can comprehensively evaluate the longitudinal maneuvering characteristic of airplane, and show good correlation to the Neal Smith criterion. So it can be applied to find the flying quality defects that may result in the PIO tendency.
