摘　　要：为了探索出一条适合于评估失速迎角前大迎角飞行品质评估的思路 ,通过选取推杆并改变1 0°姿态角 ,带过载的从一侧到另一侧的倾斜并截获 90°滚转角及空 -空跟踪三项任务作为子任务集 ,在一台地面飞行模拟器上对一架第三代战斗机大迎角飞行品质进行了评估 ,并把评估结果与通过等效系统方法得到的结果进行了对比 ,结果表明尽管大迎角品质边界相对于小迎角有所不同 ,但只要适当调整品质边界 ,则用于评估小迎角品质的方法如等效系统等 。In order to explore how to evaluate the high attack(AOA) flying qualities before stall AOA, through pushing stick and changing posture angle by 10°, to roll from bank to bank and to capture 90° roll angle and air to air tracking are chosen as a subset to study flying qualities at high angle of attak. Secondly, flying qualities of a third generation fighter are evaluated with a simulator. At last, the results of simulation evaluation are compared with ones derived from equivalent system method. The conclusion is that if the boundary of flying qualities are adjusted suitably, the high AOA flying qualities can still be evaluated by equivalent system method, although the boundary of high AOA flying qualities is different from small AOA ones.
