摘要
以放宽静稳定性(RSS)战斗机F-16为例,讨论了深失速走廊特性。利用具有非线性气动力的简化运动方程,分析了飞机深失速特性;应用反向积分技术确定出了深失速走廊——深失速平衡点的收敛区域(ROC)。并分别对开环俯仰拉起和带过载滚转中惯性耦合引起的深失速进行了分析。最后阐述了一种改出深失速的非线性开关控制律。
In this paper a relaxed static stability (RSS) fighter F16 is taken as an example to discuss deep stall corridor characteristics.Simplified equations of motion with nonlinear aerodynamics are utilized for aircraft deep stall analysis. The deep stall corridor,which means the region of convergence(ROC)of the deep stall trim point,is constructed by means of backward integration techniques.The analysis is performed for deep stall entries due to open loop pitch pull up and inertia coupling during loaded rolls.Finally a nonlinear switching control law for deep stall recovery is described.
