考虑敏捷性的过失速机动优化研究

建立了考虑敏捷性的过失速机动优化模型 ,取飞机的滚转、俯仰转动角速度为控制变量 ,代替了传统的以迎角、速度矢滚转角为控制变量的优化方法 ,使得优化的结果能在一定程度上反映飞机的敏捷性。用罚函数处理约束条件 ,用共轭梯度法对飞机的最短时间 1 80°航向转弯进行了寻优计算 ,优化结果接近于六自由度仿真结果

Optimal Post-Stall Maneuvers in Counting Aglity

The optimal post stall maneuver model is put forward which can take aircraft agility into account.In this model,the angle of attack and velocity bank angle are substituted by body roll rate and body pitch rate as controls,this leads to a measurable effect of agility.A numerical procedure on optimization of minimal time,180 deg reversal of the velocity vector maneuver is then established,in which a punishment function is defined to handle the constraints,and the conjugate gradient method is employed to search for the optimal solution,the results are similar to six freedom simulation.
