在对舰载机复飞操纵策略研究时,由于升降舵容易受到外部环境的影响,使得在复飞过程中升降舵参数发生较大的随机性突变,造成系统操纵精度差。采用传统的操纵策略方法,遇到突变时只通过加入约束条件来固定参数进行操纵,没有考虑加入的约束条件对复飞性能的影响,导致复飞的安全性差的问题,提出升降舵参数优化的复飞区优化操纵策略。将升降舵操纵通过复飞区优化准则进行参数化,使得舰载机在复飞机动过程中,满足复飞最短距离,在融合航母舰尾高度最高的性能指标,并限制迎角不超过失速迎角,进行待定参数值的计算,实现复飞区优化操纵策略。仿真结果证明,改进联合复飞区优化操纵策略明显地缩小了复飞边界区,大大提高了着舰和复飞的安全性。
The elevator in carrier aircraft wave-off landing is easily affected by external environments,which leads to random mutation of elevator parameters.Then it results in poor precision of system operation.Traditional method fixes parameters to operate only via introducing constraint condition in mutation.It does not consider the influence on wave-off properties of constraint condition.So it leads to safety problem.In this paper,a manipulation strategy is proposed based on optimizing elevator parameters.The elevator operation is parameterized via optimization rule of wave-off area.It satisfies the shortest distance in the progress of carrier aircraft wave-off.Then the highest performance index of carrier stern is integrated.Undetermined parameter value is calculated to realize the optimization strategy via restricting attack angle less than stall attack angle.The simulation results show that the modified manipulation strategy shrinks wave-off boundary regions obviously.It improves the safety of landing and wave-off apparently.
