摘要
为研究导弹打击引起的方向舵卡死对飞机执行任务能力的影响,提出了一种基于航程的任务放弃杀伤判定方法.考虑方向舵卡死引起的纵横向气动耦合,论述飞机配平过程;基于受损飞机配平解,计算剩余飞行航程;根据任务剖面确定航程阈值,对比飞机剩余航程与阈值判定是否造成任务放弃杀伤.设置仿真算例,求解不同卡死角下飞机的航程损失,验证了所提任务放弃判定方法的可行性.研究结果表明,小角度卡死引起的航程损失较小,随着卡死角度增大航程损失迅速增加并最终导致任务放弃杀伤,且航程损失能够高达50%.
To study the effect of rudder jam caused by missile strike on the ability of an aircraft to perform missions,a method to judge mission abort kill based on flight range was proposed.The aircraft trim process was discussed with the vertical and horizontal aerodynamic coupling caused by the rudder jam taken into consideration.The remaining flight range was calculated based on the trim solution of the damaged aircraft.The range threshold was calculated according to the flight mission profile,and it was compared with the remaining range to judge mission abort kill.Simulation examples were set and range losses of aircraft under different jammed angles were calculated,verifying the feasibility of the proposed method for judging mission abort kill.Results show that range loss caused by a small-angle jam is short.As the angle jam increases,the range loss increases rapidly and eventually leads to mission abort kill,and the range loss can reach 50%.
