摘　　要：受油包线范围的确定对硬式空中加油的成功对接、安全加油具有重要意义。本文提出了一种不同干扰等级下受油机飞行边界数值认定方法。首先,通过解算KC-135加油机的硬管包线给出受油机的加油可行范围。其次,在分析受油机纵向及横侧向运动模型的基础上,设计受油机多模态双闭环控制系统,使受油机速度、姿态角、位置等状态量能够稳定保持。最后,通过对受油机各模态的数字仿真分析,探析不同干扰等级下的受油机飞行边界范围,并规定受油机飞行安全品质等级。结果表明,受油机在Ⅳ级干扰的环境下不再适合空中加油任务,这对空中加油试飞验证具有很强的指导意义。The receiver envelope range is very important for docking and refueling during boom air refueling.It is presented that a numerical identification method for the flight boundary of receiver under different interference levels.Firstly,by calculating the envelope of boom on KC-135,we give the feasible flight range of the receiver.Secondly,on the basis of analyzing the longitudinal and lateral motion models of the receiver,a multi-mode double closed-loop control system of the receiver is designed to keep the speed,attitude angle and position of the receiver stably.Finally,by digital simulation analysis of various modes of the receiver,the range of flight boundary of the receiver under different interference levels is analyzed and the flight safety quality level of the receiver is determined.The results show that the receiver is no longer suitable for the aerial refueling task under the interference level,which has a strong guiding significance for the aerial refueling flight test.
