摘　　要：针对伸缩式变形飞行器制导问题,提出了一种考虑禁飞区规避的变形飞行器制导方法。以一种采用伸缩式机翼的飞行器为研究对象,将展长变形量作为制导指令,分析倾侧角、展长变形量和航程、高度之间的关系。基于参数化轨迹在线预测剩余航程,通过数值方法校正高度参数以满足终端约束,利用航向角走廊确定倾侧角符号。在线探明禁飞区时,设计变形策略以大升力外形横向机动规避禁飞区。仿真结果表明,该变形制导方法以单一高度参数校正纵向剖面,制导精度高,终端约束能力强,同时设计横向制导逻辑,充分利用大升力外形机动能力横向机动规避禁飞区,实现了变外形飞行器多约束绕飞。For the guidance problem of telescopic morphing aircraft,a guidance method considering nofly zone avoidance is proposed.Taking a telescopic morphing aircraft as the research object,the span deformation amount is used as a guidance command.The relationship among bank angle,span deformation amount,flight distance,and altitude is analyzed.The remaining flight distance is predicted online based on the parameterized trajectory,and the height parameter is corrected numerically to meet the terminal constraint.The bank angle symbol is determined by the heading angle corridor.When the no-fly zone is encountered online,a morphing strategy is designed to horizontally maneuver with high lift configuration to avoid the no-fly zone.The simulation results show that the morphing guidance method has high guidance accuracy,strong terminal constraint ability based on correcting single altitude parameter of longitudinal profile.The lateral guidance is designed to make full use of the maneuvering ability of the large lift form to avoid the no-fly zone and realize multi-constraint circling of morphing aircraft.
