摘　　要：该文依据惯导飞行阶段控制指令的生成原理,通过建立零漂对惯导陀螺外框轴偏转角度的数学模型,利用末制导炮弹全弹道刚体运动模型,根据仿真计算结果,分析了惯导陀螺零漂对末制导炮弹弹道性能的影响特点。得出了惯导陀螺定向轴纵向零漂对射程、侧向零漂对弹道侧偏有重要影响的结论,对新型末制导炮弹研制过程中的惯导陀螺零漂控制以及末制导炮弹射表的编拟有重要的理论指导价值。According to the generating principle of control orders during inertial guide flight stage,this paper establishes a mathematical model of deflection angle of external frame axis of inertial guide gyro.Simulation results are obtained by a rigid motion model of terminal guide shell.The characteristics of the influence of zero drift of inertial guide gyro on trajectory of terminal guide shell are analysed.It is concluded that the effects of vertical zero drift of the rotor axis on the range and the transverse zero drift on the yaw are remarkable.This conclusion has important theoretical instruction value for inertial guide gyro zero drift control and making firing table of a new terminal guide shell.
