Abstract:
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.
