再入点参数偏差对过载定延时引信误差研究

Error of Overload Setting Time Delay Fuse Caused by Trajectory Parameter Deviations of Reentry Point

为分析导弹再入点速度偏差和弹道倾角偏差对过载定延时引信爆高精度的影响,针对再入段的飞行特性,通过再入段弹道模型,分别分析实际弹道再入点速度、弹道倾角与标准弹道的偏差对过载定延时引信爆高精度的影响,仿真结果表明:弹道倾角偏差对过载定延时引信爆高精度影响较大,在实际飞行过程中传送再入点速度和弹道倾角时可有效减小过载定延时引信爆高误差。

For the purpose of analyzing the influence of velocity deviation and flight path angle deviation of the missile＇s reentry point upon the precision of overload setting time delay fuse height of burst, a model of reentry trajectory is built based on the flight characters of the reentry segment, and the velocity deviation and flight path angle deviation between virtual trajectory and standard trajectory and their influence on the precision of overload setting time delay fuse height of burst are analyzed. The simulation results show that the deviation of flight path angle is more influential on the fuse precision, and in real trajectory flight, the transmission of velocity and flight path angle of the reentry point can effectively reduce the error ofoverload setting time delay fuse height of burst.
