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

For the purpose of analyzing the influence of velocity deviation and flight path angle deviation of the missileļ¼‡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.
