A Method for Self-correcting Acting Time of the Electronic Time Fuze

摘要

Aiming at solving the problem of burst point disaggregation caused by projectile muzzle velocity deviations,a method for self-correcting acting time of the electronic time fuze is proposed.The fuze acting time is directly corrected by analyzing the relationship between the changes of acting time and the variations of muzzle velocity.Take 105mm tank shell as an example,the acting time of the electronic time fuze is modified by this method.The simulation result shows that the revised acting time is at least ten times more accurate than the former one,and when the setting time is equal to ten seconds and the muzzle velocity decreases 13m/s,the projectile range error will reduce from 85m to 4m using primary polynomial fitting method to correct the time.The feasibility and high accuracy of this method is thus proved.To sum up,this method is of great significance in improving precision of burst point of electronic time fuze.
