Abstract

Because the random states of the projectile explosion position relative to the intersection target, the dispersion characteristics of warhead fragments are inconsistent, and it is difficult to provide a scientific calculation model of the target damage of warhead fragments formed by projectile proximity explosions. This paper studies a testing method of the projectiles explosive position using a combination of six screen sensors and an area array camera. We set up a calculation model of the projectile proximity explosion position parameters, which establishes the proximity explosion area probability of the projectile hitting the target. The calculation method of the target damage condition probability under the condition of firing multiple projectiles in one test was researched according to the dispersion characteristics of projectile proximity explosion, the damage area of the target, and the intersection condition of the projectile and the target. We also establish a target damage probability calculation model under the condition of an effective projectile proximity explosion hitting the target. The experimental results show that the target damage results of a theoretical simulation calculation and an actual projectile proximity explosion test data calculation were basically consistent. Moreover, the proposed target damage calculation model was verified under the probability of multiple projectile proximity explosions hitting the target.

Summary

Introduction

The hit probability of a projectile fired by artillery is an important indicator for evaluating the development level and combat capability of a weapon system [1], [2]. From the test principle and model, it can be seen that the damage effect of the projectile proximity on the target mainly depends on the dispersion position of the warhead fragments formed by the projectile explosion in the target.
