针对弹体侵彻过程中弹道偏转现象,开展了降低弹体弹道偏转效应研究。设计了一种锥形结构实验弹体,对其侵彻混凝土靶板过程中受力情况进行了分析,锥形结构弹体侧壁力矩有助于降低弹体侵彻过程的弹道偏转程度;采用130mm轻气炮开展了锥形实验弹体侵彻混凝土靶板实验,并与普通直杆形弹体侵彻结果进行了对比。实验结果表明,锥形弹体侵彻弹道的偏转程度小于普通直杆形弹体,锥形弹体在斜侵彻以及高速侵彻厚目标情况下,将有更好的侵彻性能。

The study of reduction of trajectory deflexion was conducted in this paper. Based on dynamic mechanics analysis of projectile and concrete target during impact, a cone-shaped projectile was designed to block trajectory deflexion of projectile by parietal moment generated in penetration. The penetration experiments of the cone-shaped and the traditional penetrators into concrete target were carried out with 130 mm light gas gun. The results show that trajectory deflexion of cone-shaped penetrators are smaller than that of traditional ones. The cone-shaped penetrator is suitable for oblique penetration and penetration into thick targets at high speed.
