摘要

摘要: 为提高防空战斗部的毁伤后效，设计一种新型离散杆战斗部—中心起爆式变截面异形杆战斗部，并首次开展了爆轰驱动异形杆静态抛撒实验研究，获得了杆条的初速度，分析了杆条的抛撒特性、飞行姿态及其对目标钢板的侵彻效应。实验结果表明，异形杆在爆轰驱动过程中飞行姿态发生改变，达到了预期设计效果，提高了对目标的侵彻能力。

Abstract: A new discrete rod warhead named profiled rod warhead was proposed to improve the damage aftereffect, and the experimental research on detonation-driven profiled rod dispersing was employed. The initial velocity of the rods were obtained. The dispersion characteristics and flight attitude of the rods and their damage effect to the aming steel plates were analyzed. The flight attitudes of the rods changed in the detonation-driven process. Experimental results show that the expected design effects were achieved.
