Experimental Study on Shock Initiation of Simulative Warhead by Energetic Kill Element

为提高战斗部的毁伤效能,对氟聚物基含能反应材料进行了研究。对氟聚物基含能材料配方改进并制备了一种Φ26mm×60mm的含能毁伤元。将含能毁伤元装入特定结构壳体后进行了冲击引爆模拟战斗部试验。采用高速录像观察含能毁伤元冲击侵彻模拟战斗部后的爆炸情况并测试爆炸后空气冲击波超压。考察了含能毁伤元不同速度下对B炸药和PBX-9404炸药的引燃引爆能力。设置了B炸药模拟战斗部静爆试验作为对比。在试验的基础上,通过测量爆炸后空气冲击波超压进行了TNT当量等效对比分析。试验研究表明,在735m·s^(-1)的侵彻速度下,氟聚物基含能毁伤元可冲击引爆B炸药模拟战斗部。在962m·s^(-1)的侵彻速度下,能引发PBX-9404炸药模拟战斗部爆燃反应。

To improve the damage efficiency of warhead,the fluorine polymer based energetic reactive materials were studied.The formulation of the fluorine polymer based energetic material was improved and a kind of energetic kill element with dimension ofΦ26mm×60mm was prepared.Experimental study on shock Initiation of simulative warhead was carried out,in which the energetic kill element was confined by a shell with specific structure.The explosion situation after the energetic kill element penetrated into the warhead was observed by high-speed video and the air shock wave overpressure after explosion was measured.The ignition and blasting ability of the energetic kill element to detonate Comp.B and PBX-9404 under different speeds was examined.The static detonation test of Comp.B simulation warhead for comparison was set.Based on the test,through the measurement of air shock wave overpressure after explosion,the comparison and analysis of the equivalent TNT equivalent was performed.Experimental study show that under the penetration speed of 735m·s^-1,the energetic kill element can detonate the Comp.B warhead.Under the penetration speed of 962m·s^-1,the energetic kill element can arouse the Comp.B warhead deflagration.
