利用30 mm 口径火炮发射装有PTFE/A1活性材料芯体的弹丸,对炮目距离固定的无防护油箱和10、20、30 mm的不同厚度装甲板靶后防护油箱进行射击.结果表明,侵彻无钢靶防护的0.8 mm厚空油箱及满油油箱无法有效激活活性材料芯体;在油箱前加装装甲板后,弹体内活性材料被激活,并且随着装甲板厚度的增大,活性材料被激活的越充分,但是弹丸穿靶后轴向剩余速度也随之降低;防护装甲板厚度在20 mm左右时,活性材料对油箱的毁伤效应和引燃效果最佳.本研究分析了活性材料弹丸侵彻油箱毁伤增强效应,揭示了活性材料弹丸对油箱目标的毁伤机理,对活性材料研究和小口径活性侵爆弹结构设计有一定参考价值.
Experimental study on the damage effect of small caliber active explosives on fuel tanks
A 30 mm caliber artillery platform is used to fire a projectile equipped with a PTFE/Al reactive material core,and the unprotected fuel tank with a fixed distance from the gun target and the 10,20,30 mm armor steel target rear protection tank with different thicknesses are fired.The test results show that the core of the reactive material cannot be effectively activated by penetrating the 0.8 mm thick empty fuel tank and the full fuel tank without steel target protection;After the armored steel target is installed in front of the fuel tank,the reactive material in the projectile body can be activated,and with the increase of the thickness of the armored steel target,the more fully the reactive material is activated,but the axial residual velocity behind the projectile target also decreases;When the thickness of the protective armor is about 20 mm,the damage effect and ignition effect of the reactive material on the fuel tank are the best.In this study,the effect of reactive material projectiles penetrating the fuel tank was analyzed,and the damage mechanism of the reactive material projectiles to the fuel tank targets was revealed,which has certain reference value for the study of reactive materials and the structural design of small-caliber reactive Penetrating and exploding projectiles.
