破片与冲击波对巡航导弹燃油舱毁伤实验研究

为提高导弹对抗生存能力和拦截弹药摧毁来袭导弹的毁伤概率,进行了巡航导弹的易损性和毁伤效应研究.在建立巡航导弹燃油舱模拟等效靶的基础上,利用模拟战斗部对其进行了距离冲击毁伤作用实验.结果表明:其毁伤模式主要是冲击引燃和机械毁伤;对于燃油舱,在爆轰产物流场作用区域以外,被6个以上的直径6.35 mm、速度1 850 m·s~(-1)的钢球命中,且破孔密度为1 224.5 m~(-2)以上时,才可被冲击引燃;对于燃油管,在爆轰产物流场作用区域以外,被3个以上的直径6.35 mm、速度1 850 m·s~(-1)的钢球命中,且破孔线密度为30 m~(-1)以上时,才可被冲击引燃;当交会角度不大于60°且命中破片的累积比冲量不小于325.5 Ns·m~(-2)时,可造成燃油舱内部结构破坏,燃油舱功能丧失;当交会角度不大于60°且命中破片的累积比冲量不小于765 Ns·m~(-2)时,可造成燃油舱壳体大变形、开裂解体.

Experimental Investigation on Damage to Fuel Tank of Cruise Missile by Fragments and Shock Waves

To improve the antagonizing viability of the missile and the lethality probability for heading off ammunition to destroy the arriving attacking missile, the vulnerability and lethality of the cruise missile is studied in this paper. On the basis of establishing the simulative equivalent target of the fuel tank of the cruise missile, the impact damage experiments are carried out by simulative warheads. The result shows that: the damage modes of the cruise missile fuel tank are mainly the impact ignition and the mechanical damage. The fuel tank can be ignited while it is impacted by more than 6 steel balls with the diameters of 6.35 mm at a speed of 1 850 m·s~(-1) outside the detonation flow field action area, and the perforation surface density of distribution is more than 1 224.5 holes per square meter. The fuel ripe can be ignited while it is impacted by more than 3 steel balls with the diameters of 6.35 mm at a speed of 1 850 m·s~(-1) outside the detonation flow field action area, and in the meantime, the perforation line density of distribution is more than 30 holes on per meter of length. When the crossing angle is less than 60°, and the accumulated specific impulse of the striking fragments is not less than 325.5 Ns·m~(-2) , the internal structure of the fuel tank can be damaged, which causes the loss of function of the fuel tank. When the crossing angle is less than 60°, and the accumulated specific impulse of the striking fragments is not less than 765 Ns·m~(-2) , the big distortion and crack can appear in the shell of the fuel tank, which causes the disintegration of the fuel tank.
