Abstract:
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.
