    摘要:

    为实现全含能侵彻战斗部毁伤威力的有效评价,基于125 mm火炮建立了全含能战斗部毁伤威力表征试验系统,从侵彻扩孔、高温高压、纵火引燃等多个方面对战斗部毁伤威力进行了多物理场信息描述。结果表明,16 kg战斗部在952 m·s-1速度条件下侵彻5层钢靶能够形成强烈火光,持续时间约120 ms,最大扩散范围超6 m×10 m,最高温度约2100 ℃,相比于惰性战斗部,温度增益约1270 ℃,1.2 m处的超压增益约为0.16~0.5 MPa,对5层钢靶破孔面积的累计增益达到300%以上,对油箱燃油有良好的纵火引燃效果。

    Abstract:

    To achieve an effective evaluation of the damage power of all-energetic penetration warhead, a test system for damage power assessment was established based on the 125mm artillery, accompany by a description in multiple physical fields from various aspects such as penetration, reaming, high temperature, high pressure, and arson ignition by arson. Results show that a 16 kg warhead can penetrate a 5-layered steel target at a speed of 952 m·s-1 to form strong fire which lasts for about 120 ms, with a maximum diffusion range of over 6 m×10 m and a maximum temperature of about 2100 ℃. Compared with the inert warhead, the gains of temperature and overpressure at 1.2 m are about 1270 ℃ and 0.16-0.5MPa, respectively, and the cumulative gain of the broken hole area of 5-layered steel target reaches beyond 300%. Moreover, the warhead has a good arson ignition effect on the fuel tank.
