摘　　要：由于超高温射孔弹的地面测试的条件较实际工况条件存在较大差异,因此地面测试穿深性能并不能真实反映射孔弹在高温高压条件下的穿深水平。通过利用高温高压试验装置在不同温度压力条件下,开展89HNS型超高温射孔弹穿靶试验,研究了温度、压力、时间对超高温射孔弹穿深性能的影响。结果表明,温度升高对射孔弹穿深性能的影响较为有限,而压力升高会对穿深性能造成较大影响,在高温高压条件下射孔弹的穿深性能与地面测试存在巨大差异。There is large difference between the actual working condition and ground test conditions of ultrahigh temperature charge,so the ground testing penetration performance cannot really reflect the charge under the condition of high temperature and high pressure in penetration.In this paper,through the use of high temperature and high pressure test device in different temperature and pressure conditions,we conduct ultrahigh temperature charge target test penetration,and study the temperature,pressure,time effect on the properties of ultra-high temperature charge.Results show that the temperature effect on the properties of charge penetration is relatively limited,the pressure may cause great influence on the penetration performance,and there is a huge difference of perforating charge penetration performance between test under the condition of high temperature,high pressure and that in the ground test.
