摘要:
为了获得温压炸药装药量对近地空中爆炸的能量输出结构的影响规律，开展了质量为0.5、1.0、2.0 kg的温压炸药近地空爆试验，并使用压力传感器、高速摄像机、红外热成像仪记录了爆炸冲击波和爆炸火球参数。使用TNT超压经验公式对0.5、1.0、2.0 kg装药的空中入射冲击波、地面冲击波的超压峰值进行拟合，建立了冲击波超压峰值衰减规律方程。根据高速摄像机和红外热成像仪的测试结果，建立了基于装药量的爆炸火球直径、火球持续时间和火球温度最高时刻热通量的拟合方程。对比0.5、1.0、2.0 kg装药的爆炸火球图像和温度曲线可以看出：随着装药量的增加，爆炸火球的最高温度、火球尺寸（直径×高度）以及持续时间均有一定的增加，高温区域在火球面积中的占比也有所提升。
Abstract:
In order to obtain the influence law of charge amount on the energy output structure of thermobaric explosives in the near ground air explosions, the near-ground air explosion test of the thermobaric explosive with a mass of 0.5, 1.0, and 2.0 kg was carried out. Parameters of explosion shock wave and fireball were recorded using pressure sensors, high-speed cameras, and infrared thermal imagers. The TNT overpressure empirical formula was used to fit the peak overpressure of the shock wave in the air or on the ground after the explosion of 0.5, 1.0, and 2.0 kg charges, and the equation for the attenuation law of the peak overpressure of the shock wave was established. According to the test and analysis results of the high-speed camera and the infrared thermal imager, fitting equations for the diameter, duration, and heat flux at the highest temperature moment of the explosion fireball based on the charge amount were established. Comparing the images and temperature curves of 0.5, 1.0, and 2.0 kg explosion fireballs, it can be seen that， as the charge amount increases, the highest temperature, the size (diameter × height), and the duration of the fireball have all increased to a certain extent, and the proportion of high-temperature areas in the fireball area has also increased.
