JP-10燃料燃爆特性及无约束爆炸状态场参数试验研究

Experimental Study on Explosion Characteristics and Unconfined Blast Parameters of JP-10 Fuel

以云爆武器的液态燃料组分筛选为应用背景,基于JP-10燃料密度高、综合性能佳以及成本低等特点,开展了爆轰管内JP-10燃料的燃爆特性试验研究以及外场无约束空间下JP-10燃料的分散效果及爆炸状态场研究。研究发现:在强起爆作用下,JP-10燃料爆轰管内的爆炸超压约为0.6 MPa;在无约束条件下,JP-10燃料抛撒爆炸过程中,其云雾区内超压峰值要高于同体积的乙醚燃料,且爆炸温度峰值达到1 366.9℃,1 000℃以上高温持续时间是乙醚燃料的2倍,说明JP-10燃料的高热值特性有利于提高云爆武器的热毁伤效果。

JP-10 has features of high fuel density, good comprehensive performance and low cost. Based on the background of FAE weapons, especially on the screening of liquid fuels, experiments were carried out to study the explosion characteristics of JP-10 fuel in self-designed detonation tube, as well as the blast parameters in unconfined space. Experimental results show that the peak value of blast overpressure for JP-10 fuel in shock tube is 0.6 MPa. In unconfined space, the blast overpressure in cloud zone for JP-10 fuel is higher than diethyl ether, meanwhile the high temperature duration(over 1 000 ℃) is twice of diethyl ether with a peak value of 1 366.9 ℃. The data obtained indicates that JP-10 fuel, with its high colorific value, will enhance the thermal damage effect of FAE weapons.
