摘　　要：二次起爆型云爆战斗部的大面积体爆轰,与识别最优爆轰浓度下的多点子引信协同起爆有关。基于脉冲超声在云团中的回波反射系数衰减特性,研制云爆子引信原型样机,搭建基于火箭撬速度分别为75 m/s、100 m/s的子引信与等比云爆燃料抛撒云团的交会浓度探测试验平台。通过试验得到高速环境下子引信动态识别云团浓度的变化曲线,以及不同浓度下子引信脉冲超声衰减的梯度规律。结果表明:在不同交会速度下,该云爆子引信和试验方法能够获得云爆弹燃料抛撒云团的高速交会浓度识别,对设定标称浓度为75 g/m^(3)、150 g/m^(3)、225 g/m^(3)的计算误差不大于15%。The large-area detonation of the second-detonation fuel-air-explosive(FAE)warhead is related to the initiation control under the condition of optimal fuel cloud concentration when FAE cloud intersects with fuze at high speed.Based on the attenuation characteristics of the reflection coefficient of pulsed ultrasound in the cloud,a prototype of a FAE sub-fuze was developed,and a rocket sled test platform was built for detecting the intersection concentration of FAE cloud with the sub-fuze with rocket sled speeds of 75 m/s and 100 m/s.The curve of the sub-fuze dynamic recognition cloud concentration under high-speed environment and the gradient characteristics of pulse ultrasonic attenuation at different concentrations were obtained through test.The test results show that the proposed method can be used to obtain the high-speed intersection concentration identification of FAE cloud at the different speeds.The calculated error is not more than 15%at the nominal concentrations of 75 g/m^(3),150 g/m^(3) and 225 g/m^(3).
