利用高速摄影和红外测温计,实测了伴有爆炸反应的FAE燃料扩散速度、半径及云雾的温度;分析表明:化学一次起爆FAE装置,燃料出壳体后2ms达最大运动速度。化学起爆和高速分散一次起爆试验装置燃料抛撒都具有较高的初始扩散速度,装置的结构参数对燃料扩散过程有较大影响。 The FAE fuel diffusion velocity, radius and cloud temperature with explosion reaction were measured by high-speed photography and infrared thermometer. The analysis showed that the chemical FAF device was detonated once, and the maximum velocity was reached 2 ms after the fuel came out of the shell. Both the chemical detonation and the high-speed dispersion primary detonation test device have a high initial diffusion rate of fuel, and the structural parameters of the device have a great influence on the fuel diffusion process.
