在国内外研究液体推进剂爆炸火球生长规律的基础上[1 4 ,6] ,建立了火箭爆炸事故所形成的火球的生长规律、空气卷入量和N2 O4 富余量的数学模型。利用已有的蒸发理论[5] ,探讨了火箭发射事故毒源强度及其衰减的计算数学模型。文中所建的数学模型 ,其试算结果与曾发生过的火箭爆炸事故的火球照片和毒源强度基本匹配
Based on the study of the growth law of fireballs of liquid propellants at home and abroad [1, 4, 6], the mathematical model of fireball growth law, volume of air entrainment and N2 O4 margin was established. Based on the existing evaporation theory [5], the computational mathematical model of the intensity and decay of the source of rocket launchers is discussed. The mathematical model built in this paper is basically consistent with the calculated results of the fireball photos and the strength of poison source of the rocket explosion accidents that have occurred
