摘　　要：借鉴美国对运载火箭爆炸模式的分类,结合以往火箭爆炸事故情况,对某型火箭爆炸模式进行分类。根据能量相似原理将推进剂总量换算成TNT炸药当量,对某型火箭在不同爆炸模式下的TNT当量进行估算。介绍了不同组合的液体推进剂爆炸、液体火箭不同失效模式爆炸两种TNT当量系数估算方法,并对不同爆炸模式的TNT当量进行了定量计算。通过计算,得出危害性最大的两种爆炸事故模式:火箭在发射架上发生完全爆炸包括由任一级爆炸并发的殉爆以及火箭在飞行过程中某一时刻发生较为完全的爆炸。In order to analyze liquid fuel rocket explosion mode accurately and estimate the proper explosion equivalent,the paper classified the some rocket explosion according to the American rocket explosion mode categories and the situations of the past rocket explosion accidents.We estimated the TNT equivalent in different explosion modes by transform of propellant gross for some rocket using the similar energy theory.There are two estimate methods for TNT equivalent coefficients which are different combinations liquid propellant explosion and different invalid modes explosion.By these two methods,we get the TNT equivalent coefficients of different explosion modes.From the calculating results,we can get the most two harmful explosion modes which are full explosion happens in the launcher by any stage and full explosion happens during the flying process.
