一次引爆型云爆剂的爆速计算

Computation on Detonation Velocity of Single Event FAE

以典型一次引爆型云爆剂为基础,根据炸药的热化学理论和爆轰理论,对一次引爆型云爆剂的爆速进行了理论分析和计算,并研究了组分配比及配方对爆速的影响。结果表明,一次引爆型云爆剂的理论爆速与金属粉含量有关,在一定范围内适当增加金属粉含量,可以提高爆速,且金属粉的热值越高,其一次引爆型云爆剂理论爆速也越高。

On the basis of classic single event FAE （Fuel-Air Explosive）, theoretical analysis and computation to detonation velocity of single event FAE are carried out according to thermochemistry theory and detonation theory of explosive. The influence of mixture ratio and formulation of components on detonation velocity is studied. The results show that theoretical detonation velocity of single event FAE correlates with the content of metal powder, and its detonation velocity can be increased while increasing the content of metal powder to some extent. Higher the thermal value of metal powder, higher the theoretical detonation velocity of single event FAE.
