真空环境下铝含量对HMX基炸药爆炸场压力和温度的影响
Effect of Al Content on the Explosion Fild Pressure and Temperature of HMX-based Explosive in Vacuum Environment
摘要
Abstract
To investigate the effect of Al powder content on the explosion reaction mechanism of HMX based aluminized explosive in vacuum environment ,the explosion field pressure and temperature of four kinds of aluminized explosives of alu -minum mass fraction as 15% (OA1) ,20% (OA2) ,25% (OA3) and 30% (OA4) were measured in a sealed explosion cham-ber ,and explosion gas products of explosive were collected and analyzed .The results show that the quasi-static pressure value decreases in the order of OA2 > OA1 > OA3 > OA4 ,meaning that explosive OA2 has the greatest explosion power . The equilibrium temperature of explosion field decreases in the order of OA 4 > OA3 > OA2 > OA1 ,indicating that the e-quilibrium temperature increases with the increase of aluminum content in the explosive .The first peak temperature of the four explosivesase decreases in the order of OA 1 > OA2 > OA3 > OA4 .For the time required to the first peak temperature , explosive OA1 and OA2 are far faster than explosive OA3 and OA4 .Except explosive OA1 ,other three explosives appear the secondary peak .The part of aluminum in the explosive of aluminum mass fraction as 15% and 20% are reacted in ad-vance .The reaction ratio of Al powder decreases in the orde of OA1 > OA2 > OA3 > OA4 ,indicating that with the increase of aluminum powder content ,the completeness of Al powder reaction decreases .关键词
