The work recommends the use of booster explosives in explosive trains and also looks at decreasing the vulnerability of the booster explosives in practical use. The results show that when the density of PBXN-5 explosive is about 80% theoretical maximum density (TMD), the reaction is violent. When the densities are from 91.5% to 80.0% TMD, the severity of reaction is stronger. When the density is about 75.0% TMD, the charge just deflagrates. When the density is about 93.0% TMD, the pressure burst occurs. The response times of reaction could be delayed by using high-strength shells.
