HMX含量对PBT基推进剂撞击感度和非冲击点火反应特性的影响
Influences of HMX Content on the Impact Sensitivity and Non-Shock Initiation Reaction Characteristics of PBT Based Propellants
摘要
Abstract
In order to investigate the effect of HMX content on the impact sensitivity and non-shock initiation reaction characteristics of PBT based propellants,BAM impact sensitivity tests,friability tests and Susan tests were carried out.The experimental results show that with the increase of HMX content,the characteristic drop height of PBT based propellants at 50％explosion probability(H50)decreases,indicating that the impact sensitivity increases with higher HMX content.In friability tests,the critical non-shock initiation velocities for the PBT based propellants with the HMX mass fraction of 0,5％,10％,and 15％are 168,147,136,and 131 m/s,respectively,showing a decline in the critical non-shock initiation velocity as HMX content rises.In Susan tests,four different kinds of PBT based propellants react as explosion or partial detonation at velocities range of 120 m/s to 300 m/s.The PBT based propellant with the HMX mass fraction of 10％exhibits more intense reactions compared to the other three PBT based propellants at the same velocity.关键词
