通过实验研究了热降解对不锈钢药室内几种高密度塑料粘结炸药冲击感度和爆轰增长的影响。组件在轻气炮的靶室内就地加热。改变了限制条件，以便在某些情况下允许炸药的热膨胀，在另一些情况下允许释放分解气体。在LiF窗口界面用VISAR测量了粒子速度分布。对于IHE PBX-9502的结果表明，其对冲击起爆的敏感度可以根据加热过程中的约束条件而显著增加或降低。对PBX-9404和PBX-9501的影响要小得多。
The authors have performed experiments to study the effect of thermal degradation on shock sensitivity and growth to detonation of several high-density plastic bonded explosives, confined in stainless steel cells. Assemblies were heated in situ in the target chamber of a light-gas gun. Confinement was varied to allow, in some cases, for thermal expansion of the explosive, and in other cases to vent the decomposition gases. Particle velocity profiles were measured using VISAR at a LiF window interface. Results for the IHE PBX-9502 showed that its sensitivity to shock initiation could be dramatically increased or decreased depending on the confinement conditions during heating. Effects were much less pronounced for PBX-9404 and PBX-9501.
