Gas Transport in the Insensitive High Explosive PBX 9502 Open
Small‐scale laboratory experiments were performed to analyze gas transport mechanics in PBX 9502, an insensitive high explosive (IHE) composition. Two independent investigations are reported here. First, gas permeametry and dynamic pycnome…
