Luminescence of a Front of Low Detonation Speed in Nitro-Glycerine

摘要

This report is a study of the low detonation speed in nitroglycerine with high speed photography. Low speed conditions were carried out in cylindrical charges of nitroglycerine with the help of an intermediate charge of sodatol through a thin plexiglas plate. The detonation front is disturbed in materials where the speed of sound is less than 2.0 km/sec. The detonation front is stable in materials where the speed of sound is greater than 2.0 km/sec. The mechanism of propagation in the stable wave was found to be a concave wave profile relative to the direction of propagation.
