The patterns of occurrence and propagation of low–velocity detonation (LVD) in ammonium perchlorate and its mixtures with polymethylmethacrylate and aluminum ASD-4 with a relative density of up to 0.98 in durable non-destructive shells when initiated from the blind end are determined. It is shown that the addition of polymethylmethacrylate to ammonium perchlorate facilitates the transition of burning to LVD. The influence of the size of the oxidizer particles, the diameter, and the structure of mixtures on the spread of LVD is revealed. It is established that the ignition and burning of aluminum in a mixture with 15% polymethylmethacrylate 75% ammonium perchlorate 10% ASD-4 with a porosity of 2% occurs ~ 6 microseconds after the passage of a shock wave through it.
