Abstract:

A simple one-dimensional physical model of explosive burning under confinement is assumed and used as a basis for calculations of a the rate of pressure increase behind the plane of deflagration b the time and the distance necessary to start a shock in the solid explosive. The pressure increase, approximately exponential in time, compares rather well with experimental results. The calculated distance of incipient shock formation is about 12 cm. This results supports the hypothesis that transition from slow burning to detonation is due to a shock, which arises spontaneously in a confined burning medium.
