Płaski rozlot produktów detonacji ze skokowo zmiennym wykładnikiem izentropy

The problem has been solved explicitly of the expansion of gaseous products of the plane detonation, on consideration of jump-variations in the value of the isentropic exponent k. The reaction of the atmospheric air that surrounds the explosive has also been taken into account. Closed-form formulae have been derived for the parameters of state and motion of the expanding post-explosion gases. These formulae can be applied in engineering practice, for instance, when assessing the effect of tamping upon the pressure-pulse of the post-explosion gases in a cylindrical shot-hole. They also permit the losses to be assessed of energy released from the explosive while blasting with no tamping.
