Abstract
A method for studying the propelling effect of explosion products of condensed explosives is proposed and substantiated by calculations. This effect allows for a wide range of states on the isentrope of explosion products: from pressures and densities in the range of the Chapman-Jouguet state to a pressure of ≈0.1 GPa and a density of ≈0.2 g/cm3. This method is applied to perform experimental studies of the propelling effect of TG 25/75 explosion products, in which information on the movement of thin aluminum liners is recorded by a PDV multichannel heterodyne-interferometer.
