Abstract: The values of the detonation velocity in thin layers of the VS-2 pyrotechnic composition are given. The Jones–Wilkins–Lee equation of state parameters of explosion products were determined. The obtained equation of state was used to perform numerical calculations and comparison with the experimental parameters of the air shock wave formed upon initiation of the VS-2 composition. Computational and experimental studies were carried out to determine the dependence of the pressure pulse on the thickness of the VS-2 layer. The dependence of the specific pressure pulse of the explosion products on the surface density of the VS-2 composition was determined.

Keywords: detonation velocity, Jones–Wilkins–Lee equation of state, numerical simulation, specific pulse.
