Equation of state for the detonation products of hexanitrostilbene at various charge densities

Abstract

An extensive description of the detonation behavior for the unique and useful high explosive hexanitrostilbene (HNS) is presented. To accomplish this the necessary experimental results measured by detonation of the pure material at charge densities of 1.00, 1.20, 1.40, 1.60, and 1.65 (g/cm/sup 3/ = Mg/m/sup 3/) were compiled and evaluated. Estimates of the equation of state of the detonation products were made for each charge density. To confirm these estimates two-dimensional hydrodynamic (HEMP code) calculations to simulate the cylinder test experiments for two charge densities of 1.2 and 1.6 Mg/m/sup 3/ were carried out. Detailed comparisons of the calculational and experimental results were made for these two tests. Interpolation and extrapolation of the equation of state parameters provided final estimates for the other charge densities. The results are summarized in five sets of Chapman-Jouguet parameters and JWL equation of state coefficients.
