Abstract

Abstract

This article reports Ignition and Growth equations of aluminized explosives containing oxidizer (RDX/AP/Al/HTPB=20/43/25/12). VLW EOS (equations of state) is applied to calculate the parameters of JWL EOS for this explosives. The free-surface velocities of the metal plate and the interface particle velocities between the explosive and sodium chloride window were recorded by the VISAR velocity interferometer. We have performed 3D numerical simulation for the particle velocities test to evaluate the parameters of the reactive rate EOS. The results show that the VLW EOS method and the explosion/widow interface velocity can be used to determine the JWL EOS and the reactive rate EOS. The results of metal plate acceleration test agree well with calculations.
