摘要：
Videorecording was used to measure the velocities of expansion of detonation products (DPs) in the axial and radial directions during the detonation of phlegmatized RDX (PRDX) and its mixtures with ASD-4 aluminum powder (PRDXA). It was demonstrated that the initial particle velocities of the DPs in the axial and radial direction for PRDXA are 1–2 km/s higher than those for PRDX for expansion into an atmospheric-pressure air medium and 0.5–2.0 km/s lower for expansion into a low-pressure (10 kPa) air medium. The result of this can be explained by the rapid reaction of aluminum particles during the turbulent mixing of DPs with air due to the formation of cumulative microjets at the surface of the charge.
