Density Distribution at the Detonation Front of Cylindrical Charges of Small Diameter

摘要

A synchrotron radiation based technique is use to study the density distribution at the detonation front and its neighborhood for condensed explosives.Particular data are obtained on the structure of the detonation front in TNT,RDX,and an alloy of TNT with RDX;a comparison of the data with those obtained using different techniques confirms the correctness of the technique.It is concluded that adequate information on the structure of the chemical-reaction zone can be obtained for charges of small diameter.At the same time,it is shown that the Chapman-Jouguet parameters for such charges are far from their predicted values for an infinite medium.The results of the work,including those on the curvature of the detonation front in charges of small diameter,supplement the existing knowledge of the detonation transformation in condensed explosives.
