“…11, the calculated and experimental density distributions along the charge axis are compared for various fixed values of the radius. Distributions along this coordinate appear in the solutions of one-dimensional problems used to estimate the parameters of expanding detonation product [18][19][20]. The data in Fig.…”

This paper gives a description of a high-speed X-ray tomographic technique and the results of its application to finding the density distribution of detonation products of condensed explosives from measurements using synchrotron radiation. The data obtained for a cylindrical charge of pressed TNT of diameter 12.5-mm and density 1.6 g/cm 3 are compared with the results of solution of the corresponding gas-dynamic problem of steady-state detonation. The experimental and computational results are in satisfactory qualitative and quantitative agreement. The features of the employed technique and the distribution obtained are analyzed. The technique as a whole and the results obtained can be used to test and refine the known equations of state for detonation products and to construct new ones.

The complex problem of the propagation of explosion of condensed explosives in gas media (air) is solved analytically. A generalized model is constructed which describes the following processes: explosion propagation in an explosive charge from the time of initiation to the establishment of the normal detonation regime (explosion transient); proper normal detonation; expansion of explosion products into the medium (air) with the formation of a blast wave and motion of the perturbed medium in the blast wave. Unlike in the well-known formulations of such problems using the classical hypothesis about adiabatic explosive processes, the present study is based on the more natural hypothesis about an exponential density profile of the perturbed medium and explosion products. The method of Salamakhin is extended to real explosion processes.
