Correlation between critical parameters of detonation determining detonation wave propagation limits

Detonability is one of the most important characteristics of high explosives. One of the main parameters for its estimation is to determine the limiting possibilities of propagation of the detonation wave. Depending on the method used, the detonation wave propagation limits can be determined under various conditions (acoustic stiffness of the surrounding material and geometry of the explosive charge, which determines the presence or the absence of “overdrive” of the detonation wave, a velocity gradient, “dark” zones, etc.) that affect the numerical value of the result. As a result of comparative analysis of experimental data, for several plastic high explosives (based on RDX, nanostructured RDX, TEN, and BTF), relationships were determined that provide the ability to recalculate the values of the characteristics of detonability obtained by only one of the experimental methods for conditions implemented in other methods. It was shown that such calculated estimates give numerical values of these characteristics with accuracy up to the error of the experiment. The results provide a broad experimental basis for comparing estimates of the detonability of explosives obtained by different methods, taking into account the characteristics of each method.
