Abstract
The results of an experimental study of the detonation characteristics of the C25A model explosive composition manufactured at the V.V. Bakhirev State Research Institute of Machine Building (GosNIIMash) are presented. The following detonation parameters were determined: density, detonation velocity, pressure, and chemical spike duration; pressure, temperature, density, mass velocity, speed of sound, and the adiabatic index at the Chapman-Jouguet point. The onset time of the aluminum oxidation reaction after the passage of the detonation wave and the response time during the expansion of the explosion products in the detonation flow were estimated, and an adiabatic curve for the unloading of the detonation products was constructed. Equipment from the Lavrentyev Institute of Hydrodynamics and the Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences was used in the study.
