Abstract

Проведены эксперименты по исследованию неустойчивости детонационных волн в смесях нитрометана, тетранитрометана и ФИФО с инертными разбавителями посредством регистрации свечения детонационного фронта скоростной восьмиканальной шестнадцатикадровой электронно-оптической камерой НАНОГЕЙТ-22/16. В области неустойчивости детонации зарегистрировано неоднородное свечение детонационного фронта, которое связывается с турбулентным течением в зоне реакции. Формирование ячеистых структур с реакцией взрывчатого вещества в косых и поперечных волнах в исследованных составах не наблюдалось. Experiments are conducted to study the instability of detonation waves in mixtures of nitromethane, tetranitromethane, and FIFO with inert diluents by recording the detonation front glow with a NANOGATE-22/16 high-speed eight-channel sixteen-frame electron-optical camera. In the detonation instability region, the detonation front exhibits a nonuniform glow, which is associated with a turbulent flow in the reaction region. The formation of cellular structures with the reaction of the explosive in oblique and transverse waves is not observed in the compositions studied.
