Влияние бора на параметры горения ВЭМ и окисление нанопорошков Al/B, Ti/B

Влияние бора на параметры горения ВЭМ и окисление нанопорошков Al/B, Ti/B

Abstract

Представлены результаты термодинамического расчета влияния содержания бора на параметры горения высокоэнергетического материала (ВЭМ) на основе перхлората аммония, бутадиенового каучука, порошка алюминия и титана, а также данные термического анализа нанопорошков Al, Ti и механосмесей Al/В, Ti/B. Получены значения температуры горения, удельного импульса и массовой концентрации конденсированных продуктов сгорания ВЭМ в зависимости от соотношения содержания металла и бора. Установлено, что с увеличением концентрации бора в составе ВЭМ, содержащем Al, температура горения и удельный импульс снижаются на 16 и 3.3% соответственно, в то время как для состава ВЭМ, содержащего Ti, удельный импульс возрастает на 7.7% при соотношении компонентов Ti/B = 20/80. Проведенный термический анализ нанопорошков металлов в воздухе показал, что значение максимальной скорости окисления Al/В и Ti/B растет при увеличении содержания бора в механосмеси.
