Abstract

Abstract

Via self-designed detonation tube, the detonation characteristics of hydrocarbon fuels were studied, and the conditions of low temperature and vacuum were considered. After systematic experiments, the relationship between detonation characteristics and ambient conditions were obtained and compared with that of normal condition. The results showed that the influence of the initial pressure played a more important role than the initial temperature, and when the initial pressure decreased to half of the barometric pressure, the detonation of hydrocarbon fuel was in critical condition. The achievements will be a complement and support the prediction of weapon performance for fuel-air explosives.
