Abstract

A special facility for investigating gaseous detonation was designed using a CCDS2000 computerized detonation-spraying complex to implement flow-through supply of the components of an explosive mixture and activation of deflagration-to-detonation transition in a long cylindrical channel. The detonation velocity and the cell size of the detonation front in mixtures of a composite fuel based on methyl acetylene and allene with oxygen were experimentally determined, and the concentration limits of steady-state detonation in a tube of 26 mm diameter were obtained. Detonation parameters were calculated and compared with experimental values. For comparison, the detonation of mixtures of acetylene and propane-butane with oxygen under similar conditions was studied.
