摘要：

The detonation activity of aerosuspensions of particles of a secondary explosive (pentaerythritol tetranitrate) with a mean-volume density of 0.14-1.28 mg/cm3 at the initial pressure of the air in a shock tube of 0.01-0.3 MPa was considered. The dependence of the structure and the main parameters of the detonation wave in an explosive aerosuspension on the concentration of the explosive in it and the initial air pressure as well as the mechanism of propagation of this wave were investigated. The critical (lowest) mean-volume density of an explosive aerosuspension, at which its detonation is still possible, was determined experimentally for different initial air pressures. © 2014 Springer Science+Business Media New York.
