RÉSUMÉ

This paper presents the results of an investigation of binary mixtures of nitromethane as a detonability liquid with the addition of the nonexplosive liquid ingredients methanol and nitrobenzene. An electromagnetic method for the registration of the particle velocity profile was applied. The record of detonation wave profiles with typical von Neumann spike enabled the determination of the Chapman-Jouguet state and the definition of a sufficient set of detonation characteristics. The detonation product pressure dependencies relative to the concentration of nonexplosive ingredients were obtained. The differences in the natures of the diluents became apparent in the degree of reduction of the detonation parameters when the percentage of nonexplosive liquid was increased. Some disagreements with the one-dimensional hydrodynamic detonation theory were noted.
