The conditions for the appearance of a plateau-like region called pseudo-ideal detonation in the dependence of the velocity of detonation (VOD) of composite explosives on the diameter of a charge were considered. A theoretical model of steady-state non-ideal detonation with a slightly curved front and a two-stage mechanism of chemical reaction was used for analysis. The calculations were performed for a trinitrotoluene-50% ammonium nitrate mixture and a mechanically activated ammonium perchlorate-20% aluminum mixture. The coefficients of the equations describing the global chemical conversion rates of components were fitted in the calculations. In both cases, the dependence of the VOD on the diameter of the reciprocal charge with a plateau-like region was obtained for an increasing conversion rate of the major explosive (trinitrotoluene and ammonium perchlorate, respectively).
