Abstract

Experimental results on the regularities of the change in the critical combustion thickness as a function of the compaction coefficient and the thickness of the inert envelope are presented. In accordance with existing views, it is established empirically that the product of the critical combustion thickness, the adiabatic rate, and a linear function of density is constant. Exact expressions are obtained for the characteristic equation of the fourth degree and for the temperature of the combustion front of the double-layer system of gasless mixture—inert plate, which, for limiting cases, coincide with solutions of Ya. B. Zel'dovich and G. P. Ivleva, A. G. Merzhanov, and B. V. Shkadinskii.
