The mathematical model and method of calculating the unsteady propagation of a convective flame front in cylindrical channels in solid fuel proposed in this paper take into account friction and interphase heat and mass transfer. The penetration of combustion into the channel comprises the process of ignition of the entrance zone exposed to the hot reaction products flowing into the channel and the propagation of the combustion front. The results of the calculations show that the channel surface is ignited by the flow of shocked gas. The presence of an ignition lag affects the distance from the shock wave to the ignition point, but has no significant influence on the propagation velocity of the front.
