The unsteady-state combustion of a granulated solid propellant (GSP) in a cylindrical confined vessel with a uniformly perforated lateral surface is considered. The vessel is placed in a simulation chamber. The GSP specimens are heated by incandescent particles supplied by a hot gas flow through the left perforated face of the vessel. The right face of the vessel is either blank or perforated. The one-dimensional gasdynamic problem is solved by the method of large particles, with the solution of the Euler problem being modified. The one-dimensional thermal problem is solved for individual granules of the propellant in each gasdynamic unit. The behavior of the unsteady-state combustion of the GST affected by variations in the initial temperature and initial burning web of propellant granules as well as the mass and the number of granules in the tested volume has been analyzed numerically. The results of the analysis are reported.
