Ignition process of granular propellant charge in gun propellant system is the essential step in the whole interior ballistic cycle and igniter is the very important element of ignition system. The task of igniter is to give propellant charge essential energetic impulse in time and space, which should provide uniform ignition of all propellant grains. Realisation of this task depends on many factors: mass and type of ignition material in igniter, igniter locations and dimensions, number and diameter of side holes of propellant grains etc. The aim of this work is to investigate closed vessel tests, which permit to see the differences in progress of propellant ignition period. For this purpose the possible infuence of the ignition system and loading density on the combustion rate was investigated. Different ignition systems have been used for the characterization of ignition phase in closed vessel tests. Basic closed vessel experiments were carried out in a conventional closed vessel (CCV) of 200 cm3 . Ignition systems with various mass of black powder were used. Comparable experiments were carried out in a micro-closed vessel (MCV) of 1,786 cm3 and vented closed vessel (VCV) of 200 cm3.
