Abstract
A system for reducing the temperature-dependent influence of the powder on the muzzle velocity of ammunition units on discharging of the ammunition units from a barrel of a large-caliber gun with high muzzle velocities includes a plurality of part charges having predetermined types, powder varieties, charge sizes and geometric dimensions of the powder, controlling unit for determining desired muzzle velocities based on predetermined parameters including influence of a powder temperature in the part charges during discharging from the barrel so that the desired muzzle velocity of respective ammunition units and barrel pressures do not exceed a predetermined acceptable value while ensuring the highest possible performance of the gun and for determining a corresponding predetermined combination of part charges to achieve the desired muzzle velocity, and selecting and assembling devices responsive to the signal from the controlling unit for selecting predetermined combinations of part charges from a plurality of part charges, so that the respective part charges in each combination contribute to achieving the desired muzzle velocity determined by the controlling unit.
