FIELD: weapons and ammunition.
SUBSTANCE: ammunition leading part separation unit contains the shell with the bottom, the support ring with the forced crossing unit, piston, forced crossing charge, the cartridge pressure accumulators, the working and accumulating cavity for the charges combustion products. The cartridge pressure accumulators are fixed in the piston of the separation compartment. It is placed with nozzle clusters opposite the gas-dynamic windows. Such position allows the combustion products to fill the accumulating cavity. The above mentioned windows are made in the intermediate diaphragm rigidly fixed to the supporting ring of the shell. The nozzle clusters of cartridge pressure accumulators are provided with devices of nozzles simultaneous opening. It is made in the form of the plugs placed in the outlet part of the nozzle and having the induced drafts. These drafts are fixed in the intermediate diaphragm and connected with nozzle plugs and by means of the stop and threaded type detachable joints.
EFFECT: improvement of device operation reliability.
