MULTIBARREL LAUNCHER Russian patent published in 2003 - IPC

FIELD: military equipment. SUBSTANCE: in compliance with invention multibarrel launcher has base, block with N guides, power supply unit, electric motor drive to aim block with guides, unit controlling electric motor drive which includes first, second and third switches, limit switch mechanically coupled to block of guides, first logic OR gate, first and second flip-flops, and shell launching circuit incorporating fourth switch, pulse generator, shift register and ignition circuit of electric fuses of shells. Output of power supply unit is connected through make contacts of first and second switches to information inputs of first and second flip- flops correspondingly and through make contacts of fourth switch to input of pulse generator which output is connected to input of shift register. Each of N outputs of shift register is connected to ignition circuit of electric fuse of proper shell and output of power supply unit is connected through make contacts of third switch to first input of first logic OR gate which second input is connected through break contacts of first and limit switches to output of power supply unit. Output of logic OR gate is connected to setting inputs of first and second flip-flops which outputs are connected correspondingly to first and second inputs of electric motor drive of block with guides. Launcher is supplemented with second logic OR gate, logic AND gate, unit determining number of shots, shot counter, comparator and indicator. Third input of first logic OR gate is connected to output of logic AND gate, outputs of first and second flip-flops are connected correspondingly to first and second inputs of second logic OR gate which output is connected to first input of logic AND gate whose second input is coupled through make contacts of fourth switch to output of power supply unit. Output of logic AND gate is connected to input of pulse generator which output is coupled to input of shot counter whose output is linked to first input of comparator. Second input of comparator is connected to output of unit determining number of shots and its output is coupled to input of indicator and third input of logic AND gate. EFFECT: enhanced functional reliability and safety of multibarrel launcher due to prevention of possibility of combined of operation of electric motor drive with launch of shells. 1 dwg
