MULTIPLE-BARREL LAUNCHER ON LIQUID PROPELLANTS Russian patent published in 1994 - IPC

FIELD: artillery equipment. SUBSTANCE: launcher on liquid propellants comprises barrel 1 with missile fixing device 2, combustion chamber 3 and ignition device in the form of receiver with solenoid valve 5. Metering system consists of receiver with spring-loaded rod-piston 9 for each component whose filling travel is limited by screw stop. Receiver chamber is closed by nonreturn valve from filling pipe, and by valve 7 in injector, from combustion chamber. Rod-piston is driven by stepped chamber filled with liquid communicating with rod end of rod-piston and differential piston 13. Gas pressure built up in ignition device and by burnt components of fuel acts on differential piston and, via the service fluid, moves rod-pistons until fuel components are completely forced into combustion chamber. EFFECT: gradual change of initial missile speed and higher operating safety. 3 dwg
