METHOD OF FIRING ANTIAIRCRAFT GUIDED ROCKET AND ROCKET FOR ITS REALIZATION Russian patent published in 2002 - IPC

FIELD: antiaircraft armament. SUBSTANCE: method of firing antiaircraft guided rocket includes acceleration of antiaircraft rocket in two stages: first by primary low-thrust engine with powder charge of low-smoke fuel and then by sustainer engine to design terminal velocity. On termination of operation primary engine is separated from antiaircraft guided rocket with separation speed less or equal to velocity of antiaircraft rocket. Sustainer engine is switched on with delay, after separation of primary engine. Proposed method is realized with the use of antiaircraft rocket placed in transportation and launching matrix and comprising main stage of rocket and separable boost engine docked to it by means of stage separation mechanism. Rocket is fitted with primary low-thrust engine with powder charge of low-smoke fuel. Primary engine is installed in outlet part of nozzle of sustainer engine and is attached to it with the use of breakable elements. Separation chamber with thin- arch powder charge and ray igniter of delayed action is positioned by front bottom of primary low-thrust engine. Sealed electric connectors forming circuit of ignition of primary engine jointly with connecting wires are mounted in front cover and nozzle membrane of sustainer engine. EFFECT: invention ensures antiaircraft rocket firing over large range from combat vehicle in motion and enhances reliability of combat vehicle as whole. 6 cl, 4 dwg
