DEVICE CHARGES igniting solid rocket motor firings

摘要

The invention relates to devices for the igniter rocket engine with a charge of solid fuel. Igniting device rocket motor solid propellant charges comprises a movable element made of a hollow cylindrical cup with radial nozzles and located inside lifting igniter composition. Thus on the front face of the cup formed end nozzle and radial nozzles are arranged on the side surface of the glass at an angle relative to the centerline of nozzle lines. The advantage of the proposed design is to increase the efficiency of the movable part igniter device by providing the desired speed of movement of the movable member, providing a uniform ignition of the solid propellant charge surface.
