SUBMARINE LAUNCHER Russian patent published in 2019 - IPC B63G8/28 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of underwater shipbuilding, namely to intra-compartment launchers intended for setting-launch of electronic warfare and hydroacoustic countermeasures and other devices for various purposes, and can be used in development of specialized sea-based systems for placing and launching of articles from submarines. Submarine launcher includes an external housing in which there is coaxially installed a cylindrical linear electric motor with a movable rotor, upper outboard and lower inner-compartment covers and their drives, terminals for connection of filling, dehumidification and pressure balancing lines. Linear electric motor is made with two cylindrical concentric stators isolated from water medium by polymer material, and with one tubular rotor, which is made with double-sided active surface and is installed coaxially in annular gap between stators with possibility of its movement along axis of external housing and compensation of radial forces generated by stators acting on rotor. At that, the launcher unit is equipped with an annular hydraulic piston coaxial to the rotor, which is installed by its external side surface along the movable fit on the external housing above the stators, the working surface is connected to the rotor, and on inner surface of piston is coaxially fixed guide tube installed in internal volume of internal stator with formation of annular gap with possibility of formation by housing, piston with guide pipe and ejected product of closed hydraulic cavity for creation of excess water pressure at movement of piston and guide pipe towards ejected article passing inside guide pipe.

EFFECT: technical result is higher specific power, reliability and universality of launcher.
