SUBMARINE LAUNCHER Russian patent published in 2009 - IPC B63G8/30 F41F3/07 

FIELD: shipping industry.

SUBSTANCE: invention refers to underwater shipbuilding, and namely to launchers intended for setting/starting-up the items and objects of different purpose, sensors, etc. Launcher consists of a pressure-tight container for the items being launched, with a casing and bottom, as well as with an air bag interconnected with a gas generator. Casing is made extendable so that therein there can be formed an air bag; at the bottom perpendicularly thereto there installed are guides for the items so that they can be taken away at an angle to the bottom. At that in the container casing centre installed are two annular tubes the outer one of which is attached with its end to the bottom centre and has a collar on a free end, which is made with the possibility of sliding on the inner cylindrical surface of the container casing. Inner tube is fixed in the centre of the top retractable part of the container casing with the possibility of sliding in outer tube. At that gas generator is installed in inner tube; on the container casing edge there provided is a sealing-stop, and at the bottom - container-filling valve. Length of outer tube cannot be less than length of the guide together with installed item, but can be less than inner tube length. Guides can be made as light-weight tubes uniformly installed at the bottom in a circumferential direction and connected to the mechanisms which take them away, and number thereof can correspond to the number of items being launched. It is expedient to make retractable part of the container casing, which forms an air bag, as dome-shaped. In retractable part of the container casing there can be provided safety and pressure-relief valves.

EFFECT: invention allows improving functional capabilities of the launcher.
