SUBMARINE LAUNCHER Russian patent published in 2018 - IPC F41F3/07 

FIELD: shipbuilding; weapons and ammunition.

SUBSTANCE: invention relates to launchers of submarines. Submarine launcher comprises a launch tube with the upper outboard and the lower intra-compartment covers and their drives, terminals for connecting the lines of ventilation, filling, dehumidifying and pressure equalizing. Coaxial with the launch tube an outer shell is installed forming in the upper outboard part a closed annular volume between them, in which a linear electric motor is installed. Stator of the electric motor is made in the form of an integrate structure with the outer shell and is isolated from the water environment. Rotor is made in the form of an annular piston-kingston with a non-return valve able to perform a linear controlled movement in the annular volume and is mounted on a fit in the inner diameter of the stator and with a seal on the outer surface of the launch tube. In the lower intra-compartment part the outer shell is installed to the launch tube forming an annular gap and is hermetically sealed by the lower cover with the possibility of water inflow from the annular gap into the lower part of the launch tube.

EFFECT: decreasing the launch noise and increasing the rate of fire and the universality.
