Abstract
The invention relates to a water discharge device for a system for launching objects, including torpedoes, mines, or missiles, from at least one tube built into a fixed or movable submerged structure (e.g., a submarine). The tube is provided with at least one end door and one slide valve connecting it hydraulically to the water ram by a impulse tank filled with water. The impulse tank is built into the submarine hull, and comprises a closed, sealed space in which the water is driven to the tube, under the influence of a leading pneumatic ram acting on a following hydraulic ram controlled by the water contained in the chamber and previously drawn in from the marine environment by an intake line. The chamber is immovably located outside the hull. The pneumatic ram and the hydraulic ram of the water ram are removable and independent so that they can be placed in the chamber or be dissociated therefrom, without maintenance work being performed on the hull, and with only the fluid or electrical connections and launch tubes, properly passing through the hull. The device also has a compressed-gas reservoir directly connected to the piston of the leading pneumatic ram to drive and displace…
