Description

The invention relates to the field of shipbuilding, namely to launchers (PU) of submarines (PL) and unmanned underwater vehicles (UUV).

The purpose of the invention is to reduce the acoustic signature of the combat use of naval underwater weapons (MPS) from submarines and UUVs.

Covert launchers are known. These include the hydraulic torpedo tube (TA) of the American submarine "Virginia" (Fig. 1), which is installed on this type of submarine, starting with the fourth hull (taken as a prototype). The device contains a torpedo tube (1), front (2) and rear (3) sealing TA covers, a hydraulic firing system, a kingston valve (4). A feature of this launcher is the use of a rubber membrane (6) pre-stretched by a hydraulic pump (5) as a power drive. The absence of air and hydraulic flows in the torpedo (missile, mine) ejection system significantly reduces the acoustic field at the time of the shot.

The disadvantage of such a device is the fact that it does not take into account that the acoustic signature of the shot is associated not only with the force effect on the weapon sample to give it the required separation speed from the carrier. Firing a torpedo is accompanied by the so-called recoil on the submarine's hull. Its deformation generates a low-frequency acoustic pulse in the environment.

The technical result of the proposed device is to compensate for the force impact of the fired weapon on the carrier body with a jet stream of water moving in the opposite direction of the weapon movement.

The technical result of the proposed device is achieved by introducing a compensation ring with a calibrated hole into the torpedo tube.

The proposed invention is aimed at compensating the energy of the shot, excluding deformation of the submarine hull (unmanned underwater vehicle). The launcher (Fig. 2) consists of a pipe (1), front (2) and rear (3) covers, front (5) and rear (6) compensating rings, hydraulic firing system, kingston valve (4). The launcher is located in a strong submarine body, in a vertical position, with its maximum displacement to the center plane. A sample of naval underwater weapons (MPO) can be fired both up and down.

When preparing the torpedo tube for firing, after filling the annular gap with water and equalizing the pressure, both covers are opened. When the sample is fired upwards, the front compensating ring is additionally opened. In this case, the rear expansion ring remains rigidly fixed in the closed state. When water is supplied to the pipe of the torpedo tube, the weapon begins to move upward and part of the water goes down through the compensating ring. The parameters of the compensating ring are chosen such that the reactive reaction of the water jet compensates for the force effect of the weapon being fired on the submarine's hull. Preliminary studies have shown that the optimal hole area in the expansion ring is in the range from 0.15 to 0.25 of the TA cross-sectional area.

When the sample is fired downwards, the front and back covers of the TA and only the rear compensating ring are opened. The rest is done similarly to the case of shooting upwards.

The vertical placement of the TA provides not only the implementation of "recoilless" shooting. This design of the launcher excludes the operation of reloading the TA, which is often accompanied by an increase in the acoustic signature of the carrier, and increases the survivability of the ship by removing the warheads from the hull periphery.

The vertical (more precisely, inclined) placement of launchers was used by German minelayers of the "UC" type during the First World War. Rotary (up to 90 °) launchers are offered in the domestic patent RU 2151711 C1 dated 02.02.1999. Studies have shown that at a product exit speed of 15-17 m / s, the maximum carrier speed at the time of firing should not exceed 9 knots, which is an acceptable level (recall that traverse torpedo tubes, which are equipped with all American submarines, limit the carrier speed when firing 12 -ty knots).
