Description

The invention relates to the field of underwater shipbuilding, and in particular to launchers (launchers), designed for setting / launching weapons and objects for various purposes, and can be effectively used to create specialized sea-based complexes for setting / launching weapons, electronic warfare, trajectory sensors measurements, etc. from a submarine (submarine).

Known launcher submarine (US patent No. 6834608 USA, MKI B63G 8/30; B63G 8/00, F41F 3/00, F41F 3/10.), Which provides its modular loading onto a submarine, launching weapons or other means located outside of a rugged case. The submarine launcher includes a large airtight container (BGK) that can withstand the pressure of the full depth of the submarine, one or more transport and launch containers (TPK) located within a large airtight container and designed to launch and place weapons or other means in them shallow depths, a pressure control system that ensures the opening of the lower lid of the container, after which the transport and launch containers, under the influence of their own weight, exit a large tight wow container.

The well-known launcher has limited functional and operational characteristics, since it is focused on launching objects in transport and launch containers from shallow depths of the submarine and, in addition, the trajectory characteristics of transport and launch containers significantly increase the launch time of the objects placed in them.

Known launcher of a submarine (US patent No. 7032530, MKI B63G 8/28; B63G 8/00), which provides its modular loading onto a submarine, launching weapons or other means, is equipped with one or more air bags. The launcher includes a large cylindrical sealed container with a lid that can withstand the pressure of the full depth of the submarine, one or more waterproof transport and launch containers installed in the frame within the BGK and designed to accommodate and launch weapons or other means (products), air bags installed one and several pumps (gas generators) for pressurization from above and / or along the generatrices of transport-launch containers and designed to ensure the ascent of TPK from BGK nevmopodushek. Advantages of the launcher include ease of loading / unloading weapons, increased density of weapons, reduced weight PU due to the possibility of placement outside the rugged hull of a submarine.

When launching weapons or other means, it is assumed that the submarine will be close enough to the surface of the ocean, so the TPK case is designed for external pressure only at shallow depths.

In the well-known PU (US patent No. 7032530) TPK are flooded with water each time the BGK is filled with water in the process of equalizing the pressure to open its cover when starting up weapons and / or other means, after which one or more pumps (gas generators) inflate the air bags mounted on top and / or along the generatrix of the TPK selected for launch, and the TPK will ascend from the BGK and launch the products.

A disadvantage of the known launcher is its limited functionality, due to the inability to launch objects in the transport and launch containers from the working depths of the submarine, since the body of the transport and launch containers is able to withstand external pressure only at shallow depths.

In addition, the known launcher does not allow the installation of weapons and / or other means according to a given pattern in space.

Known PU submarine according to US patent No. 7032530, including a BGK with a cover, withstanding the pressure of the full depth of immersion of a submarine, one or more waterproof TPKs located within the BGK and designed to accommodate and launch weapons or other means from them, air bags mounted on top and / or along the generators of the transport and launch containers and designed to ensure the floating of the TPK from a large airtight container, one or more pumps (gas generators) for pressurizing air bags is the most bl viscous analog of the claimed PU.

The objective of the invention is to expand the functionality of the launcher for staging / launching products (weapons or weapons for various purposes, for example, electronic warfare, trajectory measurement sensors) by providing the ability to launch objects in the entire range of working depths of the submarine and regularly distributed in space the scheme of their formulation to increase the effectiveness of the totality of the exposed objects.

The problem is solved in that in the well-known launcher, designed for the pressure of the full depth of immersion of the submarine and designed to launch products containing an airtight container for installing launched products with a base (cover) and a hull, as well as an air bag and a gas generator, the hull of the sealed container is made sliding from the base with the possibility of forming an air cushion in the extendable part, guides for products are installed perpendicular to it with the possibility of their dilution under main to the base, while two coaxial pipes are installed in the center of the body of the sealed container, one of which is external, fixed with an end in the center of the base and has a shoulder on its free end that overlaps the section of the sealed container, made with the possibility of sliding along the cylindrical surface of the body of the sealed container and the other pipe, the inner one, is fixed in the center of the extendable part of the body of the said container with the possibility of sliding in the outer pipe, with at least one gasogen The herator is installed in the inner pipe, a restriction seal is made on the edge of the container body, and a container filling valve is in the base.

In addition, the outer pipe has a length not less than the length of the guide along with the installed product, but less than the length of the inner pipe.

In addition, the guides are made in the form of lightweight pipes installed on the base evenly around the circumference and connected to the mechanism of their breeding, and their number corresponds to the number of products launched.

In addition, the retractable part of the container body forming the air bag is made dome-shaped.

In addition, a safety valve and a bleed valve are made in the extendable part of the container body.

The proposed PU device allows to increase its operational characteristics by launching products in the entire range of submarine working depths, as well as by increasing the effectiveness of the set of exposed products due to the scheme of their setting regularly distributed in space. This is achieved through the installation of products in rails fixed uniformly around the base circumference with the possibility of their dilution, as well as by making the case of the sealed container extensible with the possibility of formation of an air bag inflated by means of a gas generator installed in the inner tube of the extension mechanism when sliding in its upper extendable part housing GK.

The air cushion allows you to increase the buoyancy of the PU, since the gas-filled reservoir of the metal body of the sealed container (air cushion) serves as a float after its separation, and the airtight container equipped with launched products installed in the guides serves as a stabilizing anchor. With such a design scheme, a moment is restored that restores to a vertical position, which improves the trajectory of the launcher in the submarine hull area and allows you to quickly start launching weapons or other means.

The invention is illustrated by drawings, which depict:

figure 1 - General view of the launcher installed in the guide products;

figure 2 is a section aa in figure 1;

figure 3 is a General view of the launcher after sliding the housing of the sealed container, breeding guides and launching products.

The submarine launcher (PU PL) contains a sealed container (GK) with a cylindrical body 1 (Fig. 1), which can withstand the pressure of the full depth of immersion of the submarine, with a fill valve 2 made in the base (cover) 3 of the main ship, and also with a safety a valve 4 located in the upper part of the housing 1 of the Civil Code, made dome-shaped. PU can be fixed using the base 3 on the outside of the submarine.

The housing 1 of the main assembly is made sliding, it can be extended from the base 3 using the extension mechanism, which includes two coaxial pipes 5 and 6 mounted on the vertical axis of the housing 1, one of which, external 5, is installed with an end face in the center of the base 3 and has a free the end of the shoulder, made with the possibility of sliding along the inner cylindrical surface of the housing 1 GK, overlapping its section. Another pipe 6, the inner one, is fixed in the center of the retractable dome-shaped part of the housing 1 of the Civil Code with the possibility of sliding in the outer pipe 5.

On the basis of 3 GK installed mechanism 7 breeding guides 8, made by one of the known methods. The guides 8 are made of lightweight pipes and fixed to the base 3 perpendicular to it. The mounting points of the guides 8 are located around the circumference on the base 3 according to a given pattern - at equal distances from each other. The mechanism 7 is intended for the breeding of the guides 8 at an angle relative to the base or relative to the vertical axis of the housing 1 after it is moved apart and after the guides 8 are released with the products 9.

The guides 8 are installed products: weapons or other functional means 9, the body of which must withstand the pressure of the full depth of immersion of submarines with propulsion systems. Regardless of the number of products launched 9, the guides 8 after their dilution are evenly distributed in the horizontal plane.

The outer pipe 5 has a length not less than the length of the guide 8 together with the product 9 installed in it, but less than the length of the inner pipe 6.

To create positive buoyancy PU PU housing 1 can be moved apart under pressure in its internal volume, arising from the operation of one or more gas generators 10 located in the inner tube 6, the inclusion of which is carried out by an electrical signal from the remote control (not shown).

To reduce the load on the housing 1 GC when it is opened, filling valves 2 are provided through which the air voids of the GC are filled with water to equalize the pressure inside the BGK with the outside.

After the casing 1 of the Civil Code is extended, in its upper domed part extended from the base 3, an air cushion 11 is formed, which is a sealed metal reservoir, which is realized in the available volume of the casing of the sealed container after it is opened. Gas generators 10 must provide a sufficient amount of gas for lifting PU from the working depths after they pressurized air bags 11.

To protect the housing 1 GK PU from rupture in the initial period of operation of the gas generator 10, a safety valve 4 is provided. On the edge of the housing 1 GK there is a seal-limiter 12, and a bleed valve 13 for discharging gas is provided in the upper domed part of the housing.

The device operates as follows.

According to the start signal, through the filling valves 2, the air voids of the HA are filled with water to equalize the pressure inside the HA with the outer one to open the housing 1 of the HA. Then, according to a signal from the remote control, a gas generator 10 is activated, generating gas pressure to expand the housing 1 of the main body and to fill the air bag 11 with gas, an airtight metal reservoir, which is realized in the extended upper part of the main body 1 of the main body after it is opened. At the same time, safety valves 4 may trip.

As the air bag 11 is filled with gas, part of the main body housing 1 extends from the base 3. In this case, the inner pipe 6 slides in the outer pipe 5 until the collar of the pipe 5 abuts against the seal - stopper 12. At the same time, the starting products 9 installed in the guides 8 exempted from the Civil Code.

Consistently, after the extension of the housing 1, after the release of the guides 8 with the launch objects - products 9 from the housing 1 of the Civil Code, the signal separates the guides 8 at an angle to the plane of the base 3 or from the central vertical axis of the housing 1 of the Civil Code. The breeding of the guides 8 is due to the operation of the breeding mechanism 7.

In the process of ascent, a sealed metal tank, sold in an accessible volume of the housing 1 GK after its expansion and is a pneumatic pad 11, is used to stabilize the launcher when starting products 9.

After breeding at a certain depth of the guides 8 according to the signal of the starting mechanism (not shown) of the products 9, the propulsion systems of the products 9 are simultaneously launched and they leave the guides 8.

The start-up scheme of products 9 is determined by the resource of their propulsion systems and the installation and breeding scheme of guides 8.

After starting the products 9, the remains of the powder gases flow out through the bleed valve 13 and the used launcher is flooded.

The technical result of the invention lies in the ability to ensure the launch of objects in the entire range of working depths of the submarine and to increase the efficiency of the aggregate of exposed objects due to the scheme of setting them regularly distributed in space.

In 2006, field tests of submarine launcher models with several guides for product placement were conducted.

During the tests, mock-ups of devices were launched from various depths of the launcher and at different angles of dilution of the guides, which confirmed the advantages of the presented launcher.
