Description

The invention relates to military equipment, specifically, to devices for installing communications equipment on a multiple rocket launcher (BM MLRS) combat vehicle, made on a basic tank chassis, and is designed to organize a communication system according to the scheme for dividing working areas into a chassis and a turntable launcher.

A tank communication device and a device for its installation are known (RU, utility model according to patent No. 36139, F41Η 7/02, F04B 7/00, 2009).

The tank communication means contains a radio station, an antenna device, a tank intercom with the apparatus of a driver, gunner and tank commander, switching equipment and cable connections. As a radio station, a regular single-channel transceiver radio station of the R-173 family was used. It can also be used, made at a more modern level of receiving and transmitting two-channel radio station R-168-25UE-2. The radio station is installed in the area of the commander's workplace in a removable container. The container is equipped with connecting electrical connectors for connecting the said radio station, as well as for a long-distance radio station.

Device for installation of means of communication comprises fixed places for standard means of communication made in the hull and turret of the tank, a set of removable adapter brackets made with the possibility of fixing elements of means of communication (intercom of a driver, communication device of a tank intercom of a commander, container of a radio station) and a set of fasteners elements (screws, bolts, studs, etc.)

Technical solutions according to patent No. 36139 can be used to install communications equipment on domestic tanks, mainly on tanks of the T-80 family, and cannot be applied to BM MLRS. In addition, the design of the device for installing a communication means is not designed for installing digital foreign means of communication (instead of analog domestic production).

As a prototype, a set of equipment was chosen for installing communications equipment on a combat vehicle of a multiple launch rocket system made on a tank chassis (“Product 634B. Combat vehicle of the TOS-1A system. Technical description. Part two”, Omsk, OAO KBTM, 2009, pp. 1, 153-156).

The specified combat vehicle is a launcher mounted on a turntable on a tank chassis. The workplaces of the commander and operator-gunner are located in the fighting compartment in a turntable. In the base chassis, the design and relative position of the components and mechanisms of the power plant, tank transmission are preserved, and the driver's workplace is located.

The placement of communications equipment in the combat vehicle is similar to the layout of the tank communications equipment.

The composition of the communication means of the specified combat vehicle for external communication includes a two-channel VHF transceiver radio station of the R-168 family (R-168-25UE-2), and the internal communication and switching equipment (AVSKU) was used as an internal communication in the following configuration: subscriber device commander, subscriber device of the gunner and subscriber device of the driver. Due to the fact that the workplaces of the commander and the gunner and, accordingly, their subscriber devices are located in the turntable and move with it, the transmission of intercom radio signals between the driver and the rest of the crew is carried out by means of a rotating contact device (VKU), which provides through a low-current contact system, radio communication between the driver and the crew, regardless of the position of the turntable relative to the chassis.

The set of equipment for the installation of communications equipment contains a set of adapter brackets for fixing blocks of internal communications, including subscriber devices of the driver, commander and gunner, and external communications on standard shock-absorbing panels, connecting cables with quick connectors, including a cable for connecting to the VKU, a cable for electrical connection of subscriber intercom units with a system of collective protection against radiation contamination, a fire extinguishing system and an alarm system of the chassis and a cable for connecting communication equipment to the on-board power supply network, an antenna and a set of mounting elements.

The shortcomings of this kit include:

- does not meet the requirements of unification, tk. when supplying combat vehicles, including for export, the composition of communication equipment, the architecture of building radio transmission networks, the procedure for using communication systems and other technical requirements are determined by the customer, and when using the specified kit, these requirements cannot always be met, especially when installing communication equipment of a foreign production, requiring the organization of new installation sites for their installation and placement in limited volumes of the fighting compartment;

- when installing digital foreign means of communication (instead of analogue domestic production) on a vehicle already assembled and completely handed over to the customer, it is not possible to provide the driver with an internal communication channel and an alarm channel through the VKU, the design of which is not designed to transmit digital information. In this connection, design improvements are needed to provide digital communication channels;

- when exporting a combat vehicle, it is not always possible to carry out an objective prototyping of subscriber communication devices offered by a foreign customer on the territory of Russia, and fitting "in place" of their installation locations (in particular, welding) and adapter brackets;

- in addition, in case of export delivery, the combat vehicle is assembled and acceptance tests are carried out in Russia, and the installation of foreign-made communication units and cables is carried out on the territory of a foreign customer. Such a scheme of equipment leads to the need for additional measures for the dismantling of the combat vehicle, namely, the dismantling of the turntable of the launcher to provide access to the VKU, and then reassembly and retesting.

The technical result of the invention is to provide the possibility of expanding the range of communication means installed on the BM MLRS without performing work on finalizing and dismantling its design.

The technical result is achieved by the fact that in a universal set of equipment for installing communications equipment on a BM MLRS, containing a set of adapter brackets for fixing the internal communications equipment of the driver, commander, gunner and external radio communication equipment in regular places, connecting cables with quick disconnect elements, including a cable for connecting to a rotating contact device (VKU), which provides electrical communication and radio communication between the chassis and a rotating turntable, a cable for electrical connection of the intercom equipment with a collective protection system against radiation contamination, a fire extinguishing system and an alarm system for the chassis of a combat vehicle, a cable for connecting subscriber devices of intercom means to the on-board power supply network and the cable of the driver's headset, an antenna and a set of mounting elements, according to the invention, to enable switching signals and their redistribution through the VC circuits At the turntable, the kit contains an interface unit with an integrated connection system, made in the average overall dimensions of the subscriber device of the driver’s communication means, installed in its regular place and providing it with internal communication channels, emergency and warning signals, cables for connecting the interface unit to the VKU and to alarm systems, a kit for refining the cable of the driver's headset, while the set of adapter brackets and the set of mounting elements are made taking into account the specified type of installed communication means.

At the same time, a universal set of equipment for installing communications equipment on a BM MLRS contains a protective cover for the radio connectors.

At the same time, the interface unit is made in a dust and moisture-proof housing, on which sealed connectors are placed.

At the same time, the kit for finalizing the cable of the driver's headset contains two connectors for connecting one part to the VKU, and the second part to the interface unit, and elements to ensure the possibility of manufacturing two cable assemblies in accordance with regulatory documents for cable products;

Analysis of the distinguishing features showed:

- the presence in the universal set of equipment for installing communication means of an interface unit with an integrated connection system, which provides the ability to switch signals and redistribute them through the VKU circuits to the BM MLRS turntable, allows without additional installation and dismantling work (organization of new installation sites that require welding is not required , drilling, etc. and performing work on dismantling structures) to connect various types of communication means, both digital foreign production and technological communication means of domestic production, tk. modern communication equipment, including foreign-made equipment, is made in accordance with the standards for military equipment, and in conditions of a high level of standardization and interchangeability, the manufactured modern communication equipment for armored vehicles has similar overall dimensions, sizes of mounting holes, as well as a similar quantitative composition . These technological means of communication are temporarily installed during the manufacture and testing of the quality of BM MLRS. In addition, the presence of an interface unit makes it possible, when installing digital communications, to provide the driver with an internal communication channel and a channel for emergency and warning signals. This is possible because the number of circuits transmitted to the driver's headset in foreign means of communication is similar to domestic ones and analog signals are transmitted through electrical circuits, which makes it possible to transmit these signals through the VKU. Thus, the presence of an interface unit with an integrated connection system makes it possible to expand the range of installed communication means without performing work on finalizing and dismantling the BM MLRS structures.

- the implementation of the interface unit in the average overall dimensions of the subscriber's unit of the driver of the intercom and placement in its regular place allows, in the conditions of a dense layout of the control department, to leave the layout solutions unchanged and ensure ergonomic requirements for the workplace of the driver;

- the presence in the claimed set of cables for connecting the interface unit to the VCU and to the alarm systems ensures the implementation of the functional purpose of the interface unit;

- the presence of a kit for finalizing the cable of the driver's headset is necessary for dividing the specified cable into two parts in order to connect one part to the VKU, and the second part to the interface unit. The need to refine the cable of the driver's headset is due to the inaccessibility of connectors used according to the foreign-made military communication standard and implements the possibility of transmitting an analog signal applied to the headset through the VKU;

- the implementation of a set of adapter brackets and mounting elements, taking into account the specified type of installed communication means, allows the use of the claimed set of equipment for installing almost all types of communication means, by the possibility of correcting their design differences by changing the shape and size;

- the presence of a protective cover for the radio connectors provides protection for the radio connectors facing the gunner in the cramped conditions of the VGM layout, in addition, the gunner is protected from static electricity accumulated on his clothes;

- implementation of the interface unit in a dust- and moisture-proof housing with the use of hermetic and sealing gaskets in the design ensures the operability and reliability of the unit in various climatic conditions of use.
