Description

The utility model relates to the field of military equipment, namely, to mobile carriers of ammunition for multi-barreled weapons, and can be used to load the launcher of a multiple launch rocket system combat vehicle (BM MLRS).

Known transport and loading machine (TZM) on a tank chassis (RU, utility model according to patent No. 27202, F41A 9/35, F41A 9/87, 2002) for the launcher BM MLRS, made while maintaining the design and the relative arrangement of nodes and mechanisms the power plant, transmission and chassis of the base tank chassis, containing lodgments placed on the hull and the roof for placing the stowage of projectiles, equipped with a protective casing, a manipulator with hydraulic drives, equipment for loading the launcher with rockets, equipped with a device for guiding projectiles and orienting them when loading.

The disadvantage of the known TZM is the lack of a system for ensuring comfortable microclimate conditions at the workplaces of crew members.

The experience of using Russian military equipment in hot climatic conditions made it necessary to refine it in terms of ensuring comfortable living conditions for the crew members. Currently, more and more objects of military equipment are equipped with air conditioning units.

Thus, an armored vehicle (RU, invention under patent No. 2465537, F41H 7/00, B60N / 32, 2011) is known, containing a hull, a turret, an inhabited compartment with workplaces for crew members, a power supply system, and a life support system. The life support system contains a filtering unit and an air conditioning unit containing a cooling circuit and a heat removal circuit to the atmosphere. The cooling circuit contains a ventilation-cooling unit, each of which has a cooling unit, a device for creating an air flow to a crew member. The heat removal circuit to the atmosphere contains an expansion tank and a container with holes, inside which there is a heat exchanger, a device for creating an air flow to the atmosphere, a pump and a control unit. All ventilation-cooling units are controlled by a single control panel.

However, the installation for air conditioning of a well-known armored vehicle cannot be used on the TZM without changing its layout due to its functional purpose and the difference in the location of the commander and gunner's workplaces in it. In addition, the specified air conditioning unit has low vibration resistance and uses refrigerants that are toxic to humans, such as freon, to cool the air.

As a prototype, the TZM heavy flamethrower TOS-1 A was chosen, made on the chassis of the T-90S tank (Transport-loading vehicle TZM-T of the TOS-1 A heavy flamethrower system. Technical description. Part 1. 563 TO-05, Omsk, JSC KBTM, 2009, p. 12, 14, 55, 130-131, Fig. 3, 7, 136), containing lodgments placed on the body and the roof for placing shells, each of which is equipped with a protective casing, a manipulator with hydraulic drives, loading equipment missile launcher, life support system, control compartment located in the chassis housing with workplaces for the commander, operator and driver. The life support system includes a filtration unit and individual blowing fans to reduce the thermal effect on the crew members. Individual blowing fans ensure the formation of air flow and its delivery to the area of the crew's workplaces, thereby ensuring air circulation in the crew compartment.

The disadvantage is that during the operation of this TPM in a hot climate, its life support system, due to the low cooling efficiency of the inhabited compartment, does not allow creating comfortable microclimate conditions at the workplaces of the crew members.

The technical result of the utility model is to provide comfortable microclimate conditions at the workplaces of the TPM crew members.

The technical result is achieved by the fact that in a transport-loading vehicle on the chassis of a base tank for a combat vehicle of a multiple launch rocket system, containing cradles placed on the body for placing projectiles, each of which is equipped with a protective casing, a manipulator with hydraulic drives, equipment for loading the launcher with rocket projectiles, a life support system, a manned compartment located in the chassis hull with workplaces for the commander, operator and driver; according to the utility model, the life support system contains an air conditioning system, including a heat dissipation radiator unit installed outside on the roof of the hull in an area that ensures unhindered loading and unloading of projectiles, individual thermoelectric cooling units for crew members' workplaces, each of which is located in the immediate area of the crew member's workplace, connected to the radiator unit by pipelines, hermetically passing through the roof of the hull, when however, each individual cooling unit is equipped with controls.

In this case, the heat-release radiator unit is installed on the roof of the case behind the left protective casing and includes a container in which the control unit is located, a heat-release radiator with fans, an electric liquid pump and an expansion tank.

In this case, the commander's cooling unit is installed on the roof sheet of the control compartment in front of his workplace.

At the same time, the operator's cooling unit is installed on the roof sheet of the control compartment in front of his workplace.

In this case, the driver's cooling unit is mounted on brackets at the driver's workplace.

The analysis of the distinctive features showed that:

- the presence of an air conditioning system ensures comfortable microclimate conditions at the workplaces of the crew members during the operation of TPM in countries with a hot climate;

- implementation of the air conditioning system in the form of separate units: a radiator unit for heat release and individual cooling units for the work places of the crew members, ensures its compactness and the possibility of placing it on the TPM without performing work on the completion and dismantling of its structure, while ensuring the compactness and reliability of the structure. In addition, the block execution of the air conditioning system helps to reduce the time for its installation and increases maintainability;

- installation of a heat dissipation radiator block outside on a rotary housing on the roof of the hull in an area that ensures unhindered loading and unloading of shells, as well as removal and installation of protective shells for shells, turning the crane installation, makes it possible to install an air conditioning system on the TPM without deteriorating its tactical and technical characteristics ... The most rational is to place the heat sink unit on the roof of the case behind the left protective casing;

- connection of individual cooling units for crew members' workplaces with a heat-release radiator unit with pipelines, hermetically passing through the roof of the turntable, ensures the safety and tightness of the habitable compartments;

- equipping each individual cooling unit for crew members with controls allows each member of the TPM crew to individually adjust the air conditioning process at his workplace;

- the placement of the heat release radiator unit in the container ensures its compactness, simplifies its installation on the machine without modification and changes in the design of the latter, and excludes the effect of the gas jet of the launcher on it when launching rockets;

- implementation of the thermoelectric air conditioning system, by making individual thermoelectric units for cooling the crew members' workplaces with thermoelectric ones, simplifies its design, ensures reliability in conditions of increased vibration loads arising during machine operation, and also simplifies maintenance.

The tightness of the habitable compartment in the place where the pipelines pass is ensured by making a bushing 30 with a sealing ring 31.

The air conditioning system operates as follows.

When the air conditioning mode is turned on, at least one of the individual cooling units 10, 11, 12 is supplied with an electrical signal to the control unit 24, which gives a signal to turn on the fan 26 (Fig. 6) of the radiator of the fan 21 of the individual cooling unit and the pump 27 for pumping the working liquids. At the same time, LED 18 lights up on the cooling unit to indicate the activation of the "Air Conditioning" mode.

The air in the habitable compartment of the TZM is directed by a fan 21 through a heat exchanger with thermoelectric cooling modules, during the passage of which it is cooled, to the work area of a crew member, which by deflectors 14 regulates the direction of the air flow. The heat generated during the operation of the thermoelectric cooling module is removed by the working liquid, pumped by the pump 27 through the pipelines 29 to the heat dump radiator 25, where it is utilized into the surrounding air. Air is supplied to the heat dump radiator 25 through hole "a", from the surface of which the fans 26 through the outlet "b" are discharged into the atmosphere, and the cooled working fluid is again fed to the heat exchanger of the cooling unit 10, 11, or 12.

When the level of the working fluid in the expansion tank 28 drops below the critical level, the working fluid level sensor is triggered, from which a signal is sent to the control unit 24. From the block 24, the signal is sent to all cooling units 10, 11, 12, on which LED 19 lights up indicating the minimum working level. liquids.

When the air ventilation mode is turned on by switch 16 on at least one of the cooling units 10, 11, 12, a signal is sent to the control unit 24, which gives a signal to turn on the fan 21, while the radiator fans 26, the heat exchanger with thermoelectric cooling modules and the pump 27 for pumping of the working fluid remain in the off position. The air of the manned compartment of the TZM is directed by a fan 21 through a heat exchanger with thermoelectric cooling modules to the area of the crew member's workplace, which by deflectors 14 regulates the direction of the air flow.

Thus, the solutions proposed in the utility model have achieved a technical result to ensure comfortable microclimate conditions at the workplaces of the TPM crew members.
