Description

The proposed utility model relates to military equipment and can be used in the design of self-propelled artillery guns.

Known 152-mm upgraded self-propelled howitzer 2S3M "Acacia" (Encyclopedia of armored vehicles, tracked combat vehicles 1919-2000, Kholyavsky GL, "Harvest", 2001, pp. 192-196) containing a tracked chassis with thin-armored housing, in front and on the right is a sealed motor-transmission compartment. On the upper part of the hull behind this compartment, a circular-rotation tower is mounted on a rotary support device with an artillery gun of 152 mm caliber separate-shell loading. The shells are located in the carousel in the aft of the tower and in the honeycomb in the aft of the chassis, and the charges are located in the panel of the fighting compartment. Ammunition is 46 rounds. After the shot is fired, the sleeve is manually removed outside the tower. Ammunition loading is done manually through the hatch in the aft overhead sheet of the hull.

On 2С3М there are two filter-ventilation units (FVU) similar in design: one in a special compartment on the left wing liner of the hull, the other in an airtight compartment in the right front of the tower. Each filtering installation consists of a supercharger, valve box, filter-absorber, control mechanism and connecting pipes. Filter-ventilation units are designed to supply purified air to the inhabited compartment and create excessive pressure (back-up) in them, as well as for ventilation and to reduce their gas contamination during fire work.

The supercharger valve control mechanism consists of a handle with a cam, a stopper, and a housing for the squib. When the handle is rotated, the cable in the gutter of the cam is pulled, compresses the spring and opens the valve. The stopper, under the action of the spring, enters the groove of the cam and holds it in this position. At the same time as the valve opens, the stem acts on the limit switch, which turns on the supercharger motor. To close the valves manually, pull off the stopper ring. When the valves are automatically closed, the stopper moves under the influence of a pyro cartridge explosion. At the same time as the valve closes, the supercharger motor is turned off.

The pointing angles in the vertical plane are from - 4 ° to + 60 °. Rate of Fire 3.5 shots / min. The combat weight of the self-propelled howitzer is 27.5 tons. Crew 4 people. The engine and transmission compartment has an internal combustion engine with a capacity of 382 kW. The transmission is mechanical. The maximum speed on the highway is 60 km / h. Cruising on the highway 500 km.

The disadvantage of this design is:

- small ammunition load of shots;

- small elevation angle;

- the transfer of ammunition to the loading line is carried out manually, as a result, low rate of fire;

- due to the low power of the internal combustion engine, the speed on the highway and rough terrain is low;

- there is no autonomous unit for generating electricity for consumers when firing at a firing position, as a result, the resource consumption of the sustainer engine;

- a manual actuator for controlling the valve of the blower of the filter-ventilation installation does not allow automating the inclusion of the filter-ventilation installation during firing;

- a one-time action during automatic closing of the valve of the blower of the filtering and ventilation unit from the squib;

- self-propelled artillery howitzer was developed for the domestic customer of weapons, as a result, there is no development of 155 mm howitzer guns for the domestic tracked chassis.

Known self-propelled artillery PzH 2000 (German Panzerhaubitze 2000 - armored howitzer) (information taken from the Internet, the free Wikipedia encyclopedia), developed by Krauss-Maffei Wegmann in 1998. The self-propelled guns are equipped with a 155-mm 52-gauge cannon, a navigation system, an automated fire control system, an automatic loading system with 60 rounds of ammunition and 228 modular projectile charges. The combat weight of 55.3 tons. The crew of 5 people. Angles of vertical guidance from - 2.5 ° to + 65 °. Maximum engine power 1000 hp Speed on the highway 67 km / h, cross-country - 45 km / h. Cruising on the highway 420 km. The PzH 2000 is capable of firing 3 shells in 9 seconds or ten shells in 56 seconds at a range of 30 km.

The disadvantage of this design is:

- large combat mass;

- small angles of elevation of the gun;

- low maximum rate of fire;

- The range on the highway is small.

The closest to the proposed utility model in terms of essential features is the upgraded 152 mm self-propelled artillery gun 2S19M1 Msta-S (see technical description 2S19M1 on the Rosoboronexport website [http://roe.ru/catalog/sukhoputnye-vosyka/ msta-s-asuno /]), comprising a tracked chassis with a thin-armored hull, which includes a traffic control compartment, a main weapon fighting compartment, a pressurized motor-transmission compartment located in the rear of the hull. In the middle part of the chassis, a tower of circular rotation is mounted on a slewing ring with an artillery gun of caliber 152 mm of a separate-shell loading. Carried ammunition is 50 rounds. Crew 5 people. The combat weight is 42 tons. Guidance angles in the vertical plane are from - 4 ° to + 68 °. The propellant charge is equipped with a fireproof metal sleeve. The breech of the gun with a loading line is enclosed in a sealed casing, in the lower part of which there is a mechanized tract for removing spent cartridges through the hatch in the mask of the gun. On the right side of the casing, a coordinator is installed on the axle of the gun for transferring the projectile from laying on the loading line. The shells are placed in two mechanized stacks. Throwing charges are installed in non-mechanized stacking. The propellant loaded in the sleeve is transferred to the charging line manually. Rate of fire is 8 rds / min. An 840 hp internal combustion engine is installed in a sealed engine and transmission compartment. The maximum speed on the highway is 60 km. Cruising on the highway 500 km. In the aft part of the left side of the tower mounted conveyor with a power drive for loading propellant charge. In addition, on the aft leaf of the tower there is a mechanism for feeding the projectile from the ground for mechanized loading of shell stacking cells. In order to move the projectile sent to the cell of the mechanized conveyor laying, to the coordination unit, the cell with the projectile must be moved 2 steps to the right before alignment with the sending line to the coordination unit (Fig. 3). To repeat the cycle of loading from the ground, the cell must be returned from the sending line to the coordination unit to the sending line from the mechanism for feeding shells from the ground. In the sealed compartment at the rear of the tower, an autonomous unit for generating electricity of a gas turbine type with a capacity of 16 kW and a fuel tank for operating the unit are installed.

In the 2S19M1 self-propelled howitzer there are two filter-ventilation installations of similar design, they are located in airtight compartments in the front of the tower: one on the left and the other on the right. Each filter ventilation installation consists of a supercharger, valves, a filter-absorber, a control mechanism, connecting pipes and air ducts. Air intake is carried out through the ducts from the zone of least gas contamination in the rear of the tower. When the handle is rotated, the cable through the cam compresses the springs and opens the valves. At the same time as the valve opens, the stem acts on the sensor, which turns on the supercharger, and the stop of the control mechanism stops the cam. To turn off the HLF, pull the ring of the supercharger control mechanism. In addition, shutdown can occur automatically from the squib mounted in the housing of the control mechanism. In both cases, the supercharger will stop and the valves will close.

In the engine-transmission compartment, units and components from the T-72 tank.

The disadvantage of this design is:

- a small angle of elevation of the gun due to the presence of a casing, in the lower part of which there is a tract for removing fireproof metal shells, as a result, reducing the minimum firing range;

- low specific power of the internal combustion engine;

- significant loading height of the mechanism for supplying charges from the ground due to the lower location of the drive and the circuit and, as a result, the inconvenience of loading the charge;

- limited access to the mechanism for laying the charge;

- the line of sending to the coordination unit has a lateral shift of two steps of mechanized laying to the starboard side relative to the line of sending from the mechanism for feeding shells from the ground and, as a result, a decrease in rate of fire;

- the gas turbine power unit does not provide comfortable microclimate conditions in the inhabited compartment for operation in the Far North and southern regions;

- a manual actuator for controlling the valve of the blower of the filter-ventilation installation does not allow automating the inclusion of the filter-ventilation installation during firing;

- a one-time action during automatic closing of the valve of the blower of the filtering and ventilation unit from the squib;

- the manual drive of the supercharger valve control determines the placement of the HLF in the immediate vicinity of the crew’s workplaces, which, as a rule, is not optimal for air intake.

The objective of the proposed utility model is the creation of self-propelled artillery gun shellless loading caliber 155 mm of domestic production:

- with increased rate of fire when operating in firing mode with the supply of ammunition from the ground;

- with an increased elevation angle of the gun;

- with improved conditions for loading charges from the ground;

- with the possibility of placing in stacks an expanded range of shells;

- with comfortable microclimate conditions in the inhabited compartment;

- with the optimal location of the HVF with air intake from the zone of least gas contamination;

- with FVU with a remote valve actuator and the possibility of multiple actions when turning on and off in automatic mode.

The solution to this problem is achieved by the fact that a self-propelled artillery gun containing a tracked chassis with a thin-armored hull, in the rear of which there is a motor-transmission compartment with an internal combustion engine, on the upper part of the hull there is a turret on a rotary support device, in which the mechanized weapons are placed laying with cells for shells, laying for projectile charges, coordinator for transferring shells from laying on the gun’s loading line, autonomous gas turbine a power unit for the work of energy consumers, in the rear of the tower there is a mechanism for delivering propellant charges from the ground, while the artillery shellless loading gun has a caliber of 155 mm and its barrel length is 52 kb, the sending line from the mechanism for feeding shells from the ground is combined with a mechanized laying cell and with the line of sending the projectile to the coordinator. The mechanized stacking cells are equipped with movable elements restricting the longitudinal movement of the projectile in the cell. In addition, the mechanism for supplying charges from the ground is located outside the tower and is made with the top location of the drive and the circuit, moving the charge into the fighting compartment. An autonomous gas-turbine power unit is made with an air conditioning and heating device in the inhabited compartment. The filter-ventilation installation, located in the aft part of the tower, contains a remote actuator for controlling the FVU valve with an electromechanism and an electromagnet.

A 1000-hp internal combustion engine is installed in the engine-transmission compartment.

Self-propelled artillery gun (Fig. 1) contains a tracked chassis 1 with a thin-armored hull, in the rear of which there is a motor-transmission compartment 2 with an internal combustion engine 3 with a capacity of 1000 hp The components and assemblies of the engine and transmission compartment are unified with the components and assemblies of the T-90 main battle tank. A tower 4 is mounted on the upper part of the housing on a slewing ring. The turret 4 houses a shellless artillery gun of 5 caliber 155 mm with a barrel length of 52 klb, mechanized stacking 6 with cells for shells 7, styling for propelling charges (not shown), coordinator 8 for transferring shells from stacking to gun loading line 5, autonomous gas turbine power unit 9 for energy consumers. In the aft of the tower 4 there is a mechanism for supplying propellant charges from the soil 10. The nodes of the charging system are arranged in series (Fig. 4), i.e. the line of sending 11 from the mechanism for supplying shells from the ground 12 is aligned with the cell 7 of the mechanized stacking by the line of sending the shell 13 of the projectile to the coordinator 8. During loading from the ground, the projectile has only longitudinal movement along the path. Cell 7 mechanized laying 6 is equipped with movable elements 14, limiting the longitudinal movement of the projectile in the cell (Fig. 5). The mechanism for supplying charges from the ground 10 (Fig. 6) is located outside the tower and is made with the top location of the drive 15 and the circuit 16, moving the charge into the fighting compartment. The upper arrangement of the actuator 15 and the circuit 16 provides such a position of the mechanism for supplying a charge from the soil 10 such that the loading line to the mechanism is reduced by at least 150 mm and is shifted closer to the side and to the stern. Autonomous gas turbine power unit 9, installed in the tower 4, is made with a device for conditioning and heating 17 air in the inhabited compartment.

In the inventive product there are two similar in design FVU 18. They are located in the rear of the tower on top of each other in the compartment for placement of filtering units. Each FVU 18 (Fig. 7) consists of a pipe with a valve 19, a supercharger 20, a filter-absorber 21, an electromechanism 22 with a control actuator for the valve 19 and a supercharger 20, a sensor 23, an electromagnet 24, connecting pipes and mounting parts. FVU 18 (Fig. 8) are switched on remotely: forcibly from the button or automatically when the charging cycle starts, while the electromechanism 22 is activated, the retracting rod with a groove 25, which rotates the lever 26 and moves the valve stem 19 through the cable 27, compressing the valve spring 19. The rod with the groove 25 of the electromechanism 22 rotates the lever 26 and puts it on the stopper mounted on the rod of the electromagnet 24. After that, the rod with the groove 25 of the electromagnetism 22 returns to its original position, and the lever will be held by the stopper of the electromagnet 24. Valve 19, moving When it opens, it opens the air intake valve and simultaneously acts on the sensor 23, by the signal of which the supercharger 20 starts. The HLF is switched off by force from the button or automatically by the signal of the system of protection against weapons of mass destruction, while the power is supplied to the electromagnet 24, which retracts the rod with the stopper, releases the lever 26 connected by a cable 27 to a valve 19, which closes under the action of a spring. When closing, the valve 19 acts on the sensor 23, at the signal from which the supercharger 20 stops.

The operation of the 155 mm caliber cartridge-free self-propelled artillery gun is similar to the operation of the modernized 152 mm 2S19M1 Msta-S self-propelled artillery gun.

The technical efficiency of the proposed utility model is as follows:

1. An increase in the elevation angle by 2 ° is ensured by eliminating in the casing of the breech of the gun of the conveyor belt the removal of the fireproof sleeve.

2. Installation of an internal combustion engine with a capacity of 1000 hp will lead to an increase in specific power and, as a consequence, an increase in speed and mobility indicators of self-propelled artillery guns.

3. The upper arrangement of the drive and the chain moving the charge to the fighting compartment ensures that the mechanism for supplying charges from the ground is such that the loading line to the mechanism is reduced by at least 150 mm and is shifted closer to the side and to the stern, which ensures ease of loading and improves access to the mechanism.

4. Installation of an autonomous gas-turbine power supply unit with an air conditioning and heating device will provide comfortable conditions in the inhabited compartment for operation in the Far North and southern regions.

5. The installation in the cells of the mechanized laying of movable elements, limiting the longitudinal movement of the projectile in the cell, ensures the placement and reliable retention of shells of various lengths.
