Abstract

FIELD: weapons and ammunition.

SUBSTANCE: artillery barrel with universal external cooling utilises mechanical energy of barrel recoil when firing, driving a device comprising corrugated air and hydraulic cylinders and springs, which provides for extrusion and forced convection of a liquid coolant from the left bed into a detachable jacket of forced liquid cooling of the barrel at the side of a muzzle end with further discharge into the initial corrugated volume in the left bed. The device pumps air into a balloon in the left bed with its further distribution to blow the barrel after each shot, and to blow the detachable jacket of forced liquid cooling upon completion of field or mock firing. It is possible to use the right bed with arrangement of the same volumes in it for air and liquid.

EFFECT: higher reliability, persistence and combat effectiveness of barrel artillery.

Description

The invention relates to the field of artillery barrel cooling. When firing, the walls of the artillery barrel heat and overheat, which leads to negative processes: to bending the barrel with a further decrease in range, accuracy, accuracy and accuracy of fire; to the occurrence of microcracks with the possibility of complete destruction of the trunk; to mechanical wear and reduction of the resource and reliability of the barrel; to a forced ceasefire for 60-120 minutes in order to cool the barrel, which significantly reduces combat effectiveness, and in addition, there is a real danger of detecting a firing position, destruction of guns and all personnel from the enemy; and other negative consequences [1, 2].

Issues of the quickest barrel cooling are relevant at the present time, when local wars, ethnic conflicts and terrorist acts occur [3-5].

One of the effective ways of cooling an artillery barrel is liquid forced cooling, where water, special cooling liquids, and other liquids can serve as a cooler. Such a system allows firing virtually without stops to cool the barrel.

Consider a brief description of the drawings shown in figures 1-8.

Figure 1 schematically shows a towed uncooled gun, where 1 is the barrel, 2 is the cradle, 3 is the right wheel, 4 is the right frame, 5 is the bolt, 6 is the left frame, 7 is the left wheel.

Figure 2 shows a cooled gun with forced liquid cooling of the barrel, where 1 is a barrel with a liquid cooling jacket, 8 is a casing, 9 is a tank, 10 is an electric motor, 11 is an electric pump, 12 is a radiator, 13 is a fan, 14 is a hose, 15 - connecting pipes.

Figure 3 shows a cross-section of artstvol along section AA (see figure 2), where the channels of the stationary jacket of the forced liquid cooling of the barrel are visible.

Figure 4 schematically shows artillery with the utilization of the mechanical energy of the recoil of the barrel during firing and providing external forced (liquid, air) cooling of the barrel, where 1 is the barrel, 2 is the cradle, 3 is the right wheel, 4 is the right frame, 5 is the shutter, 6 - left frame, 7 - left wheel, 16 - a special device for creating air and hydraulic pressure, 17 - lever on the moving part of the barrel, 18 - input manifold of the cooling jacket, 19 - removable cooling jacket, 20 - output manifold of the cooling jacket, 21 - air cylinder, 22 - capacity d I liquid cooler, 23 - a spring.

Figure 5 shows a structural diagram of a special device in the initial state before the shot, which is indicated in figure 4 by the number 16. This special device contains the following elements: 24 - housing of the movable top cover, 25 - thrust plate, 26 - main working spring, 27 - corrugated bellows-type air tank, 28 - right retainer for holding the cover of the working cup, 29 - housing of the stationary working cup, 30 - supporting movable plate, 31 - corrugated fluid container of the bellows type, 32 - working spring, 33 - reverse w fluid valve, 34 — output fluid channel, 35 — fluid inlet channel, 36 — fixed motionless bottom plate, 37 — fluid check valve, 38 — left locking cup retainer, 39 — check air valve, 40 — left air hole, 41 - outlet air channel, 42 - right air hole.

Figure 6 shows a special device immediately after the shot and recoil of the barrel (spring 26 and air corrugated container in a compressed state).

Figure 7 shows a special device a few seconds after the shot and recoil of the barrel (the spring 26 and the air corrugated container 27 are in the initial expanded state, and the springs 32 and the corrugated liquid container 31 are in a compressed state).

On Fig schematically shows a structural diagram of the barrel 1, where 18 is the input manifold of the cooling jacket, 19 is a removable jacket of liquid forced cooling, 20 is the output manifold of the cooling jacket, 43 are the transverse round ribs of the outer part of the cooling jacket.

An analogue of an artillery uncooled gun can serve as the gun shown in figure 1 [2], which contains the following main fixed and movable elements when firing, inherent in all towed uncooled artillery guns: barrel 1 (moving part), cradle 2 (fixed part), right wheel 3, right frame 4, shutter 5 (moving part), left frame 6, left wheel 7.

As a prototype, you can consider the cooled gun, shown in figure 2 [1]. This design contains the following parts of the forced cooling system: barrel 1, casing 8, reservoir 9, electric motor 10, electric pump 11, radiator 12, fan 13, hose 14, connecting pipes 15.

This design of the system of forced cooling of the barrel has several disadvantages (see figure 2) [6, 7]:

a) the need for an electric motor 10, an electric pump 11, a fan 13, a radiator 12, a power source, and a special coolant;

b) small: efficiency, reliability, reliability, resource, safety, invulnerability, survivability, etc .;

c) large: economic, time and technological costs in the manufacture, operation and repair;

d) the cooling jacket (see figure 3) is stationary, expensive and difficult to manufacture, expensive and inconvenient for maintenance, expensive and practically unrepairable;

e) the mechanical recoil energy of the barrel is not used when firing to provide forced cooling of the barrel.

The invention is proposed, which utilizes the mechanical energy of the recoil of the barrel when firing, shown in figure 4, which consists of the following main movable and fixed elements inherent in all designs of the barrel artillery, this is barrel 1 (moving part), cradle 2 (fixed part) , right 3 and left 7 wheels, left 6 and right 4 beds, shutter 5 (moving part). Additional elements of the invention (see figure 4) is a special device for creating air and hydraulic pressure 16, located on a fixed part (cradle) 2; a lever 17 mounted on the movable part of the barrel 1; removable cooling shirt 19; an inlet manifold 18 for supplying a cooler to a cooling jacket; output collector 20 for collecting a cooler with its further transfer to a corrugated container in a glass; cylinder 21 for the accumulation of compressed air; corrugated tank 22 bellows type for liquid cooler in the left frame; spring 23 for preloaded corrugated container 22 with a liquid cooler.

A special device 16 (see figure 4) for creating air and hydraulic pressures contains the following parts (see figure 5): the housing 24 of the movable top cover; thrust plate 25; main working spring 26; corrugated bellows-type container 27 for intake and extrusion of air into the cylinder 21 (see figure 4); right 28 and left 38 retainers hold the lid of the working glass after a shot in a compressed state; the housing of the stationary working glass 29; supporting movable plate 30 for working springs in a glass; bellows-type corrugated tank 31 for liquid cooler; working spring 32; check valve 33 for supplying a liquid cooler to the cooling jacket; a channel (tube) 34 for supplying a liquid cooler to the cooling jacket; a channel (tube) 35 for supplying a liquid cooler from the tank 22 (see Fig. 4) of the left bed 6 to the tank 31 of the cup 29; supporting fixed lower plate 36 of the glass 29; check valve 37 for supplying a liquid cooler from the tank 22 (see Fig. 4) of the bed 6 to the corrugated tank 31 of the cup 29; air check valve 39 intake and extrusion of air into the cylinder 21 (see figure 4) in the frame 6; left (40) and right (42) through holes for air balance inside the housing of the special device 16 (see figure 4); channel (tube) 41 of the output air channel for supplying compressed air to the cylinder 21 (see figure 4) in the frame 6.

It should be noted that the removable liquid-cooled jacket 19 of the barrel 1 (see FIG. 4) of stainless steel may have an outer surface in the form of a transverse round copper fins 43, as shown in FIG. This allows you to further accelerate the process of cooling the barrel [6]. This type of fin free cooling (without the presence of a liquid cooler) can reduce the barrel cooling time from 120 minutes to 30 minutes, and if instead of a liquid cooler in the channels of the cooling system pump external air (for example, from cylinder 21 (see figure 4)), while barrel cooling time can be reduced to 10-15 minutes. This cooling method is backup, for example, in the event of an emergency and breakdown of the liquid cooling system or in the absence of a liquid cooler at the position. The air accumulated in the cylinder 21 (see Fig. 4) can also be used for other purposes, for example, for air starting piston internal combustion engines (ICE) of self-propelled artillery installations, armored vehicles, mobile diesel power plants, and other technical systems.

Consider the invention in statics (before firing). Before firing, it is necessary to fill the cooling system with a liquid cooler, which is poured (see Fig. 4) into a removable cooling jacket 19 through the inlet manifold 18, filling the outlet manifold 20 and corrugated container 31 in the fixed cup 29 (see Fig. 5). The liquid cooler also fills the corrugated tank 22 in the left frame 6 (see figure 4).

The initial position of the working device 16 (see Fig. 4) before firing is shown in detail in Fig. 5, where the main working spring 26 is in an expanded state, the corrugated container 27 for taking and extruding a portion of air is in the same state, the spring 32 is corrugated capacity 31 for extruding a liquid cooler. In tanks 21, 27 contains air of normal external pressure, in tanks 22, 31 - a liquid cooler without additional pressure (see figure 4, 5).

The lever 17 (see figure 4), rigidly mounted on the movable part of the gun (on the barrel), fits snugly on the movable cover 24 (see figure 5) of the working special device 16 (see figure 4).

When fired (in dynamics), the following processes occur:

a) a sharp and powerful recoil back of the barrel 1 (see figure 4) moves using the lever 17 the cover 24 (see figure 5) of the working special device 16 in a compressed state;

b) the cover 24 (see Fig.6), compressing the main spring 26 and the corrugated air tank 27, is fixed by the protrusions of the thrust plate 25 for the latches 28.38;

c) a portion of compressed air from the tank 27 (see Fig.6) entered the cylinder 21 (see Fig.4), from which it partially went to purge the bore after the shot;

d) the main working spring 26 (see Fig.6) begins to expand, moving the base plate 30 to the lower position, compressing the spring 32 and the corrugated container 31 with a liquid cooler, while the air corrugated container 27 is unclenched (see Fig.7) and through a non-return air valve 39 (see Fig. 5), a new portion of air is taken;

e) a liquid cooler from the corrugated container 31 (see Fig. 7) under pressure through a check valve 33 (see Fig. 5) and a channel (tube) 34 enters the inlet manifold 18 (see Fig. 4), moving all previously filled liquid and providing forced convection in the cooling jacket 19, then entering the output manifold 20, and at the end entering the corrugated container 22 (see Fig. 4) in the left frame 6;

e) when the liquid cooler enters the corrugated container 22 (see Fig. 4) in the left frame 6, this container begins to expand and compress the spring 23;

g) after the equilibrium of the entire hydraulic cooling system is established, the compressed spring 23 will begin to expand and compress the corrugated container 22, and the liquid cooler through the channel (tube) 35 through the check valve 37 (see Fig. 5) will begin to flow into the corrugated container 31 (see Fig. .7);

h) at the same time, the spring 32 begins to fully unclench (see Fig. 7), which will expand the corrugated container 31, lift the base plate 30 together with the corrugated container 27, the spring 26 and the thrust plate 25 (the latches 28, 38 are automatically removed) until the outer surface of the cover 24 (see FIG. 7) is in full contact with the surface of the lever 17 (see FIG. 4), after which the system is ready again for the next shot.

Such a duty cycle occurs after each shot of the gun. It should be noted that the main working spring 26 (see Fig. 5, 6, 7) not only provides pumping of the liquid cooler through the channels of the cooling jacket with its further return to the corrugated container 22 in the left frame 6 (see Fig. 4), but and creates and maintains a critical pressure zone in the cooling jacket and throughout the system, where the coefficient of thermophysical properties (TFS) "B" is able to increase the coefficient of heat transfer to liquid hydrocarbon fuels (UVH) and coolers (SVO) by 2-3 times [8, 9 ]. The present invention proposes the use of liquid UVG (SVR) as liquid coolers, for example diesel fuel, which is always available in military vehicles, in self-propelled artillery installations (self-propelled guns), etc.

This liquid barrel cooling system with the utilization of the barrel’s mechanical recoil energy during firing is efficient, economical and reliable.

In the absence of liquid UVG (SVR), this system allows the use of air from cylinder 22 as a cooler (see Fig. 4). In this case, before firing, it is necessary: 1) to connect the air channels to the inlet manifold 18 (see Fig. 4), and leave the outlet manifold 20 open - to discharge air into the atmosphere after passing the cooling jacket; 2) the operation of the corrugated container 31 (see FIGS. 5, 6, 7) and check valves 33, 37 should be used for intake and supply of air into the common air system (into cylinder 22 (see FIG. 4) or into the barrel bore system after firing), for which it is necessary to open the air to the tube 35 and switch the tube 34 to the air system.

To improve the efficiency and survivability of this artstvol cooling system, it can be proposed to place the same system in the right frame with a common working special device 16 (see figure 4) or with the same device, but located to the right of the barrel. The following options are available for pumping a liquid cooler: a) from the left bed through the barrel cooling jacket to the right; b) from the right bed - through the barrel cooling jacket - to the left; c) from the left bed - through the barrel cooling jacket - to the left; d) from the right bed - through the barrel cooling jacket - to the right.

In emergency situations and failure of the liquid cooling system, you can switch to air cooling, using either the left air system or only the right one. But to increase the efficiency of air cooling, it is possible to use both air systems at once.

It is assumed that removable liquid (and hybrid) cooling shirts will constructively consist of sectors whose length and quantity will depend on the specific barrel length of the gun under consideration. The most optimal length of one sector is a length of 50-80 cm. Each removable sector should have threaded sockets with gaskets for fastening the inlet and outlet hydraulic connecting pipes, marking their mounting location on the trunk (which is very important, especially for tapering trunks), and also less than two special locks couplers.

Before training (combat) firing, it is necessary to firmly fix and tighten all sectors of the detachable cooling shirt and tighten the ties on the barrel, as air gaps of 1-5 mm have a negative effect on the barrel cooling rate as a whole due to poor thermal conductivity of the air. It is also necessary to ensure a reliable connection of all hydraulic and pneumatic channels and tubes of sectors, collectors and devices of the entire barrel cooling system. Removable hybrid sector-type cooling shirts are the most efficient, reliable and convenient to operate, and the possibility of affordable and high-quality preventive maintenance and repair work is opened, which is almost impossible with stationary cooling shirts.

The scientific novelty of this invention are:

a) the utilization of the mechanical energy of the recoil of the artillery barrel during firing in order to provide forced (liquid or air) cooling, which eliminates the need for an electric motor, electric pump, fan, power supply, etc.

b) the use of liquid hydrocarbon fuels (diesel fuel) instead of water or special coolants;

c) the creation and maintenance of a critical pressure zone in the cooling jacket, which automatically (at no cost) due to the thermophysical properties of the liquid hydrocarbon fuel (cooler) increases the heat transfer coefficient to the liquid hydrocarbon fuel (cooler) by 2–3 times;

d) the hydraulic (and pneumatic) barrel cooling system is devoid of problems associated with hydraulic (and pneumatic) pistons and cylinders by using movable corrugated bellows-type volumes and springs;

d) a special device 16 (see figure 4), capable of:

provide forced convection of the liquid cooler in the cooling jacket in the critical pressure zone;

accumulate compressed air to purge the barrel after each shot to purge and remove residual liquid cooler after training or live firing, to create forced convection of air in the cooling jacket in emergency situations or in the absence of a liquid cooler, to refuel air balloons for launching diesel ICE self-propelled guns, armored vehicles, special cars, mobile diesel power plants and other technical systems;

f) placement of hydraulic and pneumatic tanks of the cooling system in either the left, or right, or in both beds of the artillery gun (i.e. there is no need to have a special tank and place it next to the gun, as shown in figure 2);

g) a hybrid detachable cooling jacket of a sector type (see Fig. 8) (its advantages were described earlier); such designs for barrel artillery do not exist;

h) barrel cooling system, which allows:

in the presence of a liquid hydrocarbon cooler, fire without interruptions to cool the barrel;

in the absence of a liquid cooler or in emergency situations and breakdowns of the hydraulic system, cool the barrel with forced convection of air in the channels of the cooling jacket, which reduces the standard barrel cooling time from 120 minutes to 10-15 minutes;

in case of failure of the entire system (liquid and air) of forced barrel cooling, cool the barrel with the outer round transverse fins of the hybrid cooling jacket, which reduces the standard barrel cooling time from 120 minutes to 30 minutes.

Given the above material, it is possible in a more specific and correct form to propose an artillery barrel with universal external cooling, consisting of (see FIG. 2) a casing 8, a reservoir 9, an electric motor 10, an electric pump 11, a radiator 12, a fan 13, a hose 14, connecting nozzles 15, a power source, characterized in that:

forced liquid cooling of the barrel is provided by the utilization of the mechanical energy of the recoil of the barrel when fired;

utilization of the barrel’s recoil mechanical energy during firing is carried out by a special device 16 (see Fig. 4), mounted on the fixed part of the gun, and by a lever 17, mounted on the moving part of the barrel;

as a liquid cooler, liquid hydrocarbon fuel, for example diesel fuel, is used;

in the liquid cooling jacket 19 (see FIG. 4), a critical pressure zone is created and maintained;

the utilization of the barrel’s mechanical energy during firing is also used to accumulate compressed air with its further distribution: to purge the bore after the shot; for purging and removing liquid cooler from the cooling system after training (or combat) firing is completed;

the liquid cooling jacket is removable, sector type, structurally has an outer round transverse finning 43 and is hybrid (with the possibility of natural external and forced liquid cooling) (see Fig. 8);

in the absence of a liquid cooler or in emergency situations, for example, when the hydraulic cooling system fails, instead of a liquid cooler in the channels of a liquid barrel cooling jacket, forced convection of compressed air can be used;

corrugated container (see figure 4) 22 for a liquid cooler and a cylinder 21 for compressed air are located either in the left 6, or in the right 4, or in both artillery beds;

the supply of liquid cooler is carried out from the corrugated container (see figure 4) 22 left 6 or right 4 bed;

compressed air is supplied from the cylinder (see Fig. 4) 21 left 6 or right 4 beds, and in emergency situations, when using compressed air in the channels of the cooling jacket instead of the liquid cooler - immediately from two cylinders of both frames;

the liquid cooler after passing through the cooling jacket returns to the corrugated container 22 (see figure 4) left 6 or right 4 bed;

compressed air after passing through the channels of the cooling jacket (see figure 4) 19 is sent for discharge into the atmosphere;

all sectors of the hybrid detachable cooling jacket before the start of training (or combat) shooting should be firmly and firmly fixed on the barrel without air gaps with a tight connection of all hydraulic and air channels and tubes;

when using compressed air as a cooler, a preliminary reconfiguration of the cooling system must be carried out with the reinstallation of liquid and pneumatic inlet and outlet channels and tubes;

compressed air from air cylinders can also be used to ensure the launch of piston diesel internal combustion engines (ICE) of self-propelled artillery installations, armored vehicles, special vehicles, mobile (mobile) power plants and other technical systems.

The main advantage of the proposed new barrel cooling system is that it will allow firing with virtually no interruptions to cool it.

The use of this invention will significantly increase the resource, combat effectiveness, reliability, safety, survivability and cost-effectiveness of promising and modern domestic barrel artillery.
