Description

The invention relates to the field of unitary or separate loading ammunition stabilized by plumage and can be used to localize forest and steppe fires, as well as burning oil and all oil products, by delivering ammunition to the target from large-caliber smooth-bore weapons.

At present, the problem of localizing and extinguishing fires is not only relevant, but also timely, since in recent years the number of fires has only increased, and their consequences have become burdensome for any state. As the experience of extinguishing fires shows, the safe state of the fire zone is extended in time until it is eliminated. At the same time, the possibility of ground technical equipment approaching the fire zone for extinguishing fire remains dangerous, both for personnel and for the fire extinguishing equipment themselves. According to the authors of the claimed invention, for the general safety and operational localization of a fire, it is necessary to develop ammunition with fire extinguishing equipment, which allows in a short time to deliver and distribute equipment in the fire zone and prevent its spread.

As fire-extinguishing equipment in ammunition for the localization of the above-mentioned types of fires, it is advisable to use sprayed water, which is the most representative, cheap and affordable extinguishing agent. Crushed into tiny droplets, water has a large surface with a small mass, due to which it is able to quickly heat up and evaporate, taking away heat from a burning object and lowering the oxygen content in the air adjacent to the combustion zone. A "steam blanket" is formed, which isolates burning objects from the influx of oxygen from the atmosphere. In addition, sprayed water or steam, mixing with the top layer of heavy grades of petroleum products, forms a non-flammable emulsion in the form of a film, which also insulates the burning surface from air. In winter conditions, it is possible to lower the freezing point of water by dissolving common salt, calcium chloride and magnesium in it, which will practically not affect the increase in the viscosity of the aqueous solution (Kurbatsky M.P. Technique and tactics for extinguishing forest fires. - M .: Military publishing house, 1962. - 170 p.; Shevchuk M.K. Incendiary means and protection against them. - M.: Military publishing house, 1961. - 120 p.).

The above data are the key to the development of the design of ammunition with fire extinguishing equipment.

Widespread use in practice of extinguishing fires has been received by such methods as undermining and spraying fire extinguishing compositions over a burning surface and during contact earth impact, used in ammunition and devices. Such well-known analogues include:

- "Fire-fighting rocket-propelled grenade" patent of the Russian Federation for the invention No. 442624, IPC A62C 3/02, A62C 19/00, F42B 30/04, 2012;

- "Fire-extinguishing device" RF patent for utility model No. 113155, IPC А62С 19/00, А62С 17/00, 2012;

- "Fire-extinguishing projectile" patent of the Russian Federation for the invention No. 2740594, IPC A62C 35/08.2021;

- “Fire extinguishing method (options) and device for its implementation” RF patent for invention No. 2288761, IPC А62С 3/02, F42B 12/46, А62С 19/00, А62С 27/00, F42B 5/03, 2006.

The common significant disadvantages of such fire extinguishing agents is the low efficiency of fire extinguishing compositions used in ammunition designs, since when using the above methods in ammunition, fire extinguishing compositions are sprayed in all directions from the ammunition as a result of the explosion, while losing the concentration of the extinguishing agent and the density of its distribution, and ascending air flows from the fire zone, having a high speed, carry away most of the fragmented compositions from the burning surface into the atmosphere, while leaving an insufficient proportion of the extinguishing agent for thermodynamic and chemical effects on the surface of the combustion zone.

Close in technical essence to the claimed technical solution are devices for extinguishing a fire with water using aviation fire extinguishing equipment, which include tanker aircraft and helicopters with pouring devices (Instructions for detecting and extinguishing forest fires. Order of the Federal Forestry of Russia dated June 30, 1995 No. 100. - M. - pp. 35-43, 66). Such aircraft include: a MI-8T helicopter with a device for dosing water intake and a remote control system for draining liquid with a lock for emergency discharge of the spillway device, as well as tanker aircraft (AN-2, AN-26P, AN-32P) and a seaplane Be-12P-200 with a minimum flight altitude when dropping water over a burning surface from 25 to 50 meters. As world practice shows, aviation means are the most effective and expedient in the fight against intense fires of rapid spread. A similar set of essential features of the analogue and the claimed invention include the general design of the purpose and implementation of the method of extinguishing a fire with water, along the burning edge from the height of a flying vehicle, as well as indirect, but still necessary design features, which include cylindrical water tanks and water remote control systems. plum. The reasons preventing the achievement of the technical result indicated below when using aviation fire extinguishing means are:

- significant financial and energy costs of the applied method;

- use of remote control systems for water discharge of high capacity and with irrational consumption;

- large volumetric and weight and size characteristics of the used cases and structural units that ensure the performance of the products in question;

- the need for special qualifications of pilots operating aircraft.

Also known from the prior art is "Ammunition with liquid equipment" according to the RF patent for the invention No. 2354921, IPC F42B 12/48, 2009.

Despite the fact that this invention, on the one hand, has a purpose unusual for extinguishing fires, and can be used to mask personnel and equipment, when setting up smoke and heat screens, as well as to defeat enemy personnel with toxic substances, on the other hand, principle of operation and technical device is the closest to the claimed technical solution and therefore chosen by the authors of the proposed invention as a prototype.

Ammunition with liquid equipment, containing a cylindrical body made in the form of a body of revolution around its axis of symmetry with an internal through cavity, on one side of which a fuse is installed, configured to initiate ignition of the expelling charge, and on the other side there is a bottom with a hole for pouring into it liquid equipment and with a hole for air to escape from it, while a plug is installed in the hole for filling the liquid, and a plug is installed in the air outlet hole, and in the internal through cavity of the body between the expelling charge and the liquid equipment it is installed with the possibility of moving along the axis of symmetry of the body diaphragm with radial seal. A rod is located in the internal through cavity of the housing, the axis of which is parallel to the axis of symmetry of the housing, and a hole for the rod is made in the bottom, in which a knockout plug is installed, while the rod is made of an upper cylinder of small diameter interacting with the upper end with the said diaphragm, and a lower cylinder of a larger diameter, interacting with the lower end with the above knockout plug.

(The above text requires clarification on the term "fuze" both for the prototype and for the claimed invention. Its correct name is considered to be a "remote fuse" having a fire chain, the initial element, which is an igniter cap, and the final element is a powder firecracker, which when interacting with intermediate elements, an igniter impulse is generated to activate the expelling charge at a given point of the trajectory.Also, in the design of the prototype, there is no structural design of a cylindrical body with a fairing, in which a remote fuse is located.Such a structural element as a fairing is a mandatory design in the designs of ammunition using remote fuses Therefore, throughout the description of the invention, the terms "remote fuse" and "radome" will be used.)

The task of this technical solution was to obtain particles of a certain dispersion when spraying liquid equipment ammunition.

The principle of operation of ammunition with liquid equipment is as follows. After the ammunition is fired from the gun at a certain point in the trajectory, a remote fuse is fired located in the fairing of the cylindrical body, initiating the ignition of the expelling charge. The resulting gases exert pressure on the diaphragm, which in turn acts on the knockout plug through the rod. When a certain pressure of the rod on the knockout plug is reached, it is released. The gas formed from the combustion of the expelling charge begins to expand, which leads to the movement of the diaphragm and the rod along the axis of symmetry of the body. When the lower cylinder of a larger diameter of the rod passes through the hole for the knockout plug, an annular gap is formed. Spraying the liquid through the annular gap makes it possible to obtain particles of a certain dispersion, which are more evenly distributed along the section of the munition's flight path.

The common features of the claimed invention are the presence in the prototype of a cylindrical body made in the form of a body of rotation around its axis of symmetry with an internal through cavity, on one side of which a fairing is made, in which a remote fuse is installed, configured to initiate ignition of the expelling charge, on the other side in the inner the bottom is installed through the cavity, a diaphragm with a radial seal, made with the possibility of moving along the axis of symmetry of the body, a rod, the axis of which is parallel to the axis of symmetry of the body, and a knockout plug.

The reasons preventing the achievement of the following technical result when using the prototype include:

- unusual for the claimed invention, the principle of spraying liquid equipment in the design of the ammunition;

- the problem solved by the prototype does not meet the problem of extinguishing fires;

- the use of aggressive toxic liquid compositions as equipment in ammunition that have a negative impact on both human health and the environment;

- the stability of the flight of the ammunition is provided only by gyroscopic stabilization due to rotation at a high angular velocity.

The objective of the claimed invention is the development of the design of the ammunition of the target direction for the operational localization of fires of various classes along the edge of the fire, by performing the following technical capabilities to ensure:

- static stability of the ammunition throughout the trajectory of its flight;

- reducing the speed of the munition at a specific point in its flight with the simultaneous start of dispersion of water over the burning surface, with the continuation of its spraying in the direction of the munition along the descending branch of the trajectory.

The problem is solved due to the fact that in the design of the closest analogue, containing a cylindrical body made in the form of a body of revolution around its axis of symmetry with an internal through cavity, on one side of which a fairing is made, in which a remote fuse is installed, made with the possibility of initiating the ignition of a knockout fuse. charge, and on the other hand in the internal through cavity there is a bottom, a diaphragm with a radial seal, made with the possibility of moving along the axis of symmetry of the body, a rod, the axis of which is parallel to the axis of symmetry of the body and a knockout plug, according to the invention, the following distinguishing features are given:

- a cylindrical body of the ammunition with two built-in obturating belts located on the centering bulges, made with the possibility of placing behind the bottom of the body of the stacking unit and ejection of a domed parachute with a pole hole, and water is used as liquid equipment in the internal through cavity, four flow channels are built into the bottom body channels arranged coaxially, one against the other, in a plus shape, and ending with a conical slot with a closed knockout plug, made with the possibility of jet distribution and radial dispersion of water into the air space from the side surface of the munition body;

- openings for pouring liquid with a plug and air outlet are placed linearly on the side surface of the body and are made with threaded metal caps, while the rod is made in the form of a tube with the possibility of additional passage of powder gases through it from the expelling charge to the parachute location unit, consisting of a piston, made with an upper end cavity, sling fasteners, a stacked dome, a retaining ring and a kick-out protective membrane;

- on the side surface of the body of the ammunition, between the channels along their center, are laid horizontally, relative to the axis of the ammunition in elongated grooves, four blades of the stabilizer of the axial attachment, having the shape of a rectangle with a beveled profile of the angle of attack of 1.5 degrees.

The distinctive features of the proposed technical solution made it possible to develop the design of ammunition with fire extinguishing equipment that ensures the fulfillment of the task, and a new set of structural elements, as well as the presence of connections between them, makes it possible, in particular, due to:

- placement of the stabilizer in the tail section of the munition (as close as possible to the bottom cut), ensure the greatest deviation of the center of pressure from the center of mass and thereby acquire stable movement along the entire trajectory with a minimum area of its blades, and the use of a stabilizer with four blades of axial attachment with beveled profile of the angle of attack of 1.5 degrees located in the center between the flow channels, allows the ammunition to acquire a slight rotation when exiting the smoothbore barrel, designed to compensate for the eccentricity of the thrust vector, geometry inaccuracies of the blades and other factors that cause one-sided deviation of the ammunition from the calculated trajectory (elimination yaw effect), while providing aerodynamic and gyroscopic flight stabilization. It is recommended that titanium, the melting point of which is 1660°C, be used as a material for the manufacture of stabilizer blades;

- replacement of the leading belt in the prototype with two obturating belts located on the centering bulges of the ammunition body, ensures reliable centering of the ammunition in the smoothbore bore of the barrel, while excluding the breakthrough of powder gases coming from the propellant charge, and the horizontal stacking of four blades in elongated grooves on the lower side the surface of the body of the ammunition has a similar height of the obturator bands and provides additional centering protrusions to improve the stability of the passage of the ammunition through the bore, and also acts as brake rings for the ammunition to reduce the flight speed;

- use as a liquid equipment - water will allow you to perform the task of promptly localizing a fire without any special financial and labor costs, due to the fact that it is the most effective, affordable and most common means of extinguishing fires of varying intensity and does not belong to toxic compounds that have a harmful impact on human health and the environment. Water can be used from the water bodies closest to the fire source (rivers, lakes, fire reservoirs, etc.), and in their absence - specially delivered in fire trucks and various containers. The main feature of the use of water in ammunition is that it is constantly "at hand" of fire brigades and does not require additional delivery of chemical reagents to the fire zone, and the preparation of fire extinguishing compositions for use as equipment;

- replacement of holes in the bottom body, for filling liquid with a plug and air outlet with a plug, with threaded metal caps placed linearly on the outer body of the ammunition, makes it much more rational to fill water into the internal through cavity of the ammunition, while ensuring ease of filling (for example, through the funnel) and the exclusion of the formation of an air cushion, and the manufacture of metal screw caps corresponds to the intended purpose of the ammunition and its performance at high ambient temperatures;

- the execution of the rod in the form of a tube ensures the passage through its internal volume of powder gases coming from the actuation of the expelling charge into the parachute stowage unit, and due to the pressure formed in the upper end cavity of the piston, set it in motion to eject the parachute into the airspace, while before its release, the protective membrane is fired, and the retaining ring holds the piston with slender fasteners when the parachute canopy opens;

- the use of a domed parachute with a pole hole, allows you to solve the problem of reducing the speed of the flight of ammunition starting from a specific point of operation of the remote fuse and the activation of the parachute. The necessary put forward requirement for a canopy parachute that provides a decrease in the speed of the ammunition is its sufficient filling and increased stability of both the parachute itself and the ammunition body throughout the entire flight along the descending branch of the trajectory. Fulfillment of this requirement makes it possible to obtain the required density of the liquid aerosol above the burning surface. It is known that in the case when the parachute dome has no permeability, the parachute system behaves as a substantially nonlinear system, that is, due to the formation of oscillatory factors and the resulting destabilizing (overturning) moments, the ammunition swings with loss of flight stability. This process can be avoided or excluded by the pole holes made in the central part of the dome, and the diameter of the pole hole of the parachute must be no less than the size of the caliber of the ammunition. This size of the pole hole passes through itself the aerodynamic wake of the ammunition body, excluding its chaotic buildup and provides the minimum drag coefficient of the parachute itself. Also for this purpose, the arrangement along the circular edge of the parachute line mounts, located on the lower end of the piston, is intended. In order to reduce the speed of the ammunition without changing the given trajectory, the geometric parameters of the canopy must be much smaller than those of braking and rescue parachutes, and when determining them, it is necessary to take into account the drag force of the dome area without a pole hole, the amplitude of oscillations and the balancing value of the angle of attack, affecting at the angle of approach of the ammunition to the target. It is likely that such a parachute, when deployed, takes the form of an annular stabilizer, which is characterized by the angle of installation of the profile relative to the longitudinal axis of symmetry, the bottom radius of the circle formed and the elongation of the profile, which in turn will additionally ensure the static stability of the ammunition and the parachute with a decrease in flight speed. It is recommended to impregnate the lines and the parachute dome itself with refractory substances;

The use of a diaphragm with a radial seal moving along the rod makes it possible to seal the volume of the internal through cavity from the passage of water and at the same time, due to the incoming pressure of powder gases from the expelling charge, to displace water from the through cavity, with its simultaneous and equal distribution through four channels located on a plus shape in the bottom case;

- the use of flow channels ending in a conical slot with a closed knockout plug, provides four high-speed radial dispersion jets from the side surface of the ammunition body and due to its rotation, all jets are swirled with the formation of a volumetric vortex flow settling on the burning surface. Simultaneous ejection of water from four channels in mutually opposite directions from the ammunition body at the same speed compensates for the destabilizing (overturning) moment of the ammunition body during the opening of the parachute and maintains its stability on a given flight path. Four knockout plugs are designed to keep water equipment until the remote fuse is triggered.

It is also necessary to point out that the connections between the structural elements and their performance, in addition to the placement of the stabilizer and the use of obturator belts, provide the main relationship between the activation of the remote fuse and the expelling charge. In this case, the required pressure of the propellant gases of the expelling charge must be sufficient to eject a parachute with a pole hole and uniformly move the membrane along the rod, as well as release four expelling plugs and release water into the airspace. In the claimed ammunition, it is recommended to use a 328 V remote fuse of a semi-safety type designed to issue a fire pulse after a set time of remote action. Management and input of information about the required time is carried out via an inductive communication line placed on the command vehicle, and black powder, type DRP-2 or pyroxylin type Sf033, is used as fuel for the expelling charge. It is possible to increase the operating time of the expelling charge by using equilibrium beams (packets) of variable charges in its body, stacked in series one after the other vertically. The implementation of such a constructive solution increases the size of the fire localization area. (Selivanov V.V. Ammunition: Volume 2. - M .: MSTU named after N.E.

The technical result of the proposed invention is a quick and unhindered localization of a fire, including the possibility of its implementation from closed positions, which reduces the likelihood of damage to fire brigades involved in this process, and also minimizes financial labor costs for the elimination of such emergencies.

23 - centering thickening of the cylindrical body of the ammunition (Fig. 1, 2);

24 - cylindrical body of the ammunition (Fig. 1, 2, 3, 4).

The claimed ammunition contains a cylindrical body 24, which is a body of rotation around its axis of symmetry, with an internal through cavity filled with water 15, on one side of which a fairing 2 is made, in front of which a remote fuse 1 is installed, initiating ignition of the expelling charge 11, and on the other bottom 6 is installed on the side, in the body of which there are four flow channels with a narrowed conical slot 7, closed with knock-out plugs 16. On the outer side of the cylindrical body 2 there are linear metal covers for filling water 4 and air outlet 5, as well as two thickenings 23. In the internal through cavity 15, a rod 14 is placed in the center, made in the form of a tube with the possibility of passing through it powder gases coming from the expelling charge 11 into the parachute location unit, consisting of a piston 18 with an upper end cavity 17, slender fastenings 19 placed along the circular edge of the lower end of the piston 18, laying the dome with a polar hole 8, the retaining ring 20 and the expelling protective membrane 21. Also, in the internal through cavity 15 in front of the expelling charge 11, a diaphragm 12 with a radial seal 13 is built in, which can move along the rod 14 and distributing water through four flow channels 7, with an equivalent speed, and the flow channels 7 are placed in the body of the bottom 6 coaxially one against the other in a plus shape. On the lower side surface of the cylindrical body 24 with the possibility of its slow rotation on the trajectory, between the flow channels 7 along their center, four blades of the stabilizer 9 of the axial fastening 10 having the shape of a rectangle with a beveled angle of attack profile of 1.5 degrees are laid horizontally in the elongated grooves 22.

The above ammunition works as follows. Before using ammunition, the fire situation is monitored. The coordinates of the fire, the speed of its propagation and the distance to the leading edge of combustion are determined. Ammunition is filled with water and the cylindrical body is closed with threaded caps. Knowing the flight speed of the ammunition before it decreases and the distance to the burning edge, the command vehicle calculates the cocking time of the remote fuse on the trajectory, carried out via an inductive communication line. Equipped ammunition is fired from a large-caliber smoothbore barrel. At the moment of exit from the trunk, the blades of the stabilizer with a beveled profile are opened, providing aerodynamic and gyroscopic stabilization of the flight along the entire trajectory. Reaching a predetermined point of application, the design of the ammunition, due to the operation of a remote fuse, simultaneously reduces the flight speed by ejecting a parachute with a pole hole and works to disperse water into the airspace. The ejection of a parachute from a cylindrical body is carried out in the following sequence. The powder gases coming from the expelling charge pass through the internal volume of the rod into the upper end cavity of the piston and squeeze the piston to the retaining ring. In this case, the expelling protective membrane is torn off, and the dome with the pole hole is thrown out of its packing into the airspace. Retention and locking of the parachute is ensured by slender fasteners located along the circular edge of the lower end of the piston and a retaining ring. Similarly, at the same time, under the influence of the same powder gases coming from the expelling charge, the diaphragm with a radial seal displaces water from the internal through cavity of the cylindrical body and distributes it through four flow channels with a narrowed conical gap. Due to the formed liquid pressure in the flow channels, the knockout plugs are released, followed by the release of a high-speed water jet outside the cylindrical body, while producing a radial distribution and swirling of the jet vortex flow, forming a volumetric liquid spray behind the munition along the section of the descending branch of the trajectory. The settled liquid, under the influence of convection currents from the burning surface, turns the vortex flow of water into an aerosol, and then into a vapor cloud, which isolates the burning surface from the influx of oxygen from the atmosphere, and when mixed with the top layer of heavy grades of oil products, forms a non-flammable emulsion in the form of a film also insulating fire area from air access, while extinguishing the flame and sharply reducing its temperature. After the localization of the fire, technical means and fire brigades are allowed into its zone to eliminate and completely stop the combustion process.

Thus, the proposed ammunition with fire extinguishing equipment allows, at a safe distance from the fire zone, in a short time, to localize fires with minimal risk to the lives of personnel involved in extinguishing the fire, as well as reduce the cost and labor costs for conducting such rescue operations. events.

The inventive ammunition with fire-extinguishing equipment can be delivered to the fire zone not only from cannon artillery, but also by means of multi-barreled launchers, as well as unmanned aerial vehicles, for which it is necessary to install an expelling propulsion system on the end end of the cylindrical body, which is separated when fired.
