Description

The invention relates to the field of pyrotechnics and can be used to obtain fireworks effects, to simulate explosions during theatrical and entertainment events to simulate the effect of a shot from a grenade launcher, to simulate the effect of a smoke screen, as well as to play paintball, airsoft and other military-sports games.

Known imitative pyrotechnic means - "explosive", consisting of a waterproof shell filled with black powder, and built into the shell of the means of ignition - igniter cord (Military Encyclopedic Dictionary, Moscow, "Eksmo", 2007, p. 169).

The disadvantage is an increased hazard class due to the use of black powder, which is a propellant in the device. In the case of an explosion near a standing person, it can harm him, which means that he cannot be used to play paintball, airsoft and other military sports games. Another disadvantage is the impossibility of long-range throwing, which is associated with the impossibility of using the well-known imitation pyrotechnic means by firing from grenade launchers.

The closest analogue, which is taken as a prototype, is a throwing device to simulate hostilities and a projectile to simulate hostilities. At the same time, the projectile device for imitating combat operations consists of directly the body of the projectile device, an articulated rifled barrel designed to accommodate a projectile in it, the projectile body comprising an upper cover with sealing rings, a valve with ball retainers, a stopper and a return spring, gas tank with charging valve. Regarding the projectile to simulate the fighting - it consists of the main body, an inertial-type initiating device built into it, a head fairing, an igniter with a pyrotechnic retarder, a drummer equipped with a safety spring, the main body, the body of the initiating device and the head fairing made of safety material . This projectile is an imitator grenade grenade. The surface of the housing has circumferentially inclined inclines with respect to the axis of the projectile to ensure rotation during movement. In this case, the projectile may contain light-noise, smoke or conditionally striking elements (Patent of the Russian Federation No. 81793, published on March 27, 2009. Bull. No. 9).

The disadvantages of the prototype include the following:

- insufficient flight range (only 50-70 meters), due to the specific design of the throwing device and throwing projectile,

- the use of gas as an energy source for launching a missile projectile, which slows down the process of a military-sports game due to the fact that it requires frequent refueling, and also affects the stability of the launching of a projectile from a throwing device, this is due to the fact that the gas used to start the product changes its characteristics at low ambient temperatures, in turn, decreases the range of the projectile;

- with frequent refueling of the gas tank, the filling valves wear out with time, which leads to the need for frequent replacement of these valves;

- technological complexity of the design and, consequently, the high cost of the throwing device;

- lack of safety of the throwing device, due to the fact that when using an initiating device of inertial type, an explosion of the throwing projectile may occur from a blow or "prick" the lower part of the throwing device, which leads to the subsequent initiation of pyromix inside the product;

- the presence of rifling on the barrel of the propelling device, which leads to an increase in the cost of its design.

The objective of the proposed technical solution is to create a throwing device of a simple design and a projectile of such a design that would allow to provide the necessary conditions for flying a projectile to distances up to 200 meters in order to obtain firework effects to simulate explosions during theatrical performances, to simulate the effect a shot from a grenade launcher, an imitation of the smoke screen effect, as well as for playing paintball, airsoft and other military sports games. At the same time, the projectile should have a high degree of safety for a person located near the explosion site of the projectile pyrotechnic projectile, and the projectile device does not require constant recharging, which would make holding military-sports games more comfortable and more affordable in financial terms.

The solution of the problem is achieved by a throwing device of a simple design and a throwing projectile, the design of which is designed so that the pyrotechnic mixture itself (pushing pyrotechnic mixture) emitting a large amount of energy during an explosion pushes the projectile with the main pyrotechnic mixture from the throwing device. Also, in order to reduce the loss of energy obtained from the ignition of the ejecting pyrotechnic mixture, the design of the propelling device and the projectile is designed to increase the degree of obturation of the pyrotechnic gases released. At the same time, the throwing device for simulating combat operations (hereinafter referred to as the device) consists of a body (the body of the throwing device) made of non-flammable material, the inner wall of which has the shape of a truncated cone designed to accommodate a missile projectile. The case of the device is fastened by means of a latch or bolted connection to the barrel of a grenade launcher, equipped, in turn, with a current source. The body of the device contains a hole for summing up the igniter, which, in turn, contacts are made from the current source, which ensures the heating of the igniter. As for the missile projectile to simulate the fighting (the projectile) - it contains the body (shell of the projectile), made of a traumatic material, an igniter with a pyrotechnic retarder-igniter, a protective film, under which the eject pyrotechnic mixture is located. The protective film is made of a traumatic flammable material and is designed to protect the ejecting pyrotechnic mixture from spilling and moisture ingress. The ignition of the buoyant pyrotechnic mixture leads to the formation of a sufficient amount of energy required to fly the projectile with the main pyrotechnic mixture out of the propelling device up to 200 meters (depending on the composition of the pyrotechnic mixture). The lower part of the body of the projectile, like the inner wall of the body of the projectile, has the shape of a truncated cone. Additionally, the body of the projectile may contain stiffening ribs for more reliable fixation and stabilization of the passage of the projectile device inside the barrel with a decrease in friction of the projectile in the projection device.

The essence of the claimed invention

Due to the fact that the inner wall of the projectile device and the lower part of the body of the projectile (4) are equally extended upwards (have the shape of a truncated cone), while the diameter of the projectile body is of such a size that it is tightly fixed by the inner side wall of the device body, EFFECT: increased obturation of pyrotechnic gases by ejecting pyrotechnic mixture (8). Increased obturation during firing prevents the reverse breakthrough of the pyrotechnic gases of the burning pyrotechnic mixture (8), which ensures the required initial velocity of the projectile for flight to the specified target and an increased range of the projectile. Due to the fact that the energy required for launching the projectile is generated by the ignited pyrotechnic mixture, and the main initiator of ignition is the igniter, which receives energy for heating from the current source, it is possible to achieve another technical result - the simplicity of the design of the throwing device. Additionally, the body of the projectile may contain stiffening ribs for more reliable fixation of the projectile in the projectile. Also, the body of the missile projectile may consist of one or more interconnected parts by gluing or snapping, or twisting.

Principle of operation.

Throwing device is located in the barrel grenade launcher. A grenade launcher is equipped with a current source, which, by connecting to an igniter (3), heats it after the user presses the grenade launcher. A heated igniter (3) burns through a protective film (7) located under the ejecting pyrotechnic mixture (8). Due to the fact that the protective film is made of flammable material, the combustion process immediately goes to the pyrotechnic mixture (8). During ignition, the pyrotechnic mixture (8) emits a large amount of energy, which is used in this technical solution for ejecting a missile projectile with the main as yet unburned pyrotechnic mixture (9). At this point, the pyrotechnic retarder ignitor (5) is ignited, which then ignites the main pyrotechnic mixture (9). Due to the presence of the pyrotechnic retarder (5), the main pyrotechnic mixture (9) ignites, explodes, destroying the body of the projectile after it travels a certain distance (up to 200 meters) or does not hit the barrier (depending on the type of the main pyrotechnic mixture).

The technical result of the claimed invention is expressed by the following features:

- long range (up to 200 meters);

- the use of an additional pyrotechnic mixture as an energy source, the explosion of which leads to the launch of a projectile, which does not slow down the process of conducting a military-sports game;

- the presence of stiffeners, which ensure the stability of the launching of the projectile from the throwing device;

- technological simplicity of the design of the throwing device and throwing projectile, which leads to a decrease in the cost of objects, in contrast to the closest analogue;

- high safety projectile.
