Description

The invention relates to weapons technology, propelling explosive devices and can be used to launch shells, bullets, capsules.

The current level of technology allows the use of spring throwing devices, high-speed pneumatic, powder and explosive (using chemical explosives) throwing devices.

A known method of throwing a projectile with a high initial speed using compressed gas [1].

This method provides the operation of an air rifle with small bullets for sports shooting.

There is a free-piston internal combustion engine capable of operating during detonation combustion of a fuel mixture (air and liquid or gaseous fuel) [2].

With some refinement, it can be used as an energy source of gaseous combustion products and detonation waves in a launcher.

Known explosive device for high-speed throwing (prototype) [3].

This device uses an explosive charge, the initiation of which produces a working gas. The disadvantages of the prototype include the complexity of the preparatory processes for repeated cycles, the need to follow certain safety measures.

The problem to which the invention is directed, is to create a launcher that runs on liquid or gaseous fuel in conditions of detonation of the fuel mixture. At the same time, it must act with a given cycle.

This is achieved by the fact that the system of free-piston internal combustion engines (hereinafter - SPD), quantitatively determined depending on the required power of the launcher, is equipped with a gun carriage and mounted on a vehicle. SPD cylinders are united by one head with windows, through which the energy of the explosion of the fuel mixture enters the barrel, which is set depending on the caliber of the ammunition, and performs the work of pushing out a projectile or bullet at high speed. When replacing the barrel with a smaller caliber and excess power, you can turn off the required number of SPD cylinders by blocking workflow services on them.

LDS workflow support systems operate from the internal combustion engine of a vehicle through pipelines. The non-expendable high-pressure system is provided by a cylinder and pipelines. The weapon power system with bullets or shells is common for such devices.

Figure 1 shows a General view of the launcher. The following position designations are accepted: barrel 1, head 2, SPD 3, high pressure system pipeline 4, carriages 5, lubrication system pipeline 6, cooling system pipeline 7, fuel system pipeline 8.

Figure 2 shows a sectional view of the main components of the assembly.

The following position designations are accepted: barrel 1, projectile (bullet) 9, head 2, window 10, cooling system pipe 7, piston 11, power accumulator 12, fuel system pipe 8.

The proposed launcher works as follows. Using a weapon power system, a projectile (bullet, capsule) 9 enters the barrel 1 (Figure 2). Depending on the type of fuel in the tank of the vehicle, the corresponding fuel mixture is prepared and through the pipelines of the fuel system 8 enters the head 2, a single one for each cylinder (Figure 2). From the cylinder, compressed gas or air of the corresponding pressure through the pipelines of the high pressure system 4 (FIG. 1) compresses the fuel mixture entering the head 2 until it is detonated by means of an energy accumulator 12 and a piston 11 kinematically connected with it (FIG. 2). The explosion energy of each SPD through the windows 10 in the head goes into the barrel 1 and does the work of high-speed ejection of the projectile or bullet 9 from the barrel 1 (Figure 2). The piston system 11 - the energy accumulator 12 smoothes the reaction force from the shot (Figure 2), returns air or gas to the high-pressure tank. The lubrication system 6 reduces friction between the piston 11 and the energy accumulator 12 (Figure 1, Figure 2) and the cylinder, partially removes heat, providing a long service life of the mechanism. Similarly, the cooling system 7 removes heat from the head 2 (Figure 1, Figure 2) and the cylinder.

Repeated shots from the launcher are accompanied by the above preparatory processes.

The disadvantage in the proposed launcher is the relative complexity of the mechanism. This is compensated by the possibility of using conventional ICE technologies, installation of finished parts and assemblies.

The advantages include the ability to change the power of the installation by the number of connected SPDs, to replace barrels of various lengths with the caliber of a projectile or bullet. The adjustable compression ratio allows the use of gasoline of all grades, gas, diesel fuel, kerosene as fuel. Mobility launcher is the ability to install it on any vehicle with an internal combustion engine. Reducing the cost of ammunition (there is no need for gunpowder, shells). More secure storage and transportation of ammunition.
