Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a practice artillery shell launcher comprising a large-caliber cylinder and a small-caliber cartridge mounted in a tube at the front of the cylinder.

Under the concept of "training shell" according to the invention, a shell is understood to mean a shell which is used for training purposes, both the shell itself and the device as a whole. The purpose of using this device is, in principle, to reduce the cost of live combat ammunition and to protect the weapon.

However, in doing so, efforts must be made to use training shells as much as possible with combat ammunition suitable for the situation, in order to enable simulations deployed under realistic conditions. This means that they must be formed in the same way.

(Prior Art) DE-O5 (German Publication No. 3048620) discloses a training weapon such as a cannon, artillery, etc. It is based on the respective adaptation of a weapon system within a large-caliber gun barrel. In this system, a small-caliber shell is fired from a tube inserted into the gun barrel.The advantage of a small-caliber shell is that it costs less and is more economical. However, it is usually impossible to realistically practice the loading procedures of weapon systems and the handling of shells in an original way.

To counter this shortcoming, the Menji Gazette recommends large-caliber combustible cartridges, known as flammable-cased artillery shells, instead of placing small-caliber shells in the chambers of small-caliber tubes. . In this way, the small-caliber cartridge, which is inserted into the center of the chamber of the training weapon already used in artillery, would be replaced by a large-caliber combustible cartridge with the same external shape as the cartridge.

[Problem that the invention seeks to solve]

The object of the present invention is to provide an artillery shell launcher in which battlefield scenarios are developed using training shells that are geometrically and gravimetrically similar to live combat ammunition, and in which the 'AN is primarily used. It is easily inserted into the cannon tube of a weapon such as a cannon, regardless of its caliber or weight, and, just as large-caliber artillery shells reach the battlefield, it is also ballistically adaptable and minimizes errors as much as possible. The goal is to improve the firing position so that it can reach its destination without projecting a bullet. .

[Means for solving problems]

In view of this, the present invention has devised a training artillery shell launcher consisting of a large-caliber cylinder and a small-caliber cartridge mounted in a tube in front of the cylinder and bombarded by a firing device within the large-caliber cylinder.

The firing device inside the large-caliber cylinder is equipped with an ignition charge that is attached to the breech plug side of the gun and is integrated with the ignition device, and a firing device that mechanically fires the ignition charge against the propellant loaded in the cartridge case. It consists of a firing pin mounted at intervals at the front.

Another advantageous feature of the device is that the igniter charge is bombarded by an electric igniter.

In the present invention, mechanical ignition of small caliber cartridges is made compatible with electrical ignition of any caliber associated with variable range. Here you can plug the weapon normally, just like when firing live ammunition. Electric igniters include an igniter that causes ignition by means of an impulse current;
The resulting heating rays begin to burn the charge. After the charge burns out, the internal pressure generated causes the cover placed over it to burst open. This gas pressure generated on land does not directly affect the firing of artillery shells, but
The device first impacts a firing pin that is spaced apart from the charge, and then the firing pin is activated, mechanically applying pressure to the propellant in the cartridge case and igniting the propellant. .

Instead of an electric ignition device for igniting the Moraron ignition charge, a physical ignition device can also be used.

In order to achieve the best kinematic conditions in the tube, in an advantageous embodiment of the device according to the invention, the firing pin is held at its working point by at least one safety device, which safety device is driven into position by combustion of the ignition charge. The mechanism is such that the firing pin is released when the gas pressure reaches . The safety devices used here include, for example, the use of a spring safety pin that receives fJiγ, which is inserted radially within the working range of the firing pin, and which is primarily used to connect the ignition charge to the firing pin. can be inserted into the hole in the firing pin associated with the pressure chamber between the firing pin and the firing pin. Then, when a predetermined gas pressure is reached, the safety vial is pushed aside and the firing pin is released and directed toward the cartridge.

Selectively or aiming at a cumulative effect, the present invention further devises the following. That is, the firing pin is fixed at this insertion point to at least one shearing element, which shears and releases the firing pin when the gas pressure built up by ignition of the charge reaches a predetermined value. be. Furthermore, in the present invention, the cartridge case can be inserted into a barrel that can be combined with the support or disassembled, and can be fixed by means of a fixing device.

Margins below [Effects of the Invention] The device according to the invention can be reused as many times as desired. Also, there is no need to disassemble and painstakingly reassemble the device each time a shot is fired. It may simply involve removing the bayonet barrel, which is connected to the support mainly by means of an intermediate switching reinforcing tube, after which a new cartridge is fitted into the bayonet barrel (reinforcing tube) by means of a suitable fixing device and this The barrel and support are fastened together using a screwdriver. The cartridge is now ready to fire again.

The boundary between the working range of the firing pin and its lower part is ensured in a simple way by dividing it by a ring flange fitted into the spacer tube surrounding the pressure chamber, so that the attached safety device The recoil pressure automatically inserts the hole in the firing pin, while the gtJ cutting pin can be attached to the corresponding hole through the support from the outside.

After replacing the ignition charge on the breech side of the gun, the entire weapon can be reinstalled and configured.

All of this setup is quick and easy.

Particularly in the device according to the invention, the cartridge case is most extensively matched to the original cartridge used in practice, also from the point of view of geometry, gravidynamics and ballistics. The small caliber cartridge is also suitable for use in armored tanks, for example, and can perform the full function of electrically igniting the tank's cannon and allowing it to be fired from the barrel.

Instead of the above-mentioned igniter charge, the small caliber cartridge can be directly impacted by an electric propellant igniter connected, for example, by a steel bar or conductor to an electric powder igniter on the breech side of the gun. Can be done.

〔Example〕

The device of the present invention will be explained in detail as follows based on the drawings.

The device shown in the drawings is useful for training use of cartridges in the chambers of tank tower guns.

Drawing number 10 shows the tube of the tower gun. The breech plug part inside this gun tube is sealed with a bottom cover 12, and an electric propellant igniter 14 is inserted into the center thereof. Electrical igniters are well known and include an igniter that is ignited by an electric current. These electric ignition devices come in a variety of configurations, which are distinguished by the method of ignition induction, such as ignition by melting a conducting wire. An ignition charge 16 is attached to the front of the electric ignition bag W-14, and the charge is sealed at its upper front end by a partition plate 18 (FIG. 1).

The ignition charge 16 is mounted inside a spacer tube 20 which is inserted into a cylinder 22 coaxial with the tower gun 10. In particular, as is clear from FIG. 2, the spacer tube 20 is formed with a step 24 on the outside at its front free end, and above the step is coaxial with the spacer tube 20. A support body 26 attached to is placed thereon.

The support body 26 is the back side of the ◇;;; (Fig. 1)
is adjacent to the tower cannon 10, but as it goes toward the front end, it tapers more sharply than the angle at which the fat pipe 10 gradually tapers forward. Therefore, a space 28 is formed between the support and the fat tube, and the support 26 is shaped like a truncated circle 11C with a firing pin through hole 30 in the center.

In particular, as can be seen in FIG. 2, the spacing tube 20 extends only partially into the support 26. Interval tube 2
The coronal plane of the 0 is the firing pin 3, which is essentially in the shape of a cylinder.
It is used to carry 2. From the lower end of the firing pin an axle 34 passes through the firing pin and forces outwardly a radially extending bore 36.

At the safety pin insertion point shown in Figure 2,
Coaxially with the hole 36, a hole 38 passes through the support 26, into which a safety bottle 4 is loaded which is impacted by a spring 40.
2 is attached.

The holes 36 and 38 as well as the safety pin 42
is configured to be forced into the bore 36 in the firing pin 32 by a spring 40 at its insertion point.

Spaced apart from hole 3G, a sack-shaped hole 44 passes into firing pin 32 from the outside. In order to extend this hole 44, a passage hole 46 is extended through the support 26, which includes a first portion 46a colinear with the hole 44 and an enlarged diameter portion outside thereof. There is a second portion 46b.

A shear pin 48 is inserted into the holes 44 and 46a, which is placed from the outside by a fixing nail in the hole 46b. The upper part of the through hole 46 is normally sealed with a firing pin 32 at the exit point of the gas.
A gas handling hole 4 that penetrates through and escapes to the outside space 28.
9 is passing.

A cylindrical protrusion 50 is attached to the upper coronal surface of the ±F needle 32, and its outer diameter is larger than the inner diameter of a through hole 52 installed coaxially with the cylindrical shape 50 in the upper part of the support body 26. is also slightly smaller.

The support body 26 is formed of a ring-shaped layer 54 surrounding the upper end portion, and a coil screw 5 is installed inside this ring-shaped layer 54.
It has a 6 on it. On the outside of the cylindrical reinforcing tube 58 there is also a coil screw 60 which matches this thread, so that the reinforcing tube can be fixed together with the support by means of a screwdriver. The reinforcing tube 58 has a reaction spring 6 which receives a fixing ring 64 at the end opposite to the support 26 across the reinforcing tube 58.
There are two retaining rings, which secure a small-caliber cartridge 68 and its propellant charge 76 via an annular tip 66.

Attached to the forward end of the cartridge is a reinforcing tube 58 with a recoil spring 70 on the outside, the spring having a coil thread on the outside that mates with the coil threading on the inside of the bayonet barrel 72 so that the reinforcing tube 58 and gun rjr72
is fixed with a screwdriver.

The relay portion from the reinforcing tube 58 to the insertion gun barrel 72 is formed by the tapered shoulder portion of the cartridge barrel.

Further, as can be seen from FIG. 1, the outer diameter of the reinforcing pipe 58 is somewhat smaller than the inner diameter of the tower fat pipe 10. This is because the space portion 28 extends to the front gun r[72, and the end of the space portion facing the reinforcing tube 58 is in contact with the fat pipe 10.

The operation of the device according to the invention is as follows.

After the propellant electric igniter 14 ignites and the igniter charge 16 is completely burned, the charge partition plate 18 is forced out by the internal pressure of the generated gas. At this time, the firing pin advances due to the pressure built up in the spacing tube 20, and the safety pin 42 is pushed into the pressure spring 40.
It comes off due to contraction. The shear pins 48 are also sheared once a certain pressure is achieved. The firing pin 32 moves quickly with the necessary kinetic energy due to the generated pressure until it reaches the mechanical propellant igniter 76 of the small caliber cartridge 68, and at the same time the ammunition is fired, the forward movement of the gamma needle 32 causes
A gas vent hole 49 is installed in the empty part, and gun smoke passes through this hole into the space 28 between the support 26 and the tower gun 10 or between the reinforcing pipe 58 and the tower gun 10. Enter and disappear.

The manner in which the device can be reused has already been described above.

Using the device according to the invention, it is also possible to fire small 1" diameter cartridges which are attached to the tip of a "large caliber cartridge". Therefore, the cartridge case of this device is the most comprehensively compatible from the point of view of geometry and gravidynamics to the original cartridge case of relatively large caliber. For example, in an armored tank, cartridge handling, including firing, can be trained in the same way as when using live combat ammunition.

The device according to the invention also provides, by adapting the igniter charge,
Any distance from the propellant igniter of the large caliber cartridge to the propellant igniter of the ammunition in the barrel can be relayed.

The ignition of the cartridge is therefore independent of its distance from the electric ignition at the base of the cannon.
