DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gun,
The ammunition unit and the launching device with aiming device
Made of fiber reinforced plastic, on both sides
The wall thickness of the open barrel in the center area
Large enough to withstand high ignition pressures
(High-pressure barrel), ignited around the center area of the barrel
A ring is attached and the gun barrel has a firing device
Bead-shaped ridges are provided as support surfaces for
About the things of that format.

[0002]

2. Description of the Prior Art Ranges of this type up to 600 m.
Portable anti-tank gun made of lightweight construction material with
An artillery having a caliber of 120 mm is known, for example, under the name DARD120.

[0003] In the central area of the barrel where the ignition takes place, about 1
Pressures of over 2,000 bar can occur. Under such loads, the fiber-reinforced plastic barrel expands relatively large, especially when the axis of the sighting scope fixed to the launcher is tilted with respect to the axis of the barrel or the trajectory of the bullet. I will.

[0004]

SUMMARY OF THE INVENTION The object of the invention is to improve a gun of the type mentioned at the outset so that the extension movement of the high-pressure gun barrel is reduced.
As little as possible to the launcher, and of course
Fire that keeps the overall weight of the cannon as low as possible
Is to provide guns .

[0005]

SUMMARY OF THE INVENTION In order to solve this problem, according to the structure of the present invention, a gun barrel is provided between a gun barrel and a firing device.
A tightly coupled adapter tube is provided, provided that
The adapter barrel is only barreled through the bead-shaped ridge
And the bead-shaped ridge is connected to the center of the gun barrel.
Outside the range, on the barrel, at least
A gap is provided between the adapter barrel and the barrel
It was as.

[0006]

According to the present invention, since the adapter cylinder is provided between the barrel made of fiber-reinforced plastic and the launching device, a large extension that occurs in the central region of the barrel during the firing is provided in the launching device. Transmitted to the aiming device
Is achieved .

[0007] installed closest to the ignition ring,
The adapter tube is supported (preferably glued
The bead-shaped ridge is about 10 cm from the ignition ring.
Have been separated . In this position, the 1 millimeter or more
The ignition ring itself and its surroundings where movement may occur
The maximum radial extension of the gun barrel is 10%
Below.

The adapter tube, which is preferably made of metal, is mounted on the barrel concentrically from its support point to the ignition ring without hindrance. Two beaded ridges about 10 mm wide
It is advantageous if only the starting part is wound around the barrel . These bead-shaped ridges protrude from the outer diameter of the barrel by about 1 to 5 mm, so that the adapter cylinder can barely cover the barrel.
It is processed as follows . Bead-shaped ridges on the barrel
Advantageously, the adapter tube is glued to the part . The gap between the adapter barrel and the barrel is left empty,
Or it may be filled with plastic foam .

[0009] In a particularly advantageous refinement of the invention, the adapter tube which is fed to the ignition ring is provided on the ignition ring.
It can also be inserted under an overhanging edge . In this case, this location serves to increase the stability without a firm connection between the ignition ring and the adapter tube. When the middle area of the barrel is extended during a bombardment, the ignition ring is also significantly deformed, as described above. At this time, the ignition ring primarily expands radially, or adapter tube
The ignition ring will move its adapter
Does not transmit to cylinder . This makes the launching device torsionally rigid
No need to form or form more stable structure
In addition, the launching device is hardly bent, and
Position adjustment of the aiming scope fixed to the shooting device is also prevented
Can not be . Maintaining accurate alignment is also important because the firing device is used repeatedly.

The firing device does not necessarily have to concentrically surround and hold the barrel. It suffices for the launcher to grip the barrel from below on one side. Advantageously, four support points are provided on the adapter tube, in which case each of the two support points has the shape of a bead outside the adapter tube.
In the area of the ridge , i.e. where the adapter barrel is in direct contact with the barrel, in which case the distance between the launcher and the adapter barrel does not always remain constant
There are unlimited gaps . The support point is machined so that the launch device can be mounted coaxially to the barrel.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

[0012] A barrel 1 of approximately 1 m length with a liner 2 made of a lightweight construction material, that is to say mostly of glass fiber reinforced plastic or carbon fiber reinforced plastic.
Has an ignition ring 3 at substantially the center. In the region of the ignition ring 3, a pressure of up to 1400 bar occurs on the barrel 1 . The barrel 1 must be connectable to a launching device. In the configuration of the present invention, the barrel 1 is
Based on being combined with a launcher,
Even if stretching occurs, only slight movement of the launcher is generated
What is achieved is achieved . The launching device with aiming scope has to reach the height of the ignition ring 3 for technical and ergonomic reasons, but in the configuration of the invention the adapter tube 4 is fixed to the ignition ring 3 itself. Instead, it is inserted under the edge 5 provided on the ignition ring 3. The rim 5 enhances a stable fixation between the barrel 1 and the launching device, but prevents the expansion in the central area of the barrel 1 from being transmitted to the launching device. The gun barrel 1 is provided with at least two bead-shaped ridges 6 and 7, and these bead-shaped ridges are provided.
6 and 7 directly support the adapter tube 4, and
A support surface for supporting the launching device fixed to the barrel 4;
Work . The adapter tube 4 is particularly close to the ignition ring 3,
Together with the barrel 1, a gap 8 of about 1 mm is formed.

[0013] The fixed principle of the firing device in the adapter tube 4, has been performed traditional, direct of the launcher and the barrel
It can be carried out in the same way as in the case of a typical connection . A point-like transition has been found to be sufficient instead of an annular fixed form. In such a configuration, two support points 9 and 10 are provided on the adapter tube 4 at two places, respectively, and in this case, the support points 10 are located on the bead-shaped protrusions 7. The support points 9 and 10 are made of light metal,
cm. The four support points are the barrel axis
Line 11 is aligned with the axis of the sighting scope fixed to the launcher
Each barrel is individually post-machined so that it is aligned . Adapter tube 4 is made of light metal and is about 2 mm
And protects the gun barrel and gunner
It also provides another means of protection .
