Abstract

The weapon has a housing (12), where the weapon (10) is linearly movably guided in an axial longitudinal direction. The weapon moves back unbraked in the housing in a return motion path that is limited and defined by return motion damper (32). Shoes are provided in the weapon in mutually axially spaced relationship, where the shoes are linearly movably guided in guides of the housing.

Description

The invention relates to an automatic firing weapon according to the preamble of claim 1.

It is known that an automatic firing weapon acts by recoil forces on the weapon game and the vibration of the barrel and thus has a relatively large Treffbildstreuung. In addition, automatic weapons tend to buckle against the restraining forces (lashings), i. The weapon rises from shot to shot. The influence of the gradual Aufbäumens is trying to counteract by automatic or shooter-related Schusszahlbegrenzer. However, this is only possible to a limited extent. Therefore, long bursts, also due to the impact factor of the shooter, are common. Long bursts of fire are usually a waste of ammunition.

In view of these circumstances, the invention has for its object to provide an automatic firing weapon of the type mentioned with improved hit probability, so that an ammunition saving can be realized.

This object is achieved by the features of claim 1. Preferred embodiments or further developments of the automatic firing weapon according to the invention are characterized in the subclaims.

With the automatic firing weapon according to the invention, in particular for caseless ammunition, it is possible - due to the possible high firing frequency - to fire recoilless bursts of fire up to, for example, 10 shots. The firing frequency can be z. B. 2000 to 3000 rounds per minute.

During firing the weapon according to the invention runs in a housing in its axial longitudinal direction linearly guided unrestrained, so that during firing recoil forces are avoided on housing and shooter. After delivery of the last shot of the respective burst of fire, the weapon runs against a return damper. In the case of the weapon intake, i. the housing, initially recoilless burst, are the effects on weapon scattering behavior, i. on the Treffbildstreuung, much smaller than a known automatic firing weapon.

Due to the shot burst limited bursts, the return damper, i. the weapon return damping at the end of a weft yarn advantageously be designed to be significantly longer and softer. This has an advantageous effect on the weapons suspension. Less hard blows allow for a smaller, lighter weapon suspension.

The soft, longer Waffendämpfungsweg can be coped with by the relatively long Waffenrücklaufweg advantageously time without problems.

A shooter using the automatic firing weapon according to the invention can - due to a shot number - i. Firestop Limiter - Deliver a new targeted burst every 1 to 1.5 seconds. The effective firing frequency of a weapon system according to the invention is then e.g. on the order of 150 to 500 rounds per minute. This advantageously results in a clear ammunition saving, in particular for caseless ammunition, in comparison with a conventional automatic firing weapon.

Further details, features and advantages will become apparent from the following description of an embodiment shown in the drawing of the automatic shooting weapon according to the invention, in particular for caseless ammunition.

Figures 1 and 2 show an embodiment of the automatic firing weapon 10 according to the invention, wherein the weapon 10 is guided linearly movable in a housing 12 in the axial longitudinal direction.

The reference numeral 14, a gun barrel of the weapon 10 is designated.

On the weapon 10 axially spaced sliding blocks 16, 18 and 20 are provided. The shoe 16 is z. B. between the weapon 10 and the barrel 14 is provided. The shoes 18 and 20 are provided axially spaced from the shoe 16 to ensure optimum guiding properties.

The shoes 16 and 18 are in guides 22 and the shoe 20 is provided in a guide 24 linearly movable. The guide 24 is formed by a guide groove 28 formed in the housing 12. The guides 22 are formed by slide rails 30.

The shoe 16 between the weapon 10 and the gun barrel 14 may be similar to the skids 18 and 20 may be formed and guided in respective guides 22 and 24.

During a burst of fire, the weapon 10 with the barrel 14 in the housing 12 unrestrained runs a return path x, which is determined by a return damper 32 and limited. The return damper 32 has a brake element 34 and a spring element 36. The brake member 34 is provided on the guides 22 and 24 rearwardly adjacent. The spring element 36 is arranged in a blind hole recess 38 of the housing 12.

On the weapon housing 12, a return-dependent Schusszahlbegrenzer 40 is additionally provided.

The weapon 10 has an ammunition feeder 42, through which the number of shots of a burst of fire is adjustable.

In FIG. 1, x1 represents the return path of a first shot, x2 the return path of a second shot following the first shot, and x3 the return path of the weapon 10 of a third following the second shot Shot called. The recoilless weapon return path x is the sum of x1 + x2 + x3.

mit i = 1 bis n.The above statements apply to a three-shot firing burst. More generally, the recoilless weapon return path $$\mathrm{x}={\displaystyle \Sigma \mathrm{x}\mathrm{i}}$$

with i = 1 to n.
