DE202013004908U1 - Transition profile segments for runs - Google Patents

Abstract

Transient profile segments for short or long self-loading or repeating weapons where bullet guidance is achieved through the barrel. characterized in that the transition is ensured in the bullet guide in the run by interchangeable segments.

Description

1st area:

The system belongs to the weapon technology

2. State of the art:

In conventional systems, the transition of the projectiles in the run, by a cone (cone) in the running profile is achieved.

3. Findings:

• 1. ( Caliber / 5/95 / S. 17 )
• 2. ( Caliber / 6/91 / S. 22 )
• 3. ( DWJ / 8/84 / S. 982-986 )
• 4. ( DWJ / 5/96 / S. 716 )
• 5. (ball swirl system for runs German utility model no. 297 06 936.5 )

4th problem:

The shortcoming of the current systems is that the running profile of the transition is more or less worn out by constant use and that the erosion at high gas pressures causes a very strong wear of the transition in the running profile.

5th invention:

This deficiency is eliminated by the fact that the transition cone of the projectiles is no longer achieved by conventional profiles (field train or polygon), but movable profile segments, which are embedded in the barrel, take over the transition of the projectiles in the tread.

6. Function of the system:

By incorporating profile segments in a run with non-profiled transition, which take over the function of the transition cone by their grandeur, the projectiles are provided with the necessary swirl profile.

7. Advantages:

This makes it possible to achieve a high number of shots, even with high gas pressure, without the barrel being subject to significant wear in the bullet guide profile of the transition.

8. Presentation of the invention:

An embodiment of the invention is illustrated in the drawing and will be described in more detail below:
