Gas Piston Mounting on Weapon Barrel for Spring Load Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited space in the weapon housing restricts the maximum length of closing springs, preventing them from adequately absorbing increased load changes, which can lead to inefficiencies in the weapon's operation.
Innovation Solution
The gas piston is removed from the weapon housing and mounted on or in the gun barrel, allowing for the integration of longer recoil springs and recoil spring sleeves, with the gas piston connected to the weapon barrel via a gas channel, enabling direct action on the recoil spring device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the gas piston is mounted in the common housing with the closing springs, then the structure is compact and integrated, but the maximum length of the closing springs is restricted and they cannot adequately absorb increased load changes
Solution Approach 1:
The patent divides the weapon system into separate functional modules: the gas piston system is mounted on the gun barrel while the closing spring device is integrated into the weapon housing. This segmentation allows each component to be optimized independently - the gas piston for compact integration and the closing springs for maximum length and load absorption capacity.
Solution Approach 2:
The gas piston is relocated from the internal housing space to the external gun barrel surface, utilizing a different spatial dimension. This dimensional change frees up the entire housing volume for the closing spring device, enabling longer springs that can adequately absorb increased load changes.
2Strength
If longer recoil springs are used to absorb increased load changes, then the load absorption capacity increases, but the available space in the weapon housing is insufficient to accommodate them
Solution Approach 1:
The gas piston is extracted from the weapon housing and mounted on the gun barrel instead. This extraction creates sufficient space within the housing to accommodate longer recoil springs and recoil spring sleeves that can properly absorb increased load changes during operation.
3Volume of stationary object
If the gas piston is removed from the weapon housing, then longer recoil springs can be integrated into the housing, but the gas piston requires a separate mounting location on the gun barrel
Solution Approach 1:
The gas piston is merged with the gun barrel structure by mounting it directly on the barrel surface. This combination eliminates the need for separate internal housing space for the gas piston while maintaining its functional integration with the weapon system, allowing the housing to be fully utilized for the closing spring device.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables the absorption of increased load changes by utilizing longer and stronger recoil springs, enhancing the weapon's operational efficiency and reliability.
Implementation Method 1
In the case of self-propelled weapon systems, such as a gas pressure loader, the reloading and movement of a breech is carried out by the pressure of the powder gases.
Implementation Method 2
The gas piston is connected to the weapon barrel via this gas channel(s).

AI summary
A weapon system (10) is proposed, comprising a weapon barrel (2) and a breech mechanism (7), which is guided in a weapon housing (3) and is moved by way of at least one gas piston (4) and a return spring device (13), which structurally adjoins and interacts with the gas piston (4). In this system there are gas channels (14) between the weapon barrel (2) and the gas piston (4). To achieve the effect that a load change can be absorbed better by the return springs (5), it is provided that the gas piston (4) is now mounted on or in the weapon barrel (2) and only the return spring device (13) is integrated in the weapon housing (1).
