Compact Recoil Guide Device for Weapon Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weapon systems face challenges in reducing recoil forces and cradle mass, leading to increased bulk and effort on trunnions, as conventional guiding means require additional sleds and heavy recoiling masses.
Innovation Solution
A weapon system design featuring a recoiling mass with a breech sleeve connected to a cradle via hydraulic or pneumatic recoil brakes and a guiding mechanism comprising male bars and female rails, where the breech sleeve carries integral brake bodies and prismatic pads for guidance, eliminating the need for a dedicated sled and distributing mass effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional guiding means with sleds are used, then guidance of recoil movement is achieved, but the weapon system size increases and cradle mass increases
Solution Approach 1:
The guide rails are integrated directly into the breech sleeve structure, merging the guidance function with the existing recoiling mass component. This eliminates the need for separate sleds and reduces cradle mass while maintaining effective guidance of the recoil movement.
Solution Approach 2:
The guidance function is extracted from the cradle structure and transferred to the breech sleeve. By carrying the guide rails on the breech sleeve itself, the cradle is relieved of the need to support heavy guidance structures, reducing its mass.
2Force
If significant mass is given to the recoiling mass to reduce recoil forces, then recoil forces are reduced, but the weapon system becomes heavier
Solution Approach 1:
Hydraulic or pneumatic recoil brakes are used to control and reduce recoil forces. These devices provide controlled resistance during recoil movement, allowing the system to manage recoil forces without requiring excessive mass in the recoiling components.
3Force
If hydraulic or pneumatic recoil brakes are used to reduce recoil forces, then recoil forces are reduced, but device complexity increases
Solution Approach 1:
The recoil brakes are integrated with the breech sleeve structure, combining the braking function with an existing component. This integration approach reduces overall device complexity compared to having separate, standalone brake assemblies.

AI summary
The invention relates to a weapon system (1) comprising a recoiling mass (2) and a cradle (3), wherein the recoiling mass comprises a weapon barrel (2a) and a breech sleeve (2b) and moves in translation during firing relative to the cradle (3) and a guide means is provided for guiding this recoil movement of the recoiling mass (2). This weapon system is characterized in that the guide means comprises at least one bar (5) secured to the cradle (3) and extending rearwards from the weapon system, said bar (5) cooperating with at least one rail borne by the breech sleeve (2b). The breech sleeve (2b) is connected to the cradle (3) by two pairs (6a, 6b) of hydraulic or pneumatic recoil brakes (7), each rail being arranged between two brakes (7) of a same pair, the body of each brake (7) being secured to the cylinder head sleeve (2b).
