Weapon Barrel Stabilization via Dynamic Inertia Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-caliber weapons experience regulation errors and stabilization issues due to changes in mechanical inertia and imbalance caused by the return travel of the barrel, leading to inaccuracies in alignment and stabilization.
Innovation Solution
Measuring the positioning of the weapon barrel relative to the support using sensors and feeding the data to a control device to adjust the barrel's angle of incidence through a predetermined functional relationship, allowing for advance control and regulation to minimize deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the barrel is allowed to move relative to the weapon support during return travel, then the mechanical system can accommodate firing recoil, but changes in mechanical inertia and imbalance occur that degrade stabilization quality and alignment accuracy
Solution Approach 1:
The control device calculates and applies compensation values in advance based on the measured return travel position of the barrel. By determining the required compensation for imbalance and inertia changes before they fully manifest, the system proactively counteracts the effects of barrel movement, maintaining stabilization quality throughout the return travel cycle
Solution Approach 2:
The system continuously measures the actual return travel position of the barrel using position sensors and feeds this information back to the control device. This real-time feedback enables the control device to dynamically adjust compensation values for imbalance and inertia changes, ensuring accurate stabilization despite ongoing barrel movement
2Measurement precision
If alignment regulators and stabilization regulators are used to counteract vertical pivoting movements, then barrel alignment can be maintained, but regulation errors occur due to dynamic changes in inertia and imbalance
Solution Approach 1:
The control device calculates compensation values for imbalance and inertia changes based on the measured return travel position before these changes fully affect the alignment regulators. This preliminary compensation reduces the burden on alignment regulators and minimizes regulation errors by pre-counteracting the dynamic effects
Solution Approach 2:
The control device acts as an intermediary between the barrel position sensors and the alignment/stabilization regulators. It processes the raw position data, calculates appropriate compensation values for imbalance and inertia changes, and delivers corrected control signals to the regulators, thereby improving their accuracy and reducing regulation errors

AI summary
The method serves for adjusting a positioning of a longitudinal axis of a weapon barrel. An adjusting angle of the weapon barrel is changeable by at least one adjusting element. The weapon barrel is arranged so as to be movable relative to a weapon support in the direction of the longitudinal axis. A positioning of the weapon barrel relative to the weapon support is determined by measurement technology. The measurement values obtained as a result are supplied to a control device. The control device acts on the adjusting element in accordance with a predetermined functional relationship between the obtained measurement values and an input value for the adjusting element. The device for firing shell s is constructed for use of the respective method.
