Adaptive Acceleration Limiting for Gun Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for stabilizing artillery movements during firing sequences are expensive and fail to account for hit behavior, leading to increased scatter due to incorrect measurement of carrier-induced movements by sensitive measuring systems like gyroscopes, which are influenced by recoil forces.
Innovation Solution
A history-based, adaptive acceleration limitation system that continuously stores and updates measurement data during non-firing periods to suppress disturbances from recoil forces during firing, ensuring accurate gun control by limiting measurement data to the maximum recorded acceleration values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sensitive measuring systems like gyroscopes are used to stabilize the bore axis, then stabilization performance is improved, but measurement precision deteriorates due to erroneous detection of carrier-induced movements during firing
Solution Approach 1:
The patent extracts and separates the harmful measurement data caused by recoil forces from the useful measurement data representing actual carrier movements. By identifying and excluding the erroneous measurements during firing sequences, the system maintains stabilization performance while improving measurement precision for non-firing periods.
Solution Approach 2:
The system performs preliminary measurement of carrier-induced movements during non-firing periods to establish baseline acceleration values. These pre-measured values are stored and used to identify and filter out erroneous measurements during subsequent firing sequences, preventing recoil forces from contaminating the stabilization data.
2Stability of the object's composition
If measurement data is continuously stored and used for acceleration limiting, then stabilization performance is improved, but device complexity increases due to history-based adaptive acceleration limiting system
Solution Approach 1:
The patent implements a dynamic acceleration limiting system that adapts to changing operational conditions. The system continuously adjusts the acceleration limits based on the current firing state and historical measurement data, allowing the same hardware to handle both stationary and moving platform scenarios without requiring complex manual reconfiguration.
Solution Approach 2:
The measurement system is designed to serve multiple functions: it measures carrier-induced movements during non-firing periods, stores historical data for acceleration limiting, and filters erroneous measurements during firing. This multi-functionality reduces the need for separate specialized systems, thereby managing complexity while improving stabilization performance.
3Measurement precision
If adaptive acceleration limit is applied during firing sequences, then measurement precision is improved by suppressing recoil disturbances, but productivity decreases due to continuous data processing and history maintenance
Solution Approach 1:
The system implements periodic processing of measurement data, where data is continuously collected during non-firing periods but processed and used for acceleration limiting only when needed during firing sequences. This periodic activation of the full processing algorithm reduces computational load during idle periods while maintaining high measurement precision during critical firing phases.

AI summary
The invention relates to an acceleration limiting means for gun-carrier-induced movements acting on a weapon (1) which is installed on a carrier (3) moving with an object. In order to prevent the measurement data of the carrier movement which are distorted by the recoil forces of the weapon during the firing sequence from being included in the gun control of the weapon (1), the movement of the carrier (3) is measured during the time in which the weapon (1) is not fired. The continuously measured data are stored separately or in parallel with their use in the gun control system and a history of the maximum occurring accelerations of the carrier (3) is determined. During a firing sequence of the weapon (1), the maximum values of the history are used for the acceleration limitation of the measurement data distorted by the recoil forces. The measurement data limited in this way are then taken into account in the gun control.
