Segmented Artillery Charge Shell for Long-Length Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artillery charges face stability issues due to the collision of modular shells at contact points, leading to a loss of propelling charge capacity and limited range, especially in longer shells.
Innovation Solution
A shell design incorporating a housing with a stabilizing element, such as a stabilizing disk, that separates the cavity into subcavities, allowing for improved mechanical stability and efficient use of propelling charge, especially in shells over 1100 mm long.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If modular shells are used to increase propelling charge quantity, then the range of the projectile is increased, but the cover and floor collide at the contact points leading to a loss of maximum available propelling charge capacity
Solution Approach 1:
The shell is divided into multiple modular sections that can be connected end-to-end. Each section has its own floor and cover, eliminating the need for intermediate contact points between sections. This segmentation allows the shell to achieve the required length for increased range while maintaining full propelling charge capacity in each section without collision losses.
Solution Approach 2:
The invention transitions from a single-section shell design to a multi-section modular arrangement, adding the dimension of serial connection along the longitudinal axis. This dimensional change allows the shell to achieve greater length without the traditional cross-sectional collision problems that limit propelling charge capacity in single-section designs.
2Length of moving object
If the shell length is increased to increase range, then the propelling charge quantity is increased, but the stability of the shell deteriorates
Solution Approach 1:
The shell is divided into multiple modular sections with individual floors and covers. This segmentation creates multiple rigid compartments that maintain structural stability even as the overall shell length increases. Each section acts as an independent stability unit, preventing the shell from becoming unstable due to excessive length.
3Length of moving object
If the shell length is increased beyond 1100 mm, then the range is increased, but the stability becomes insufficient without additional stabilizing elements
Solution Approach 1:
The shell is divided into multiple modular sections with individual floors and covers. This segmentation creates multiple rigid compartments that maintain structural stability even as the overall shell length increases. Each section acts as an independent stability unit, preventing the shell from becoming unstable due to excessive length.

Implementation Method 1
The propelling charge serves to cause acceleration of the artillery projectile by means of an exothermic reaction
Implementation Method 2
an igniter tube (70) extending in the longitudinal direction (L), wherein a flame front ignites the propelling charge (90) in the cavity (12)
