Magazine-Integrated Ammunition Sub-Modules for Launcher Load Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing launcher systems face challenges in increasing range without exceeding permissible loads on the launcher-ammunition interface, which is exacerbated by changes in the drive system and cartridges, and current solutions like stiffening the cartridge tube are undesirable as they require changes to the magazine system.
Innovation Solution
The integration of ammunition and magazine functions into sub-modules, where sub-modules are plugged together and locked, allowing for modular assembly and stabilization of ammunition during firing, while being compatible with existing systems.

1Length of moving object
If the drive system of the ammunition and its cartridges is changed to increase range, then the range is improved, but the loads on the interface of the launcher and ammunition rise above the permissible level
Solution Approach 1:
The system is divided into separate functional modules: the ammunition module (with drive system and cartridges) and the magazine module (with launcher interface). This segmentation allows the ammunition to be optimized for range without directly transmitting excessive loads to the launcher interface, as the magazine structure absorbs and distributes these loads.
Solution Approach 2:
The magazine acts as an intermediary between the launcher and the ammunition. It receives the ammunition with its modified drive system, absorbs the excessive loads generated during firing, and presents a compatible interface to the launcher. This mediator role allows range improvement in ammunition without compromising launcher integrity.
2Strength
If the cartridge tube is stiffened to counteract higher loads, then the load-bearing capacity is improved, but the magazining of the ammunition would have to be changed
Solution Approach 1:
The system separates the structural reinforcement function from the magazining function. The magazine structure, not the cartridge tube, provides the necessary load-bearing capacity. This allows the cartridge tube to remain simple while the magazine is designed to handle the loads from the modified ammunition drive system.
3Adaptability or versatility
If individual functions are transferred from ammunition to magazine, then the ammunition design flexibility is improved, but the overall system complexity increases
Solution Approach 1:
The magazine and ammunition are merged into an integrated module where the magazine structure serves dual purposes: it holds the ammunition and provides structural support for load management. This merging reduces overall system complexity compared to separate components while enabling functional transfer from ammunition to magazine.
Solution Approach 2:
The magazine is designed with multi-functionality: it serves as the holding structure for ammunition, the load-bearing component for interface compatibility, and the structural element that enables ammunition design flexibility. This universal design reduces the need for additional specialized components.

AI summary
It is proposed to connect the ammunition and the magazine (2) to each other not only in terms of design, but also in terms of function. The magazine (2) and ammunition are for all intents and purposes combined to form sub-modules (1), wherein a plurality of sub-modules (1.1-1.4) would then be comparable to the quantity of conventional ammunition in the launcher tube. Said sub-modules (1.1-1.4) are then preferably assembled and locked (as a module), which is comparable to a previously loaded magazine. The individual sub-module (1) contains, inter alia, rifling, by means of which, during firing, the ammunition/submunition is caused to rotate and is thereby stabilised.
