Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current artillery munitions face performance restrictions when switching between different ranges, requiring larger storage allocations and more frequent inspections due to lower payload volume and quantity, leading to inefficiencies and aging issues.
Innovation Solution
A munitions construction kit concept using a uniform projectile casing with interchangeable components, such as projectile bases and payloads, allows for customer-specific configuration of artillery projectiles, optimizing payload or range based on selection, enabling efficient storage and assembly of various munition types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a uniform projectile casing is used for various ranges, then storage outlay is reduced and logistics are simplified, but payload volume and quantity are reduced for longer range projectiles
Solution Approach 1:
The projectile is divided into separable components: a uniform projectile casing and interchangeable projectile bases. This segmentation allows the same casing to be used across different range variants while maintaining optimized payload volumes for each specific configuration.
Solution Approach 2:
The projectile casing is designed as a universal component that serves multiple range configurations (30 km, 40 km). By making the casing multi-functional and pairing it with interchangeable bases, the system reduces the number of unique casing designs needed, thereby reducing storage requirements while accommodating different payload volumes through base variations.
2Length of moving object
If payload is reduced for 40 km range optimization, then range performance is improved, but payload volume and quantity are reduced
Solution Approach 1:
Different projectile bases are designed with specific local characteristics: the 40 km base includes a gas generator for base bleed to extend range, while the 30 km base is optimized for payload capacity. This local differentiation in base design allows each variant to be optimized for its specific range while sharing the common casing structure.
Solution Approach 2:
The projectile base design parameters are changed to achieve different ranges: the 40 km base incorporates a gas generator that alters the pressure and flow parameters during flight to extend range, while the 30 km base uses different parameters optimized for payload delivery. These parameter changes in the base component enable range optimization without requiring different casings.
3Adaptability or versatility
If larger munition allocations are stored for selection between ranges, then range flexibility is improved, but storage needs increase and munitions age
Solution Approach 1:
The munition system is segmented into a common reusable casing and interchangeable range-specific bases. This allows the bulk of the munition (the casing) to be stored once and reused across different range configurations, reducing the need to store complete assembled munitions for each range variant.
Solution Approach 2:
The system enables dynamic configuration where bases can be exchanged based on mission requirements. Instead of storing static pre-assembled munitions for each range, the dynamic assembly of casing plus selected base provides range flexibility on demand, reducing overall storage needs and preventing munition aging.

AI summary
A uniform projectile casing which is utilized for projectiles with different ranges. A projectile of relatively short range can in this case be optimized with regard to payload, whereas a projectile with the relatively long range is subjected to a range optimization, with a reduction in payload. The payload of a projectile of relatively long range is generally lower in relation to a projectile with relatively short range. The artillery projectiles have a projectile casing of equal size for the projectiles of different range. To create an artillery projectile, for example 155 mm, a uniform payload-optimized 30 km projectile casing) is used, from which 40 km projectiles can be generated (produced, assembled) by means of a reduction in payload. The range is selected and defined by mutually different projectile bases. The artillery projectile has multiple modular parts which are assembled in order to create the artillery projectile.
