Segmented Sabot Assembly for Consistent Multi-Projectile Shot Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current direct fire weapons are inadequate for neutralizing small, fast-moving targets like drones due to limited range, variable shot pattern, and low rate of fire, posing risks to personnel and assets.
Innovation Solution
A sabot assembly with a unique housing design that separates and releases projectiles after firing, maintaining projectile shape and velocity, ensuring accurate and consistent shot patterns at long ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional multi-projectile cartridges (shotshells, canister cartridges) are used, then multiple projectiles are fired simultaneously, but the projectiles deform under high pressure and velocity, reducing velocity, range, and accuracy
Solution Approach 1:
The cartridge is divided into separate compartments, each containing an individual projectile. This segmentation prevents projectiles from deforming under pressure while maintaining the multi-projectile capability, as each projectile is isolated in its own compartment during firing
Solution Approach 2:
Multiple projectiles are nested within individual compartments inside the cartridge housing. This nested structure allows multiple projectiles to be contained without direct contact between them, preventing deformation while maintaining compact cartridge design
2Quantity of substance
If traditional multi-projectile cartridges are used, then multiple projectiles are fired, but the shot pattern is variable and inconsistent at long ranges
Solution Approach 1:
The cartridge is segmented into separate compartments with individual projectiles positioned in fixed, predetermined locations. This ensures consistent spacing and distribution of projectiles, creating a reliable and repeatable shot pattern at long ranges
Solution Approach 2:
Each compartment is designed with specific local characteristics to control projectile placement and orientation. This local quality control ensures that each projectile maintains its intended trajectory and positioning, contributing to overall shot pattern consistency
3Quantity of substance
If shotgun firearms are used, then multiple projectiles are fired simultaneously, but the rate of fire is low and range is limited
Solution Approach 1:
The cartridge design is universal and can be adapted to various firearm calibers and types (rifles, shotguns, cannons). This multi-functionality allows the system to achieve high projectile output while maintaining compatibility with different firearms capable of high rates of fire
Solution Approach 2:
The cartridge parameters (caliber, projectile count, compartment configuration) can be changed to optimize for different firearms and engagement scenarios. This allows the system to achieve both high projectile quantity and high rate of fire by matching cartridge parameters to the specific firearm's capabilities

AI summary
A sabot assembly includes a housing defining an interior space and a plurality of projectiles and received in the interior space. The interior space is at least partially defined by a plurality of concavities, each of which is configured to receive a respective projectile. The housing is configured to separate and fall away once the sabot assembly is fired through a gun barrel, thereby releasing the projectiles from the interior space toward a target prior to impact of the sabot assembly with the target.
