Horizontal Dispersion Projectile Payload Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spin-stabilized projectiles with circular dispersion patterns are inefficient for surface targets due to high sub-projectile waste and increased collateral damage, as they are heavy and designed for air targets, leading to a low hit rate and increased risk of unintended damage.
Innovation Solution
A payload container design featuring sub-projectiles arranged in a linear or layered configuration within a cylindrical container, with each container displaced at a predetermined angle to achieve a horizontal dispersion pattern upon release, allowing for increased penetration and reduced collateral damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sub-projectiles are arranged in a circular dispersion pattern, then the projectile can engage air targets effectively, but the hit rate against surface targets decreases and collateral damage increases
Solution Approach 1:
The payload container is designed to rotate during flight, dynamically changing the dispersion pattern from circular to horizontal. This dynamic adjustment allows the same projectile to optimize its dispersion pattern based on the target type, resolving the contradiction between air target engagement and surface target hit rate.
Solution Approach 2:
The invention changes the dispersion pattern parameter from a fixed circular pattern to a variable pattern that can become horizontal through rotation. By changing the orientation parameter of the payload container during flight, the system adapts to different target types, improving hit rate against surface targets while maintaining air target capability.
2Quantity of substance
If the number of sub-projectiles is increased to improve hit rate, then the quantity of payloads increases, but the projectile weight increases and may exceed carrying capacity
Solution Approach 1:
The payload is segmented into multiple small sub-projectiles arranged in a compact linear configuration within the container. This segmentation allows maximum number of sub-projectiles to be packed into the available volume without excessively increasing overall projectile weight, as the linear arrangement optimizes space utilization.
Solution Approach 2:
The sub-projectiles are arranged in a linear configuration along the longitudinal axis of the container rather than distributing them in three-dimensional space. This one-dimensional arrangement maximizes the number of sub-projectiles within the constrained volume and weight limits of the projectile.
3Area of stationary object
If sub-projectiles are released in a circular pattern, then the dispersion area is maximized, but the concentration of sub-projectiles on surface targets decreases
Solution Approach 1:
The payload container rotates during flight to dynamically transform the dispersion pattern from a wide circular area to a concentrated horizontal line. This dynamic transformation concentrates the sub-projectiles along the trajectory path, increasing the likelihood of multiple hits on surface targets while maintaining adequate dispersion coverage.
Solution Approach 2:
The invention transitions from a symmetric circular dispersion pattern to an asymmetric horizontal linear pattern through rotation. This asymmetric arrangement concentrates sub-projectiles along the direction of flight, increasing density on surface targets while reducing waste in vertical directions.

AI summary
A payload container for providing a horizontal dispersion pattern of sub-projectiles suitable for combatting surface targets is in the form of a cylinder and includes at least two sub-projectiles arranged in a core enclosed by a container wall, wherein the sub-projectiles are linearly disposed. In addition, a projectile and use of the same include at least one payload container or a plurality of sequentially arranged payload containers displaced by a displacement angle relative to each other. The displacement angle is predetermined in such way so that the sub-projectiles are vertically lined at the time when the mechanical force from the carrier shell disappears and the sub-projectiles are spread to the left and to the right, providing a horizontal dispersion pattern.
