Small Caliber Shaped Charge Projectile Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current small caliber projectiles used in handheld weaponry lack sufficient penetration capacity to effectively engage lightly armored vehicles and body armor without requiring additional, bulky weaponry.
Innovation Solution
A small caliber projectile design incorporating a shaped charge explosive, featuring a separable jacket, a main charge, a liner, and a striker, with an optional booster charge, is developed to enhance penetration capabilities while maintaining a compact size, allowing for limited but increased penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional small caliber projectiles are used, then the weaponry remains compact and portable, but the penetration capacity against armored targets is insufficient
Solution Approach 1:
The projectile is divided into distinct functional segments: a separable jacket containing the shaped charge explosive, a liner, a booster charge, and a striker. This segmentation allows each component to be optimized for its specific function while maintaining overall compactness when assembled in small caliber configurations.
Solution Approach 2:
The patent employs nested positioning where the liner is positioned within the explosive charge cavity, the booster charge is nested within the jacket, and the striker is positioned to impact the booster charge. This nested arrangement maximizes penetration capability within the constrained dimensions of small caliber projectiles.
2Strength
If shaped charge explosive is incorporated into small caliber projectiles, then penetration against armored targets is enhanced, but the projectile size and weapon bulk increase
Solution Approach 1:
The shaped charge explosive is concentrated in a specific localized cavity within the projectile rather than being distributed throughout. The explosive is positioned specifically to create a focused jet toward the target, providing high penetration capacity in a small volume while maintaining compact overall projectile dimensions suitable for small caliber weapons.
3Strength
If a complete shaped charge system with separable jacket, main charge, liner, and striker is used, then penetration effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The projectile is designed with a separable jacket that can be assembled and disassembled, allowing the shaped charge components to be manufactured separately and then configured together. This segmentation enables specialized manufacturing processes for each component while simplifying quality control and assembly procedures.
Solution Approach 2:
The jacket serves multiple functions: it contains the shaped charge explosive, provides structural protection, and can be separably assembled with other components. This multi-functionality reduces the number of separate components needed, thereby simplifying the overall manufacturing process while maintaining penetration effectiveness.

AI summary
This application discloses a shaped charge firearm projectile that includes a two-piece jacket that defines an internal cavity with an opening in the front side of the jacket that is part of the internal cavity, a detonator positioned in the internal cavity, a striker passing through the opening with one end positioned outside of the internal cavity and the other end positioned near the detonator inside of the internal cavity positioned to detonate the detonator when the striker impacts a target with sufficient force, and a main charge positioned in the internal cavity with the main charge and the jacket defining an air-filled chamber located between the front side of the jacket and the main charge, where the striker extends into the main charge.
