Hunting Projectile Bore System for Expansion and Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectiles for hunting suffer from inadequate expansion and penetration, leading to inefficient target engagement and potential health risks due to lead toxicity, while also requiring excessive force to overcome friction between the sabot and firearm bore.
Innovation Solution
A projectile design featuring a penetrator and body with a bore system that allows for deformation upon impact, using non-lead materials like AISI 1215 steel, and a sabot with reduced frictional engagement to enhance aerodynamics and penetration, allowing for humane hunting and minimizing lead toxicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional lead projectiles are used to enhance deformability, then expansion capability is improved, but health risks due to lead toxicity increase
Solution Approach 1:
The patent changes the material parameter from lead to non-toxic alternatives such as copper or copper alloys, maintaining the required deformability and expansion characteristics without the harmful toxicity effects of lead
Solution Approach 2:
The patent employs composite construction with a copper or copper alloy jacket and a separate penetrator core, combining the beneficial properties of different materials to achieve both expansion capability and penetration performance without using toxic lead
2Adaptability or versatility
If a sabot is used to fire projectiles smaller than the bore, then compatibility with firearm bore is improved, but frictional force between sabot and bore increases
Solution Approach 1:
The sabot is designed with different surface properties at different locations, featuring a smoother interface surface in the contact region with the firearm bore to reduce friction, while maintaining structural integrity and support functions in other regions
Solution Approach 2:
The patent replaces the traditional mechanical friction-based sabot interface with a reduced-friction design that minimizes contact resistance, allowing the projectile-sabot assembly to move through the bore with less force requirement
3Length of moving object
If conventional projectiles are used for hunting, then penetration is achieved, but expansion capability is insufficient
Solution Approach 1:
The projectile is divided into functionally distinct segments: a penetrator portion optimized for penetration and a jacket portion designed for expansion, with the jacket featuring circumferential grooves or segmentation that facilitate controlled expansion upon impact while maintaining penetration capability
Solution Approach 2:
The projectile design incorporates dynamic expansion characteristics where the jacket material and structure are engineered to transition from a rigid state during flight to an expanding state upon target impact, achieving both penetration and expansion performance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The projectile achieves improved expansion and penetration, reducing the need for excessive force during loading and ensuring humane hunting, while eliminating lead toxicity concerns by using non-lead materials and a sabot design that minimizes frictional resistance.
Implementation Method 1
The penetrator may be positioned adjacent to a first end of the body. The penetrator may be secured to the body... The body may have one or more portions to promote deformation of the body upon the penetrator impacting the target.
Implementation Method 2
The interaction of the projectile and the sabot results in the sabot frictionally contacting the contours of the bore as the projectile and sabot are loaded and forced into the firearm.
Data Source
AI summary
An improved projectile having a penetrator and a body is disclosed. The penetrator is secured to the body. Upon impacting a target, the penetrator travels into the body and deforms the body. The body optionally has one or more portions, such as slots in the body, to promote deformation of the body upon the penetrator impacting the target. The body optionally has a bore extending at least partially therethrough that permits attachment of the penetrator at a second end of the body opposite the first end.
