Double Impact Bullet Internal Hammer Shock Wave Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double impact bullet systems lack a mechanism for delivering a mechanical kinetic phenomenon with a sharp rise time in secondary impact, limiting their ability to penetrate armor effectively.
Innovation Solution
A novel non-exploding double impact bullet design featuring an internal hammer and post with a clearance fit, allowing the hammer to slide within the fuselage, generating a high-pressure spherical shock wave upon impact, and utilizing materials like lead, uranium, tungsten, or high-density alloys to enhance penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional double impact bullet systems are used, then the structure is simple, but the rise time of secondary impact shock wave is not sharp enough
Solution Approach 1:
The internal hammer mechanism is designed as a dynamic system where the hammer can slide freely within the fuselage along the axis of symmetry. This dynamic configuration allows the hammer to respond rapidly to the initial impact and deliver a sharp-rised secondary impact to the target, achieving fast rise time without overly complex mechanisms
Solution Approach 2:
The bullet is segmented into distinct functional components: the nose cone for initial impact, the fuselage containing the hammer mechanism, and the hammer itself for secondary impact. This segmentation allows each component to perform its specific function optimally, with the hammer delivering a concentrated secondary blow that achieves sharp rise time
2Strength
If high-density materials are used in the hammer, then penetration ability is improved, but the weight of the bullet increases
Solution Approach 1:
High-density materials such as depleted uranium, tungsten, or tungsten carbide are used specifically in the hammer portion of the bullet where they are most needed for penetration. The nose cone and fuselage can use lighter materials, optimizing the overall weight-to-penetration ratio by concentrating high-density material only in the critical impact zone
Solution Approach 2:
The bullet employs composite construction combining different materials with complementary properties: high-density materials in the hammer for penetration, and other materials in the fuselage and nose cone for structural integrity and function. This composite approach achieves superior penetration ability while managing overall bullet weight
3Speed
If the hammer fits tightly in the fuselage, then structural integrity is improved, but the hammer cannot slide freely to deliver secondary impact
Solution Approach 1:
A clearance fit is introduced as an intermediary space between the hammer and fuselage walls. This small gap allows the hammer to slide freely along the axis of symmetry when forced by impact, while still maintaining sufficient structural integrity. The clearance fit mediates between the conflicting requirements of free movement and structural strength
4Duration of action of moving object
If the nose cone deforms plastically on impact, then energy is absorbed, but the hammer may not have time to deliver secondary impact
Solution Approach 1:
The nose cone is designed to undergo controlled plastic deformation as a preliminary action that initiates the hammer's forward movement. The deformation process itself helps drive the hammer forward along the axis of symmetry, ensuring that the secondary impact occurs within the available time window while still absorbing sufficient impact energy
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 internal hammer mechanism provides a concise short rise time shock wave pulse, enabling deeper penetration and damage to armor beyond previous systems, with the hammer delivering a secondary impact after initial plastic deformation of the nose cone.
Implementation Method 1
generating a high-pressure spherical shock wave upon impact
Implementation Method 2
the hammer will be forced forward towards the nose cone... delivering a secondary impact to the target
Implementation Method 3
The clearance fit is an engineering fit which enables the two parts to slide and or rotate when assembled
Implementation Method 4
The hammer diameter would be between one and ten mils less than the diameter of the inner annulus of the fuselage for a standard RC7 clearance fit
Implementation Method 5
utilizing materials like lead, uranium, tungsten, or high-density alloys to enhance penetration
Implementation Method 6
after initial plastic deformation of the nose cone
