Warhead Fragment Direction Control via Conical Cylindrical Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warheads, such as those described in GB 1,171,362 and US 2003/164108 A1, lack the ability to control fragment distribution direction and do not effectively utilize the outer surface for enhanced fragmentation effects.
Innovation Solution
A warhead design featuring a combination of cylindrical and conical portions arranged relative to the central axis, with a reflector to control fragment direction through back-spray or front-spray mechanisms, and varying fragment shapes and materials to achieve a lens effect for concentrated fragment distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cylindrical housing contains the fragmentation casing, then the warhead structure is simple, but the fragment distribution direction cannot be controlled and the outer surface effect is diminished
Solution Approach 1:
The warhead is divided into distinct functional segments: a front region with a conical portion for forward fragment distribution, a rear region with a cylindrical portion for backward fragment distribution, and intermediate regions. This segmentation allows independent control of fragment spray directions without requiring a completely complex redesign of the entire structure.
Solution Approach 2:
The invention transitions from a single-direction (forward-only) fragment distribution to multi-directional distribution by adding the conical portion that redirects fragments. This dimensional change in fragment trajectory control enables both forward spray through the conical section and backward spray through the cylindrical section, achieving variable direction control.
2Object-affected harmful factors
If the fragmentation casing is contained within a cylindrical housing, then the manufacturing is simple, but the outer surface effect is diminished and fragment impact is reduced
Solution Approach 1:
Different portions of the warhead are given different geometries optimized for their specific functions: the conical portion with its tapered shape is optimized for forward fragment spray and surface impact, while the cylindrical portion maintains structural integrity and enables backward spray. This local optimization of geometry enhances fragment impact effect in specific zones without requiring complete redesign of all components.
3Quantity of substance
If a single fragment distribution direction is used, then the warhead design is simple, but the ability to concentrate fragments in specific zones is lost
Solution Approach 1:
The warhead design enables dynamic control of fragment distribution patterns through the geometric configuration of the conical and cylindrical portions. By adjusting the angles and dimensions of these portions, the system can dynamically redirect shock waves and fragments toward different zones (forward, backward, or lateral), allowing concentration of fragments in specific target zones without requiring active control mechanisms.
