Projectile Fragmentation Angles via Asymmetric Ring Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectiles with ring-shaped elements designed for fragmentation often propel fragments perpendicularly to the longitudinal axis, resulting in a limited effective range and inefficient scattering, as fragments directed towards the ground cause collateral damage and those of low mass do not contribute to the target area.
Innovation Solution
The design arranges the freely projecting ends of fragments in a common orthogonal plane diverging from the ring-shaped connecting portion's plane, allowing for inclined fragmentation, which changes the propelling direction and enhances the effective range by angling the fragments between 5° and 70°, particularly between 15° and 45°, relative to the longitudinal axis, and using grooves for controlled breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If ring-shaped elements are designed with predetermined break points to produce fragments of predefined size and mass, then fragment mass uniformity is improved, but the fragments are propelled substantially perpendicularly to the longitudinal axis resulting in limited effective range
Solution Approach 1:
The ring-shaped elements are designed with asymmetric geometry where the freely projecting ends of the fragments form an angle with respect to the plane of the ring-shaped connecting portion. This asymmetric configuration causes fragments to be propelled at angles between 5° and 70° (particularly 15° and 45°) relative to the longitudinal axis of the projectile body, thereby extending the effective range and improving scattering efficiency while maintaining uniform fragment mass through predetermined break points
2Manufacturing precision
If fragments are propelled perpendicularly to the longitudinal axis, then fragment mass control is achieved, but scattering efficiency deteriorates as many fragments are misdirected towards the ground causing collateral damage
Solution Approach 1:
The asymmetric design of ring-shaped elements with angled freely projecting ends redirects fragment propulsion away from the perpendicular direction. This asymmetry ensures that fragments are propelled at optimized angles (5°-70°, particularly 15°-45°) relative to the longitudinal axis, improving scattering efficiency and reducing ground-directed fragments that cause collateral damage, while predetermined break points maintain fragment mass control
3Ease of manufacture
If ring-shaped elements are designed as disc-shaped with fragments in the same orthogonal plane, then manufacturing simplicity is maintained, but fragment propelling direction is limited to perpendicular to the longitudinal axis
Solution Approach 1:
The design transitions from traditional disc-shaped ring elements with fragments in the same orthogonal plane to asymmetric ring-shaped elements where freely projecting ends are angled at 5°-70° (particularly 15°-45°) relative to the plane of the ring-shaped connecting portion. This asymmetric configuration maintains manufacturing simplicity while significantly extending fragment propelling range and improving scattering efficiency
