Abstract

Abstract An anti-material projectile which fragments wholly or in part due to impact shock on hitting a target thereafter penetrating the target causing damage. The projectile is preferably high density frangibile alloy having a ratio of compressive to tensile strength of 20 to 1. The projectile is useful against soft targets such as aircraft as well as armor targets where initial impact is at the armor plating. The projectile may be a composite of pyrophoric tip (41c) with a projectile body (41a) of frangible alloy and an armor piercing alloy base (41b).

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 43 words
An explosive-free anti-materiel projectile characterised in that it relies for its destructive capability upon whole or partial structural fragmentation induced by impact shock at the target, followed by forward expansion of the clustered fragments under residual kinetic energy and combustion of structural components.
Claim 2
Dependent Claim 43 words
An explosive-free anti-materiel projectile characterised in that it relies for its destructive capability upon whole or partial structural fragmentation induced by impact shock at the target, followed by forward expansion of the clustered fragments under residual kinetic energy and combustion of structural components.
Claim 3
Dependent Claim 16 words
A projectile according to claim 1 having a compressive strength of over 15,000 kg/cm 2 .
Claim 4
Dependent Claim 19 words
A projectile according to claim 1 or claim 2 having a tensile strength of approximately 800 kg/cm 2 .
Claim 5
Dependent Claim 20 words
A projectile according to any preceding claim having a ratio of compressive strength to tensile strength of a approximately 20:1.
Claim 6
Dependent Claim 17 words
A projectile according to any preceding claim having a density from 7.8 to 19 g/cm 2 .
Claim 7
Dependent Claim 16 words
A projectile according to claim 5 having a minimum density of 15 g/ cm 3 .
Claim 8
Dependent Claim 13 words
A projectile according to any preceding claim in which the alloy comprises tungsten.
Claim 9
Dependent Claim 14 words

Claim 10
Dependent Claim 19 words
A projectile according to any of claims 1 to 5 in which the alloy is copper infiltrated sintered tungsten.
Claim 11
Dependent Claim 15 words
A projectile according to any preceding claim in which the projectile has a pyrophoric tip.
Claim 12
Dependent Claim 27 words
ll. A projectile according to any preceding claim comprising an impact-frangible main body portion (41a), a high density armor piercing base (41b), and a pyrophoric tip (41c).
Claim 13
Dependent Claim 38 words
A projectile according to any of claims 1 to 10 comprising an impact-frangible main body portion (41a) and tip (41c), and a high density high strength alloy base (41b) suitable for the penetration of an airframe and/or armor.
Claim 14
Dependent Claim 21 words
A projectile according to any preceding claim having a high strength high density alloy base arranged for receiving a tracer .(62).
Claim 15
Dependent Claim 18 words
A projectile according to claim 13 having a self destruct propellant charge (72) cooperating with the tracer (62).
Claim 16
Dependent Claim 27 words
A round of ammunition comprising a projectile according to any preceding claim, a discarding sabot (14) for the projectile, and a cartridge (20) for firing the projectile.
