Definitions

  • the present invention relates to a multiple component penetrator projectile comprising a body component and a tail component joined to one end of the body component, the latter consisting of frangible tungsten material.
  • a penetrator projectile of this type is shown in EP-A-51375, published 12.05.82, this document being an intermediate document coming thereby within the provisions of Articles 54(3) and 89 EPC.
  • the body component (mid-section) consists or a frangible tungsten alloy whereas the tail component consists of a high strength tungsten alloy or equivalent metal commonly used for armor-piercing projectiles.
  • frangible material means a material which, under high velocity impact against a target, will break into small fragments while penetrating the target. While frangible materials can penetrate light armor and break up into small fragments, generally they are difficult to machine using conventional machining techniques.
  • the multiple component penetrator projectile of the afore identified prior art document has a cavity in its tail section for a tracer and in some instances such cavities also can hold a self-destruct mechanism to avoid hazards to friendly personnel, equipment or installations from projectiles not hitting the target.
  • the tail component consisting of high strength tungsten alloy or equivalent armor-piercing metal is used in order to permit the defeat of spaced multiple plate targets as represented. For example, by aircraft or helicopters equippped with armored cockpits or other protected components.
  • a multiple component penetrator projectile comprising a body component and a tail component joined to one end of the body component.
  • the latter consisting of a high hardness metal for instance sinter tungsten carbide and the tail component consisting of a high density metal for instance sinter tungsten or uranium 238.
  • FR-A-1 231 010 there is disclosed a multiple component penetrator projectile of which the tail component consists of tungsten alloy with a high content of tungsten or a material with at least the density of the body but less expensive and more machinable.
  • frangible materials are known.
  • frangible alloys of tungsten are known, such as 98W-2Ni, 97W-2.1 Ni-0.9Fe, and 90W-10Mo and tungsten doped with about400 ppm of nickel. All of these materials will penetrate a target such as a 2" (5 cm) thick steel armor plate, when fired at a high velocity such as from an anti-tank gun, then break into small fragments while penetrating or exiting from the plate.
  • Such materials while exhibiting the desired frangibility, have a tendency to form cracks when cavities are machined into the tail of the penetrator for tracer or self- destruction mechanisms. The cracks can cause premature fragmentation.
  • Heavy alloys are that class of two phase multi-component tungsten alloys containing nickel and at least one other metal and in which one phase is essentially tungsten and the other phase is a solid-solution of nickel, tungsten and the other metal or metals. It has been found that the heavy alloys are suitable for forming the tail component of a penetrator where a cavity is to be machined into the tail component. These heavy alloys have a density of at least about 16.7 grams/cc, therefore these alloys containing at least about 88% tungsten and the balance being nickel and other metals such as copper, molybdenum, iron, titanium and the like. A particularly preferred alloy is 97.3W-1.35Ni-1.35Fe.
  • a cross section of penetrator 10 comprising a body component 12, and a tail component 14 containing a tracer cavity 16.
  • Nose component 18 is of the same material as the body component 12 and can be either fabricated in one section comprising both the body component 12 and nose portion component 18 or if desired the pieces can be fabricated separately and the nose component 18 can be joined to one end of body component 12.
  • the method of joining the components can be brazing, inertial welding and the like.
  • the tail component 14 is similarly joined to the opposite end of body component 12.
  • Frangible materials as indicated in claim 1 are used for the body portion 12 and nose component 18. Each of these materials will penetrate the targets up to about 2" (5 cm) thick steel and will break into small pieces upon exiting the target.
  • the tail portion is the heavy alloy as previously described having a density of at least 16.7 grams/cc.
  • Body component 22 is a frangible material.
  • the nose component 24 is a tungsten base alloy such as 98W-2Ni, 97W-2.1 Ni-0.9Fe or 90W-10Mo.
  • Tail component 26 is essentially identical to the tail portion of Fig. 1, that is, it is a machinable heavy alloy.
  • the penetrator 20 also contains a tracer cavity 28.
  • Body component 32 is made of the aforementioned annealed tungsten or tungsten containing 400 ppm of nickel.
  • the tail component 34 and one section 36 of the nose component 38 are made of the machinable heavy alloy.
  • a second section 40 extends from the first section 36 to serve as a windscreen and is a lighter weight material such as aluminium or a ceramic material.
  • the nose component 38 thus is comprised of a first section 36 which is machined to enable attachment of the second section 40 which serves as a windscreen.
  • the cavity 42 is shown in the tail component 34.
