Definitions

  • the present invention relates to materials for multiple component penetrators and penetrators using same. More particularly it relates to kinetic energy penetrators having a frangible component and a machinable component.
  • frangible materials are known. For example, in United States Patent Application S.N.250,334, there is described a frangible tungsten material.
  • 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.
  • penetrators have a cavity in the rear section for a tracer and in some instances the cavity also holds a self-destruct mechanism. If the rear section is made of the frangible material, the cavity can cause the material to break apart prematurely. Additionally,,in some, penetrators it is desired to provide a windscreen of a lighter weight material.
  • a kinetic energy penetrator having a center component of a frangible material and a rear heavy alloy machinable component and which can optionally have a number of different nose components would provide flexibility in manufacture, overcome some of the problems associated with the prior art and constitute an advancement in the art.
  • a penetrator comprising a body component of a frangible tungsten material and a heavy metal tail component joined to one end of the body component.
  • a nose component generally having a conical shape extends from the opposing end of the body component and has the same composition as the body portion.
  • a penetrator having the above-mentioned body and tail components and a nose component of a material different than said body component joined to the opposing end of the body portion.
  • a projectile having the above-mentioned body and tail components and having a nose component comprised of two sections.
  • the first section is a machinable tungsten portion joined to the end of the body component opposite to the tail component.
  • a relatively low density second section is joined to and extends from the first section and forms the windscreen and has a different composition than said first section.
  • frangible materials are known.
  • the annealed tungsten as disclosed in U. S. Patent S.N.250,334, which is incorporated by reference herein is the preferred material.
  • other alloys of tungsten are frangible, such as 98W-2Ni, 97W 2.lNi-0.9Fe, and 90W-10Mo and tungsten doped with about 400ppm of nickel. All of these materials will penetrate a target such as a 2" 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 multicomponent 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. It is preferred to use heavy alloys having 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 previously described are used for the body portion 12 and nose component 18. Each of these materials will penetrate the targets up to about 2" 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 97W 2Ni, 98W 2.lNi 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 aluminum 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.
