Definitions

  • the invention relates to a penetrator for a sabot projectile consisting essentially of heavy metal, such as tungsten heavy metal or uranium, in particular depleted uranium, which has a larger diameter than the sabot surrounding the penetrator, the penetrator extending from its tip area up to is formed in one part of its rear region and a guide device is optionally connected to the rear region of the penetrator, and to a method for producing such a penetrator.
  • a depleted uranium is understood to be a natural uranium depleted of 235 U , which accumulates as a residue when enriching natural uranium.
  • the penetrator which is essentially arrow-shaped and has a much smaller diameter than the gun barrel, is surrounded by a larger diameter cage, which is also referred to as a sabot, through which the projectile is guided in the gun barrel. Behind the barrel mouth, the sabot detaches from the penetrator. Since the area on which the propellant charge acts is considerably enlarged by the propellant cage, it is possible to transmit very large propellant forces to the penetrator.
  • the exit speed of the penetrator at the end of the gun barrel can be 1000 - 3500 m / s. Since the penetrator is made of heavy metal, its impact force is very high and such penetrators therefore have an armor-piercing effect.
  • the penetrator must have great strength or hardness. This great strength, which enables the penetrator to penetrate the armor, again results in a great brittleness of the penetrator. Particularly in the case of bulkheaded armor, shock-like forces occur when the penetrator penetrates the armor, which in view of the Brittleness of the material of the penetrator entails a risk of breakage. It has been shown that the shaft of the penetrator frequently breaks. In this case the kinetic energy of the back part of the shaft of the penetrator is lost and the tip of the penetrator does not get through the armor.
  • the object of the invention is to reduce the risk of breakage of a penetrator and thus to improve the penetration effect of the penetrator.
  • the invention consists essentially in the fact that the penetrator has a lower strength and a greater toughness in a central region of its length than in its tip region and that it has a greater strength and lower toughness in the rear region than in its central region and a lower strength and a has greater toughness than in its tip area.
  • the strength of the tip with the greater strength being accompanied by greater hardness, is essential for penetration of the penetrator into armor and this strength is maintained.
  • the risk of breakage in the known penetrators mainly existed in the central area of the penetrator. Since, according to the invention, this middle region has a lower strength and, due to this lower strength, a greater toughness, a risk of breakage is avoided or at least reduced in this region.
  • the penetration of the penetrator into the armor is ensured by the high strength of the tip, the mass of the entire penetrator is used to penetrate the armor by avoiding the risk of breakage in the middle and rear area, and by the sufficient strength of the rear area of the stress taken into account by the propellant charge at launch.
  • the strength values decrease from the tip to the central region, the strength values expediently increasing again from the central region to the rear. Abrupt transitions of the strength values along the penetrator are thus avoided, which also acts in the sense of reducing the risk of breakage.
  • the penetrator has strength values of up to 1100-2000 N / mm 2 at its peak area, the strength values decreasing up to 900-600 N / mm 2 in its middle area.
  • the strength values can increase again up to 1300 N / mm 2 from the central region to the rear.
  • Such a penetrator is adapted to the stresses in a particularly favorable manner.
  • At least one pre-core can be connected to the tip region of the penetrator. This pre-core penetrates the armor first.
  • the penetrator After the first penetration path has been covered, the penetrator is therefore not stuck in the punched hole, but at the beginning of the penetration path only the preliminary core or the preliminary cores have penetrated into the armor.
  • the penetrator persists in its direction due to its inertia, but tilting moments still occur which, however, since the penetrator is not stuck in the hole, cannot lead to a break in the tip area of the penetrator.
  • the front cores detach from the penetrator without exerting a lateral moment on the penetrator. After a hole has already been punched using the front cores, lateral forces do not occur when the penetrator penetrates further.
  • the pre-core should penetrate the armor and therefore the pre-core must also have great strength.
  • the pre-core expediently consists of the same material as the tip area of the penetrator, and preferably this pre-core has at least the same hardness as the tip area of the penetrator. This ensures the penetration effect of the pre-cores.
  • the pre-core is expediently supported at the front end of the penetrator against the acceleration force.
  • the front core is supported at the front end of the penetrator.
  • the pre-core should only be connected to the penetrator to such an extent that the connection is sufficient for transport and flight.
  • the connection of the pre-core from the penetrator should not be hindered, so that side moments are avoided. It is even sufficient to connect the pre-core to the penetrator using a rubber cord.
  • the pre-core is expediently covered by a slippery hood attached to the front end of the penetrator.
  • This cover is inexpensive for ballistic reasons.
  • the cover can be formed, for example, by a slippery hood made of aluminum.
  • the slippery hood is screwed onto the front end of the penetrator and the preliminary core is supported on the hood with the interposition of a rubber ring.
  • the arrangement can be made so that at least two pre-cores are connected to the front end of the penetrator, the front pre-core having a smaller diameter than the rear pre-core and the rear pre-core having a smaller diameter than the end face of the penetrator so that the rear pre-core passes through an edge bead is centered on the end face of the penetrator and the front pre-core is centered by an edge bead on the end face of the rear pre-core and that the front pre-core is supported against the wind-slipping hood with the interposition of a rubber ring.
  • a method according to the invention for producing such a penetrator made of tungsten heavy metal essentially consists in that the penetrator is pressed from a powdery mixture of tungsten heavy metal and addition metals, such as iron, nickel, manganese, copper, cobalt and molybdenum, manganese-iron alloy, individually or in groups and is sintered, the proportion of the additional metals being increased in those regions of the sinter mold which correspond to the regions of lower strength of the penetrator.
  • the larger proportion of tungsten heavy metal results in greater strength and by increasing the proportion of the added metals while reducing the proportion of tungsten heavy metal, the toughness can be increased without the greater hardness.
  • the additional metals can also comprise microalloys of the elements cobalt and molybdenum individually or in a quantity of 0.00001-1%.
  • the mixture has 90-99% tungsten heavy metal, the remainder being additional metals, the higher amounts of tungsten being introduced in the areas of higher strength of the penetrator.
  • the sintered body can be hot or cold pressed and then subjected to a usual sintering temperature of 1100-1700 ° C. Sintering takes place either in a vacuum or under a protective gas, such as, for example, in an atmosphere of dry hydrogen, dissociated ammonia, nitrogen or inert gases or mixtures thereof.
  • the penetrator is cold-forged, in the areas of greater strength and lower toughness with a greater degree of deformation than in the areas of greater toughness and lower strength.
  • the penetrator is cold forged from a blank which has a larger initial cross section in the areas which correspond to the areas of greater strength of the penetrator than in the areas which correspond to the areas of lower strength of the penetrator.
  • the forged penetrator then has essentially the same cross section over its length.
  • the degree of deformation is in the areas in which the greater Strength is to be achieved, greater and this greater degree of deformation increases the strength during cold forming in these areas.
  • the forging of the tip area of the penetrator can be cold forged with a degree of deformation of up to 30% and the cold forging of the central and rear area of the penetrator can be carried out with a degree of deformation of 0-20%.
  • the cold forging of the penetrator can be carried out according to the invention, for example in the tip region of the penetrator with a degree of deformation of 6-20%, in the middle region with a degree of deformation of 2-12% and in the rear region with a degree of deformation of 4-16%.
  • a blank which is homogeneous over its length and consists of a homogeneous alloy of 90-99% tungsten heavy metal, the rest being iron, nickel, copper, manganese, cobalt, molybdenum, individually or in groups. In this case, the differences in strength are only achieved through the degree of deformation.
  • a sintered blank can also be used according to the invention, which is cold forged in the areas of its different composition with different degrees of deformation. If the cold forging is carried out with a greater degree of deformation in the areas of the blank in which the proportion of tungsten metal is larger and the proportion of addition metal is smaller, greater strength is achieved by the alloy composition and the degree of deformation.
  • the penetrator should be subjected to annealing at 800-1550 ° C. after cold forging.
  • the different strength values in the different areas can be generated by different partial heat treatment in these areas.
  • the penetrator is produced from a uranium alloy containing approximately 0.7% titanium and in the tip area at one Temperature of 400 - 600 ° C, preferably 400 - 500 ° C, in the central area at a temperature of 180 - 300 ° C, preferably 180 - 220 ° C, and in the rear area at a temperature of 350 - 450 ° C, preferably 350 - 400 ° C, partially heat treated.
  • the penetrator is produced from a depleted uranium alloy containing approximately 2% molybdenum and in the tip region at a temperature of 350-400 ° C., in the middle region at a temperature of 520-670 ° C., preferably 520-570 ° C, and in the rear area at a temperature of 400 - 550 ° C, preferably 400 - 450 ° C, partially heat treated. There may also be gradual transitions between the areas of different strengths.
  • the molding from the uranium alloy in question can be cast or sintered.
  • a penetrator made of depleted uranium can also be further solidified by cold working.
  • a uranium penetrator can therefore be cold-forged from a uranium blank which has been assembled and heat-treated in accordance with the invention and which has a larger cross-section in the areas which correspond to the areas of greater strength of the penetrator than in the areas which have smaller areas Correspond to the strength of the penetrator.
  • cold forging in the tip region of the penetrator can be carried out with a degree of deformation of up to 30% and cold forging in the middle and rear region of the penetrator with a degree of deformation of 2-12%.
  • Cold forging is expediently carried out in the tip region with a degree of deformation of 6-20%, in the middle region with a degree of deformation of 2-12% and in the rear region with a degree of deformation of 4-16%.
  • strength values of, for example, 1700 N / mm 2 can be achieved in the tip area, of 1450 N / mm2 in the rear area and 1200 N / mm2 in the middle area. Due to the low strength values in the middle area, the toughness is greater here.
  • the penetrator consisting of uranium, in particular depleted uranium, is heat-treated after the cold forging at a temperature of 300-800 ° C.
  • a heat treatment which is also referred to as recrystallization annealing, continuous transitions between the areas of different strength can be achieved and in this way metallurgical notches between these areas are avoided.
