Definitions

  • the technical field of the invention is that of ammunition allowing the destruction of highly protected targets by a wall for example of concrete.
  • the body piercing this ammunition has a massive insert that is embedded in the body material.
  • This insert is made of a dense and mechanically resistant alloy chosen, for example, from refractory materials and their alloys (tungsten, tantalum, uranium).
  • the body material is formed of steel that is cast around the insert.
  • This ammunition has the disadvantage of being complex to manufacture. It is first of all delicate and expensive to produce a dense core of large diameter (greater than 90 mm) and having high mechanical characteristics in a reproducible manner (density greater than 13, yield strength greater than 1000 mega pascals). Indeed, these materials are used in the form of powders by compression techniques.
  • the patent WO-87/07708 discloses a medium-sized perforating projectile comprising an envelope and a core of heavy material. This projectile is completed by a cap of light material (plastic or aluminum) empty or filled with incendiary material. No insert or particular material is provided in the cap. The nucleus is located behind the projectile and a front annular rim is intended to impact the target in the first place.
  • the patent FR-2771496 discloses a conventional projectile comprising a heavy tungsten body provided with a front aluminum disintegrator element transmitting impact impact to the projectile. No insert is provided in this element before and no precision is made relative to its density relative to the body.
  • the munition according to the invention is moreover of simplified manufacture.
  • the invention relates to a perforating munition comprising a penetration body delimiting an internal cavity closed by a base, characterized in that the penetration body is made of a material having an elastic limit greater than or equal to 1200 Mega Pascals and comprises a front tip comprising at least one integral insert of the tip, insert made of a material with high mechanical characteristics, denser than that of the body and disposed in a housing opening outside the body, each insert being constituted by a bar substantially cylindrical housed in a bore body penetration.
  • the munition comprises a single axial insert having a front tip extending the penetration body.
  • the munition comprises a charge of propellant powder for ejecting the insert out of the penetration body.
  • the internal cavity contains at least one explosive charge.
  • a perforating munition 1 according to one embodiment of the invention comprises a penetration body 2 which delimits an internal cavity 3 closed by a base 4.
  • This ammunition could be an air / ground bomb or a missile or a military missile head. It will have a diameter greater than 100 mm and a length of the order of 1.5 m.
  • it may include a rear portion (not shown) incorporating a thruster which will confer a range or a given speed.
  • the internal cavity 3 contains an explosive charge 5 which can be initiated by a rocket 6 arranged in the vicinity of the base 4.
  • the rocket will be designed to ensure the detection of the crossing of a wall and then to initiate the explosive charge once this wall crossed.
  • Such rockets are well known to those skilled in the art. For example, one can refer to the patent US5255608 which describes such a rocket.
  • the penetration body 2 comprises a front tip 2a which is extended by a rear cylindrical portion 2b delimiting the internal cavity 3.
  • This body is made of a material with high mechanical characteristics, that is to say a material whose elastic limit is greater than or equal to 1200 Mega Pascals.
  • a material with high mechanical characteristics that is to say a material whose elastic limit is greater than or equal to 1200 Mega Pascals.
  • 35NCD16 steel may be used.
  • the front tip 2a comprises an insert 7 made of a denser material than that of the body 2.
  • This insert is made of a dense material with high mechanical characteristics.
  • a material with a density greater than or equal to 17 and having a yield strength greater than or equal to 1000 mega pascals will be chosen.
  • the munition according to the invention combines an ogive of large diameter (greater than 90 mm) and with a large perforating capacity with a steel body whose sole function is to ensure the carriage of the explosive charge and the maintenance of the perforating insert.
  • the front tip 2a comprises an axial bore 15 inside which is positioned the insert 7 having the form of a substantially cylindrical bar and made of a material denser than that of the body 2.
  • the front tip 16 of this insert has an ogive shape that extends the penetration body 2.
  • This insert 7 will thus have a diameter of the order of 30 to 40 mm for a penetration body 2 of diameter 90 mm. Its manufacture is thus facilitated.
  • the implementation of a tungsten alloy with high mechanical characteristics makes it possible to confer on this point a perforating character and not mere ballast. This improves the perforation capabilities of the ammunition for a given mass.
  • the ammunition shown in FIG. 2 also comprises a single insert 7 made of dense material disposed in an axial bore 15.
  • This insert 7 has an internal cavity 17 inside which is disposed a charge of propellant powder 18.
  • a device 19 for igniting this charge is housed in the body 2. It is connected by a wire connection 20 to the rocket 6.
  • the latter will then include a chronometric module or a proximity detection module (connected to an antenna not shown integral with the body's warhead 2) which will trigger the ignition of the propellant charge 18 before the impact on a target and at a distance from it of the order of 3 to 4 calibers.
  • a chronometric module or a proximity detection module connected to an antenna not shown integral with the body's warhead 2 which will trigger the ignition of the propellant charge 18 before the impact on a target and at a distance from it of the order of 3 to 4 calibers.
  • the propellant charge 18 will ensure the ejection of the insert 7 out of the penetration body 2. It will therefore be propelled towards the target.
  • the speed differential between insert 7 and the body 2 will be of the order of 200 m / s. Such an arrangement increases the perforation capabilities of the munition without increasing its speed.
  • the insert will ensure the drilling of a pre-hole in the target, the penetration body will then impact the target at this pre-hole.
  • the explosive charge 5 may be replaced by a load of a different nature, for example an incendiary charge or one or more explosive and / or incendiary sub-munitions ejected after perforation of the target.
