Definitions

  • the invention relates to a ballistic projectile according to the preamble of claim 1.
  • a bomb according to GB-PS 1 605 340 has to combat concrete targets such as runways, a shaped charge for pre-drilling the runway and an explosive projectile as a successor to the shaped charge is a detonator provided that this is the only way to ensure the proper formation of the shaped charge effect.
  • a piezoelectric igniter is proposed, which lies directly on the back of the explosive charge of the shaped charge. This secondary ignition is critical since it cannot be guaranteed whether the firing pulse of the piezo igniter is disturbed or destroyed by the explosive pulse of the explosive charge.
  • the explosive charge of the explosive device is ignited in a continuation of the above-described secondary ignition via a pyrotechnic delay unit - starting from the propellant charge. The detonation of the explosive charge is therefore relatively imprecise and not very reliable.
  • a characteristic feature of GB-PS 1 605 340 are consequential ignitions with regard to the propellant charge and the explosive charge. The invention makes no use of this secondary ignition.
  • DE 35 44 528 C1 has a functional principle corresponding to GB-PS 1 605 340, namely a hole is pre-drilled in concrete for an explosive projectile using a hollow charge.
  • the propellant charge is therefore small and corresponds to the caliber of the explosive device.
  • the invention has for its object to provide a floor of the type mentioned that in concrete and the like. has a significantly improved penetration performance, so that it is suitable for combating bunkers, shelters or the like.
  • the advantages achieved with the projectile according to the invention are that it has a comparatively good penetration performance in concrete or the like, so that bunkers, shelters or the like can be optimally controlled.
  • the projectile according to the invention has improved functional reliability, ie a reduced risk of bouncing through an optimized penetrator contour and a reliable detonator function
  • the outer contour and the mass of the projectile according to the invention preferably correspond to the corresponding values of conventional projectiles, i.e. the projectile according to the invention can advantageously be ballistically equivalent to the ammunition that is introduced, so that the firing tables of the ammunition that is introduced can be taken over.
  • the shot boards do not have to be determined by expensive tests first.
  • the scattering behavior or the accuracy of the projectile according to the invention can also correspond to the accuracy of the ammunition introduced.
  • the drawing shows an illustration of the projectile 10, which has a penetrator 14 in a projectile shell 12 of the appropriate caliber.
  • the projectile casing 12 consists of a casing body 16 which is integrally formed with a floor 18 and a ballistic projectile hood 22 which defines the tip section 20 of the projectile 10.
  • a proximity fuse 24 is arranged on the front of the ballistic projectile hood 22.
  • the proximity fuse 24 is provided with an electrical output 26, to which a connecting line 28 arranged by a dash-dotted line is connected.
  • the penetrator 14 has a solid ballistic head 20 with a flattened, sharply delimited end face 13 and a space 32 adjoining the ballistic head 30 to the rear, in which an explosive charge 34 is located.
  • the penetrator 14 has a bottom impact igniter 36 for igniting the explosive charge 34.
  • the bottom impact igniter 36 can be provided with a pyrotechnic or with an electrical delay. It can have a variable time function, ie the time function can be preset to a certain value or can be set by means of a suitable acceleration sensor device.
  • the length 31 of the head 30 corresponds to 2.3 times the diameter 15 of the penetrator 14. This length 31 in conjunction with the entire mass of the penetrator 14 ensures the required penetration performance in concrete.
  • the penetrator 14 designed in this way is fixed in the center of the projectile casing 12 by means of a moving floor 38 with a sealing ring 39 and by means of a guide ring 40.
  • the guide ring 40 rests with a counter stop designed as a circumferential collar 42 on a circumferential stop 44 formed in the projectile hood 22.
  • the guide ring 40 is consequently fixed axially immovably in the projectile casing 23.
  • the projectile hood 22 is screwed to the projectile casing 12 at 43.
  • the drive floor 38 is formed with a circumferential collar 46, which serves to fix the rear end section 48 of the penetrator 14.
  • the moving floor 38 is arranged so that it can move axially in the shell 12.
  • the space between the moving floor 38 and the floor 18 of the case body 16 of the projectile casing 12 is provided for a propellant charge 50.
  • the propellant charge 50 is ignited by means of a propellant charge lighter 52 which is in contact with the connecting line 28.
  • the projectile 10 thus consists of the projectile casing 12 with a ballistic projectile hood 22, and the sub-caliber penetrator 14, which is arranged in a protected manner in the projectile casing 12 and is provided with the explosive charge 34 and the ground impact detonator 36.
  • the penetrator 14 is fixed by means of the moving floor 38 and by means of the guide ring 40 inside the shell 12.
  • the penetrator propellant charge 50 serves to expel the penetrator 14 from the projectile casing 12.
  • the penetrator propellant charge 50 is ignited by means of the propellant charge lighter 52, which is connected to the proximity fuse 24 via the connecting line 28.
  • the proximity fuse 24 thus serves to initiate the propellant charge fuse 52.
  • the projectile casing 12, the penetrator 14 and the moving floor 38 are expediently made of high-strength steel because of the high loads that occur when the penetrator 14 is fired or ejected from the projectile casing 12, as is used, for example, for highly stressed components in other ammunition.
  • the ballistic projectile hood 22 or its front section and the proximity fuse 24 can be penetrated by the penetrator 14, but it is also possible to blow off the said front part of the ballistic projectile hood 22 and the proximity fuse 24 parallel to the ignition of the propellant charge 50.
  • a space 53 for a penetrator propellant charge 50 has a diameter 54 which corresponds to 1.5 times the diameter 15 of the penetrator 14.
  • the drive floor 38 is concave in the direction of the penetrator propellant charge 50 and, with its flange 56 curved on the floor, acts on the one hand as a cover for the space 53 and on the other hand as a drive disk for the penetrator 14.
  • the concave shape of the floating floor 38 also results in a gain in space for the space 53 and has a favorable stress distribution when supporting the entire floor 10 when firing and when the penetrator 14 is ejected from the shell 12
  • the penetrator 14 is a sub-caliber balancing projectile with a high initial speed, a straight trajectory and a high penetration rate.
  • the concave flange 56 increases the guide length of the penetrator 14 in the projectile casing 12, so that the penetrator 14 leaves the projectile casing 12 coaxially, that is to say has no or only a slight exit angle.
  • the sharp-edged end face 13 of the head 30 ensures that the penetrator 14 penetrates the concrete at an angle of ⁇ 90 ° even when it strikes concrete.
  • the proximity fuse 24 senses a target made of concrete and ignites the propellant charge lighter 52 at a suitable distance from the target.
  • the gases of the penetrator propellant charge 50 drive the propellant base 38 with the penetrator 14, the penetrator 14 being guided radially through the collar 46 and the guide ring 40.
  • the penetrator 14 penetrates the proximity fuse 24 and the projectile hood 22.
  • the drive floor 38 then strikes the guide ring 40 and the penetrator 14 leaves the drive floor 38 and the guide ring 40.
  • the time-delayed detonator function of the ground impact igniter 36 is started. Due to the great energy of the penetrator 14, it penetrates the target. After the penetration process, the ground impact detonator 36 ignites the explosive charge 34, as a result of which the head 30 and the sleeve 62 of the penetrator 14 are broken down into fragments.
  • the ballistic projectile 10 according to the invention is reliable in its function. It has only one component acting in the target, namely the penetrator 14.
  • the penetrator propellant charge 50 is large in volume and is ignited reliably by the proximity fuse 24. Mainly due to the massive head 30, the penetrator 14 has the mass required for the target penetration.
