Definitions

  • the invention relates to a full-caliber projectile with a projectile casing, a ballistic hood, arranged on the projectile casing guide tape and a propellant charge.
  • projectile active bodies of tungsten heavy metal construction splitter are enclosed by a projectile casing or projectile hood.
  • These "packaging elements”, also called parasitic or Balastmasse, do not contribute to the effect in the target. On the contrary, they hinder the bullet decomposition on impact at the target and thus the splitting and / or propagation considerably depending on the target distance.
  • the ratio of parasitic to active body mass is all the less favorable, the larger the caliber is or relatively low overall mass for the caliber.
  • Executed full caliber bullets in the range 25 mm to 30 mm generally have an active body mass fraction of ⁇ 70%.
  • the object of the invention is to provide a full-caliber bullet, which is preferably integrated with increasing the sealing effect and firing performance in a propellant charge molding and increases the effective mass fraction of the total floor mass.
  • the arrangement of the sealing and swirl transmission element according to the invention at the end of the ballistic tip At the end of the first third of the projectile length, provided in the transition to the tubular projectile body.
  • the propellant charge molding is adapted in the region of the projectile nose and the seal and swirl transmission element in the inner diameter of the seal and swirl transmission element, whereas the remaining projectile body is guided with caliber diameter in the propellant charge molding tube.
  • the projectile To handle safe to connect the projectile with the combustible propellant charge body and to ensure a uniform and adjustable Geunterausziehwiderstand in the propellant charge body, it is connected to the latter at the rear end of the seal and swirl transmission element (guide band) by means of a thread which is toscheert at the launching process in the propellant charge molding.
  • the projectile body following the seal and swirl transmission element is cylindrical and with the caliber diameter equal to its end, so that a long and smooth guidance results in the propellant charge body, which is only completed due to the inventively chosen the constructive position of the seal and swirl transmission element when this has reached a secure leadership in the gun barrel.
  • the projectile casing is designed as a tubular, end ballistic active body and consists of brittle tungsten heavy metal which, in order to achieve a required splintering performance no explosive filling as in ductile tungsten heavy metal is required.
  • the parasitic mass fraction of the total storey mass is reduced to 30% to 10% and the effective mass fraction of the projectile on the total storey mass is increased to 70% to 90%.
  • the ballistic tip and the swirl transmission and sealing element form a unit and are preferably made of fiber-reinforced plastic and non-positively and positively connected to the projectile body through openings in the injection-molding process.
  • the ballistic tip can be hollow and provided with predetermined breaking points.
  • seal and swirl transmission element can also be designed as a separate component.
  • the projectile body itself is tubular, wherein it is designed as a combat projectile preferably made of brittle tungsten heavy metal and for practice purposes of non or less end ballistisch effective material, for example steel.
  • the tubular projectile body is closed at its rear end by a Heckstopfen, in which a tracer can be integrated.
  • the Heckstopfen is the battle floor preferably made of a lightweight material to integrate as much effective mass in the projectile body itself and screwed with this, glued or pressed into this.
  • the projectile body can form a unit with the rear plug.
  • a so-called strangulation groove is arranged in the region of the rear end, which allows a frictional connection between the sleeve and projectile.
  • the sealing and swirl transmission element lying in the first third of the projectile can be integrated into the rear end.
  • a tracer version is compatible with all mentioned projectile variants.
  • a projectile 1 is integrated telescopically in a combustible propellant shaped article 14.
  • a trained as a guide band 3 seal and swirl transmission element is 35% to 45% of the projectile length I, starting from the front end 10 of a ballistic tip 2, disposed on the projectile casing 1.
  • the propellant charge molding 14 is formed in the region of the projectile nose 2 to the guide band 3 an inner diameter d 1 adapted to the guide band and a smaller inner diameter d 2 corresponding to the caliber diameter in the outer region of the caliber bullet casing 1.
  • the projectile casing 1 is designed as a tubular end ballistic active body and consists of explosive splinter formation in the target at a battle bullet of brittle tungsten heavy metal.
  • Rear side of the projectile is a Anzündtopf 15 with an electric ignition unit 16 is shown schematically within the propellant charge body.
  • Figures 2 and 3 show the combat projectile according to the invention with the tubular active body 1 of brittle tungsten heavy metal, which also forms the same caliber projectile body. Seen in the direction of flight, preferably a conical Ogivenform 9 having ballistic tip 2 with integrated guide band (seal and swirl transmission element) 3 molded plastic and connected via through holes 4 with the active body 1. At the rear end of the guide strip 3, a threaded connection 5 is shown to the propellant charge body. The hollow ballistic tip 2 is executed with longitudinal break points 8. The rear end of the active body is closed with a rear stopper 7.
  • Figures 4 and 5 show two variants of practice bullets in half section.
  • the variant shown in Figure 4 is constructed as the combat bullet according to Figure 2, but the projectile body 1 is provided of steel.
  • the thread on the integrated guide belt 3 of the ballistic tip 2 was also dispensed as on the predetermined breaking points.
  • FIG. 5 represents a special case.
  • the projectile body 1 forms a unit together with the rear end 7.
  • the ballistic tip 2 ' is molded from the front and simultaneously fills out the cavity formed as a blind hole of the projectile body.
  • this extraordinarily economical production variant does not allow predetermined breaking points in the tip.
  • the swirl transmission of the guide strip 3 integrated in the tip 2 ' is also effected here, as in FIGS. 2, 3 and 4, via passage openings 4 in the projectile body 1.
  • FIG. 6 shows a FAP projectile (Frangible Armor Piercing) with the tubular active body 1 of the ballistic tip 2 with predetermined breaking points 8, which is injection-connected via through-holes 4 to the active body.
  • the tail plug 7 'with tracer 11 closes the active body at its rear end and at the same time absorbs the swirl transmission and sealing element 6 as a conventional guide band.
  • a strangulation groove 12 in the rear stopper 7 allows the non-positive and positive connection with a standard cartridge case thirteenth
