Definitions

  • the invention relates to a spin-stabilized carrier projectile of the type specified in the preamble of claim 1.
  • Such projectiles are known for example from DE 3 608 107 C 1.
  • a brake sail is provided as the braking element, which is equipped point symmetrically on its outer edge with a number of concrete centrifugal masses.
  • the brake sail must be housed in the floor so that the individual masses are as far as possible on the outer edge so that they can be thrown out radially when a gap is formed between the floor and the last submunition floor and then open the brake sail.
  • additional masses should advantageously be used in addition to the masses mentioned.
  • a disadvantage of the known device is above all that both the manufacture of the brake sail with the specifically arranged masses and the packaging of the sail in the floor of the floor are relatively complex.
  • the invention is therefore based on the object of further developing a swirl-stabilized carrier projectile of the type mentioned at the outset in such a way that the brake element to be used is simple to manufacture and is easy to accommodate in the floor of the storey.
  • Fig. 1 denotes a spin-stabilized carrier projectile, which was fired for example by means of a gun, not shown.
  • this projectile 1 contains two target-detecting submunitions which are ejected from the projectile 1 at a predetermined point in time.
  • the submunitions 20 and 30 and the floor 40 of the projectile 1 fly towards one another.
  • the submunitions 20 and 30 reduce their speed to predetermined values. Since the projectile floor 40 continues to fly at a constant speed, there is often a collision between the projectile floor 40 and the submunition body 30 and thus an instability in the flight behavior of these projectiles.
  • Fig. 2a the side view of a corresponding floor is shown in cross section.
  • 41 means the base piece, which generally consists of metal, 42 a cavity arranged in the base piece and 43 the braking element, which is arranged in the cavity 42 until the submunitions 20 and 30 are ejected.
  • the braking element which consists essentially of a fabric disc z.
  • B. consists of polyamide or a plastic film corresponding tensile strength, is screwed to the bottom piece 41 with screws 44.
  • FIG. 2b shows the braking element in its unfolded state.
  • the unfolding process It proceeds as follows: After the ejection process, the submunitions 20 and 30 and the floor 40 fly one behind the other without a mechanical connection. Due to the projectile twist, the fabric brake disc 43 is now pulled outward and thus delays the outflow surface of the projectile floor 40. As a result, the projectile floor remains very quickly behind the submunitions 20 and 30, so that the submunition bodies can no longer be influenced by the projectile floor.
  • FIG. 3 shows a top view of a first brake slide according to the invention according to FIG. 2b seen from the rear.
  • the brake disc is again 43 and the fastening screws are designated 44.
  • the fastening screws 44 preferably do not directly press the brake disk 43 against the base piece 41 (FIG. 2), but a washer 45 (for example made of metal) is pressed against the base piece 41.
  • 4 shows a second brake disk 43 'according to the invention.
  • 432 denotes a seam band, which has the task of preventing the brake disc from tearing in its edge region 431 during the high rotations of the floor 40
  • a further stability of the fabric brake machine 43 ' is achieved by additional belt straps 434, which are preferably arranged in a cross shape.
  • Polyamide has proven to be a particularly good material for both the webbing and the hem band.
