Definitions

  • the invention relates to a projectile with an explosive stored in a projectile casing, with a detonator and with means by which the explosive is supported on the detonator.
  • cardboard disks are placed between the detonator and the explosive.
  • These cardboard disks have the disadvantage that they do not ensure that the space between the detonator and the explosives is filled. This is because the size of the room depends essentially on the tolerances of the explosive body or the ground igniter, so that the size of the space between the detonator and the explosive can hardly be determined in advance. If there is a gap between the explosive and the detonator, the explosive can hit the detonator when it is knocked. This can cause misfires. Such shocks occur when the projectile is fed to the weapon and when it is fired of the projectile or also for necessary impact and impact tests of the projectile.
  • the object of the invention is to achieve a play-free support of the explosive on the detonator in a bullet of the type mentioned in a technically simple manner despite the inevitable tolerances.
  • the above object is achieved in a projectile of the type mentioned at the outset in that the explosive is supported on the detonator via a rigid foam layer foamed between them.
  • the support is not provided by a prefabricated component, but by a hard foam layer that foams between the explosive and the ground igniter.
  • the hard foam layer foams up by itself in such a way that it lies tightly on the one hand on the explosive and on the other hand on the detonator regardless of the given tolerances.
  • the space between the detonator and the explosive is thus completely filled without first having to determine how large the space between the explosive and the detonator is in the individual case.
  • the hard foam layer dampens impacts acting on the explosive in such a way that there is no unwanted ignition of the explosive.
  • Rigid foam layer formed by a rigid polyurethane foam.
  • the hard foam layer closes cracks existing between the detonator and the explosive. If the detonator ignites during a test of the detonator safety device of the detonator, the resulting gases cannot reach the explosives. Because they are insulated by the hard foam layer. The hard foam layer is able to absorb the resulting gases.
  • the hard foam layer also has the advantage that it covers the explosive so that it does not crumble during impact tests or impact tests and also when the projectile is fired.
  • 1 explosive 2 is inserted into a projectile jacket.
  • a detonator 4 projects into a cavity 3 of the explosive 2.
  • This detonator contains a detonator safety device.
  • a housing 5, in which the igniter 4 is accommodated, is screwed into the shell 1.
  • a foamed polyurethane rigid foam layer 6 This surrounds the detonator 4 in a cup-like manner and extends with a ring edge 7 up to the projectile casing 1.
  • the rigid foam layer 6 is produced in that an appropriate plastic mass is applied to the explosive 2 is applied and then the igniter 4 or the housing 5 is screwed in immediately. The plastic then foams in the space between the explosive 2 and the detonator 4, whereby it lies close to the explosive 2 and the detonator 4. At the same time, it closes a crack 8 existing on the circumference of the housing 5.
  • a projectile tip 10 is placed on the projectile jacket 1.
  • a fire charge 11 is accommodated in this.
  • This load 11 is also fixed by means of a foamed polyurethane rigid foam layer 12.
  • the exemplary embodiment according to FIG. 2 largely corresponds to that of FIG. 1.
  • a polyamide ring 13 is placed on the explosive 2. This improves the refraction of a shock wave. It also ensures an approximately uniform thickness of the rigid foam layer 6.
  • the hard foam layer 6 extends into the crack 8.
  • the ring 13 can also consist of steel or another explosive-compatible material.
  • the igniter 4 is arranged on the tip 10 of the projectile. This is screwed into the shell 1. The screwing in takes place immediately after the introduction of the plastic compound, which forms the hard foam layer 6 after foaming.
