Definitions

  • the invention relates to a projectile with a shell and a front with the Bullet casing can be connected via a screw connection to the head igniter according to the characteristics of the preamble of claim 1.
  • the invention further relates to a method for the manufacture of such a projectile.
  • artillery shells are increasingly required to be delivered to the respective customer with a detonator.
  • the detonator In addition to its previous function, the detonator must therefore close the projectile in the target area ignite or bring to effect, also the function, the projectile during storage and reliably seal and transport against ingress of moisture, the connection being subjected to the usual stresses (temperature changes, vibrations etc.) must withstand.
  • This is currently achieved in that commercial sealing Anaerobically curing sealants are used, some of which at the same time as Belay means work.
  • the respective sealant or securing agent is used before Screwed together applied to the external thread of the igniter.
  • a disadvantage of these bullets provided with a preassembled head detonator is, however, that disassembly of the igniter after curing of the sealant hardly is more possible because the adhesive force in the thread is so high that a non-destructive It is usually not possible to detach the igniter. Because those commonly used today Head detonators have a heavy-duty external thread, but they do there is a connection between the rear part of the Detonator and the detonator tip also via a screw connection, which when unscrewing of the detonator can be damaged relatively easily due to the large starting torques can.
  • the present invention has for its object a floor of the aforementioned Specify type, the top match is easily replaced by a new one Detonator - for example, still in the combat position by the appropriate soldier exchange leaves. A method for producing such a projectile is also intended be disclosed.
  • the invention is essentially based on the idea that between the external thread and the mouth thread not a hardening compound as a sealant as before, but a permanently elastic sealant is arranged.
  • the permanently elastic Sealant e.g. applied in viscous form to the external thread of the igniter.
  • the detonator can then be used or at a suitable later time (e.g. after several months) are screwed onto the shell. This completes the thread gap between the outer and outer threads of the projectile filled in and gives a good sealing effect, without the detachability of the igniter to affect negatively.
  • the use of the permanently elastic sealant also has the advantage that existing igniter can still be used. A change in A connection between the rear part of the igniter and the igniter tip is therefore not necessary.
  • Pre-coated detonators can be screwed to the shell immediately or up to be stored for several years at room temperature.
  • the figure shows the front area of a spin-stabilized artillery projectile denoted by 1.
  • the projectile 1 comprises a projectile casing 2 in which explosives 3 is located, and a detonator 4.
  • the detonator provided with an external thread 5 4 is screwed into an internal thread (mouth thread) 6 of the projectile casing 2.
  • a permanently elastic sealant 7 arranged between the threads of the two threads 5, 6 is a permanently elastic sealant 7 arranged.
  • the head igniter 4 is made up of an igniter tip 8 and a detonator tail 9 together, which encloses an amplifier charge 10.
  • Detonator tail 9 and detonator tip 8 are via a relatively weak threaded connection 11 connected to each other, which is secured via an anti-rotation device 12.
  • the permanently elastic sealant 7 is first viscous Form on the external thread 5 of the igniter 4 and / or on the mouth thread 6 of the shell 2 applied. All that is required is the thread that is pre-coated should be clean and fat-free. Then the pre-coated Head fuze 4 are then immediately screwed to the shell 2.
