DE102005019534A1 - Process for converting from weapons with drawn pipes into ammunition made from smooth-bore weapons - Google Patents

Abstract

The invention relates to a method for reprocessing ammunition which can be produced from weapons with drawn pipes, with a wing-stabilized projectile and at least one slip-through sealing tape (8) in caliber (1) corresponding to smooth-bore weapons. DOLLAR A For this purpose, the invention proposes to remove the slipping by sealing tape (8) of the reprocessed ammunition by knocking, then a prefabricated annular sealing strip (9) extending in the axial direction separating slot (10) as long as to defer the ammunition until this is received by the existing groove-shaped recess (7) for the sealing strip (9), and then to close the separation slot (10) by a corresponding closure means.

Description

The The invention relates to a method for reworking weapons drawn pipes shootable Ammunition with a wing-stabilized projectile and at least a slipping seal tape in smooth-barreled weapons Caliber's shootable Ammunition.

Around from towed weapons wing-stabilized projectiles to shoot, it has long been known, instead of fixedly arranged on the ammunition body managerial and sealing tapes slipping sealing tapes, i.e. Sealing tapes, which rotatably in the tube passage of the projectile in a Dichtungsbandnut of the corresponding projectile are to be used.

There Especially with tank cannons more and more smooth-bore weapons for In many countries there is a desire to use existing ones drawn pipes shootable fin-stabilized Ammunition also from smooth-bore weapons with appropriate caliber to use up.

tries However, have shown that when shooting the with slipping seal bands provided ammunition from smooth-bore weapons considerable problems because the slipping seal tapes when pressed into the Caliber range of the smooth tube and so deformed at the tube passage be that on the carrier the sealing tape (e.g., a sabot or projectile casing, etc.) inadmissible high voltages are applied, destroying the carrier to lead can. The slipping seal tape must therefore usually before the shoot removed the ammunition from smooth-barreled weapons and through a new sealing tape be replaced.

For this has already been proposed, the slipping seal tape Turn off the existing ammunition and a new sealing tape to spray.

adversely in such a method, however, that at großkalibriger Armored ammunition of caliber of e.g. 105 mm both the fixation for one Turning as well as the handling of the ammunition (which has a length of about 1 m possesses) extraordinarily difficult and therefore expensive. In addition, during a turning process and an injection process that takes place under heat, the explosives, pyrotechnic Cargoes etc. taken from the cartridge or the makeover must be under Consideration of elaborate security measures are made.

Of the Invention has for its object to provide a method with whose help is a reworking of weapons that can be fired from firearms in lockable from guns Ammunition easily possible is.

These The object is achieved by the Characteristics of claim 1 solved. Further, particularly advantageous embodiments of the invention reveal the dependent claims.

The Invention is based essentially on the idea of slipping Sealing tape of the reprocessed ammunition by knocking off remove, then a prefabricated ring-shaped Sealing strip with separation slot extending in the axial direction to delay the ammunition until this of the existing groove-like Recess for the sealing tape is picked up, and then the separation slot to close by a corresponding closure means.

The inventive method not only has the advantage that it is very easy to cost, but the makeover can also be done without any special security restrictions performed on charged cartridges become. This makes it possible the makeover even without special tools or machines in to carry out the depots in which the old ammunition is stored.

Around an additional To obtain protection against gas penetration at firing, has it proved to be advantageous if the prefabricated sealing strip a sloping has extending separation slot.

The prefabricated sealing tape can be characterized by mechanical machining a pipe or rod section a usable as a sealing strip plastic or produced by injection molding become. As material for the prefabricated sealing strip may, for example, polyamide, in particular PA6, to be used.

Further Details and advantages of the invention will become apparent from the following explained with reference to figures Embodiments.

It demonstrate:

1 a side view of the bullet-side region of a cartridge with a sabot projectile with cut off sealing strip;

2 one out 1 corresponding side view, in which the projectile is provided with a sealing strip, which has a sloping separation slot;

3 . 4 an enlarged front view and a longitudinal section through the in 2 With 9 designated sealing tape;

In 1 is with 1 a cartridge called, which can be fired from a weapon with a drawn pipe sabot projectile 2 Contains a wing unit, not shown. The sabot projectile 2 consists in known manner of a subcaliber penetrator 3 and a sabot 4 with two flanges 5 . 6 , In this case, the rear-side flange 5 of the sabot 4 a groove-shaped recess 7 on, in which originally the now cut off slipping seal tape 8th (in 1 indicated by dashed lines) was arranged.

After knocking off the slipping seal tape 8th For example, by a chisel or a special pliers, the groove-shaped recess 7 cleaned, if necessary, and then in the 3 and 4 illustrated prefabricated new sealing tape 9 , eg made of polyamide, from the projectile nose over the sabot 4 into the groove-shaped recess 7 in the flange 5 pushed, so that in 2 shown arrangement results.

The new sealing tape 9 has a separation slot 10 to allow easy and quick installation, which has an oblique course to ensure additional security against gas penetration during firing.

After applying the new sealing tape 9 on the sabot 4 becomes the separation slot 10 be additionally sealed by a closure means, for example Elastosil.

The sealing or guide tape 9 For example, it consists of soft metal or a material which is capable of deformation. When applying the new guide bands 9 always an elastic deformation is expected or assumed. An adhesive bond between sealing tape and projectile is not necessary.
