Definitions

  • the invention relates to a device for temperature control or setting of programmable detonators with a loaded cartridge according to the features of the preamble of claim 1 and to an ammunition for use in the temperature control device.
  • Adjustment devices for the temperature control of cartridges located in the weapon barrel with programmable detonators are known per se.
  • a control signal from the firing line (tank gunner) for the detonator in the cartridge (multi-purpose igniter MTA) is usually fed in via wire line via a direct electrical central contact in the base of the cartridge from a fixed contact arranged at a corresponding point in the breech of the weapon. This can disadvantageously lead to contact difficulties due to powder vapor deposits or the like.
  • the igniter setting takes place, for. B. by means of optical or electronic transmitting and receiving devices.
  • a setting pulse transmission arrangement via microwave field in the gun barrel is known, wherein the detonator arranged in the top of the projectile has a corresponding antenna and in the mouth region of the gun barrel a microwave transmitter connected to an input device is provided.
  • the transmitter unit opening into the tube must be designed to be very robust and pressure-resistant, it requires complex feeding of the microwave cables and coupling elements on the weapon barrel and, of course, must be converted or exchanged with each tube change.
  • a method and a device for setting a projectile detonator is also known, in which a transmission unit (coil or Light guide) is integrated in the area of the projectile body located in the tube and the projectile itself has a ring-shaped (electrical or optical) reception system in the central region on the circumference.
  • the transmitter unit arranged in the tube is also exposed to high pressure and high temperature and is subject to uncontrollable contamination by erosion, deposits, etc.
  • the input device consists of a transmitter unit for detonator programming pulses arranged in the area of the breech block in the protected interior of the turret, this transmitter unit can be easily checked and, if necessary, exchanged; it is not subject to extreme temperature and pressure loads like previously known transmission devices.
  • Newer types of explosive ammunition for tank cannons require the fastest possible reaction time from setting the associated detonator to breaking the shot. This requirement can only be met by setting / programming the igniter when the cartridge is already in the cargo area. This can be realized very advantageously with the igniter setting device according to the invention.
  • Deactivating an already set detonator and unloading deactivated ammunition from the weapon barrel is also ensured in the simplest and most secure manner.
  • the data transmission system according to the invention is based on the simple use of a free space between the wedge lock and the rear weapon barrel - this location or a corresponding "window” is already present in the Leopard II main battle tank, other armored weapons can also be easily operated with such a "window” be provided - within the protected turret area, where direct access to the cartridge is possible when the weapon is closed.
  • the edge of the metallic sleeve collar or sleeve bottom (stub sleeve) of the cartridge with partially combustible sleeve is freely visible from above and below.
  • This free space or free line of sight is used in the invention as a data transmission line for the ignition setting.
  • the data receiving part (antenna) is advantageously not located directly in the cargo space or front weapon barrel loaded with gas pressure and powder vapor, but on the rear collar of the projectile sleeve, which, for. B. is designed as a metallic stub and has a rubber sealing ring at its front connecting edge to a front combustible part of the cartridge case.
  • the receiving unit is protected from gas pressure and powder vapor by the metal sleeve (eyelet) with a sealing ring.
  • the data transmission system according to the invention remains unaffected.
  • the reference number 10 is the sleeve bottom of a heatable cartridge, z. B. an explosive device with an integrated programmable time fuse.
  • the cartridge is in the cargo space of an armored weapon with a caliber of e.g. B. 120 mm.
  • a wedge 14 in the breech housing 16 fixes the cartridge in the cargo space of the barrel 12.
  • the reference number 18 denotes the core axis of the weapon barrel 12 in the horizontal normal position.
  • the vertical direction range of the weapon barrel 12 around the cradle axis 24 is indicated by the upper dashed position 20 of the core axis with the weapon barrel lowered and the lower position 22 with a steep inclination of the weapon barrel.
  • Above the closure 16 is a piece of the tower roof 26 of an armored vehicle, for.
  • a wireless data transmission path is located between the turret roof 26 and the breech 14, 16 on the rear weapon barrel 12 31 for irradiation of energy and information for temperature control or setting of a programmable timer in the charged state of the cartridge.
  • a transmitter unit 28 is arranged on the tower roof 26; opposite to it is a receiving antenna 30, which is arranged in the side of the sleeve bottom 10 or sleeve collar of the metallic stub sleeve of a partially combustible cartridge case of ammunition.
  • a gap or a recess 32 (“window”) is already present between the breech housing 16 and the wedge 14 at the top and bottom, by design; in the case of other weapon carriers, such a recess can be easily retrofitted at a suitable location.
  • the energy and data transmission can e.g. B. by infrared waves, microwaves, optically visible light pulses or electromagnetic waves as pulse carriers.
  • Transmitter and receiver units are known per se, but not the arrangement of these components according to the invention.
  • the rear weapon area is shown somewhat enlarged in FIG.
  • a firing contact 34 for firing the ammunition is indicated in the locking wedge 14.
  • the transmitter unit 28 'on the upper closure housing 16 is fixed. This shortens the data transmission path 31; this requires a flexible electrical lead to the transmitter unit 28 '.
  • FIG. 2 also shows the third possibility according to the invention of arranging the transmitting unit 28 ⁇ directly against the lower recess 32 between the locking wedge 14 and the locking housing 16 in a cradle-proof manner by means of a holding arm 36.
  • the holding arm is attached to the cradle of the weapon in a manner not shown. In this case, only the elevation movements of the weapon are carried out by the cradle-fixed arrangement of the transmission unit 28 ⁇ , but not the forward and return movement of the weapon barrel.
  • FIG 3 the detail X from Figure 1 or Figure 2 is shown enlarged.
  • a recess 32 or a “window” or space remains free at the top and bottom, in which the rear region of the sleeve base 10 is visually visible.
  • the receiving antenna 30, which is connected to the programmable detonator arranged in the floor, is arranged in the edge or sleeve collar 38.
  • the receiving antenna 30 according to the invention is designed with an insulation 40 in the sleeve collar 38 as a circular antenna.
  • the receiving antenna according to the invention is designed as a punctiform antenna 30 ⁇ arranged in the sleeve collar 38 and limited in the circumferential direction or as a strip-shaped antenna 30 '. It is then necessary for the corresponding cartridge to reach the weapon in an index position via a defined loading, which always ensures that the receiving antenna 30 'or 30' of the transmitting unit 28, 28 'or 28' is opposite and the data transmission path 31, 31 'is erected.
