Definitions

  • the invention relates to a stack of ammunition bodies according to the preamble of patent claim 1.
  • Such a stack of ammunition bodies is known from DE-A-26 07 336.
  • the stack of ammunition bodies is enclosed in a carrier projectile and the holding parts holding the ammunition bodies together consist of half-shells forming the projectile jacket.
  • the half-shells are held together on the lower part of the floor by two folding tail wings, which are connected to the floor by hinges.
  • An ejection charge is present in the projectile tip above the ammunition body stack, which is ignited after the projectile emerges from the launch tube and blows off the projectile tip including the igniter.
  • the folding tail wings and half shells can then fold outwards, are braked by the air flow and release the stack of ammunition bodies, the individual ammunition bodies flying away in the direction of flight.
  • This device uses, in a known manner, a complete projectile for receiving the stack of ammunition bodies.
  • the projectile with the ammunition body stack thus consists in the complex manufacturing process of a complete jacket consisting of two half-shells with the two-part folding tail unit, the projectile tip and the projectile floor with the hinges.
  • EP-A-0 130 893 discloses a stack of ammunition bodies of the type mentioned at the outset.
  • An artillery projectile is described there, which consists of a nose element, a central body and a base element.
  • the central body contains the ammunition body stack, which is held together by straps.
  • the bands are guided around ejectable holding pins at the front end of the central body and held by these.
  • the ligaments are attached with pins.
  • the invention has for its object to form a stack of ammunition body of the type mentioned so that it forms the projectile itself with only a few other holding parts.
  • Fig. 1 shows a cannon 1 when shooting ammunition stacks with different distribution patterns of ammunition bodies.
  • the term ammunition stack is used instead of ammunition body stack for the sake of simplicity.
  • the beams 2a and 2b show firing paths from five ammunition bodies arranged one behind the other in an ammunition stack, with an immediate and with a delayed opening of the ammunition stack.
  • Fig. 1b shows a top view of an elliptically irregular distribution of the ammunition 3 after firing from the tube 4 of the cannon 1 with immediate and delayed opening of the ammunition stack according to the trajectories 2a and 2b.
  • FIGS. 1c and 1d represent a straight line-shaped and a scattered line-shaped distribution of the ammunition bodies 3.
  • the stacks of ammunition can be fired with a similar effect from launch tubes in aircraft or from submunition containers attached to aircraft with launch tubes.
  • ammunition stacks with three ammunition bodies 3 are always shown for the sake of simplicity.
  • the number of ammunition bodies 3 arranged one behind the other in an ammunition stack is arbitrary and depends only on the type and use of the ammunition bodies.
  • 2 and 3 represent a stack of ammunition 5 with which three munitions 3 lying one against the other can be ejected in the direction of an arrow 6, for example from the launch tube 4 of the cannon 1.
  • the ammunition body 3 are held together by four resilient flat strips 7.
  • Two flat belts 7 are connected to each other on the head side of the ammunition stack 5 by a cross belt 8.
  • the flat strips 7 with hooks 9 grip over the last ammunition body 3, being pressed against the ammunition body 3 with a tensioning means in the form of a band or soft wire 10 placed over the hooks 9.
  • the flat strips 7 can serve as slide rails in the launch tube 4 with a suitable surface treatment, for example with a lubricious plastic.
  • the clamping means 10 burns or melts due to the propellant gases during firing, so that the flat strips 7 according to FIG. 3 can expand immediately after leaving the firing tube.
  • the ammunition stack 5 follows the trajectory 2a of FIG. 1a and ammunition bodies 3 have the elliptical distribution on the bottom according to FIG. 1b.
  • the three ammunition bodies 3 on the head and bottom are additionally held together by end plates 16 and 17 by the flat strips 7.
  • the tensioning means drawn by the hook 9 here consists of a solid wire 18 which is additionally guided through a separating device 19.
  • the separating device has, in a known, not shown manner, a cutting knife for cutting the wire 18 inside. The cutting knife is released after leaving the firing tube by releasing a spring 20, whereby in this arrangement, as in the case of the ammunition stack 5 of FIG. 2 , the ammunition stack 15 follows the trajectory 2a of FIG. 1a and the ammunition bodies 3 on the floor have the elliptical distribution according to FIG. 1b.
  • FIG. 5 shows an ammunition stack 25 which, in addition to end disks 16 and 17, also has intermediate disks 26 and in which the ammunition bodies 3 are held together by only two flat strips 7.
  • a separating device 27 is provided here, which contains a delay set in the interior in a known manner, which is ignited by the propellant gases and melts a wire 28 serving as tensioning means for the flat strips 7 after a predetermined delay time, whereby the flat strips 7 open resiliently and the Release ammunition 3.
  • the ammunition stack 3 thus follows the trajectory 2b of FIG. 1a and the ammunition bodies 3 also have an elliptical distribution on the bottom according to FIG. 1.
  • the second and third ammunition bodies can be released with a delay compared to the previous one.
  • hook elements 29 are provided behind the intermediate disks in FIG. 6, which engage in the intermediate disks 26. This prevents the flat band 7 from spreading out completely immediately. Only when the first base-side ammunition body 3 is pulled out by the air forces due to the partial spreading of the flat strips 7 after loosening the hooks 9, can the first intermediate disk 26 be released from the hook element 29 and the flat strips 7 can be separated from one another Spread out the intermediate disc 26, whereby the second ammunition body 3 is released, etc. An almost linear distribution pattern corresponding to FIG. 1c can thereby be achieved. 7, the intermediate disk 26 is additionally supported by a driver 30, in which the hook element 29 engages.
  • FIG. 9 shows a top view of a parachute cap 44, one quarter of which is provided with an airtight fabric surface 45 and three quarters with open ring surfaces 46.
  • FIG. 10 shows the bottom part of an ammunition stack 50, in which the ammunition bodies 3 are ejected with a sabot 51.
  • the sabot 51 has a sealing part 52 acted upon by the propellant gases and a part 53 attached thereto, in which a separating device 54 is mounted.
  • the separating device 54 has a sleeve 55 in which a piston 57 loaded with a spring 56 is displaceably mounted.
  • a band 58 serving as a tensioning means is pulled through the sleeve 55 and the piston 57.
  • the spring 56 drives out the piston 57, the band 58 being cut by a cutting edge 59, so that the flat band 7 can release the first ammunition body 3.
  • Such a sabot 51 can also be installed in the place of the sabot 38 shown in FIG. 8 in the ammunition stack 35.
