Definitions

  • the invention relates to a bomblet carrier projectile with practice bomblets arranged in the projectile shell according to the features specified in the preamble of claim 1.
  • the object of the invention is to design the bomblet carrier projectile and exercise bomblets to be transported therefrom in such a way that the exercise bomblet on the one hand withstands the high acceleration forces occurring during transport to the target area and on the other hand does not sink into it when it hits a resilient surface.
  • a very light exercise bomblet is created, whereby the total weight of the exercise bomblet is reduced in such a way that deep penetration into a flexible surface is avoided and the signature with detonation cloud, flash of light and bang is good is noticeable.
  • This paper-based and / or plastic-made practice bomblet housing also offers particularly advantageous absolute security against splintering, because compared to a practice bomblet housing made of, for example, die-cast, there can be no danger of splinters flying away.
  • a paper-based practice bomblet housing there is advantageously no residue left in the event of a misfire compared to a metal housing, because the practice bomblet housing rots early on, for example due to moisture.
  • bom-bomblet housing made on paper and / or plastic is subject to narrower limits than a metal case in terms of load capacity, for example in terms of compressive strength, support of the bom-bomblets according to the invention within the bomblet carrier floor allows the bom-bomblets to withstand the high initial accelerations Withstand transport to the target area and can be ejected over the target area in a manner known per se via an ejection charge from the rear of the carrier floor.
  • a layer-by-layer support of the practice bomblets within the carrier storey has proven to be an advantageous solution, as a result of which the practice bomblets located in one plane or position are supported in the projectile-axial direction.
  • the support elements consist of disc-shaped support plates arranged transversely to the projectile axis and of axial supports, as a result of which the exercise bomblets can be inserted and supported in layers in the bomblet carrier floor.
  • the arrangement of the exercise bomblets in one layer is not fixed in the circumferential direction and can therefore vary from layer to layer. This results in a simplified installation method.
  • the axial supports between the support plates ensure reliable maintenance of a support spacing in bomblet length, so that the individual practice bomblets do not have to absorb additional axial forces from practice bomblets of pre-stacked layers.
  • the axial forces resulting from this layer-by-layer stacking of bom bomblets arranged one above the other cannot therefore have a negative effect on the stability of the bomblet housing according to the invention, the load due to the initial acceleration being reduced further advantageously due to the reduced bomblet housing weight.
  • the axial supports can be arranged adjacent to the projectile shell in the carrier storey, whereby they can fill the free spaces of the exercise bomblets as fillers to save space or can be arranged between two adjacent support plates as a one-piece or multi-piece central support in the interior free space formed by the exercise bomblets.
  • This central support contains an axial gas passage channel for the ignition of all practice bomblets arranged in the carrier floor.
  • each support plate contains connecting grooves on the top side from the central gas pressure channel to the individual exercise bomblets, as a result of which these can be ignited from below without additional means.
  • the different axial supports also allow the installation of differently designed exercise bomblets.
  • the arrangement of external axial supports allows the installation of additional practice bomblets with lateral ignition, for example via lateral bomblet housing bores or an ignition cord located on the periphery of the bomblet housing. Due to the low axial bomblet load, inexpensive and easy to manufacture housing configurations are possible, which can consist, for example, of a simple cardboard tube with glued-in cardboard or plastic disks or a one-piece housing pot formed from cardboard.
  • FIG. 1 illustrates a bomblet carrier projectile 10, the housing 12 of which has a cylindrical area for receiving exercise bomblets 14, 16, 18, 20, 21 shown in more detail in FIGS. 2 to 11 and a front ogival projectile area 22 for receiving an igniter 24, one of a Ejection charge 26 and ejection plate 28 has existing ejection unit.
  • the ejection plate 28 contains a central gas passage duct 30 'through which the ejection charge 26 during the ejection process of the exercise bomblets over a target area in each bomblet 14, 16, 18, 20, 21 located ignition delay set 15, 74, 76 can be ignited.
  • the exercise bomblets 14, 16, 18, 20, 21, shown in more detail in FIGS. 2 to 11 and described in detail, can each be arranged in the bomblet carrier floor 12, each with a housing 32, 34, 36, 38, 40 made on paper and / or plastic .
  • the exercise bomblets 14 received by the bomblet carrier projectile 10 in FIG. 1 are supported in layers within the bomblet carrier projectile 10, for which purpose stackable supporting elements 42, 44, 46 (FIG. 5) are arranged in the carrier projectile envelope 12 in the projectile axial direction.
  • a support element is provided by an exercise bomb 14 located below each in the same flat position and disk-shaped support plate 42 arranged transversely to the projectile axis 11, which are supported to the adjacent support plates 42 by axial supports 44, the axial supports having a height corresponding to the bomblet length in order to form a sufficient support spacing.
  • the axial supports 44 shown in FIG. 1 lie between two adjacent support plates 42 on the projectile shell 12 and are designed as fillers filling the spaces 48 (FIG. 6) between the exercise bomblets 14. These axial supports 44 can also be used in advantageous use of a different weight described in DE 36 29 668 C1 for regulating the center of gravity of the support projectile 10.
  • the support plates 42 can, however, as shown in Figures 5 and 6, are supported by a centrally arranged axial support 46, which can be constructed in one or more pieces and on the inside forms a portion of the central gas passage 30 'and on the outside radially to the respective bomblet circumference of each of the bomblets 14, 20, 21 located in a flat position rests. Due to the above-described outside design of these axial supports 46, the advantage of a holder known from DE 38 08 898 A1 can be used for radial securing of the bomblets and for securing in the circumferential direction.
  • the latter is continued through the interior 30 formed by the bomblet arrangement and opens into a central gas passage duct 30 'in each plane bomblet layer, the disk-shaped support plate 42.
  • This disk-shaped support plate 42 contains, on the side facing the exercise bomb 14, for example, grooves 50, 52 shown in more detail in FIG. 7 for the passage of the Gas pressure and the flame to ignite all practice bomblets arranged on the support plate 42.
  • the gas initially flows from the axial gas passage channel 30 'via radially extending grooves 50 arranged in a star shape and from there via a circular groove 52 to each exercise bomb 14, whereby an ignition delay set 15, 74 arranged on the end face in the exercise bombs 14, 20, 21 76 is ignitable.
  • the exercise bomblets 14 fill a partial volume of the bomblet carrier floor 12 in a reduced number, the remaining partial volume being filled by a hollow cylinder 43 connected to the lowermost support plate 42.
  • the bomblet carrier floor 10 is further provided with a guide band 45 known per se and a floor 47 which can be released when the bomblets are ejected above the target area.
  • the bomblet housings 32, 34, 36, 38, 40 shown in detail in FIGS. 2, 3 and 8 to 11 consist entirely or at least part of the housing of cardboard.
