Definitions

  • the invention relates to a warhead according to the preamble of Claim 1.
  • Plastic-bound explosives are insensitive explosives. In ammunition technology, there has been a demand for some time New developments include such plastic-bound, insensitive explosives use. Plastic-bound explosives have various advantages Disadvantage of such molded plastic-bonded explosives is that their thermal expansion coefficient compared to Thermal expansion coefficient of the explosive surrounding parts is large. If the explosive, i. the explosive charge of the warhead well on the surrounding parts, resulting from temperature changes - especially at geometrically large explosive charges - in the explosive temperature-related Residual stresses. These residual stresses can lead to cracks. Is he liable? Explosive, i. the explosive charge, on the surrounding parts not or only are slightly, especially at low temperatures due to the temperature-induced contraction of the explosive charge column between the Explosive charge and the surrounding parts hardly or unavoidable.
  • the invention is therefore based on the object, a warhead the to create the aforementioned type, with a compensation of the large Thermal expansion of the plastic-bound explosive is ensured.
  • the warhead according to the invention is temperature-compensated to compensate Dimensional changes between the one relatively large Coefficient of thermal expansion, molded plastic-bonded Explosive charge and the charge surrounding the explosive charge Compensation volume provided.
  • This can be from at least one to the Charge envelope be formed circumferential bead.
  • the at least one bead can be oriented to the outside or inward.
  • the compensating volume of at least one in the axial direction of the Cargo envelope extending bead is formed. This can be outward or after be oriented inside.
  • a warhead of the latter type are in Circumferential direction of the charge shell preferably a number of axially extending Beading equidistantly provided.
  • the beads thus allow a temperature-induced change in length of the shell.
  • At least one of the charge envelope circumferential beading will make the cargo envelope over its own thermal expansion outgoing additional change in length allows.
  • the required for this Power transmission takes place in an advantageous manner by the use of Primers reinforced adhesion forces between the explosive charge and the Cargo cover. This will also cause the formation of gaps between the Explosive charge and the cargo envelope avoided.
  • the Heat expansion forces can be caused by that of a primer increased adhesion of the explosive are transferred to the cargo envelope. Between the explosive charge and the charge shell is therefore preferably a Provided primer.
  • the compensating volume of at least one spring element defined Volumenhubes is formed.
  • the Compensation element can therefore be defined by a single spring element Volumenhubes be formed.
  • the Compensation volume of a number of spring elements defined Volumenhubes is formed, the one another - preferably equidistant - provided spaced are.
  • the at least one spring element preferably consists of a rubbery material.
  • the different extent can also by an additional inner shell with at least one circumferential or with be realized at least one axially oriented bead.
  • a Training of the warhead according to the invention is the cargo envelope in one Outer shell provided.
  • the connection of the cargo envelope to the outer shell takes place such that acting in the longitudinal or radial direction Geometry changes are possible.
  • at least one peripheral circumferential bead the Installation of the charge d.h ,. Inner shell together with a pre-stressed Rubber spring suitable volume stroke.
  • Figure 1 shows a longitudinal section of a first embodiment of the effective charge 10 with a Hollow charge explosive charge 12 made of plastic-bound, insensitive Explosive 14, which is surrounded by a cargo shell 16. Between the Explosive charge 12 and the charge shell 16, a primer 18 is provided by means of which the explosive 14 adheres to the cargo envelope 16.
  • the compensation volume 20 is 20 formed by two encircling around the cargo envelope 16 beads 22, which from each other axially spaced.
  • the circumferential beads 22 oriented radially outward.
  • the figures 3 and 4 an embodiment of the effective charge 10, in which the circumferential beads 22 radially are oriented inward.
  • the active charge 10 according to the figures 3 and 4 of the active charge according to the figures 1 and 2 similarly designed so that it unnecessary, in connection with the figures 3 and 4 all the details to describe in detail once.
  • Figures 5 and 6 show yet another embodiment of the effective charge 10, at the to compensate for temperature-related dimensional changes between the Explosive charge 12 and the surrounding charge envelope 16 provided Compensation volume 20 extending in the axial direction of the cargo envelope Beading 24 is formed.
  • the axially oriented ones are Beads 24 in the circumferential direction of the effective charge 10 from each other evenly spaced provided.
  • Primer 18 is provided between the explosive charge 12 made of plastic-bound insensitive explosive 14 and the charge shell 16 is also in this embodiment of the effective charge 10 .
  • the equidistantly spaced from each other axially oriented beads 24 may be radially outward or - as shown - radially to be oriented inward.
  • FIG. 7 shows longitudinally sectioned an active charge 10 according to FIGS. 3 and 4 circumferential, radially inwardly oriented beads 22, wherein the charge shell 16 is disposed in an outer shell 26.
  • the outer shell 26 is termein Published by the manufacturer of the product.
  • FIG. 8 shows a longitudinal sectional view similar to FIG Wirkladung 10 according to Figures 5 and 6 combined with an outer shell 26, the same details in Figure 8 with the same reference numerals as in Figure 7 are designated so that it is unnecessary, in conjunction with Figure 8 all these To describe details in detail again.
  • FIG. 9 shows longitudinally sectioned an active charge 10 with an explosive charge 12 plastic-bonded insensitive explosive 14 and a charge shell 16.
  • the cargo shell 16 is disposed in an outer shell 26.
  • the outer shell 26 is material integral with a bottom 28 is formed.
  • an igniter 30 is arranged in the center of the floor 28 .
  • a spring element 36 defined Volumenhubes provided between the floor 28 and the back End face 34 of the explosive charge 12 is a spring element 36 defined Volumenhubes provided.
  • the compensating volume 20 forming spring element 36 is formed as an annular body 38, which is the longitudinal central axis 40 of Explosive charge 12 is provided concentrically.
  • FIG. 10 shows an embodiment of the active charge 10 with an explosive charge 12 which surrounded by a cargo envelope 16.
  • the explosive charge 12 off plastic-bonded insensitive explosive 14 with the charge shell 16 is in an outer shell 26, the material integral with a bottom 28th is trained.
  • a number of spring elements 36 are provided, which along a to the longitudinal central axis 40 concentric pitch circle from each other evenly are provided spaced. While in the embodiment according to FIG. 9, the Spring element 36 is designed as a ring body are in accordance with the training Figure 10, the spring elements 36 defined Volumenhubes disc-shaped educated.
  • Recesses 42 in the at least one spring element 36 are to provided to the volume stroke of the at least one spring element 36 define.
  • the at least one spring element 36 forms between the Explosive charge 12 and the cargo envelope 16 a compensation volume 20th
