Definitions

  • the invention relates to a fragmentation warhead for controlling technical objectives with only one circumferential and the explosive charge surrounding fragment-forming shell, which is removable with the aid of the warhead arranged means.
  • a fragmentation warhead according to the preamble of claim 1 is known from DE 19629389C1.
  • a fragmentation warhead usually acts radially to its main axis, the achievable effect depends on the type of fragments produced.
  • FR 2685077 A1 describes a warhead in which two splinter-forming casings, which are either identically or differently pre-scored, are arranged one inside the other around the explosive charge.
  • Drive means are provided which allow a controlled movement of the two shells against each other, so that due to the displacement of the notches against each other when the charge is triggered, an adjustable size distribution of the splitter can be achieved.
  • a shift of one of the cases on the Explosive charge itself is not intended and is in the sense of the underlying task also not desired.
  • a suggestion for the reduction of performance in general and beyond also for the direction-dependent reduction in benefits is not given.
  • the particular advantage of the invention is that after the displacement or rotation of at least part of the fragment-forming shell of the warhead there eliminates the splinter effect.
  • undamaged areas of explosive charges decompose at the beginning of the reaction due to the forming gases and pressures faster and thus at least there can no longer go into a detonation.
  • the splitter power in the target direction can be increased and at the same time the remaining blast power in the collateral direction can be reduced.
  • Fig. 1 shows a simplified simplified section through the explosive charge 1 of a warhead.
  • the explosive charge is homogeneous or stratified from a known explosive and is detonatively initiated via a conventional ignition chain 2, which is executed in two stages in the embodiment and is arranged in the drawing on the right front side.
  • the explosive charge 1 is surrounded by a thin sheath 6 made of metal or plastic.
  • a circumferential splinter-forming shell 4 is provided, which can be slid or rotated by means of a drive not shown sliding on the jacket 6.
  • the shell decomposes depending on their design in the detonation of the explosive charge into smaller, medium or larger splinters, which are radially accelerated.
  • the entire charge is detonatively converted and the entire sheath 4 will become effective as a radially spreading splitter cloud.
  • the effect of the controlled power control of fragmentation according to the invention can be used.
  • the fragment-forming casing 4 is displaced completely or partially prior to initiation by the ignition chain 2. This limits the producible fragment quantity to that part of the casing 4 which directly surrounds the explosive charge 1.
  • the ignition chain 2 is directed opposite to another deflagrative ignition chain 3 on the opposite end face of the explosive charge 1.
  • a fragmentary or projectile-forming charge acting in the axial direction e.g., one or more small shaped charges
  • the portion of the explosive charge 1 which is influenced, for example, by the spike of the shaped charge 3 is mechanically disassembled or worn down only to the extent that it no longer detonatively reacts, even in the event of subsequent detonative initiation by the ignition chain 2.
  • the generated detonation or effect fronts converge towards each other and meet approximately in the middle of the explosive charge 1 in the dashed line shown 5.
  • the right part of the explosive charge 1 is implemented detonatively.
  • the left part is detonatively ineffective due to the effect of shaped charge 3.
  • the fragment-producing shell 4 can be displaced or twisted relative to the explosive charge in such a way that a proportion of the fragment-forming shell selectable between 0 and 100% becomes effective.
  • the fragment-forming casing 4 is displaced so far that only the portion of the fragment-forming casing 4 located above the detonatively converted portion of the explosive charge (on the right of the dashed line 5) remains effective.
  • the deflagrative degrading or mechanically demountable part of the explosive charge is supported here, as it can be easily removed mechanically uninsulated and also does not tend to go into a detonative implementation.
  • the displacement of the shatter-forming sheath 4 in the embodiment can at different times and by means of different drive means respectively. It is conceivable, for example, manually execute a corresponding preset before the start of the warhead carrying aircraft. During the flight to the destination, the displacement can be performed, for example, by means of a biased spring device to the desired degree of displacement. If the displacement is to be performed only near the target, it is possible to use a motor drive, in particular an electric motor or stepping motor. For very fast movement of the fragment-forming shell are pyrotechnic drives such as gas generators, propellant charges or detonatively implemented explosive charges.
  • the homogeneous charge 1 is equipped only with a detonating ignition chain 2. In extreme cases, only one sector of the shell is left over the explosive charge, whereby the fragmentation is limited to a narrow angle range.
  • the detonating detonating chain 2 is replaced by a securing device 2a.
  • ignition circuits 2 b each having its own ignition chains 2 c, consisting of a detonator and an ignition amplifier, are assigned to the partial areas of the explosive charge 1. In this way, the splitter performance increases in the target direction and it simultaneously reduces the remaining blast performance in the collateral direction.
