Definitions

  • the invention relates to a device for ejecting containers, in particular ammunition, from a warhead or similar container according to the preamble of claim 1.
  • the invention as characterized in the claims, is based on the object of making the outlet behavior of the containers to be ejected easy to vary within wide limits.
  • the gas generator thus consists of a z. B. designed as a sieve tube gas-permeable tube, in which a particulate, preferably platelet-shaped propellant charge is preferably filled from a double-base fuel to get gas-permeable pipe to the outer surface.
  • the propellant charge is ignited by at least one pyrotechnic ignition cord, which lies in the central axis of the gas-permeable tube and extends over the entire length of the gas generator tube and which is a mixture of an oxygen-releasing compound, such as potassium or ammonium chlorate, and a metal powder, such as aluminum powder, if appropriate with additives such as a plastic binder has, that is a mixture that corresponds approximately to a composite propellant.
  • So-called ITLX (Ignition Thin Layer X-Cord) ignition cords are particularly preferred.
  • a bellows 4 is provided, which is arranged concentrically to the longitudinal axis 5 of the warhead 1.
  • the Bellows 4 has concave pockets 6, which are directed towards the longitudinal axis 5 and contain the cluster munitions 3.
  • the two end faces of the bellows 4 are covered by bulkhead plates, which does not appear from the drawing.
  • the bellows 4 When the bellows 4 is pressurized from the inside, it deforms into a cylinder, ie the pockets 6 are turned outwards at high speed and the cluster munitions 3 are ejected in the process. Sattvier z. B. three pockets 6 may also be provided.
  • the bellows 4 is pressurized by the gas generator 7.
  • the gas generator 7 consists of a sieve tube 8 which is arranged concentrically to the longitudinal axis 5 and is insulated on its inner wall with a polyethylene film 9.
  • Two ignition cords 10, 10 ⁇ extend in the middle of the tube 8 along the entire longitudinal axis 5.
  • the igniter cords 10, 10 ⁇ are formed by ITLX igniter cords.
  • such an ignition cord consists of a hose 11 made of an inner hose layer 30 made of plastic, for. B. polyethylene, a reinforcing layer 31 made of a fiber mesh, for. B. glass fibers, and a plastic outer jacket 32, z. B. made of polyethylene.
  • three strands 33 are arranged, which are formed from a mixture of potassium perchlorate, ammonium perchlorate and aluminum powder, bound with polyethylene acrylate.
  • Such an ignition cord has a high propagation speed with a hot, particle-rich flame, the flame front propagating in the strands 33 leading to a disassembly of the hose 11.
  • the propellant charge 12 consisting of platelets is located in the space between the ignition cords 10, 10 ⁇ and the gas generator 8 which is insulated with the insulating foil 9.
  • the propellant charge 12 consists, for. B. from a double-base fuel.
  • 3 pyrotechnic delay elements 14 are integrated in the ignition cords 10, 10 ⁇ , which can be initiated by an amplifier charge, not shown.
  • the sieve tube 8 is closed at both ends by closure parts 18, 18 29.
  • closure part 18 ⁇ the other end of the ignition cords 10, 10 ⁇ with z. B. adhesive 17 attached.
  • 10 ⁇ inert bodies, z. B. in the form of plastic foam rings 19, 19 ⁇ provided in any axial distribution, for. B. between the propellant charge 12 and the delay element 14 and at the other end of the tube 8th
  • the warhead shell 2 is first z. B. eliminated by cutting cords, not shown. Thereupon, the ignition cords 10, 10 An are ignited, delayed by the delay element 14.
  • the ITLX igniter cords 10, 10 ⁇ lead to the formation of a hot particle-rich flame. The hot particles are pressed between the platelets of the propellant charge 12 to ignite them. In this way, the propellant charge 12 is ignited simultaneously over the entire length with a correspondingly rapid and controllable pressure build-up.
  • the insulation or the film 9 is necessary because a sufficiently high pressure or a sufficiently high temperature are required to ignite the propellant charge 12.
  • opening the dam 9 leads to a sudden drop in pressure.
  • the hot particles of the ITLX ignition cord 10, 10 ⁇ accordingly not only have the task of causing the propellant charge 12 to be ignited, but also prevent the propellant charge 12 from extinguishing as a result of the pressure drop after the dam 9 is opened.
  • An essential advantage of the device according to the invention is that the departure acceleration or generally the departure behavior of the cluster munitions can be adapted relatively easily to the respective requirements and can be varied over the length of the bellows.
  • the propellant charge 12 into individual segments or annular chambers 21 by axially spaced apart, radially extending partition walls 20 made of inter material between the ignition cords 10, 10 ⁇ and the tube 9.
  • the partitions 20 can, for. B. consist of plastic foam rings.
  • bellows 4 separated by bulkhead plates can be arranged one behind the other along the tube 8, each of which is equipped with cluster ammunition.
  • B. is controllable by the amount of propellant charge provided for each bellows 4 in the gas generator 7, z. B. but also by further in the firing cords 10, 10schn integrated pyrotechnic delay elements, either the resulting entire firing units with the corresponding type, amount and distribution of the propellant charge 12 in a single tube 8 z.
  • B. separated by partitions or bulkheads or several separate complete gas generators 7 can be arranged in a row in the warhead longitudinal axis 5 in a row.
