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 preferably insulated with a film, for. B. formed as a sieve tube gas-permeable tube into which a particulate, preferably platelet-shaped propellant charge is filled.
  • the geometry of the openings of the gas-permeable tube is matched to the propellant charge in order to obtain the desired clamping, ie the desired ratio of the total areas of all openings of the gas-permeable tube to its 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 which is a mixture of an oxygen-releasing compound, such as potassium or ammonium perchlorate, and a metal powder, such as aluminum powder, optionally with additives, such as a plastic particle ignition mixture intended.
  • an oxygen-releasing compound such as potassium or ammonium perchlorate
  • a metal powder such as aluminum powder
  • additives such as a plastic particle ignition mixture intended.
  • Appropriate coordination of these components not only controls the ignition and function of the gas generator, but also the effect of the ejection device in relation to the outflow behavior of the ammunition in particular Container.
  • cluster munitions 3 are located in the shell 2 of a warhead 1.
  • 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 in which the cluster munitions 3 are located.
  • the two end faces of the bellows 4 are covered by bulkhead plates, which does not appear from the drawing.
  • 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 ignition cords 10, 10 'can for. B. by a so-called “Hivelite” cord ("Hivelite” is a registered trademark), which is formed by a metal tube in which an ignition mixture of cesium borohydride, potassium nitrate as an oxidizing agent and a polyethylene glycol binder is contained.
  • Hivelite is a registered trademark
  • a particle ignition mixture 11 is arranged around the ignition cords 10, 10 ′, i. H. an ignition mixture that generates a particle-rich hot gas when it burns.
  • the particle ignition mixture 11 can e.g. B. from a mixture of an oxygen-donating compound, such as potassium nitrate, and a metal powder, for. B. boron or aluminum powder.
  • the particle ignition mixture 11 is surrounded by a tubular film 13, preferably a shrink tube.
  • the propellant charge 12 consisting of platelets is located in the annular space between the particle ignition mixture 11 or the tubular film 13 and the tube 8 or the insulating film 9.
  • the tubular film 13 prevents the particle ignition mixture 11 with the propellant charge 12 from being inoperable Condition of the device mixed and causes a targeted, z. B. uniform distribution of the particle ignition mixture 11 around the ignition cords 10, 10 '.
  • the propellant charge 12 consists, for. B. from a double-base fuel.
  • pyrotechnic delay elements 14 are integrated in the ignition cords 10, 10 10, which can be initiated by an amplifier charge, not shown.
  • the delay elements 14 are in a housing which opens into a pipe 15 via a spout 16. It can be seen that the ignition cords 10, 10 ⁇ , the particle ignition mixture 11 and the tubular film 13 form a unit. This unit is connected to the tube 15 via the film tube 13.
  • 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.
  • 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 ignition cords 10, 10 ⁇ lead to the burning of the particle ignition mixture 11. The tubular particle ignition mixture 11 is destroyed by the burning particle ignition mixture 11, whereby the hot particles of the ignition mixture 11 are pressed between the platelets of the propellant charge 12 and 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. Accordingly, the hot particles of the ignition cord 10, 10 'not only have the task of igniting the propellant charge 12, 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 type of insulation and the type and quantity of the ignition cords 10, 10 ' can be determined by the type, quantity and axial distribution of the fuel and the configuration of the propellant charge 12 and its axial distribution respectively.
  • the propellant charge 12 into individual segments or annular chambers 21 by axially spaced apart, radially extending partition walls 20 made of inert material between the tubular film 13 and the tube 9.
  • the partitions 20 can, for. B. consist of plastic or 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.
