Definitions

  • the present invention relates to a contact head for high-speed smoke launchers.
  • Rapid smoke throwing bodies are fired from shot cups, so-called launchers, to e.g. to build up a smoke screen in front of a vehicle to be camouflaged.
  • the vehicle has several launcher, from which several smoke projectors are deployed simultaneously.
  • Such smoke projectors are e.g. described in DE 35 10 367 A 1 and EU 0157421 A 3.
  • the smoke towers When fired, the smoke towers rest with their firing heads on thorns arranged centrally in the launcher.
  • the main difficulty to be overcome is that the smoke towers fly at exactly the same distance, since this is the only way to form a rapidly closing smoke screen by simultaneously igniting the fog set.
  • the task is solved with a contact head for quick mist launchers with external contact rings that can be fired from launchers, a bridge igniter, propellant charge and delay set connected to them, in which the contact head has outflow channels arranged centrally around a central opening, which remain free when lying on the spike of the launcher.
  • the throwing range scatter can be significantly reduced with the help of the outflow channels arranged as above.
  • the quick mist throwing bodies lie with the ignition head on the upper flattened portion of the launcher's mandrel, the central opening being dimensioned somewhat smaller than the flattened portion.
  • the outflow channels remain free, so that the outflowing gas formed by the ignition of the propellant charge can wash around the mandrel, even if the central opening is still covered by the flattening.
  • the shape of the channels can be slots or notches arranged around the central opening or else radially arranged webs, which in turn rest on the flattening of the launcher mandrel.
  • An improvement in the ignition pulse for the propellant charge can be achieved according to the invention if additional firing is interposed between the propellant charge or the bridge igniter and the delay charge.
  • the lighting is preferably made of black powder and is secured with a gauze to the bridge igniter and the propellant charge.
  • a simple construction of the ignition head according to the invention is that the bridge igniter and propellant charge are accommodated in one insert and the firing and delay set in a counterpart, which are connected to one another by a screw-on crown with an opening.
  • the insert has exhaust gas holes directed towards the central opening in the ignition head, from which the propellant gases exit into the outflow channels.
  • the bridge igniter can be connected to the contact rings by means of vertically supplied cables in such a way that the cables are guided through the contact head via a centrally arranged bore and laterally around the insert and are softly soldered to the contact rings.
  • the propellant charge can advantageously consist of materials such as nitrocellulose or nitroglycerin in a manner known per se.
  • the degassing holes must be dimensioned accordingly so that the pressure does not decrease too quickly.
  • the propellant consists of nitroglycerin processed into films.
  • this is advantageous from a manufacturing point of view, on the other hand, the pressure-time behavior is highly reproducible, which also benefits the improvement of the width accuracy.
  • the film is rolled into layers and placed in a chamber provided for this purpose, the film thickness being approximately 0.6-0.7 mm. A ratio of approximately 1.7 g (rolled up into three layers) of nitroglycerin foil to approximately 2 kg of thrown body has proven particularly useful.
  • the structure of the propellant charge in use can advantageously be such that the propellant charge is surrounded by a sleeve on which a sieve lies, which covers the propellant charge and which is held at a distance from the exhaust gas holes by a ring.
  • the insert is to be provided with silicone seals at all locations accessible from outside for humidity
  • the cables are e.g. sealed by casting with epoxy resin
  • insert and counterpart can be equipped with flat silicone washers, each of which has flat sealing surfaces.
  • the counterpart can also (if necessary additionally) be equipped with an O-ring seal located in an annular groove.
  • An ignition head 3 is shown with a radial collar, to which the cup (not shown) carrying the mist set is connected.
  • the contact head 3 is surrounded by a plastic ring into which the contact rings 22 are vulcanized.
  • In the top middle there is a central opening 27, which is surrounded by four notches 14, each at a right angle to one another.
  • An insert 4 is screwed into a corresponding recess and bears against the face of a perforated disc 9 and a silicone seal 12.
  • a counterpart 2 is inserted into the insert 4 and held by a screwed-on crown 5.
  • the counterpart 2 is shorter than the insert 4, whereby a chamber is formed inside which receives the propellant charge 15 and the bridge igniter 1.
  • the propellant charge consists of rolled-up nitroglycerin foil and is surrounded by a sleeve 6 of equal length. On the sleeve 6 is a sieve 8, which in turn is held at a distance via a ring 7 to the bottom of the insert.
  • the insert base has off-center exhaust gas bores 25 and an approximately sized central one through which the connecting cables of the bridge igniter 1 are guided.
  • the cables are sealed with an epoxy resin adhesive 17; the cables are routed around the insert to the contact rings 22.
  • Bridge igniter 1 propellant charge 15 and sleeve 6 lie on a gauze 21, under which the firing 18 is located and which is held by it.
  • the firing lies in a (cylindrical) recess, from which (here two) bores 19 extend downwards, which are connected to a bores 20 lying transversely thereto, and are open to the delay set 24.
  • the crown 5 has a central opening 26 which is sealed with a lead tin foil 13.
  • the insert has a radial ring groove in which an O-ring lies.
  • the desired fog walls are created much faster and more homogeneously in front of the objects to be camouflaged.
