Definitions

  • the present invention relates to signal stars, as are used in particular in parachute cartridges.
  • the signal stars can also be used with other signal cartridges.
  • parachute cartridges or light cartridges are fired from civilian or military use from guns and burn z. B. from the so-called apron lighting on the parachute in a predetermined time.
  • conventional ammunitions In order to make the burn-up sufficiently long or to prevent the signal star from burning too quickly, conventional ammunitions have the following structure.
  • the actual star consists of a pressed light set, which is surrounded by a jacket in an aluminum sleeve and housed in a signal carrier.
  • the star itself rests on an exhaust charge, under which the deceleration rate and propellant rate are arranged.
  • the latter can be surrounded by a tail unit and are located in a cartridge case with propellant charge before firing.
  • the sheath mentioned usually consists, for. B. made of paper, aluminum or PVC and dampens the burning rate of the star.
  • Disadvantages are, among other things, a relatively high loss of luminosity due to the sheathing and, at the same time, a narrowly conical burn-off image, which makes detection more difficult from unfavorable angles.
  • the burnup is not residue-free, ie hot slag or metal parts can fall to the floor and lead to injuries or fires.
  • the object of the present invention is therefore to improve signal stars in such a way that their light output is increased significantly, that hot residues are largely avoided and that the burn-up image is enlarged.
  • the light output of conventional stars (yellow) is around 40,000 to 45,000 cd.
  • a signal star for light signals in particular with a diameter of 22 mm and a minimum burning time of 12 seconds, consisting of a pressed light set, in which, according to the invention, the light set is preferably fired from a 26.5 mm pistol, preferably on a parachute sinks to the ground, the burning time and the construction are dimensioned such that the light set burned out before it touched the ground, the light intensity was at least 90,000 cd. and the parachute is not damaged by heat.
  • the light set has, in particular, a coating either of a lacquer layer which is applied to the signal star or of a layer of film or paper provided with an adhesive layer which is glued to the light set.
  • the varnish coating provides an ideal seal of air humidity during storage.
  • the paints should contain pigment, preferably in an amount of 20-80% by volume.
  • Alkyd resin lacquer, chlorinated rubber lacquer, epoxy resin lacquer, acrylate resin lacquer, oil lacquer, nitro lacquer, polyester lacquer, polyurethane lacquer and the so-called combination lacquers are mainly proposed.
  • the present invention therefore proposes a different procedure for the production thereof, in order to achieve a reproducible predetermined burn-up on the one hand and on the other hand to improve its manageability for painting.
  • the signal stars according to the invention consist of a compressed granulate.
  • the latter is obtained in a simple manner by mixing and kneading the set with a binder. After subsequent granulation, pressable products are obtained.
  • the pressure must be much higher than conventional and about 20 to 40 tons with usual dimensions.
  • the signal stars produced in this way are extremely stable and free of cracks. Their combustion behavior is homogeneous, they are particularly suitable for attaching the casing in the manner described above.
  • An extension of the burning time can also be achieved in a simple manner by adding inert mineral substances, such as in particular metal oxides, as moderators to the light set. Silicon and titanium oxides have proven particularly useful for this purpose.
  • the mineral substances can be added in amounts of 3-6% by weight, an increase in 6% mineral material resulting in an increase in the burning time of approximately 30%.
  • the light sets according to the invention are used in parachute cartridges. This causes the parachute lines to burn in about 4% of the cases.
  • a barrier layer of non-combustible oxides preferably of sodium nitrate, in the area of the suspension of the screen.
  • suspensions and the barrier layer can be incorporated during the pressing or casting process.
  • An effective additional protection of the parachute lines is further achieved according to the invention in that metal threads or glass fiber fabric is spun into the parachute lines or that these consist entirely of them.
  • a so-called stocko cap is inserted into the parachute before it is pressed, through which a split pin is guided and spread.
  • a metal perforated disc between the stock cap and the cotter pin, on which the entire set is filled and pressed. After removal from the mold, the perforated disc forms the star closure towards the parachute.
  • the light set has the following recipe: Sodium nitrate + 1% linseed oil 37% by weight Polyolefin 3% by weight Magnesium 60% by weight
  • the polyolefin is e.g. B. a U.S.I. Chemicals manufactured and sold under the name Microthene.
  • This light set was made with a binder from polychlorobutadiene 11.5% by weight and a dilution of 6.6% by weight mixed, where as polychlorobutadiene z.
  • B. a product known under the trade name "Macroplast" can be used.
  • the star consists of a set 1 pressed from granulate as described above, as well as the intermediate set 2 and the firing 3. It is covered at the bottom with an aluminum ring 4, which can also be pressed.
  • the star On the head side, the star has the perforated disk 5 made of Al Cu Mg alloy, through which the cotter pin 6 extends. Below the perforated disc 5, the stock cap 7 is held by the split pin 6.
  • the perforated disc 5 is covered with a cardboard disc 8.
  • a coating of paint with a thickness of about 0.1 mm is designated, which was given around the pressed set by painting. This coating excludes the ingress of oxygen during combustion as well as the ingress of moisture during storage.
  • the signal carrier is connected to a tail unit 18 by means of bevels, the ejection charge 19 for the star being accommodated in the bevels.
  • a deceleration charge 20 and a propellant charge 21 are located below the exhaust charge 19.
  • the tail unit itself is located in a cartridge case (not shown) with propellant charge and primer prior to completion.
