Definitions

  • the invention relates to a projectile for representing an infrared surface detector according to the preamble of the main claim.
  • a projectile is known from DE-PS 28 11 016.
  • missiles are used to set up so-called infrared dummy targets, i.e. to deflect missiles equipped with an infrared seeker. If, for example, the location devices of a ship determine that such a missile is approaching, then the missile is fired; which then ignites and ejects the burnt papers at a predetermined distance and height from the ship, so that the burnt papers form a slowly sinking, burning disturbing cloud which directs the incoming missile away from the ship and towards itself.
  • the radiation hole mentioned can lead to a reduction in protection, because the distance between the aircraft and the radiation cloud increases extremely quickly.
  • the radiation hole mentioned has a disadvantageous effect on the protection of very large and slowly moving objects, such as ships of considerable size, if for a completely different reason than in the case of the aircraft mentioned above.
  • a very early detection of the approaching missile is necessary, on the one hand because the maneuvering speed of such ships is low, and on the other hand because the missile can only be deflected if both the ship and the neighboring interference cloud are in its search field appears, which is only the case if the missile is still far away from the ship.
  • the requirement of comparatively early formation of the radiation cloud means that the radiation time of the cloud must be long, so that the burning leaves have a burning time of, for example, 30 to 40 seconds.
  • the object of the present invention is therefore to improve the throwing body of the type mentioned at the outset in such a way that the explained radiation hole of the resulting radiation cloud is considerably shortened, both in the case of combustion layers short as well as long and very long burning times for burning layers.
  • the solution to this problem results from the characteristics of the characterizing part of the main claim.
  • an ignition aid mass is switched on between the igniter charge or igniter sleeve and the burning leaves, that is to say a fast-reacting mass which, on the one hand, emits high-intensity infrared radiation during its combustion and thus, so to speak, extends the flash of the igniter charge, and on the other hand extends the layer of fire Firing leaves ignited so extensively that their radiation rising edge becomes very steep.
  • the prolongation of the radiation flash has an effect on burning papers with burning layers of any reaction speed (fast, medium, slow) with regard to the largest possible ignition, and this also in the case of a high relative speed between the burning papers and the ambient air - (prevention of the blow-out effect).
  • the dummy target shines with the highest possible intensity immediately after initiating the fault measures, because in such a case the seeker has already switched to the target and therefore the dummy target must radiate much more than the actual one Aim to pull the seeker head away from the latter.
  • This radiation behavior is in turn made possible by a mixture of fast-burning papers (high radiation intensity) and slow-burning (low radiation intensity) papers.
  • the figure shows a contact head 1 with a charge chamber in which, in the ready-to-operate state, there is an ejection charge 15, in which a squib 17 is embedded.
  • the charge chamber is closed on the bottom part of the contact head 1 with a screw cap, which has window-like predetermined breaking points and a web-shaped abutment for a spacer of a shooting cup.
  • An ignition delay set 31 is arranged in the head part of the contact head 1 and connects the charge chamber to the inside of a throwing agent container 3.
  • the ignition delay set 31 is screwed into the head part of the contact head 1 via a threaded sleeve.
  • the fastening plate 71 is arranged in a tightly closing manner in the bottom of the throwing agent container 3 via an O-ring 113.
  • the contact head 1 is made together with the screw cap, including its other components, by injection molding from polystyrene.
  • the wall thickness of the throwing agent container 3 and the material thickness of the lid 5 are approximately 0.25 mm.
  • An ignition disassembly unit 33 is inserted in the interior of the throwing agent container 3 in the mounting plate 71.
  • This ignition disassembly unit 33 consists of a sleeve 75 which contains an ignition disassembly charge 35 and which has an inwardly flanged edge 77 at its end located in the mounting plate 71 a cover disk 79 engages, via which the sleeve 75 by means of a perforated screw 81 and an annular seal 115 closes tightly in the mounting plate 71 on the bottom 29 of the litter tel thinkingers 3 is attached.
  • the bore in the cover disk 79 is covered with a glued-on film 119, preferably a tin film, and this thereby closes the ignition disassembly kit 35 with respect to the ignition delay set 31.
  • the igniter disassembly passes through an igniter core 37 made of nitrocellulose powder tubes over its entire length.
  • This powder tube preferably has a diameter of 1.3 mm and a continuous inner hole of 0.2 mm in diameter.
  • a throwing agent 73 is arranged in the interior of the throwing agent container 3, which is circular sector-shaped leaflets 83 with burning layers.
  • These circular sector-shaped leaflets 83 are thus arranged in the interior of the throwing agent container 3 at a distance around the sleeve 75 of the ignition disassembly unit 33 in a layered manner.
  • the sleeve 75 of the dog dismantling unit 33 is made of aluminum just like the throwing agent container 3 and its cover 5 and its fastening plate 71.
  • Sleeve 75, throwing agent container 3 and lid 5 each have a wall thickness of approximately 0.25 mm.
  • a second sleeve 84 which has an extremely thin wall thickness, is provided between the igniter sleeve 75 and the fuel discs 83, to be precise after these.
  • the annular space between the two sleeves 75 and 84 is filled with an ignition aid compound 85, specifically with loosely poured red phosphorus.
  • the operating sequence of this litter k örpers corresponds to that of the known throwing body, with the exception that this ignited during the ignition of the Anzündzerlegersatzes 35, the igniter mass 85 which emits considerable during their brief burn-infrared radiation strength and at the same time the internal leaflets 83 over a large area ignites.
  • This large-area ignition of the burning discs 83 results from the fact that the firing of the ignition aid mass 85 forms a fireball around the throwing body, which the burning discs 83 fly through.
  • the burning sheets 83 therefore quickly catch fire over a large area and this also when the burning layer is very slow to react, that is to say, for example, passivated or covered with a passivation layer.
  • the ignition disassembly set reacts uniformly over its entire length, so that the ignition aid can be effective evenly all around and over the entire length.
  • the ignition core made of nitrocellulose powder, which is centrally located in the ignition disassembly kit, which has a stabilizing effect with regard to rapid combustion due to its easy flammability, the high rate of combustion and the release of gas during combustion.
  • this burn-off stabilizer there could be a risk of fluctuations in the reaction speed which can be caused in the course of storage as a result of an uneven compression of the batch, these uneven compressions being caused, for example, by shaking during transport.
  • the invention is not limited to the exemplary embodiment shown, but numerous modifications are possible compared to it.
  • the second sleeve 84 is not absolutely necessary; the. Ignition aid mass 83 can also be filled into the annular space between the sleeve 75 and the stack of fuel sheets.
  • Another possibility is to extend the fuel discs 83 to the sleeve 75 and thus to drop the annular space, in which case the discs themselves are dusted with the ignition aid compound 83 or this is applied to the discs as the top layer.
  • an ignition aid compound other than red phosphorus but this is preferred because it is usually also part of the burning layer of the leaflets 83.
