Definitions

  • the invention relates to a smoke throwing body with an active charge a pyrotechnic active material for generating one in the infrared emissive and visually impenetrable aerosols.
  • Armored and unarmored vehicles are used by Aerosol curtains against detection, detection and tracking and thus protected against the threat of missiles.
  • DE 199 14 097 A1 is a suitable pyrotechnic active material for generating a highly emissive in the infrared and in the visual impenetrable aerosol described.
  • This active mass developed a camouflage fog, in addition to the impenetrability in the visible Range also a long-lasting coverage in the infrared range allows.
  • This active material contains red as the main components Phosphorus, an alkali metal nitrate or a mixture of Alkali metal nitrates and as minor components at least one Transition metal or a metallic compound or alloy the same, at least one metalloid and a binder.
  • DE 29 08 217 C2 is a unit charge for nebulization of Vehicle described which a filled with fog bodies sleeve having.
  • the mists are cylindrical in shape on top of each other flat slices with open center hole.
  • the Mist bodies are ejected without wrapping from the sleeve.
  • a Crossfading of the line of sight in the infrared range is not provided.
  • the object of the invention is to provide a simple structure
  • a smoke-throwing body that is designed to Output in a solid angle to a quick crossfade of the Line of sight in the infrared radiation range and in the visual Radiation area comes.
  • the existing of the hollow cylinder segments effective charge stack is ejected from the shroud ejected from a launcher tube, giving aerodynamic stability in the initial phase of the flight is guaranteed. This prevents the stack already immediately unfolds at the vehicle. Only after a few meters, For example, 5 m to 10 m, break the lighted Hollow cylinder segments on the envelope. By now missing Aerodynamic fairing attacks the inflated air in the stack the hollow cylinder segments. This will make the segments immediate dislocated, resulting in a large-scale diversification of the burning hollow cylinder segments leads in a wide solid angle.
  • a smoke-impact body 1 consists of a hollow-cylindrical active charge 2, an ignition charge 3 and an envelope 4 (see Fig. 1).
  • the Wirkladung 2 is a stack of a variety of layers 5 of Hollow cylinder segments 6. Each layer 5 is made up of several Hollow cylinder segments 6 assembled. Inside the Wirkladungsstapels consists of a cavity. 7
  • each layer is 5 of four hollow cylinder segments 6 formed, wherein the segment angle a is 90 °, wherein the individual Hollow cylinder segments 6 abut.
  • the segment angle a can also be less than 90 °, then correspondingly more Hollow cylinder segments 6 are in one position.
  • the diameter d of the cavity 7 is ⁇ 1/6 D, where D is the Outer diameter of the active charge stack is (see Fig. 1, Fig. 2a, 2b).
  • the active charge stack 2 has a height H which is, for example, ⁇ 20 h, where h is the height of a hollow cylinder segment (see Figures 1, 2b, 3b).
  • the height h is preferably ⁇ 1/15 D.
  • the hollow cylinder segments 6 are made of a pyrotechnic active mass upset, which dampens one in the infrared radiation range and emissive as well as produce in the visual impenetrable aerosol.
  • a pyrotechnic active mass upset which dampens one in the infrared radiation range and emissive as well as produce in the visual impenetrable aerosol.
  • Such an active mass is described in DE 199 14 097 A1.
  • she has as main components red phosphorus, an alkali metal nitrate or a mixture of alkali metal nitrates and as minor components at least one transition metal, or a metal-rich compound or alloy thereof and at least one metalloid and a Binder on.
  • the envelope 4 has a combustible film 8, for example made of paper impregnated with paraffin.
  • the foil 8 stops initially consisting of the hollow cylinder segments 6 Wirkladungsstapel 2 together.
  • the film 8 envelops the Wirkladungsstapel 2 at the top and at its diameter D corresponding circumference U in the entire height H.
  • Figure 5 shows the Unwrapped film 8.
  • the film 8 is connected to a disc 9, the the bottom of the active charge 2 is applied.
  • the disc 9 is made of a press fiber material and has a central opening 10 on.
  • the diameter d1 of the Aperture 10 is ⁇ the diameter d (see Fig. 1, Fig. 4).
  • FIG. 6 shows the arrangement in FIG exploded state.
  • an electric ignition element 13 is arranged, the electrical Contacts 14 via a corresponding Wegrung of the vehicle are unlockable.
  • the ignition element 13 ignites upon initiation the Anzündladung 3, which can act as a discharge charge at the same time.
  • the hollow cylinder segments 6 lit and the smoke throwing body 1 is ejected.
  • the hollow cylinder segments 6 of the film. 8 held together.
  • the development of the protective mist N takes place, for example within 0.25 s after the vehicle F is threatened by the Missile K1 and K2 has been detected and evaluated.
  • Figure 8 shows a comparison of known action times and by the impact length achievable according to the invention.
  • t0 To the Time t0 is the threat of a vehicle F recognized flying missile and thus an ejection of the Nebulizer triggered, which then takes place at time t1.
  • t4 is the time at which after calculation of the vehicle F the threatening missile strikes.
