Definitions
- the invention relates to a smoke impact body with an active charge made of a pyrotechnic active mass for producing an aerosol that emits in the infrared and is impenetrable in the visual.
- Armored and unarmored vehicles are protected against detection, detection and target tracking using aerosol curtains and thus against the threat of missiles.
- DE 199 14 097 AI describes a suitable pyro-technical active substance for producing an aerosol which is highly emissive in the infrared and impenetrable in the visual.
- This active mass develops a camouflage mist that, in addition to being impenetrable in the visible range, also enables long-lasting coverage in the infrared range.
- the main constituents of this active mass are red phosphorus, an alkali metal nitrate or a mixture of Alkali metal nitrates and as secondary components at least one transition metal or a metallic compound or alloy thereof, at least one metalloid and a binder.
- threatening missiles fly at speeds of 200 to 600 m / s, they must be misted very quickly after they are detected.
- Known throwing bodies only develop their effect after a flight time and a time delay of, for example, 2 s. The vehicle is unprotected during this time.
- DE 29 08 217 C2 describes a unit charge for fogging vehicles, which has a sleeve filled with fog bodies.
- the mist bodies have the shape of cylindrical flat discs lying on top of one another with an open center hole.
- the mist bodies are ejected from the sleeve without being covered. A cross-fading of the line of sight in the infrared range is not provided.
- the object of the invention is to propose a simply constructed throwing body which is designed in such a way that when ejecting i ⁇ a solid angle there is a rapid cross-fading of the line of sight in the infrared radiation range and in the visual radiation range.
- the winding charge stack consisting of the hollow cylinder segments is held by the sheath and ejected from a launcher tube, which ensures aerodynamic stability in the initial phase of the flight. This prevents the stack from unfolding directly on the vehicle. Only after a few meters of flight, for example 5 m to 10 m, do the ignited hollow cylinder segments break up the envelope. Due to the lack of aerodynamic cladding, the incoming air reaches into the stack of hollow cylinder segments. As a result, the segments are immediately dispersed, which leads to a large-scale fanning out of the burning hollow cylinder segments in a wide solid angle.
- an aerosol mist distribution is created very quickly, for example within 0.25 s, which covers the vehicle both in the infrared radiation range and in the visual radiation range against missiles approaching horizontally and in gliding flight.
- the vehicle has a long period of time available in order to avoid the time of impact of the approaching missile calculated in the vehicle by driving maneuvers.
- FIG. 1 shows a smoke ejection body with several layers of hollow cylinder segments in an envelope
- FIG. 2b shows a side view in the direction of the arrows IIb-IIb in FIG. 2a
- FIG. 3a shows a single hollow cylinder segment in supervision
- FIG. 3b shows a single hollow cylinder segment in a perspective view
- FIG. 4 shows a perforated disk of the casing
- FIG. 5 a film of the wrapping, unwound
- FIG. 6 shows the smoke ejection body in an ejection device
- FIG. 7 shows an aerosol mist generated by the smoke ejection body
- FIG. 8 shows a time diagram of the development of the aerosol mist.
- a smoke ejection body 1 consists of a hollow cylindrical active charge 2, an ignition charge 3 and an envelope 4 (cf. FIG. 1).
- the active charge 2 is a stack of a plurality of layers 5 of hollow cylinder segments 6.
- Each layer 5 is composed of a plurality of hollow cylinder segments 6; there is a cavity 7 in the interior of the active charge stack.
- each layer 5 is formed by four hollow cylinder segments 6, the segment angle a being 90 °, the individual hollow cylinder segments 6 abutting one another.
- the segment angle a can also be smaller than 90 °, in which case there are correspondingly more hollow cylinder segments 6 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 (cf. FIGS. 1, 2a, 2b).
- the winding charge stack 2 has a height H which is, for example,> 20 h, where h is the height of a hollow cylinder segment (cf. FIGS. 1, 2b, 3b).
- the height h is preferably> 1/15 D.
- the hollow cylinder segments 6 are compressed from a pyrotechnic heat mass, which produce an aerosol which dampens and emits in the infrared radiation range and is impenetrable in the visual field.
- a pyrotechnic heat mass which produce an aerosol which dampens and emits in the infrared radiation range and is impenetrable in the visual field.
- Such an active mass is described in DE 199 14 097 AI. It has red phosphorus, an alkali metal nitrate or a mixture of alkali metal nitrates as the main constituents and at least one transition metal or a metal-rich compound or alloy thereof and at least one metalloid and a binder as secondary constituents.
- the ignition charge 3, which is used to ignite the hollow cylinder segments 6 via the cavity 7 and can serve as an ejection charge, is a pyrotechnic ignition charge which contains 50 to 80 percent by mass of black powder, 0 to 20% of an organic binder,
- a metal powder from the group of metals, magnesium, aluminum, boron, zirconium, titanium and 0 to 20% of a combustion moderator based on a transition metal compound, such as CuO, K [Fe 2 (CN) 6 ], (C 5 H 5 ) 2 Fe).
- the wrapper 4 has a consumable film 8, which consists, for example, of a paper soaked in paraffin.
- the film 8 holds initially the active charge stack 2 consisting of the hollow cylinder segments 6 together.
- the film 8 envelops the Wixkladungs pile 2 on the top and on its circumference U corresponding to the diameter D in the entire height H.
- FIG. 5 shows the film 8 unwound.
- the film 8 is connected to a disc 9 which rests on the underside of the active charge 2.
- the disk 9 consists of a press fiber material and has a central opening 10.
- the diameter dl of the opening 10 is> the diameter d (cf. FIG. 1, FIG. 4).
- the described smoke ejection body can be inserted into a metallic ejector tube 11 (cf. FIG. 6).
- Figure 6 shows the arrangement in an exploded state.
- an electrical ignition element 13 At the bottom 12 of the ejector tube 11 there is an electrical ignition element 13, the electrical contacts 14 of which can be unlocked via a corresponding switching device of the vehicle.
- the ignition element 13 ignites the ignition charge 3 upon initiation, which can also act as an exhaust charge.
- the hollow cylinder segments 6 are ignited and the smoke nozzle 1 is ejected.
- the hollow cylinder segments 6 remain held together by the film 8 in the range between about 5 to 10 m after the start of the gas evolution of the discharge.
- the active charge stack 2 fuses, separating the hollow cylinder segments 6, and the individual hollow cylinder segments 6 develop after a distance S at a distance from the one to be protected Vehicle F has a fog curtain N, which shields the vehicle F from both missiles K1 threatening in gliding flight and missiles K2 attacking in horizontal flight (cf. FIG. 7).
- the protective nebula N is developed, for example, within 0.25 s after the vehicle F has recognized and evaluated the threat posed by the missiles K1 and K2.
- FIG. 8 shows a comparison of known action times and the action time achievable by the projectile according to the invention.
- t4 is the point in time at which the threatening missile strikes after the calculation of the vehicle F.
- the fog development W counteracting the threat is reached along line a at time t3, whereas the level of effectiveness achieved with the device described is already reached in line b at time t2. It shows that the time period between t3 and r4 is significantly shorter than the time period between t2 and t4. This means that between t2 and t4 in the threatened vehicle there is a significantly longer time available for avoiding driving maneuvers than between the prior art, for avoiding driving maneuvers
