Definitions
- the invention relates to an active body according to the preamble of patent claim 1.
- Active bodies for the protection of military objects for example aircraft from infrared-guided missiles, are sufficiently known.
- these are pyrotechnically generated heat sources which emit hot radiation.
- An infrared target is disclosed in DE 40 07 811 C2. This has a spectral distribution of the IR radiation of only very moderately warm targets.
- zeolite powder is used, which is suitable for absorbing atmospheric moisture. It can be used as a coating on a body or as a finely divided cloud of powder particles floating in the air. In principle, all zeolite types or powders with zeolite-like crystal structures are suitable.
- the fire charge consists in one embodiment of an intimate mixture of potassium nitrate and metallic boron.
- the fire rate is applied with the aid of a nitrocellulose binder on a metal foil.
- DE 42 44 682 A1 discloses a high-intensity pyrotechnic infrared flare torch. This serves to deflect a projectile which is approaching an aircraft.
- the dousing torch has a section of compact bubble-free pressed separate pieces of gas-releasing high-intensity infrared-emitting pyrotechnic compositions contained in a rupturable airtight container.
- infrared decoy target for a helicopter is also described in GB 2 327 116 A. From US Pat. No. 5,343,794 a further infrared target is known. Possible material compositions Such decoys can be found in US 6,675,716 and US 5,435,224 and US 5,343,794. Pyrotechnic fog sets are described in WO 00/58237 A1 and WO 00/58238.
- DE 196 05 337 C2 describes a method for modifying the spatial and temporal infrared structure of an aircraft on account of the new generation of infrared guided missiles with built-in flare protection circuits.
- the proposal is to artificially alter the spatial infrared signature of an aircraft not only in a narrow spatial area on the fuselage, but over typical flight dimensions.
- Another method for providing a dummy target body is DE 42 38 038 C1 removable. This is distinguished by the fact that the active masses simulating the dummy target body are brought into the position of the dummy target body to be generated in such a way and decomposed there that a spectral-spatial target signature of the object is generated for a homing head.
- the object of the invention is to create an active body which has an effective IR decoy target, for example for aircraft, an object-like spectral radiation signature with high radiation content in the area of the plasma irradiation against modern Kli ⁇ at the beginning of the ignition over the entire duration of action, a has a specific blooming process with steep rising edges and a sufficiently long action time. Furthermore, the efficacy should also be given at high altitudes with low oxygen and no performance losses at high ejection speeds (due to flow effects).
- the invention is based on the idea of providing an active body with structures having at least one active mass block of monobasic or polybasic high-energy materials on the surface. Depending on the pattern (structure) and depth, this requires an enlargement of the surface, as a result of which the burning rate of the active mass block and thus the duration of action of the active body can be controlled.
- the active mass block preferably has one or more channels / cavities in the interior, as a result of which an inward-protected initiation of the active mass block in the interior is made possible.
- the active body effective mass block
- metallic cover plates and protective foils it is thus ensured that losses of the IR radiation at high flow velocities, such as occur when the active body (effective mass block) is ejected from the aircraft, are avoided.
- gas and temperature bridges are of further advantage. These can be created by slots, perforations and / or holes between the inner channels. By a selectable number, size and arrangement of these bridges and the remaining wall thickness a defined timing of the overflamming on the outer surfaces is possible.
- the specific blooming behavior is preferably set by filling the channels with, for example, finely structured material of the same substance but with respect to the active mass block significantly increased surface / mass ratio.
- the steepness of the rising edge can be increased with increasing surface / mass ratio.
- the igniting of the active compositions is carried out in a preferred embodiment within the channels in the active mass block by preferably pyrotechnic ignition charges.
- a spontaneous, flow-dependent ignition is ensured and, on the other hand, an interference radiation originating from the ignition charge is prevented.
- FIG. 1 shows an active mass block which has two structures on its surface, for example in the form of grooves.
- the active mass block 1 has inside one or more channels / cavities 3 and filled therein effective mass substances 4.
- This Substance may be a finely structured material of the same substance but compared to the Wirkmas ⁇ senblock 1 significantly increased surface / mass ratio.
- materials with a high radiation fraction in the wavelength range are preferably between 4.1 and 4.6 ⁇ m, for example a nitrocellulose mixture with about 60% nitroglycerin and 40% diethylene glycol dinitrate.
- These active substance substances 4 can be present in the form of rods (about 0.2 to 3 mm in diameter), flakes, platelets or granules and can thus be used.
- the active mass block 1 further comprises a flow protection 5, which is formed here from a cover or protective cap 5a and a protective film 5b.
- 6 designates gas and temperature bridges, which are formed by slots, perforations or bores.
- a pyrotechnic ignition charge 7 is provided, which is preferably formed by powdered boron / potassium nitrate (proportions about 50% boron / 50% potassium nitrate).
- This primer 7 can be used in a particle size of about 0.2 to 3 mm.
