Description

Die Erfindung bezieht sich auf ein Tarnnetz zum Tarnen militäri­scher Fahrzeuge und Geräte mit einem Tragnetz und einem damit ver­knüpften Laubschnitt.The invention relates to a camouflage net for camouflaging military vehicles and devices with a support net and a leaf cut associated therewith.

Tarnnetze, wie die heutigen Kunststoff-Tarnnetze haben die Auf­gabe militärisches Gerät vor Entdeckung zu schützen. Dabei kommt es neben der optischen Anpassung an die Umgebung auch darauf an eine Tarnwirkung im infrarot-Bereich zu erzielen. Die Aufgabe ei­nes Tarnnetzes umfaßt daher eine multispektrale Anpassung an die Vegetation und die Bodenbeschaffenheit im Gelände und an den Hin­tergrund gegebenenfalls bebauter Gebiete. Außerdem wäre es wün­schenswert, wenn die Tarnnetze auch eine Tarnwirkung gegen Radar­erfassung erzielen würden, aber die bisher bekanntgewordenen Tarn­netze sind nur in der Lage eine optische Tarnung und eine Tarnung im nahen infarot-Bereich zu erzielen.Camouflage nets, like today's plastic camouflage nets, have the task of protecting military equipment from being discovered. In addition to the optical adaptation to the environment, it is also important to achieve a camouflage effect in the infrared range. The task of a camouflage network therefore includes a multispectral adaptation to the vegetation and soil conditions in the terrain and to the background of possibly built-up areas. In addition, it would be desirable if the camouflage nets also had a camouflage effect against radar detection, but the camouflage nets which have become known so far are only able to achieve optical camouflage and camouflage in the near infrared range.

Aufgabe der Erfindung ist es somit ein Tarnnetz zu schaffen, daß eine breitbandige Tarnwirkung im infarot-Bereich, im Radarbereich und im optischen Bereich besitzt und daß darüber hinaus eine Tar­nung sowohl im Gelände als auch in urbaner Umgebung bewirkt. Die­se Aufgabe ist erfindungsgemäß durch die Kennzeichenmerkmale des Anspruchs 1 gelöst.The object of the invention is therefore to provide a camouflage network that has a broadband camouflage effect in the infrared range, in the radar range and in the optical range and that also causes camouflage both in the terrain and in an urban environment. This object is achieved according to the invention by the characterizing features of claim 1.

Weiterbildungen der Erfindung sind den Ansprüchen 2-9 zu entneh­men.Further developments of the invention can be found in claims 2-9.

Das erfindungsgemäße Tragnetz ist als Doppelnetz aus zwei Kompo­nenten aufgebaut. Für das Tarnnetz wird dabei ein engmaschig ge­wirktes Netz benutzt, das entweder aus Polyester oder einem Mischgarn definierten elektrischen Widerstandes, wie z.B. Stahl­fasern, besteht. Die Maschen können dabei Größen von bis 5 mm erreichen und außerdem ist es zweckmäßig mehrere gleichmäßig ver­teilte größere Löcher im Tragnetz vorzusehen, welche zum Anknüpfen des Laubschittes dienen. Aufgrund der filigrane Struktur des Trag­netzes und der im Gewirke des Tragnetzes verteilten Fasern, z.B. Stahlfibrillen, ergibt sich ein radar- verlustbehaftetes Netz, welches eine geringe Radarreflektivität und Transmission besitzt. Das Gewirke des Tragnetzes kann auch durch inkoporierte Verlust­stoffe charakterisiert sein, die elektrisch und/oder magnetisch wirksam sind. Die zweite Komponente ist ein Polyamis- oder Polyestergewebe bzw. eine Gewebefolie, dessen Dichte durch die Anzahl der Fäden pro cm in Ketten- und Schußrichtung festgelegt ist. Das Gewebe wird mit einer Laubschnitt-Stanzung versehen und anschließend mit dem Tragnetz veknüpft. Die Oberfläche der Gewebe­folie kann genoppt oder nichtgenoppt sein.The support network according to the invention is constructed as a double network from two components. For the camouflage net, a closely knit net is used, which consists either of polyester or a mixed yarn of defined electrical resistance, such as steel fibers. The mesh can reach sizes of up to 5 mm and it is also advisable to provide several evenly distributed larger holes in the support net, which can be attached serve the leaf cut. Due to the filigree structure of the support network and the fibers distributed in the knitted fabric of the support network, for example steel fibrils, a radar lossy network results which has low radar reflectivity and transmission. The knitted fabric of the support network can also be characterized by incoporated loss substances which are electrically and / or magnetically active. The second component is a polyamis or polyester fabric or a fabric film, the density of which is determined by the number of threads per cm in the warp and weft directions. The fabric is stamped with a foliage cut and then knotted with the support net. The surface of the fabric film can be nubbed or not.

Das Gewebe für den Laubschnitt kann verlustfrei oder verlustbe­haftet sein, wobei eine verlustbehaftete Ausführung durch einge­legte elektrisch leitende Fasern oder Fasern definierter Leit­fähigkeit realisierbar ist. Es ist aber auch möglich, das Gewebe mit elektrischen und/oder magnetischen Verluststoffen zu be­schichten. Hierdurch ergibt sich die Möglichkeit verlustbehaftete Schichten aufzubauen, und zwar durch Ummanfelung leitender oder nichtleitender Fasern mit verlustbehafteter Substanz. Eine solche Gewebeart darf nur mit einer derartigen Verluststoffkonzentration beschichtet sein, daß der Primärreflex der einfallenden Welle (ge­messen am nicht gestanzten Gewebe) in seiner Intensität auf den Primärreflex des als Tragnetz dienenden Gewirkes abgestimmt ist. Damit ergibt sich eine zweistufige Tarnstruktur im Radarbereich.The tissue for the leaf cut can be lossless or lossy, a lossy design being able to be implemented by inserted electrically conductive fibers or fibers of defined conductivity. However, it is also possible to coat the fabric with electrical and / or magnetic waste materials. This results in the possibility of building up lossy layers, namely by sheathing conductive or non-conductive fibers with lossy substance. Such a type of fabric may only be coated with such a concentration of waste material that the intensity of the primary reflex of the incident wave (measured on the non-punched tissue) is matched to the primary reflex of the knitted fabric serving as a support net. This results in a two-stage camouflage structure in the radar area.

Aufgrund der Kombination von nicht geschlossenen Flächengebilden wird für die infrarot-Signatur des tarnenden Objektes eine redu­zierende Struktur geschaffen, wobei der Zwischenraum zwischen Ge­webefolie und Gewirke eine Hinterlüftung zuläßt. Hierdurch wird zusätzlich ein Wärmestau vermieden und damit eine sich auf die in­frarot-Ortbarkeit nachteilig auswirkende Erwärmung des Tarnnetzes.Due to the combination of non-closed planar structures, a reducing structure is created for the infrared signature of the camouflaging object, the space between the fabric film and the knitted fabric permitting rear ventilation. This additionally prevents heat build-up and thus heating the camouflage network, which has a disadvantageous effect on infrared locatability.

Im optischen Bereich, und zwar zur Tarnung im Gelände, dient die Flächengeometrie der Gewebestanzung. Durch besondere Formen der Stanzung ist eine Signaturreduktion möglich, welche noch durch eine besondere Farbbeschichtung gesteigert werden kann. Bei ur­banem Hintergrund kann eine Tarnung dadurch erzielt werden, wenn das Tragnetz nach außen gelegt wird. Eine besondere Färbung des Tragneztes sichert dann mit der ebenen Struktur des Gewrikes ei­ne hinreichende Tarnung bei Einsätzen in urbaner Umgebung.In the optical area, specifically for camouflage in the field, the surface geometry is used for tissue punching. A special form of punching enables a signature reduction, which can be increased by a special color coating. With an urban background, camouflage can be achieved if the support net is placed outside. A special coloring of the Tragneztes then ensures with the flat structure of the Gewrikes a sufficient camouflage when used in an urban environment.
