Description

MILITARY DECOY ELEMENTFIELD

[0001] The present invention relates to military decoy elements and military decoys.BACKGROUND

[0002] Military decoys are typically made to mimic exactly their original counterpart. With such an approach highly credible decoys can be fabricated. Unfortunately, building of required number of decoys for all different military platforms is expensive and may lead to huge storage and transport demand. As well, pre-shaped decoys can not be changed from one model to another limiting the operational usability of decoys.

[0003] One of the key aspects for the credible decoy are the right dimensions. With current approaches, dimensions can not be changed or they are limited to too rough, i.e., 1 m, dimensional accuracy. In addition, the assembly of the decoy and achieving a firm attachment between parts of the decoy can be difficult. Furthermore, it is difficult to assembly parts having larger dimensions, because it is difficult to handle the parts with hands. This may result in difficulties during the assembly of the modular decoy.

[0004] An object of the present invention is this to mitigate at least some of the above- mentioned problems.SUMMARY

[0005] An object of the present invention is to provide a military decoy, which mimic its original counterpart and has right dimensions. A further object is to provide a military decoy, which is easy to assemble.

[0007] Significant benefits are gained with aid of the present method. The decoy element enables easy connection of parts of the decoy element. The decoy element enables forming a modular military decoy, because the length of the decoy element can be freely altered. The different cross-sectional shapes and the sizes of the modules and the connector enables sliding the connector around or in the modules while keeping the formed shape reasonably firm.

[0021] In the present context, the term “military decoy” refers to an apparatus, which resemble its original counterpart used for military purposes, for example, a platform, a building, a container, a missile launcher, a tank or an artillery platform. The military decoy can be a training target.

[0022] In the present context, the term “a cross-sectional shape across an elongation dimension” refers to a cross-sectional shape of a module and a connector, when they are cut perpendicularly to the elongation dimension.

[0023] In the present context, the term “operational state” refers to a state of parts in which they are used in a decoy usage, after an assembly.

[0024] In the present context, the term “folded state” refers to a state of parts in which they are collapsed for transport, for example.

[0025] In the present context, the term “hinge” refers to a joint or mechanism, which connects objects, such as panels, and allows an angle of rotation between the objects. The hinge can be a mechanical hinge made of for example, metal or plastic. Alternatively, the hinge can be a piece of tape connecting the objects. A first portion of the tape can be attached to a first panel and the second portion of the tape can be attached to a second panel next to the first panel thus forming a hinge, which connects the panels and allows an angle of rotation between the panels. The tape can be attached to the panels during the assembly of a decoy. Alternatively, the hinge can be formed by making a fold line or a groove on one surface of a panel, along which fold line or groove the panel can be folded. The military decoy can comprise several different types of hinges.

[0026] In the present context, the expression “hingedly attached together” means that objects, such as panels, are connected together by at least one hinge as described above.

[0027] Dimensions of the present military decoys cannot be changed or they are limited to too rough, i.e., 1 m, dimensional accuracy. Dimension of the military decoy should have at least 20 cm dimensional variability. However, the military decoys made of parts having a length of 20 cm or less would be impractical. On the other hand, connecting parts having required decoy dimensions, such as 3-10 m, is difficult, because the parts are difficult to handle. It is difficult to attach the larger parts in precise and firm connection with each other by hand, which can result in a poor connection between the parts. This in further may results in difficulties during the assembly of the military decoy comprising a plurality interconnected parts. In addition, the locking of the parts is typically made to a fixed position or dimension. Thus, lengths or widths of the parts can not be changed before or during the operation of the military decoy.

[0028] According to an aspect, there is provided a military decoy element 100, comprising:- two modules 110, which are elongated along an elongation dimension and which exhibit a first cross-sectional shape of a first size across the elongation dimension, and- a connector 120, which is configured to attach the modules 110 together into alignment in the elongation dimension and which exhibits a second cross-sectional shape of a second size across the elongation dimension.

[0029] The military decoy element enables easy connection of parts of the decoy element. The different cross-sectional shapes and the sizes of the modules and the connectors enables sliding the connector around or in the modules while keeping the formed shape reasonably firm. The decoy element enables forming a modular military decoy, because the length of the decoy element can be freely altered by sliding the connector in respect to the module. The modules and the connector can be firmly locked to each other and to the required length due to the different cross-sectional shapes and the sizes of the modules and the connectors, which will ease the assembly of a modular military decoy.

[0030] The military decoy element 100 can comprise a plurality of such modules 110 including more than two modules 110 and a plurality of such connectors 120, wherein the plurality of connectors 120 is one less than the plurality of modules 110. Then, the connector120 can be placed between successive modules 110. Thus, the modules 110 and the connectors 120 can be placed one after other, i.e., to alternate, in the elongation dimension. This enables forming longer military decoy elements without increasing sizes of the modules and / or the connectors. Thus, the modules and the connectors are reasonably small and easy to handle.

[0031] The modules 110 can be arranged along the elongation dimension so that the cross-sectional shapes of the modules 110 are placed parallel in the elongation dimension. Respectively, the connectors 120 can be arranged along the elongation dimension so that the cross-sectional shapes of the connectors 120 are parallel in the elongation dimension. Thus, the cross-sectional shapes of the modules 110, and respectively the cross-sectional shapes of the connectors 120, match when viewed along the elongation dimension.

[0032] FIGURE 1 illustrates a military decoy element 100. The military decoy element 100 comprises a plurality of modules 110, namely three modules 110, and a plurality of connectors 120, namely two connectors 120, which are configured to be attached into alignment in the elongation dimension. Each of the connectors 120 are placed between the successive modules 110. Thus, the modules 110 and the connectors 120 alternate in the elongation dimension.

[0033] The length of the military decoy element 100 can be configured to be adjusted at least 1 cm, preferably at least 20 cm, in the elongation dimension.

[0034] The connector(s) 120 can be:- (a) collar(s) 121 configured to be placed around the modules 110, or- (an) inner structure(s) 122 configured to be placed inside the modules 110.The collar 121 can be placed around the modules so that it at least partially encloses the modules when viewed along the elongation dimension. The collar 121 can be placed to enclose at least the ends of the modules 110, which ends are configured to be placed facing each other, when the modules 110 are attached together into alignment in the elongation dimension. The inner structure 122 can be placed inside the modules 110 so that it is at least partially enclosed by the modules 110, when viewed along the elongation dimension. The inner structure 122 can be placed inside the modules 110 so that it extends inside the both modules 110 connected together into alignment in the elongation dimension. The inner structure 122 can be configured to support at least the ends of the modules 110, which ends are configured to be placed facing each other, when the modules 110 are attached togetherinto alignment in the elongation dimension. When the connector 120 is the collar 121, the cross-sectional size of the connector 120 is larger than the cross-sectional size of the module 110. When the connector 120 is the inner structure 122, the cross-sectional size of the connector is smaller than the cross-sectional size of the module 110.

[0035] The military decoy element can comprise both the collars 121 and the inner structures 122.

[0036] The modules 110 and the connector(s) 120 can comprise a plurality of profile panels attached together. The profile panels can be connected with each other so that they can be only constructed to produce the predetermined 3D-structure.

[0037] The first cross-sectional shape can be a rectangle.

[0038] The second cross-sectional shape can be a trapezoid. Due to the slightly conical shape, the connector will allow the ease of sliding of the connectors around or in the modules while keeping the formed shape reasonably firm.

[0039] The trapezoid can comprise a first base, a second base parallel to the first base and two legs connecting the bases, wherein a length of the first base is shorter or longer than a length of the second base. Thus, the connector can slide around or in the modules while keeping the formed shape reasonably firm.

[0040] A length of the first base can be 0.5 to 3.5 %, preferably 2 %, shorter or longer than a length of the second base. This enables a sufficient difference in lengths of the bases so that the connector can slide around or in the modules while keeping the formed shape reasonably firm.

[0041] The modules 110 and the connector(s) 120 can have widths, which extends perpendicularly to the elongation dimension. The greatest widths of the modules 110 can be smaller than the smallest widths of the connector(s) 120, when the connector(s) 120 is / are the collar(s) 121. The smallest widths of the modules 110 can be longer than the longest widths of the connector(s) 120, when the connector(s) is / are the inner structure(s) 122. Thus, the module fits inside the collar or the inner structure fits inside the module.

[0042] The connector(s) 120 can form (a) closed profile(s) around or inside the modules 110 when viewed along the elongation dimension. Thus, the profile panels of the connector(s) 120 can be connected with each other so that they can be only constructed toproduce the predetermined 3D-structure. In addition, the closed profile enables forming a rigid connection between the modules.

[0043] FIGURE 2A illustrates cross-sectional shapes and sizes of a module 110 and a connector 120, when the connector is a collar 121. The cross-sectional shape of the module 110 is a rectangle and the cross-sectional shape of the collar 121 is a trapezoid. The module 110 is enclosed by the collar 121. The collar 121 forms a closed profile around the module 110. The cross-sectional size of the collar 121 is larger than the cross-sectional size of the module 110.

[0044] FIGURE 2B illustrates cross-sectional shapes and sizes of a module 110 and a connector 120, when the connector is an inner structure 122. The cross-sectional shape of the module 110 is a rectangle and the cross-sectional shape of the inner structure 122 is a trapezoid. The inner structure 122 is enclosed by the module 110. The inner structure 122 forms a closed profile inside the module 110. The cross-sectional size of the inner structure 122 is smaller than the cross-sectional size of the module 110.

[0045] According to an embodiment:- (a) length(s) of the connector(s) 120 can be the same, shorter or longer in the elongation dimension than lengths of the modules 110, and / or- the length(s) of the connector(s) 120 can at least 0.5 times the lengths of the modules 110.Thus, the connector is sufficiently long to connect the modules firmly together and the modules stay connected when the military decoy element is moved.

[0046] Optionally, the modules 110 and the connector(s) 120 can be configured to be fastened together by quick release fasteners. The quick release fasteners secure the modules and the connector(s) firmly together. The quick release fasteners are easy to use. In addition, the modules and the connector(s) can be secured together without tools. This makes the assembly of the military decoy element more straightforward.

[0047] The military decoy element 100 can comprise one or more than one slot 130 formed to:- the connector(s) 120 when the connector(s) 120 is / are the collar(s) 121, or- the modules 110 when the connector(s) 120 is / are the inner structure(s) 122.The slot(s) 130 is / are easy to form into the connector(s) 120 or the modules 110 for example, by cutting. Each of the modules 110 and the connector(s) 110 can comprise a plurality of profile panels hingedly attached together. Then, the slots 130 can be formed into all panels of the connector(s) 120 or the module(s) 110. Each of the panels can comprise for example, one to four slots 130.

[0048] The military decoy element 100 can further comprise one or more than one fastening part 141 and one or more than counterpart 140 configured to be connected together via the slot(s) 130, which fastening part(s) 141 and counterpart(s) 140 are attached to:- the modules 110 when the connector(s) 120 is / are the collar(s) 121, or- the connector(s) 120 when the connector(s) 120 is / are the inner structure(s) 122. The fastening part 141 and the counterpart 140 can be connected together via the slot 130 so that the counterpart 140 extend through the slot 130 to the fastening part to connect with the fastening part 141. Then, a panel of the module 110 and a panel of the connector 120 settle between the fastening part 141 and the counterpart 140. Thus, the fastening part and the counterpart 140 form together a quick release fastener, which can be used to lock the military decoy element in a preferred length without tools.

[0049] Preferably, the number of the fastening parts 141 is the same than the number of the counterparts 140 and the slots 130.

[0050] The counterpart(s) 140 can be (a) pivot(s). The pivot(s) can extend through the slot 130 to the fastening part 141 to connect with it.

[0051] The slot(s) 130 can be elongated along the elongation dimension. The slot 130 can have a length in the elongation dimension and a width perpendicularly to the elongation dimension in a plane of the panel in which the slot is formed. Then, the length is greater than the width. This enables sliding the counterpart 140 in the slot 130 along the elongation dimension so that the length of the decoy element 100 can be freely altered by sliding the connector 120 in respect to the module 110. Thus, a length of the military decoy element can be controlled.

[0052] Alternatively, the slot(s) 130 can be elongated perpendicularly to the elongation dimension. The slot 130 can have a length perpendicularly to the elongation dimension and a width in the elongation dimension in a plane of the panel in which the slot is formed.

[0053] FIGURE 3 illustrates a module 110 and a connector, which is a collar 121. The collar 121 comprises a plurality of slots 130, which are elongated along the elongation dimension. The slots 130 are formed near comers of panels of the collar 121. However, the slots 130 can be arranged in other ways, such as at a distance from the comer. The module 110 comprises a plurality of fastening parts 141. The module 110 is configured to be slide inside the collar 121, as illustrated in Figure 3.

[0054] FIGURE 4 illustrates the module 110 and the collar 121 of FIGURE 3 connected together. The collar 121 is arranged around the module 110 so that the module 110 is partially enclosed by the collar 121 in the elongation dimension. The assembly further comprises a plurality of counterparts 140, which are configured to be connected with the fastening parts 141 via the slots 130.

[0055] FIGURE 5 illustrates a module 110 and a connector, which is an inner stmcturel22. The module 110 comprises a plurality of slots 130, which are elongated along the elongation dimension. The slots 130 are formed near comers of panels of the module. However, the slots 130 can be arranged in other ways, such as at a distance from the comer. The inner stmcture 122 comprises a plurality of fastening parts 141. The inner stmcture 122 is configured to be slide inside the module 110, as illustrated in Figure 5.

[0056] FIGURE 6 illustrates the module 110 and the inner stmcture 122 of FIGURE 5 connected together. The module 110 is arranged around the inner stmcture 122 so that the inner stmcture 122 is partially enclosed by the module 110 in the elongation dimension. The assembly further comprises a plurality of counter parts 140, which are configured to be connected with the fastening parts 141 via the slots 130.

[0057] The modules 110 and the connector(s) 120 can comprise a plurality of profile panels hingedly attached together. The modules 110 and the connector(s) 120 can be configured to be folded between an operational state and a folded state. Folding between the operational state and the folded state can be provided by the hinged attachments between the profile panels. The profile panels can be relatively rigid, so the folding only occurs at the hinged attachments.

[0058] The hinged attachments of the profile panels can be cuts, grooves or pull fasteners. Preferably, the cuts or grooves are used. The cuts, grooves and pull fasteners provide a simple and low-cost way to form the hinged attachments. In addition, no tools arerequired for folding the modules and the connector(s) between the operational state and folded state by the cuts, grooves and pull fasteners.

[0059] The cuts or grooves can be formed on outer surfaces of the modules 110 and the connector(s) 120. The modules 110 and the connector(s) 120 can be manufactured from plates, which comprise the cuts or grooves 150 at predetermined distances from each other and extending in the same direction. The cuts or grooves 150 can extend along the elongation dimension of the modules 110 and the connector(s) 120. The modules 110 and the connector(s) 120 can be folded by the cuts or grooves for forming the predetermined perimeters.

[0060] The cuts or grooves 150 can extend from outer surfaces of the modules 110 and the connector(s) 120 partially inside the modules 110 and the connector(s) 120. By “outer surface” is meant surfaces of the panels of the modules 110 and the connector 120, which are at least partially visible, when the military decoy element is assembled. Thus, the profile panels are formed between the cuts or grooves 150. The cuts or grooves 150 hingedly connects the profile panels together. Thus, there is no need for additional hinges.

[0061] Optionally, the modules 110 and the connector(s) 120 can comprise reinforcing elements, such as tapes, on inner surfaces of the modules 110 and the connector(s) 120 at places of the cuts or grooves 150. By “inner surface” it is meant opposite surfaces of the outer surfaces of the panels of the modules 110 and the connector 120, which surfaces are at least partially inside the modules 110 and the connector(s) 120, when the military decoy element is assembled. This reinforces the modules 110 and the connector(s) 120 at the places of the cuts or grooves 150 and prevent the profile panels for detaching from each other.

[0062] The pull fastener can connect two adjacent profile panels together. A first part of the pull fastener can be arranged on a first profile panel and a second part of the pull fastener can be arranged on an adjacent second profile panel. The first and second profile panels can be connected together by closing the pull fastener.

[0063] The modules 110 and the connector(s) 120 can comprise fold lines 160 on the inner surfaces of the profile panels. The fold lines 160 can extend in the elongation dimension. The fold lines enable folding the modules 110 and the connector(s) 120 to an even smaller package. Thus, the modules 110 and the connector(s) 120 are easier to handle by hands and transport.

[0064] The modules 110 and the connector(s) 120 can comprise the fold lines 160 on the inner surfaces of two opposite panels of the closed perimeter. Thus, the fold lines are formed symmetrically on the closed perimeter, which enables easier folding of the panels to the folded state.

[0065] The fold lines 160 can be configured to connect two portions of the profile panel together so that outer surfaces of the two portions are configured to be folded facing each other. Then, the module 110 or the connector(s) 120 comprising four profile panels can be folded to the folded state so that it takes up space only the area of one panel. Thus, the fold lines enable folding the modules or the connector(s) to an even smaller package.

[0066] The fold lines 160 can be cuts, grooves or pull fasteners. Preferably, the cuts or grooves are used. The cuts, grooves and pull fasteners provide a simple and low-cost way to form the fold lines. In addition, no tools are required for folding the profiles between the operational state and folded state by the cuts, grooves and pull fasteners.

[0067] The cuts or grooves of the fold lines 160 can be formed on the inner surfaces of the panels. The cuts or grooves of the fold lines 160 can be arranged at predetermined distances from each other and extending in the same direction.

[0068] The cuts or grooves of the fold lines 160 can extend from the inner surfaces of the modules 110 and the connector(s) 120 partially inside the modules 110 and the connector(s) 120. Thus, the cuts or grooves of the fold lines 160 hingedly connects two portions of the profile panels together. Thus, there is no need for additional hinges.

[0069] Optionally, the modules 110 and / or the connector(s) 120 can comprise a reinforcing element, such a tape, on an inner surface of the modules 110 and / or the connector(s) 120 at a place of the cut or groove of the fold line 160. This reinforces the profile at the place of the cut or groove, and prevent the profile panels for detaching from each other.

[0070] The pull fastener of the fold line 160 can connect two parts of a profile panel together. A first part of the pull fastener can be arranged on a first part of the profile panel and a second part of the pull fastener can be arranged on a second part of the profile panel. The first part and second part can be connected together by closing the pull fastener.

[0071] The connector(s) 120, which is / are the inner structure(s) 122, can comprise an inner structure panel(s) 127 arranged inside the closed perimeter in a plane extending along the elongation dimension. This makes the inner structure rigid and thus prevents it for collapsing.

[0072] FIGURE 7 illustrates a collar 121 in a folded state, during erecting and in an operational state. The collar 121 comprises a plurality of panels, namely four panels. The panels are hingedly attached together by cuts 150, which are configured to extend in the elongation dimension, when the military decoy element is assembled. The collar 121 further comprises fold lines 160, which are configured to extend in the elongation dimension, when the military decoy element is assembled. The fold lines 160 are cuts, which are formed on inner surfaces of two opposite panels of the closed perimeter. The fold lines 160 divides the panels in two portions. In the folded state, the two portions are folded facing each other. During erecting, the folding is opened. In the operational state, the portions of the panel extend in the same plane and form a side panel of the collar 121.

[0073] FIGURE 8 illustrates an inner structure 122 in a folded state and an operation state. The inner structure 122 comprises a plurality of panels, namely five panels. In the folded state, a first panel 123 and a second panel 124 are hingedly attached together by a cut 150. Respectively, a third panel 125 and a fourth panel 126 are hingedly attached together by a cut 150. The second panel 124 and the third panel 125 are hingedly connected together via an inner structure panel 127. In the operational state, the first panel 123 and the third panel 125 are connected together. In addition, the second panel 124 and the fourth panel 126 are connected together. The inner structure panel 127 is inside the closed perimeter formed by the first, second, third and fourth panel 123, 124, 125, 126 and in a plane, which is configured to extend along the elongation dimension, when the military decoy element is assembled.

[0074] The profile panels and the inner structure panels can be manufactured from lightweight but rigid material, for example, corrugated plastic or foam board, such as polyurethane or KAPA®. A thickness of the corrugated plastic can be for example, 3-10 mm, preferably about 5 mm, so that they can be folded to transport package and opened to form the required parts of the elements.

[0075] The military decoy element 100 can further comprise a camouflage material cover on an outer surface. The camouflage material can be, but is not limited to, a paint, afabric, a textile, a fibre-based product, or a fibre reinforced composite or a laminate, which is configured to be placed on the military decoy element after assembling it. The camouflage material helps the military decoy element to blend in with its surroundings. On the other hand, it makes the military decoy element credible even for close range observation.

[0076] The military decoy element 100 can further comprise a plurality of thermal elements, such as an add-on foil or an electronic decal, for thermal signature control. The thermal elements can be connected directly on the military decoy element, they can be separate elements, or they can be integrated with the camouflage material. The thermal elements can be passive or active in which case they can be controlled individually or in groups containing at least two thermal elements. The passive element can be for example, a coating or an added component having different thermal emissivity than its surrounding. The active element can be for example, a resistive heater or a Peltier element. The thermal elements are used to provide an authentic thermal signature for the decoy element.

[0077] The military decoy element 100 can further comprise a plurality of near infrared (NIR) and short-wave infrared (SWIR) bands reflective or emitting elements.

[0078] The military decoy element 100 can further comprise a plurality of radar bands reflective or absorbing elements. The plurality of elements can reflect or absorb the radar bands at 1 GHz-20 GHz. The radar bands reflective element can be for example, an electrically conductive paint, a coating or aluminum foil. The radar bands reflective element makes the military decoy element visible with radar imaging. The radar bands absorbing element can be for example, a radar absorbing paint, coating or a foil or a semi-transparent, at radar band, coating placed for example A / 4 apart of underlying surface. The radar bands absorbing elements decrease the radar cross-section area of the military decoy element and can be used to increase the authenticity of the military decoy element.
