[0031] The present invention provides a repair assembly comprising a component, preferably an aircraft component, and the aforementioned quick-repair patch, wherein the component has a cover layer and a lightning strike surface protection portion located beneath the cover layer, as well as a partial and mechanically unrelated damaged portion, wherein the quick-repair patch covers the damaged portion and is connected to the component material by means of a fastening layer, wherein a plastic foil layer is connected to the cover layer material and faces away from the damaged portion, and wherein a conductive lightning protection layer is disposed between the plastic foil layer and the lightning strike surface protection portion.
[0032] Preferably, the lightning protection layer is electrically connected to the lightning strike surface protection part.
[0033] The present invention provides an aircraft comprising the above-mentioned quick repair patch and / or the above-mentioned repair components, wherein preferably, the components are selected from high-lift devices, flaps, canards, control surfaces, elevators, rudders, ailerons, fuselage components, rotor blades, wing surfaces, engine nacelles, horizontal tail and / or vertical tail.
[0034] This invention provides a rapid repair method for repairing localized and mechanically unrelated damage to components, preferably aircraft components, comprising a covering layer and a lightning strike surface protection layer located beneath the covering layer, wherein the method includes:
[0035] 1. A connection surface for quick repair of the patch is manufactured on the component, and the lightning strike surface protection portion is exposed if necessary;
[0036] 2. Position the aforementioned quick-repair patch at the damaged area; and
[0037] 3. The quick-repair patch is fastened to the connection surface manufactured in step 1 by pressing, thereby connecting the plastic foil layer to the cover material in a mating manner.
[0038] Preferably, the bonding surface and / or the lightning strike protection portion are manufactured by grinding in step 1.
[0039] Preferably, in step 1, the manufacturing process includes cleaning, drying, and / or degreasing the surface areas of the component to provide a connection surface.

[0041] Preferably, in step 3, the lightning protection layer makes conductive contact with the lightning strike surface protection part.
[0042] The present invention provides the use of the above-mentioned rapid repair patch for repairing localized and mechanically unrelated damaged parts of aircraft components.
[0043] Using the concept described herein, the typical lifespan of a quick repair can be increased to approximately two months. This extends the time until a full repair is required according to the repair manual. By adjusting the plastic foil accordingly, the patch can be fitted to the area to be repaired, making the overall quick repair less noticeable.
[0044] Military aircraft typically have coatings that reduce their radar signature. These coatings, known as hotspots, can be avoided by using quick-repair patches.
[0045] The smart quick surface repair patch (SQSRpatch) proposed here is a multi-layer patch with predefined dimensions and generally has three to four layers.
[0046] Layer 1 is a plastic foil layer. This layer can be colored. The plastic foil layer is, for example, polyurethane foil. The plastic foil can contain markings as information devices, such as in the form of QR codes or RFID tags. Various information about the patch or quick repair (e.g., type, manufacturing date, installation date, and individual identification number) can be stored in the information device. Optionally, the plastic foil layer can contain a reinforcement section made of reinforcing fibers (e.g., fiberglass, Kevlar). These reinforcing fibers are particularly suitable for repairing fuel tanks or combat damage. Optionally, the plastic foil can also have properties that improve camouflage (e.g., substances that absorb or attenuate suitable radar radiation). A colorless overlay can also be applied.
[0047] Layer 2 contains a conductive material. Examples of conductive materials include metal foil, perforated metal foil, extended metal mesh, and graphene. This layer serves as a lightning strike surface protection (LSSP) or electromagnetic interference shielding. Depending on the material, an additional adhesive layer may be provided between Layer 1 and Layer 2 as a connecting layer.
[0048] Layer 3 is, for example, a fastening layer made of an adhesive film. This layer may be applied only to layer 1. This layer may also be additionally disposed on layer 2, wherein a conductive adhesive is preferably used for this purpose.
[0049] In addition, a structure called Layer 1 can be arranged on Layer 1. + The layer can be optionally designed as a reinforcing layer with reinforcing fibers, a camouflage layer with improved camouflage materials, or an electrostatic discharge protection layer. This layer can also be referred to as a functional layer.
[0050] The order of these layers can be adapted to the corresponding application. The shaping of the patch can also be adapted to different situations. Therefore, patches can be designed as squares, rectangles, circles, or ellipses. The same applies to the shape of layer 2. The shape of layer 2 can differ from the overall shape.
[0051] Advantageously, a method similar to HST can be used to place the quick-repair patch. The patch is designed to better prevent peeling. Unlike HST, the patch is watertight, thus improving corrosion resistance. Even if markings or markings on the aircraft are damaged, they can be repaired at a lower cost.
[0052] Compared to HST, patches allow maintenance of minor damage to be postponed until a scheduled D-Check. In individual cases, patches may even be permitted as permanent repairs.
[0053] Correspondingly, the concept presented here allows operators to perform simpler, more durable, and safer repairs to surface damage. The repair patch provides long-lasting protection, reducing, mitigating, or even preventing surface damage associated with lightning strikes. Attached Figure Description
[0054] The embodiments are illustrated in more detail with the aid of schematic drawings. In the drawings:

[0058] Figure 4 It shows having Figure 2 Examples of repair components for rapid repair patches; and
[0059] Figure 5 An example of a patch strip is shown. Detailed Implementation
[0060] First refer to Figure 1 The figure shows an aircraft 10. The aircraft 10 includes a fuselage 12 in a manner known per se, on which a pair of wings 14 are arranged. A vertical tail 16 and a horizontal tail 18 are arranged at the rear of the fuselage 12. Each wing 14 includes a wing surface 20 and a high-lift device 22. Furthermore, the wings 14, the vertical tail 16, and the horizontal tail 18 all have control surfaces 24.
[0061] The aforementioned component 26 may have, for example, a localized and mechanically unrelated damaged portion 28 caused by a lightning strike. Component 26 includes a substrate 30. The substrate 30 may be made of metal or fiber-reinforced plastic. Furthermore, component 26 includes a lightning strike surface protection portion 32. The lightning strike surface protection portion 32 may also be formed by the substrate 30 itself. Additionally, component 26 includes a covering layer 34 disposed on the lightning strike surface protection portion 32.
[0062] Figures 2 to 4 The quick-repair patch 36 is schematically shown, which can be integrated into the repair assembly 37. Figure 4 ) is used to repair damaged parts 28. The thickness of the quick repair patch is approximately 0.1mm to 0.2mm.
[0063] The quick-repair patch 36 includes a layer structure 38. The layer structure 38 has a plastic foil layer 40. The plastic foil layer 40 is preferably made of polyurethane foil. The plastic foil layer 40 may be colored. The plastic foil layer 40 is designed herein to be rectangular. However, the plastic foil layer 40 may also have other shapes, such as circular, elliptical, or square.
[0064] Layer structure 38 includes a conductive lightning protection layer 42 disposed on one side of the plastic foil layer 40. The lightning protection layer 42 comprises a conductive material made of metal or graphene. Accordingly, the lightning protection layer 42 may include stretched metal, perforated metal foil, etc. Here, the lightning protection layer 42 is elliptical. However, the lightning protection layer 42 may also have other shapes, such as circular, rectangular, or square. The lightning protection layer 42 has a smaller area than the plastic foil layer 40. (Viewed in top view...) Figure 3 The plastic foil layer 40 has an edge region 44 disposed between the outline of the plastic foil layer 40 and the lightning protection layer 42.
[0065] A thin connecting layer 46 is arranged along the thickness direction between the plastic foil layer 40 and the lightning protection layer 42, which connects the two layers together.
[0066] Furthermore, the layer structure 38 includes a fastening layer 48 disposed on the plastic foil layer 40. The fastening layer 48 contains an adhesive to securely bond the quick-repair patch 36 to the component 26 material. In a variant, the fastening layer 48 may be bonded to the component 26 material by welding. Preferably, the fastening layer 48 is applied only to or disposed at the edge region 44. Additionally, the fastening layer 48 may also be applied to the lightning protection layer 42. In the region of the lightning protection layer 42, the adhesive is preferably designed to be conductive. Alternatively, a region of the lightning protection layer 42 may be exposed to allow electrical contact between the lightning protection layer 42 and the lightning strike surface protection portion 32.
[0067] In addition, the layer structure 38 may have a functional layer 50. The functional layer 50 is disposed on the surface of the plastic foil layer 40 facing away from the lightning protection layer 42.
[0068] The functional layer 50 may have a reinforcing layer 52 containing reinforcing fibers. Glass fiber or Kevlar may be used as the reinforcing fibers.
[0069] Functional layer 50 may have camouflage layer 54, which contains one or more radar absorption or attenuation additives.
[0070] The functional layer 50 may include an electrostatic discharge protection layer 56, which contains a conductive material.
[0071] The functional layer 50 is preferably designed as a single layer, which integrates a reinforcement layer 52, a camouflage layer 54 and a discharge protection layer 56.
[0072] Alternatively, the functions of the reinforcing layer 52, the camouflage layer 54, or the discharge protection layer 56 can be achieved in any combination within the plastic foil layer.
[0073] The quick-repair patch 36 may also have an information device 58 by means of which information about the quick-repair patch 36 and / or the quick repair performed thereon can be stored or retrieved. This information includes the type and manufacturing date of the quick-repair patch 36, the repair date, the repair location, and any other information (especially the type of technology associated with the quick-repair patch 36 or the repair itself). For example, the information device 58 may be a QR code or an RFID tag. QR codes and RFID tags can be used as references to corresponding information stored in a computer system or computer network, respectively. RFID tags may also be designed to directly contain this information.
[0074] The following will refer to Figure 4The rapid repair process is described in more detail. First, the damaged portion 28 is treated (e.g., by grinding) to provide a smooth, clean, dry, and grease-free bonding surface 60 for the rapid repair patch 36.
[0075] Next, a suitable quick-repair patch 36 is selected and placed on the damaged area 28, ensuring complete coverage. The quick-repair patch 36 is then pressed onto the component 26. Here, the plastic foil layer 40, especially the edge region 44, is pressed against the covering layer 34 and connected to it via the fastening layer 48. Furthermore, the lightning protection layer 42 is pressed against the lightning strike surface protection portion 32, creating electrical contact. If the lightning protection layer 42 is also coated with adhesive, it is also connected to the lightning strike surface protection portion 32 via the same material.
[0076] The following is for reference. Figure 5 The figure illustrates the quick-repair patch 36 as a presentation form of patch strip 62. Here, multiple quick-repair patches 36 are interconnected at separable edge regions 64 (e.g., by means of perforations). Patch strip 62 can be rolled up. The desired quick-repair patch 36 is separated from patch strip 62 before use.
[0077] To improve the rapid repair of localized and mechanically unrelated damage to components 26 of an aircraft, a rapid repair patch 36 is proposed. The rapid repair patch 36 has a layer structure 38 comprising a plastic foil 40 and an adhesive layer, on which a lightning protection layer 42 is applied, and the adhesive layer is disposed at least on the plastic foil 40. The rapid repair patch 36 can be adhered to the damaged portion 28, thereby placing the lightning protection layer 42 in electrical contact with the lightning protection layer of component 26. The rapid repair patch 36 may have a QR code or RFID tag for storing or retrieving information about the rapid repair patch 36 or the rapid repair performed by means of the rapid repair patch 36.
