Definitions

  • the invention relates to the support structure of a vehicle, in particular of an aircraft, with an outer structure-compliant antenna and in particular a flat broadband antenna and, wherein the support structure is in particular a primary structure.
  • aircraft refers to all conceivable devices that can be moved with any drives through the air, such as aircraft, helicopters, airships, drones, rockets and the like.
  • the rockets are an example of how the invention may also relate to aircraft or missiles capable of flying both in the air and in a vacuum.
  • Air-supported pivotable reflector antennas are currently available as commercial products. However, their housing is usually a problem. It has therefore already been considered, instead of using a relatively large reflector antenna parts, for example, the aircraft surface as a radiating aperture.
  • the US 5,184,141 describes a multilayer carrier structure with an integrated outer structure-compliant antenna of an aircraft.
  • the antenna is arranged between two adjacent layers, wherein the inwardly directed layer may be an adhesive layer.
  • a further outer structure-compliant antenna is described, which is incorporated in the trough of a support structure.
  • the antenna is covered with a cover plate which is fixed with a circumferential nose, which engages in a groove provided on the support structure.
  • the cover plate is continuously formed as a plane-parallel plate, which rests at their edges on a support surface of the support structure, which is parallel to the outer contour.
  • the invention has the object of integrating outer structure-compliant antennas in such a way in the support structures of vehicles and / or aircraft, that any aerodynamic disadvantages are avoided and the structural strength is largely retained in the integration areas, while ensuring the antenna functionality.
  • an outer structure-compliant antenna in the form of a flat EM function core is frictionally embedded in a corresponding indentation of a support structure in such a way that the upper or outer cover of the antenna is realized in outer structure conformity by a cover plate, which in turn also frictionally engages in its edge regions connected to the support structure.
  • the frictional connection is realized by an adhesive layer.
  • the above-mentioned cover plate is advantageous for antenna-technical reasons designed as a so-called front dielectric.
  • the invention thus offers significant weight and volume savings over conventional antenna designs, which are particularly advantageous for aircraft. Aerodynamic disadvantages can not occur at all within the scope of the invention, since the shape of the outer skin of the structures remains completely unchanged. Practical investigations have in the meantime shown that the structural strength is at best influenced to a negligible extent by the invention.
  • structure-integrated antennas according to the invention offer the possibility of arrangement in areas which up to now have been unacceptable or even unsuitable for conventional antennas.
  • antennas can be installed and also in refueled structures when appropriate precautions are taken in terms of high-frequency lines.
  • the structural integration of the antenna according to the invention leads to a considerable potential with regard to the reduction of the radar signature compared to conventional antenna designs.
  • the antennas according to the invention are also suitable for use in stealth aircraft (stealth aircraft).
  • FIG. 1a illustrates very clearly the advantages of an antenna according to the invention over a conventional antenna according to the illustration 1 b.
  • FIG. 1a is a completely outer structure-compliant antenna subsystem, for example, for a broadband data link in the microwave range, shown.
  • the integration of the antenna into the aircraft structure according to the invention avoids any aerodynamic disadvantages that could arise from an antenna with the greatest possible preservation of the structural strength.
  • the antenna according to the invention based on a low reflection factor, has a large relative high-frequency bandwidth.
  • the invention thus offers a real alternative to the conventional antennas, especially to the in Figure 1b shown reflector antennas, especially in the context of the invention comparable electronic properties be achieved at the same time significantly lower installation volume and lower mass.
  • the invention provides, especially in aircraft structures additional arrangement areas for antennas, which are inaccessible to conventional antennas for various reasons.
  • FIG. 2 shows an example of the structure of an antenna, for example in planar design according to the invention in its essential individual parts.
  • the basis for the attachment of the antenna here forms a support structure 1 of an aircraft, which consists in many applications of CFRP.
  • the actual electromagnetic (hereinafter referred to briefly as EM) functional core 2 of the antenna is connected to the carrier system primary structure 1 via a suitable adhesive layer 3.
  • the essential upper or outer structure-adapted termination of the antenna is formed by a cover plate in the form of a so-called front dielectric 4, which is likewise connected to the electromagnetic functional core 2 via an adhesive layer 3.
  • the cover plate is preferably formed of a fiber composite material having the following fiber / matrix combinations: fused silica / epoxy, E-glass / epoxy or Q-glass / polyester.
  • the congruent bore rows 6 and 7 are openings for the electrical wiring of the outer structure-compliant antenna according to the invention.
  • the total thickness of the antenna according to the invention is preferably a few millimeters, so that their integration into an aircraft structure means no or at most only a negligible structural interference.
  • the Figure 3 shows a possibility of optimal introduction or integration of an antenna in the support structure 1, for example in an aircraft.
  • the support structure 1 has a trough 8 or a region-wise depression, which is brought about by acute-angled bending of the regions 9 and 10 of the support structure 1.
  • obtuse-angled or stepwise transitions can also be realized;
  • the region 9 of the support structure 1 could be bent downwards in an extreme case, so that the EM function core 2 could likewise be rectangular in its edge regions.
  • the angle ⁇ should remain acute-angled, since its size depends on the size of the adhesive surface in the region 10 of the structure 1 for the corresponding bevelled part 11 of the front dielectric 4; the smaller, that is, the more acute the angle ⁇ is, the greater is the adhesive area in the area 10 of the support structure 1.
  • the area 9 provides in radial view space for the accommodation of the EM function core 2, while the bending of the support structure 1 in the area 10 allows the load-bearing, outer contour-preserving gluing a cover plate in the form of a front dielectric 4.
