Definitions

  • Camouflage has a high priority especially for military objects. These Camouflage can add visibility or recognizability in multiple radiation spectra, at Noise and other aspects concern.
  • the invention relates to multi-spectral camouflage, especially for military movable equipment, such as the camouflage of an armored vehicle, the from the usual parts such as drive motor, gears, wheelsets or chain drive, a crew room and a housing that houses all the additions and additions, composed, and / or fixed installations.
  • Known embodiments provide, for example, to make a vehicle as small as possible, among other things to achieve a high camouflage ability.
  • This effort has a limit when the vehicle is to be manned, since an operator has a certain Required space in a vehicle according to his height and its intended Activity in the vehicle and an unmanned vehicle is not generally applicable Way out solution. Therefore, a manned vehicle always has a minimum volume and geometric size. Also, a smaller object is in certain To locate spectra well today, so that smallness alone does not protect more generally.
  • An infrared warning as another example must be designed so that a vehicle as Heat body no or only a small difference to the surrounding heat radiation shows. This has been tried so far by constructive measures or by passive To achieve additional tanning agent.
  • a favorable arrangement of the components of a vehicle in the vehicle can have an effective camouflage effect, for example when infrared camouflage heat-loaded exhaust gases, which are used as exhaust gases of an internal combustion engine or as Cooling exhaust air of a process to be cooled incurred, before delivery to the ambient air Fresh air mixed and then these exhaust gases at the bottom and rear of the vehicle to the environment be dismissed and also generally hot spots outside the vehicle with a high Temperature gradient to the environment completely avoided.
  • camouflage means are not sufficiently able to be controlled at different To tailor backgrounds.
  • this disadvantage occurs in the thermal Infrared, because in this spectral range the variation of natural backgrounds especially is pronounced.
  • the object of the invention is to design and use a camouflage element in the thermal infrared meets a controlled adaptation to the current environment.
  • the camouflage is especially intended for all military platforms and installations, such as military and / or mobile equipment and / or a fixed installation, whose Signature in the thermal infrared range (2 to 15 ⁇ m wavelength) through active measures is controlled. The signature in the other spectral ranges is passively reduced.
  • the solution consists of a camouflage agent, which rinsed through as a base Core area with thermally coupled outer skin, whose thermodynamic Temperature is forcibly adjusted by heating and / or cooling.
  • the adaptation is done by a suitable controller.
  • the advantages of the invention are that there is no contradiction between optimal adaptation in the thermal infrared region and the high-frequency radar region.
  • the visible spectral range as well as the near infrared range are also good covered with the other spectral ranges for optimal camouflage.
  • the multispectral camouflage agent according to the invention based on a in its temperature controlled heat exchanger is characterized in that the heat carrier is gaseous is (for example air) and that the heat exchanger at the same time signature holder in the Spectral ranges visible light (VIS), near infrared (NIR) and thermal infrared (TIR) is. Furthermore, by the same element in addition, the reflection of high-frequency Radar radiation broadband reduced.
  • the heat carrier is gaseous is (for example air) and that the heat exchanger at the same time signature holder in the Spectral ranges visible light (VIS), near infrared (NIR) and thermal infrared (TIR) is.
  • VIS visible light
  • NIR near infrared
  • TIR thermal infrared
  • a solid support material is formed from a layer structure, the inside with a solid support material starts (typical, but not exclusive strength 2 ... 3 mm), then at least a layer of open-celled metal foam (typical but not exclusive bubble size 6 ... 10 bpi) with a typical but not exclusive thickness of 15 ... 25 mm and then again a solid support is applied.
  • the Layer construction made as described, but the top (visible) layer is made high-strength PzStahl manufactured, in order to achieve an increased ballistic protective effect.
  • the top (visible) Layer not of metal, but of a non-conductive material is formed by the open-cell metal foam broadband absorption and / or scattering of high-frequency radar radiation.
  • This radar-transparent Layer may also consist of ceramic and thus additionally one represent ballistic protection.
  • the thermal decoupling of the layer to the original outer wall reinforced by using a heat insulator under the heat exchanger can also be formed as a sufficiently sized layer of air be.
