Definitions

  • the present invention relates to a camouflage having attenuating properties within the infrared and the microwave range in order to mask primarily military objects.
  • object as used herein, is meant installations, e.g. airfields, as well as equipment and personnel.
  • the invention is also concerned with a method at the generation of such a camouflage.
  • camouflage In order to camouflage an object, it is usually painted, covered with nets and the like or placed towards a suitable background. Characteristic of such camouflage is that it is effective mainly within the visible wave-length ranges. Within the infrared range and the microwave range, where a lot of search equipment and homing active parts are working, there have up to now been found no good camouflage methods.
  • the object of the present invention is to suggest a camouflage giving protection from search equipment provided with homing devices working within the infrared and microwave ranges.
  • camouflage of the present invention may primarily, but not exclusively , be used for the following applications:
  • the water-based foam may be an ordinary fire extinguishing foam, which is obtained in a way known per se by mixing water with a foaming agent which when being sprayed is added air with a foam production as the result.
  • the foam may comprise stabilizers and corrosion inhibitants.
  • the foam also comprises colouring agents usual for masking purposes.
  • foaming agents known for foam extinguishing purposes may be mentioned ammoniumlauryl ethersulfate, diethylglykol monobutylether and lauryl alcohol.
  • stabilizers there may be used in a conventional way gelatine, sodium carboxymethyl cellulose, polyethylene imine, starch phosphate, glycerol, sorbitol, fatty acid monoethanol amides, fatty acid amides, N-alkylimino diacetates or sulfobetaine.
  • corrosion inhibitants are carbamates, tetrasodium pyrophosphate and sodium benzoate.
  • the plastic-based foam consists of a cellular plastic, e.g. cellular urethane plastic, cellular phenol plastic or cellular carbamide plastic, produced in the conventional way. After mixing the components together and spreading of the foam obtained, the curing action may be performed in place.
  • the cellular plastic structure is obtained by vaporization of the blowing ° (expanding) agent being part of the reaction mixture or by air being blown into the reaction mixture.
  • Vehicles primarily combat vehicles, are usually pattern painted for masking purposes in order to be protected from direct view.
  • the pattern painting may be completed with bunches of twigs and the like being fixed to the vehicle.
  • the camouflage is completed with camouflage nets being tightened across and around the vehicle.
  • the foam In order to camouflage a combat vehicle from the air or in order to protect it from view from the ground the horizon around, it is necessary that the foam is put around the whole vehicle. Vertically the foam should cover the sides of the chassis and the upper parts of the front armour and the back armour. The barrel and prisms and sight equipment should be free from foam.
  • the foam could be put in a sector in front of the vehicle.
  • a water-based foam can be used. With an expansion ratio of about 1 000, it is required about 100 litres of water, 100 m air and about 1 litre of foaming agent in order to achieve a camouflage all around the vehicle.
  • a conventional foam blowing device having a number of muzzles.
  • the number is adapted in order that the foam will be produced as quickly as possible and that an acceptable continuous camouflage will be obtained.
  • the foam must be non-toxic as there is a risk of getting 9 foam inside the vehicle.
  • the camouflage of the invention is particularly suitable for masking antitank mines, something that has been difficult up to now and has required large resources.
  • the mines are buried by hand or are put into the ground by means of minelayers. Then the mines are being camouflaged by putting back on top of the mines, those pieces of turf that were loosened at the minelaying.
  • a camouflage is obtained by spreading a thin layer of gravel on the roadway, which layer is joined together using a slurry of asphalt or cement.
  • the clearance of mines is carried out by hand, by blasting or shooting or by means of a mine roller. Mine clearance by blasting or shooting must most often be completed with a removal of mines by hand. Removal by hand and even blasting does require that the individual mine is first , being located.
  • camouflage of antitank mines requires that a plastic-based foam is being used because of the long time such a camouflage must be able to stay.
  • the height should be about 0.5 cm in order to cover the mines and to make the mine clearance more difficult.
  • a mining that is laid on a road or buried into the roadway will have to be covered with foam over the entire width of the roadway.
  • camouflage according to the invention can be favourably used:
  • Airfields military as well as civil fields, are important objects in case of war.
  • the aggressor wishes to get hold of them undamaged in order to quickly supply troops and necessaries. Airfields that are not used are consequently barred (and defended) while airfields that are used by our air force, are being defended. Airfields that an aggressor does not intend to use will be combated by him in order to obstruct our air force. Said fields may be barred or used by our air force.
