Hangar 7 - Airport Düsseldorf
Intercrimped wire mesh provides shielding of radar at the Düsseldorf International Airport.
Technology in line with Architecture
Air Traffic Control regulations require, that new buildings like Hangar 7 at Düsseldorf International Airport are verified for radar and ILS compability (ILS = Instrument Landing System). Radar shadowing and reflexion interferences at certain equipment must be avoided at all times. For such appraisals the altitude, landing and glide paths of the aircraft as well as the as the architecture of the building are taken into consideration.
If interferences exist, the appraisal typically suggests methods to dejam them accordingly. Since Hangar 7 is facing a radar system, the building is considered to be "radar relevant" and appropriate measures had to be incorporated.
To dejam the building it was suggested to install a metal marquee - made from wire mesh - at a 45 degree angle. The wavelength of the radar dictates the mesh type and specially the opening. Based on this the woven wire mesh specification DOKAWELL-MONO 3751 was chosen and used.
Haver & Boecker supplied and installed 87 elements, each 13.485 x 2380 mm in size. Each mesh panel was equipped with flat tension profile and clevis bolts, a system which allows for an easy installation. The intermediate mountings were realized with wire connectors, which are clipped to round tubes.
Haver & Boecker Architectural Wire Mesh not only impresses visually, they also fulfill many technical requirements. At Hangar 7, the technical features are the main reason for the use of wire cloth - by choosing according specifications buildings can also upgraded from a visual and design standpoint.
