The top chords (diameter 559 mm) are at 3.441 m centres and the bottom chords (559 mm) at 2.0 m centre. The arches of the cylindrical part have a structural height of 8 m and span over 225 m. The structure has been designed using steel grade S355. In addition, this solution is suitable to avoid excessive wind turbulence. The shape of the building is oriented closely on the clearance diagram for two airships. In this study, a PEB frame of 22 meter width is taken into. The structure is proposed as a Pre -Engineered Building of 79.3 m eters width, 10 bays each of 8.48 meters length and an eave height of 22 meters. Both doors form a semi-circle in plan and a quarter-segment of a circle in elevation. The present stu dy is included in the design of an Aircraft Hanger structure located at Mumbai. The canopy provides an excellent all-round field of view. The pilot sits on an MDD Escapac IC-7 ejection seat under a blown clamshell canopy that hinges open from the rear. The central part is of a cylindrical shape consisting of five steel arches at 35 m centres – each of the four bays being covered with a textile fabric – and at both ends of the building are the doors which consist of two fixed and six moving elements. It was broken down, loaded onto a Lockheed C-5A cargolifter, flown to Edwards AFB, and then reassembled to perform its first flight on 27 July 1972. The structural concept distinguishes two main parts of the building. Currently, the detailed design is taking place and most of the building structure should be ready in 1999. With a span of 210 m, a height of 107 m and a length of 363 m it will be the largest hall in Germany.
The site is an airfield in Brand, about 50 km south of Berlin. In the middle of 1997 the CargoLifter AG commissioned the design for an airship hangar in Germany to house two new airships. This airship allows transporting a pay-load of 160t over a distance of up to 10’000 km with a speed of 80-120 km/h. Currently, a new generation of airships (helium filled, carbon fibre structure, length 260 m), the CargoLifter CL-160 is prepared. But the global market and ecological needs require the search for new forms of transportation. Six decades ago the golden age for the airships – succeeded by airplanes – seemed to have died forever.
