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. Both doors form a semi-circle in plan and a quarter-segment of a circle in elevation. 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. 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. But he needs a clever man who tells him whether there really is a way from the place his customer has build his giant steel crane to the place where it is needed on which all streets can carry the weight. Currently, a new generation of airships (helium filled, carbon fibre structure, length 260 m), the CargoLifter CL-160 is prepared. After the breakdown of the Cargolifter project he can now expand business. But the global market and ecological needs require the search for new forms of transportation. This week CargoLifter outlined its plans again at the 14th American Institute of Aeronautics and Astronautics Lighter-Than-Air Technical Committee Convention and Exhibition in Akron, Ohio.Six decades ago the golden age for the airships – succeeded by airplanes – seemed to have died forever. CargoLifter hopes to pull in revenue using the CL 75 in Canada by the third quarter of 2002. The balloon can be towed by trucks, ships or helicopters, as well as a stationary winch-cable device. While readying to get the big ship off the ground, the company will focus on a transport balloon it calls an “AirCrane” that can lift 75 tons. The company cites these overruns and date setbacks as part of the price for bringing a major technological effort to market. And the initial cost projections for producing the CL 160 have jumped from 80 million euro (about $68 million) to 590 million euro (about $502 million). The CL 160’s viability has been called into question by the German press, as the dates of the first flights have been pushed back. Die 1996 gegründete Firma beschäftigte sich mit der Entwicklung eines neuartigen Luftschiffes, den CargoLifter. Zwischenschein 500 Aktien, Frankfurt 2000.

Now being tested, the unmanned CL 75 “AirCrane” can tote up to 75 tons, the company says. The airship need not land to unload its cargo, which is why it is sometimes referred to as a “flying crane.” The payload can be discharged while the CargoLifter hovers at 300 feet. When the CargoLifter reaches its destination, ground cables are connected and water is pumped into the CL 160 to hold it in place if a cable breaks. Another four CT-7 engines maneuver the airship. Once aloft, the airship can reach a maximum altitude of 6,000 feet, propelled by four 1,900-horsepower General Electric CT-7 helicopter engines. The weight of the payload is distributed along the keel.Ĭoming out of the hangar, the CL 160 attaches to a mobile mast that is pulled along by a rail car. And unlike a blimp, the CargoLifter has a keel, which runs along the underside of the helium-filled envelope. Zeppelins have rigid skeletons, while the CargoLifter holds its shape from internal pressure of the helium. Edwards notes that the CargoLifter CL 160 isn’t really a zeppelin, but a semi-rigid airship.
