Les promoteurs du Cargolifter visent le transport de charges lourdes et volumineuses. 2, record 1, French, - Cargolifter Record number: 1, Textual support number: 1 CONT Record number: 1, Textual support number: 1 DEFĭirigeable géant. The average speed will be about 100 km/h, which requires about 5 MW and an hourly fuel consumption of 1 tonne (specific fuel burn approx. Installed power is expected to be 9.3 MW, for a top speed of 135 km/h. CargoLifter will use marine diesel engines and propellers for thrust. The remaining 44t can take 2800 cubic meters of space (weight to volume of 1:62). The weight alone would account for 136t or 85% of the payload. The CargoLifter can take 72 TEU in a box, but the weight volume ratio is very low (1:20).
The loading cycle will take about half a day to unload and 3/4 days to load. Transport times are cut by a factor of 10 and the complexity of the project is reduced significantly. The advantage of CargoLifter is, that transport can take place in rural areas with little or no infrastructure. Goods up to the size of 12 x 5 x 5 m can be carried at a speed of 100 km/h. The CargoLifter is an airship, which can carry up to 160t of freight like a crane. All the chords of the truss-arch are brace-connected to each other by diagonals (355 mm) and posts (273 mm), with the exception of the two bottom-chords these are connected by only straight members (355 mm) at 4.135 m, forming a Vierendeel-system.Record number: 1, Textual support number: 1 CONT 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. 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.
