If, in the airship according to the invention, loads are to be deposited on landing sites that have not been prepared for a gate, the lift is initially reduced by exchanging warm air for cold air in the bow and stern cells. The partitions that can be turned over in these cells against the steam buoyancy space inside the outer shell in the manner of a pointed cap are also double-walled and designed to be heat-insulating with drawstrings. It can therefore be blown in or sucked out of the partition walls, so that the passage of heat to block or little hindered; Can regulate passage. Based on this principle, the air temperature in the bow and stern trim cells can be changed independently of the steam room.An exchange of cold air for warm air makes for the generation of 1 t of lift - only 11 kg HelKÖl or 16 'obm natural gas (10O ⁰ C) necessary .. and this costs around DH 1.- to OH 1.50.

condense better and the latter happens advantageously Oaduroh, if the fresh air is blown through the bow and stern cells for a long time and thus the required amount of steam heat is dissipated. For this purpose, the partition is vented so that it has at least a hundred times better thermal conductivity than the insulating effect. The ballast water formed consumes the buoyancy of an equal amount of steam to a moderate degree. For new transport tasks, around 35 kg of heating oil or around 35 kg of heating oil for 1 t of buoyancy are required. 50 sr of natural gas at 100 C can be used to generate steam. The lifting costs for a load to be picked up are therefore only about 3.50 DH per 1000 kg. If this airship remains in suspension for an hour without the engine running, the buoyancy is achieved by burning 25 kg of heating oil or 35 %? Maintain natural gas at 100 ° C. With this size, an effective heat-emitting area of around 20,000 square meters is expected. Each minute hold time therefore costs about 0.05 DH.

Furthermore zei et Pig. Figure 6 shows a dash through the outermost bow part of the airship according to the invention. The compressed air generated by the preferred white diesel engines and the propellers or blowers in the keel frame is fed to the bow nozzle via an air supply pipe 18, which is also made of fabric materials. The air is distributed in an annular gap nozzle with a central nozzle body 20 and exits on the inside of the deflecting screen 19 adjacent to the bow body. In the interior of the lens body 20, an observer or helmsman can admirably pursue his activity. The deflecting screen 19 can be adjusted hydraulically to the side and at a distance from the Bugrande and the airship can be controlled with it. The screen can advantageously be folded up so that the front nozzle then blows out a jet against the normal direction of travel. In this way, it is possible not only to propel the airship according to the invention through the nose nozzle, as in the normal version, but also to brake it when the deflector is folded. The lateral deflection then takes place by moving the nozzle body from its central position to one side of the annular gap nozzle edge. The predominant air leakage from the bow duo on one side as a result

generates forces deviating from the axis line that lead to Long can be used for a short time -

Usually the air is in the bow and hoc & curpe? hot and therefore contributes significantly to the buoyancy of the Laft - ship. If the buoyancy force of the airship is to be changed, the hot air is replaced by cold air by means of the fan. Conversely, increased buoyancy can be obtained by increasing the air in these bow and stern bodies, whereby an overpressure due to the free running fan 19 is prevented
