Fifty-three experimental flights were made between October 1911 and December 1912, the longest of over 16 hours. It was only matched at the time by the structure of the MacMeecham airship, designed and partially built in England in the first years of World War I. The structure of the S.L.1 resembles the later " geodesic" structures of Barnes Wallis at Vickers or Buckminster Fuller's domes. The S.L.1 was constructed with a diamond lattice frame and had a highly streamlined shape, allowing it to achieve a record speed of 38.3 km/h (23.8 mph 20.7 kn). A distinctive feature of the Schütte-Lanz ships was that the frame was constructed from special plywood which was (supposedly) waterproofed and protected from frost. The ship was powered by four 125 hp (127 PS 93 kW) Daimler-Benz engines installed in two ventral gondolas. Construction was carried out in a large hangar at Rheinau near Mannheim. The Schütte-Lanz airship S.L.1 was the first of 20 airships built by the company. ĭata from: Zeppelin:rigid airships 1893-1940 S.L.1 (Type 'a') However none of these were ever realized. In the postwar period, Lanz designed a series of very large airships for trans-Atlantic and trans-Pacific passenger operations, as well as submitting a proposal for the US Navy’s rigid airships ZRS-4 and ZRS-5. By the time the last eight ships were ready, most of them could not be operated due to the loss of trained crews. Twenty-four Schütte-Lanz airships were designed before the end of the World War I, most of which the company was not paid for due to the collapse of the German Monarchy. The German Army decided well before the German Navy that airship operations were futile in the face of land-based heavier-than-air opposition. As a result, the primary customer for Schütte-Lanz airships was the German Army. They were reluctant to accept wooden composite craft. The German Navy had bases closer to the sea, and thus more humid. The decision was made to compensate the company for the unusable wooden ships, and in response the company started work on a tubular aluminum-framed ship which was probably not completed. Most of the Schütte-Lanz ships are not usable under combat conditions, especially those operated by the Navy, because their wooden construction cannot cope with the damp conditions inseparable from maritime service. In the words of Führer der Luftschiffe Peter Strasser: This tended to happen during wet weather, but also, more insidiously, in defective or damaged hangars. Schütte-Lanz airships became structurally unsound when water entered the airship's imperfectly waterproofed envelope. Moisture tended to degrade the integrity of the glued joints. Schütte-Lanz airships until 1918 were made of wood and plywood glued together. Wood composites had a theoretical superiority as the structural material for airships up to a certain size, after which the superior strength of aluminum (and later duralumin) in tension was more important than the superior strength of wood in compression. The airships were successful at first, and introduced a number of highly successful innovations. In partnership with Dr Karl Lanz, an industrialist and wood products manufacturer, he started constructing the Schütte-Lanz Luftschiffbau on 22 April 1909. He decided, with the co-operation of his students, to develop his own scientifically designed, high performance airship. Publishers use these marks when books are returned to them.When the Zeppelin LZ 4 met with disaster at Echterdingen in 1908, Professor Johann Schütte (1873-1940) started to consider the problems of airship design.
