Most Schütte-Lanz airships were made of plywood rather than aluminum alloy. Despite this, Schütte-Lanz introduced many design innovations that were soon adopted by competitor Zeppelin. This is a late war example - probably 1918's SL22.

Schütte-Lanz (SL) is the name of a series of rigid airships designed and built by the Luftschiffbau Schütte-Lanz company from 1909 until the last LS22 was delivered in 1917.[1] One research and four passenger airships were planned for post-war use, but were never built. The Schütte-Lanz company was an early strong competitor of the more famous airships built by Ferdinand von Zeppelin.[1]

History[edit]

When the Zeppelin LZ 4 met with disaster at Echterdingen in 1908, Professor Johann Schütte started to consider the problems of airship design. He decided, with the co-operation of his students to develop his own scientifically designed, high performance airship. In partnership with Dr Karl Lanz, an industrialist and wood products manufacturer he started the Schütte-Lanz Luftschiffbau on April 22, 1909. The ships were successful at first, and introduced a number of highly successful innovations.[2]

Wood composites had a theoretical superiority as the structural material in airships up to a certain size. After that, the superiority of aluminum (and later duralumin) in tension was more important than the superiority of wood in compression. Schütte-Lanz airships until 1918 were composed of wood and plywood glued together. Moisture tended to degrade the integrity of the glued joints. Schütte-Lanz airships became structurally unstable when water entered the airship's imperfectly waterproofed envelope. This tended to happen during wet weather operations, but also, more insidiously, in defective or damaged hangars.[citation needed] In the words of Führer der Luftschiffe Peter Strasser:

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...[2]

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.[citation needed]

The German Navy had bases closer to the sea, and thus more humid. They were reluctant to accept wooden composite craft. As a result the primary customer for Schütte-Lanz airships was the German Army. The German Army decided well before the German Navy that airship operations were futile in the face of land-based heavier-than-air opposition.

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. By the time the last eight ships were ready, most of them could not be operated due to the loss of trained crews. There are also political-economic factors to the failure of the company, which have yet to be fully researched. There is certainly evidence[citation needed] for a pro-Zeppelin lobby in the German military and government that wanted to exclude all other airship manufacturers, regardless of what superior technical innovations they proposed.

In the postwar period, Professor[verification needed] Lanz designed a series of very large advanced airships for trans-Atlantic and trans-Pacific passenger operations (described below), as well as proposals for the US Navy’s rigid airships ZRS-4 and ZRS-5. However none of these were ever realized due to Allied objections.[2]

SL1[edit]

SL 1 under construction

The Schütte-Lanz airship SL1 was the first of 20 airships built by the company. Construction was carried out in a large hangar at Rheinau near Mannheim. The ship was powered by four 125 horsepower (93 kW) Daimler-Benz engines installed in two ventral gondolas. 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 SL1 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. The structure of the SL1 resembles the later "geodesic" structures of Barnes Wallis at Vickers or Buckminster Fuller's domes. 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. Fifty-three experimental flights were made between October 1911 and December 1912, the longest of over 16 hours. The ship was handed over to the German Army on December 12, 1912 but destroyed soon afterwards when it broke loose from its temporary mooring during a storm.

  • First Flight: October 1, 1911
  • Length: 131 metres (430 ft)
  • Diameter: 18.4 metres (60 ft)
  • Gas Capacity: 19,000 cubic meters
  • Performance: 38.3 km/h

SL2[edit]

The Schütte-Lanz airship SL2 surpassed the contemporary Zeppelin airships in performance. It adopted the Zeppelin ring-girder construction method, but retained the streamlined shape and plywood construction of the SL1. The SL2 was also the most significant airship to date in that it laid down two vital design innovations that were copied in almost all subsequent rigid airships. The first was the cruciform tail plane, with a single pair of rudders and elevators. The second was the location of the engines in separate streamlined gondolas or cars. A third innovation, for war service, was the mounting of heavy machine guns for defense against attacking aircraft in each of the engine cars. SL2 was built between January and May 1914 and transferred to Austrian military control. It carried out six missions in the first year of the war over Poland and France. After being enlarged in summer 1915, several more missions were carried out before SL2 was stranded at Luckenwalde on January 10, 1916 after running out of fuel and decommissioned. The SL2 was a perfect example why the advanced technology of Schütte-Lanz, and the advantages of wood in compression as opposed to tension allowed the Schütte-Lanz type of airship to be technically superior until a certain size had been reached.
