Schütte-Lanz
From Wikipedia, the free encyclopedia
Schütte-Lanz is the name of a type of rigid airship designed and built for the first time in 1909 which was a successful early competitor of the more famous airships built by Ferdinand Graf von Zeppelin.
When the Zeppelin LZ4 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.
Twenty-four Schütte-Lanz airships were designed before the end of the First World War, 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 losses of trained crews and also the serious problems that had developed with their wooden structures. 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...
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.
In the postwar period, Professor Lanz designed a series of very large advanced airships for transatlantic and transpacific passenger operations, 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.

[edit] SL1
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. Fifty-three experimental flights were made between October 1911 and December 1912. The longest flight was over 16 hours. The ship was handed over to the German army on December 12, 1912 but destroyed soon afterwards when it was swept free of its temporary mooring in a storm.
- First Flight: October 1, 1911
- Length: 131 meters
- Diameter: 18.4 meters
- Gas Capacity: 19,000 cubic meters
- Performance: 38.3 km/h
- Payload: 4.5 tonnes
- Engines: 4 Daimler 500 hp/370 kW total
[edit] SL2
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 SL1. 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 6 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.
