Drawing of an experimental turbine by Viktor Kaplan, 1914


Viktor Kaplan personally signed and dated this drawing. It comes from the ‘Early Files’ archive holdings of the Technisches Museum Wien (Vienna Technical Museum).

Viktor Kaplan (1876 - 1934) came from Mürzzuschlag. His skills in technology and physics came to light early on, so Viktor Kaplan studied mechanical engineering at the Technical College in Vienna. After one year in the navy, he set up the ‘Ganz & Comp.’ machine factory in Leobersdorf in 1901. He made further developments to Rudolf Diesel's engine and was also preoccupied with the turbine models of James B. Francis and Lester A. Pelton. From 1903, he was a researcher and teacher at the German Technical College in Brno. Here he became acquainted with the major industrialist Ignaz Storek, who supported him financially, allowing him to establish his own turbine laboratory.

In Kaplan's constructions, volumes of water can be optimally used by a reduced number of rotating and angle-adjusted blade wheels. The turbine types that he developed ran faster than their predecessors and, because of their higher output, were particularly suitable for wide rivers in landscapes with gentle inclines and water levels that fluctuated throughout the year. This is why they were used, for example, in the Ybbs-Persenbeug power station, in the Isar valley (Bohemia) and in Lilla Edet (Sweden).

The first turbine built according to Kaplan's principle was constructed in 1918 by the steelworks of Ignaz Storek in Brno. In 1919, it entered operation in the ‘Börtel- und Strickgarnfabrik M. Hofbauers Wwe.’ (braid and yarn factory) in Velm near Gramatneusiedl (Lower Austria). This turbine was installed in front of the Technisches Museum Wien (Vienna Technical Museum) in 1960 and can today be seen in the Energy area.

Viktor Kaplan registered a total of 267 patents in 25 countries. He received numerous honours, such as an honorary doctorate from the Technical Colleges in Prague and Brno, as well as a gold medal from the Austrian Association of Engineers and Architects.
