Karl Röder (engineer)

from Wikipedia, the free encyclopedia

Karl Röder (born November 16, 1881 in Mainbernheim ; † 1965 ) was a German mechanical engineer and designer of steam turbines .

Live and act

Röder studied at the TH Munich . During his studies in 1900 he became a member of the Cimbria Munich fraternity . From 1904 he worked at Maffei and Helms & Pfenninger in Munich. In 1912 he received his doctorate in Munich as Dr.-Ing. From 1914 to 1920 he was a senior engineer at the August Thyssen engineering works . He then worked as a consulting engineer in Mülheim. In 1914 he built the first 3,000-speed large Thyssen-Röder turbine . Röder's turbine design became an export hit under the name SSW-Röder . In 1924 Röder went to the Technical University of Stuttgart as a full professor for machine parts, transmission theory and machine science . In 1926 he moved to the TH Hanover to the chair for steam engines and was chairman of the machine laboratory A (steam engines) and the power and heating plant. He tried to develop the axial counter- rotating turbine as a counterpart to the radial Ljungström turbine and built the first high-speed counter-pressure turbine in overpressure design (Röder design), which is characterized by good efficiency and, due to "breathing internals", thermal elasticity and high operational reliability.

In November 1933 he signed the German professors' confession of Adolf Hitler .

In 1947 Röder retired.

The city of Mainbernheim granted Karl Röder honorary citizenship in 1950 .
