Hermann Föttinger
Encyclopedia
Hermann Föttinger was a German engineer and inventor. In the course of his life he submitted over 100 patent
applications, but he is most notable for inventing fluid coupling
.
From 1895 to 1899 Hermann Föttinger studied electrical engineering at the Technical University of Munich
. From 1904 he worked as a chief designer in the shipyard AG Vulcan Stettin. He was responsible for the introduction and testing of new steam turbines. During this time he developed the fluid coupling
consisting of a pump and a turbine in a unit that in further development resulted in the automatic automobile transmission.
In 1909 he obtained a position at the Gdańsk University of Technology
where he started the institute for fluid dynamics
technology.
In 1924 he took up a position as head of the current department of physics and Turbines at the Technical University of Berlin
. Here he remained until his death from grenade fragments in April 1945.
Föttinger laid the basis of the fluid dynamics from Euler
over Rankine
and Hermann von Helmholtz
to its current uses in the boundary layer of airplane wings and propulsion theory.
Together with Franz Kruckenberg
he started the Flugbahn-Gesellschaft mbH to develop the Schienenzeppelin
s (railroad cars).
