Career
From 1895 to 1899 Hermann Fottinger studied electrical engineering at the Technical University of Munich.
AG Vulcan Stettin
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.
Gdansk University of Technology
In 1909 he obtained a position at the Gdansk University of Technology where he started the institute for fluid dynamics technology.
Technical University of Berlin
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.
Fluid dynamics
Fottinger 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.
Railcars
Together with Franz Kruckenberg he started the Flugbahn-Gesellschaft mbH to develop the Schienenzeppelins (railroad cars).
Internal combustion engines
Fottinger's patents for internal combustion engines include:
