Ernst Schmidt (thermodynamics)

from Wikipedia, the free encyclopedia

Ernst Heinrich Wilhelm Schmidt (born February 11, 1892 in Vögelsen near Lüneburg , † January 22, 1975 in Munich ) was a German thermodynamic scientist and university professor.

Life

The son of a farm owner graduated from the Johanneum Lüneburg in 1910 . He studied at the Technical Universities of Dresden and Munich first civil engineering before to study electrical engineering changed. He was a member of the fraternity Association of German Students (VDSt) in Dresden and Munich and in Gdańsk. In 1911/12 he did military service and took part in World War I from 1914 to 1918 . In 1919 he finished his studies with a degree in electrical engineering in Munich. He became a Dr.-Ing. did his doctorate and then worked under Oskar Knoblauch as an assistant in the laboratory for applied physics at the Technical University of Munich. In the years 1922–1925 he worked in industry. He completed his habilitation in 1925 at the TH Munich. In October 1925 he became a full professor of thermodynamics at the Technical University of Danzig and director of the technical laboratory there. In November 1933 he signed the professors' declaration of Adolf Hitler at German universities and colleges . Ernst Schmidt became a supporting member of the NSDAP in 1934. Hermann Göring appointed Ernst Schmidt in 1943 as "authorized representative for jet propulsion". As part of this function, Ernst Schmidt established the largest German research network for the development of solid rocket technology.

Activity in Braunschweig

From 1937 to 1945 he was a professor at the Technical University of Braunschweig and head of the "Institute for Engine Research " of the German Aerospace Research Institute in Braunschweig-Völkenrode. From 1945 to 1952 he held the chair for heat theory at the TH Braunschweig. Since 1944 he was a member of the Braunschweig Scientific Society .

Renewed activity in Munich

In the years 1952–1961, Schmidt was Wilhelm Nusselt's successor full professor for thermodynamics at the TH Munich, whose rector he was from 1956 to 1958. His successor on the chair and from 1972 also as rector was his academic student Ulrich Grigull .

plant

Schmidt invented the Alfol insulation ( aluminum foil ) and, in 1921, the heat flow meter . The Schmidt number (Sc) is named after him. It indicates the ratio of convective to diffusive mass transport. He has also done extensive research on the thermodynamics of rocket motors. In his standard work there is Chapter XV. "Thermodynamics of rocket propulsion" with lots of figures, also on liquid and solid fuels.

Awards

In 1956 Schmidt was awarded the Grashof commemorative coin from the Association of German Engineers . In 1958 he was elected a full member of the Bavarian Academy of Sciences . In 1964 he received the Bavarian Order of Merit . He was the recipient of the Ludwig Prandtl Ring and the Max Jakob Memorial Award .
