Hermann Landmann

from Wikipedia, the free encyclopedia

Hermann Ewald Landmann (born February 16, 1898 in Hermülheim , † January 29, 1977 in Dresden ) was a German aircraft designer and university professor .

Life

After his military service, Landmann studied mechanical engineering at the TH Aachen from 1919 to 1924 , where he joined the FVA in 1920 and developed his first aircraft La 1 "Pipö" there, which was flown in by Wolfgang Klemperer the following year . From 1926 he developed and built gliders and sport aircraft in Bonn and later in Stettin . In 1930 he became an assistant to Georg Madelung at the flight technology institute of the TH Stuttgart and in 1933 lecturer for aircraft construction at the technical center in Strelitz and from 1935 to 1945 lecturer for aerodynamics and flight mechanics in Stettin. In 1937 his book "Construction of Motor Airplanes" appeared. During the Second World War , he also worked for the Heinkel works in Rostock . In 1944 he was drafted into the Air Force and in May 1945 was taken prisoner by the Soviets, from which he was released four months later. After the end of the war, from 1945 onwards, Landmann worked successively as an aerodynamicist for wind turbines in Rostock and as a designer of hydrofoil boats in Roßlau . After its completion he taught from 1952 as a professor for design and construction of aircraft at the technical faculty of the University of Rostock .

In connection with the development of the East German aircraft industry in Dresden, on July 1, 1953, he was appointed professor of aerodynamics at the Faculty of Lightweight Construction - later the Faculty of Aviation - of the Dresden Technical University of that time, where between 1955 and 1962 he designed further aircraft which the motor sailers La 16 and La 17 were built and tested. After this faculty closed in 1961 until his retirement in 1963, he worked at the Institute for Lightweight Construction at the TU Dresden , but held courses at the Institute for Machine Elements until 1965/66.
