Leonid I. Sedov

Leonid Ivanovich Sedov (Russian Леонид Иванович Седов, English transcription Sedov; born November 1, 1907 in Rostov-on- Don, † September 5, 1999 in Moscow) was a Russian scientist of Applied Mathematics and Mechanics.

Life

Sedov made ​​in 1930 graduated from the Moscow State University and was thereafter until 1947, scientists at the Central Aero - Hydrodynamic Institute. At the same time, he was from 1937 professor at the Moscow State University. He received his doctorate in 1936 Sergei Alexeyevich Chaplygin and Nikolai Zhukovsky Jegorowitsch and his habilitation (Russian PhD ) Mikhail Alekseevich Lavrentiev 1938 ( theory of plane- parallel flow in liquids ) From 1945 he worked at the Steklov Institute.

Sedov is known for the development of mathematical solutions in hydrodynamics and aerodynamics, for example, for the propagation of shock waves and the modeling of the impact of bodies. He treated the aerodynamic problem of the flow and the forces on deformable wings and non-stationary flow problems to airplane wings. He became known for his already occurred during the Second World War mathematical modeling of explosions. He turned to similarity transformations and examined self-similar solutions, which he published a book. Some of these investigations ran parallel to those of Western scholars like Geoffrey Ingram Taylor about the same time. He developed models of continuum mechanics taking into account electrodynamic and thermodynamic effects and formulated a variational principle for the derivation of equations of motion and boundary conditions in continuum mechanics.

He was also involved in the Soviet space program in a managerial capacity. For example, in 1955 he was a member of the Soviet Commission in Copenhagen, which announced the launch of the Sputnik satellite. This was the first official announcement of the Soviet Union on the existence of its space program. 1961 and 1962 he was President of the International Astronautical Federation. In 1965, he stood in front of the Department hydro-and aerodynamics of the Soviet Academy of Sciences.

In 1946 he became a corresponding member of the Soviet and 1953 full Academy of Sciences. In 1967 he was Hero of Socialist Labor. In 1952 he was awarded the USSR State Prize and four times the Order of Lenin. He was a knight of the Legion of Honour.
