Nikolay Yegorovich Zhukovsky ( rus, Никола́й Его́рович Жуко́вский, p=ʐʊˈkofskʲɪj; – 17 March 1921) was a Russian scientist, mathematician and engineer, and a founding father of modern aero- and
hydrodynamics In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases. It has several subdisciplines, including (the study of air and other gases in ...
. Whereas contemporary scientists scoffed at the idea of human flight, Zhukovsky was the first to undertake the study of airflow. He is often called the ''Father of Russian Aviation''. The
Joukowsky transform In applied mathematics, the Joukowsky transform (sometimes transliterated ''Joukovsky'', ''Joukowski'' or ''Zhukovsky'') is a conformal map historically used to understand some principles of airfoil design. It is named after Nikolai Zhukovsky, ...

, through his circulation hypothesis, the first to establish that the lift force generated by a body moving through an ideal fluid is proportional to the velocity and the circulation around the body. He is credited with the Joukowsky airfoil - an ideal shape of the aerodynamic profile having as essential elements a rounded nose (leading edge), double surface (finite thickness), cambered or symmetrical, and a sharp tail (trailing edge). He built the first

. In December 1918 at Zhukovsky's proposal and with his active participation, the Soviet government founded the Central Aerohydrodynamic Institute (TsAGI), of which he became the first head. At the same time, theoretical courses for military pilots were founded, later transformed into the Moscow Aviation Technical College. The Institute of Engineers of the Red Air Fleet was established on its base in 1920, and in May 1922 it became the Air Force Engineering Academy named after Zhukovsky. Zhukovsky died in
