Question: What is the Joukowsky transform designed by  Father of Russian Aviation Nikolai Zhukovsky?
Context: Zhukovsky (Russian: Жуковский ) is a 1950 Soviet biopic directed by Vsevolod Pudovkin and Dmitri Vasilyev, based on the life of Russian scientist Nikolai Zhukovsky (1847–1921), founding father of modern aero- and hydrodynamics.  In 1950 Pudovkin received the Best Director award at the 5th Karlovy Vary International Film Festival for this film.  In 1951 Pudovkin, Shebalin, Golovnya, and Belokurov received the Stalin Prize. The Tsar Tank (Russian: Царь-танк ), also known as the Netopyr' (Нетопырь) which stands for "Pipistrellus" (a genus of bat) or Lebedenko Tank (танк Лебеденко), was an unusual Russian armoured vehicle developed by Nikolai Lebedenko (Николай Лебеденко), Nikolai Zhukovsky (Николай Жуковский), Boris Stechkin (Борис Стечкин), and Alexander Mikulin (Александр Микулин) from 1914 onwards.  The project was scrapped after initial tests deemed the vehicle to be vulnerable to artillery fire. In applied mathematics, the Joukowsky transform, named after Nikolai Zhukovsky, is a conformal map historically used to understand some principles of airfoil design. The Central Aerohydrodynamic Institute (Russian: "Центра́льный аэрогидродинами́ческий институ́т" , "ЦАГИ", transliterated as "Tsentralniy Aerogidrodinamicheskiy Institut", TsAGI) was founded in Moscow by the pioneer of Russian aviation, Nikolai Yegorovich Zhukovsky on December 1, 1918. The Kutta–Joukowski theorem is a fundamental theorem of aerodynamics used for the calculation of the lift of an airfoil and any two-dimensional bodies including circular cylinders translating in a uniform fluid at a constant speed large enough so that the flow seen in the body-fixed frame is steady and unseparated.  The theorem relates the lift generated by an airfoil to the speed of the airfoil through the fluid, the density of the fluid and the circulation around the airfoil.  The circulation is defined as the line integral around a closed loop enclosing the airfoil of the component of the velocity of the fluid tangent to the loop.  It is named after the German Martin Wilhelm Kutta and the Russian Nikolai Zhukovsky (or Joukowski) who first developed its key ideas in the early 20th century.  Kutta–Joukowski theorem is an inviscid theory, but it is a good approximation for real viscous flow in typical aerodynamic applications. In fluid dynamics, circulation is the line integral around a closed curve of the velocity field.  Circulation is normally denoted Γ (Greek uppercase gamma).  Circulation was first used independently by Frederick Lanchester, Wilhelm Kutta, and Nikolai Zhukovsky. TESIS Aviation Enterprise was a cargo airline based in Moscow, Russia.  It operated domestic and international charter cargo flights from Moscow to destinations including China, India, United Arab Emirates and Turkey.  It also flies passenger charters around the world.  It was established and started operations in November 1992.  Its main bases were Domodedovo International Airport, Moscow and Irkutsk Airport.  The Russian aviation authority is suspending flights effective 17 October 2008.  The airline has not been taken over by Russian aviation fuel supplier TOAP that has blamed the credit crisis for the failure of the plan.  It has then suspended operations with its two remaining B747-200F freighters on October 17, 2008. Transform - which also includes Transform Aviation LLC and DifEQ Consulting LLP - is a management consulting, technology services and process improvement firm.  The entities comprising the Transform brand are registered in the state of Georgia.  Transform currently focuses on two key industries: Aviation and Government.  It is said to be a leader for technology services in the aviation industry.  Transform's current and former clients include 40+ airlines and aviation organizations, several large US-based health systems, the Department of Defense (through an approved GSA MOBIS Schedule, Contract Award Number GS-10F-0075V), and many of the Fortune 500. Aeroflot Flight 498 was a Soviet domestic passenger flight from Severomuysk to Ulan-Ude that crashed near Lake Baikal on 14 June 1981 en route to its planned stop at Nizhneangarsk Airport, Nizhneangarsk.  All 44 passengers — including 13 children — and 4 crew members on board were killed, and the aircraft was destroyed.  It remains the deadliest crash involving an Ilyushin Il-14.  At the time, it was the 30th-worst accident in Russian aviation history and is now the 50th-worst Russian aviation accident. Prof Nikolay Yegorovich Zhukovsky (Russian: Никола́й Его́рович Жуко́вский ; January 17 [O.S. January 5] 1847  – March 17, 1921) was a Russian scientist, mathematician and engineer, and a founding father of modern aero- and hydrodynamics.  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.
