'Kurt Waldemar Tank' (February 24 1898 - June 5 1983) was a resourceful German aeronautical engineer and test pilot, heading the design department at Focke-Wulf from 1931-45. He designed several important aircraft of World War II, including the Focke-Wulf Fw 190 fighter aircraft.
Before Focke Wulf, Tank was employed by Albatros Flugzeugwerke, but after their bankruptcy in 1929, the company was broken up with most of the designers going to Focke-Wulf and a few others going to Arado Flugzeugwerke in 1931.
Tank then started work on the design of the Fw 44, Focke Wulf's first commercially successful design, launched in 1934. This led to burgeoning growth for the company as the country prepared for war.
The Fw 190 Würger (butcher-bird), first flying in 1939 and produced from 1941 to 1945, was a mainstay Luftwaffe single-seat fighter and bomber during World War II, and Tank's most prolific (over 20,000 produced) and famous design. During the war, Tank was honoured for his work. In January 1943, he was named honorary Professor with a chair at the technical school in Braunschweig, in recognition of his services to the development of flight.
In 1944, the ''Reichsluftfahrtministerium'' (German Air Ministry) decided that new fighter aircraft designations must include the chief designer's name. Kurt Tanks new designs were therefore given the prefix Ta. His most notable late-war design was the Ta 152, a continuation of the Fw 190 design. The two major versions of the Ta 152 were the Ta 152 C, and the Ta 152 H. The H version had an increased wingspan to 47 feet 6 in., and a more capable engine to allow for better high-altitude performance. This ''Spezial Höhenjäger'' boasted excellent high-altitude performance, using a Jumo 213E engine, a 2-stage, 3-speed supercharger and the MW 50 methanol-water mixture engine boost system.
At the end of the war, like many other German technicians, he continued his professional life in Latin America. The Argentine Government offered him a job at its aerotechnical institute, the Instituto Aerotécnico in Córdoba under the name of (Prof. Dr.) Pedro Matthies. He moved there, with many of his Focke-Wulf co-workers, in 1947. One of these was Ronald Richter who intended to power airplanes with nuclear fusion power, to be developed in the Huemul Project which was proven to be a fraud.
The Instituto Aerotécnico later became Argentina's military aeroplane factory, the Fábrica Militar de Aviones. There, he designed the IAe Pulqui II based on the Focke-Wulf Ta 183 design that had reached mock-up stage at the end of the war. It was a state-of-the-art design for its day, but the project was axed in 1953 due to Argentina's financial crisis. When President Juan Perón fell from power in 1955 the ex Focke-Wulf team dispersed, many to the United States.
Tank instead moved to India. There he designed, for Hindustan Aeronautics, the Hindustan Marut fighter-bomber, the first military aircraft constructed in India. The first prototype flew in 1961; the Marut was retired from active service in 1985.
Tank returned to live in Berlin during the seventies, basing himself in Germany for the rest of his life.
