Henrich Focke

Henrich Focke (8 October 1890 – 25 February 1979) was a German aviation pioneer from Bremen and also a co-founder of the Focke-Wulf company. He is best known as the inventor of the Fw 61, the first successful, practical, and fully controllable helicopter, first flown in 1936. He has been called "father of the helicopter".

Biography

Early life

Henrich Focke was born in Bremen on 8 October 1890, Focke studied at Leibniz University Hannover, where he became friends with Georg Wulf in 1911. In 1914, he and Wulf both reported for military service and Focke was deferred due to heart problems, but was eventually drafted into an infantry regiment. After serving on the Eastern front, he was transferred to the Imperial German Army Air Service.

Focke graduated in 1920 as Dipl-Ing with distinction. His first job was with the Francke Company of Bremen as a designer of water-gas systems.

Focke-Wulf and Focke-Achgelis

In 1923, with Wulf and Dr. Werner Naumann, Focke co-founded Focke-Wulf-Flugzeugbau GmbH. In 1927 Wulf died while test flying the Focke-Wulf F 19 canard monoplane.

In 1930 Focke was offered a chair at the Danzig Institute of Technology, an honour which he declined. In 1931 the city of Bremen awarded him the title of Professor. The same year, Focke-Wulf was merged with the Albatros Flugzeugwerke company.

Focke-Wulf constructed Juan de la Cierva's C.19 and C.30 autogyros under license from 1933, and Focke was inspired by it to design the world's first practical helicopter, the Focke-Wulf Fw 61, which first flew on 26 June 1936 by Ewald Rohlfs. In 1938, Hanna Reitsch piloted the Fw 61 inside the Deutschlandhalle.

While working at the CTA Focke also developed the BF-1 Beija-Flor (hummingbird) two-seater light helicopter from 1954, which made its first flight at Sao Jose dos Campos on 22 January 1959. The BF-1 was similar in design to the Cessna CH-1, with a 225 hp Continental E225 engine in the nose and the rotor mast running vertically between the front seats. An open structure tubular steel tail boom carried a pair of tail surfaces and a small tail rotor. The BF-2 was developed from this and first flew on 1 January 1959, and performed an extended flight-testing campaign until it was damaged in an accident. It is thought that further work on the Beija Flor was then abandoned.

After Borgward collapsed in 1961, Focke became a consulting engineer with Vereinigte Flugtechnische Werke of Bremen and Deutsche Forschungsanstalt für Luft-und Raumfahrt. Focke was awarded the Ludwig-Prandtl-Ring from the Deutsche Gesellschaft für Luft- und Raumfahrt (German Society for Aeronautics and Astronautics) for "outstanding contribution in the field of aerospace engineering" in 1961. Focke died in Bremen on 25 February 1979.

In 1993, Focke was inducted into the International Air & Space Hall of Fame at the San Diego Air & Space Museum.
