Kurt Hohenemser

Kurt Heinrich Hohenemser (January 3, 1906 – April 7, 2001) was a German-born American aerospace engineer and pioneer in the field of helicopter design.

[3][4] From 1930 until 1933, Hohenemser taught and conducted research at the University of Göttingen under Ludwig Prandtl, one of the most famous aerodynamics physicists during the 20th century.

[2] There were plans for BMW to mass-produce 1,000 Flettner Fl 282 helicopters but they were disrupted when allied forces bombed the designated factory.

[2] Hohenemser and Anton Flettner, who together developed numerous patents in Germany, maintained close contact after both men emigrated to the United States.

[1] Hohenemser later accepted a position as chief aerodynamics engineer of the helicopter division of McDonnell Aircraft in St. Louis, Missouri.

[1] Kurt Hohenemser, a longtime colleague and confidant of Anton Flettner, worked his remaining years in the United States to prove Flettner's idea that properly designed flexible helicopter-type rotors are more suitable for producing electricity from the wind than rigid airplane-type rotors.

Flettner Fl 282 "Kolibri" was an early ancestor of helicopters with intermeshing rotors
