Anton FlettnerBorn 1 Nov 1885; died 29 Dec 1961 at age 76.German inventor who produced a practical helicopter for the German navy (1940). He also developed a device that allowed airplane pilots to raise or lower a plane's nose for better control. It evolved into a mechanism called the Flettner trim-tab control which is still used on all airplanes. He designed a rotor ship (1924) on which he replaced sails with unique propulsion - two 50-ft cylinders, electrically rotated, mounted vertically on the deck. A transatlantic voyage was accomplished using the aerodynamic power of the Magnus Effect which builds pressure behind a rotating cylinder. After WW II, he went to the U.S., and conducted helicopter research for the U.S. Army. He also invented a windmill and the Flettner marine rudder.« |
