History
The development of the rotor aircraft was inspired by Flettner's rotor ship. The rotor ship, the Buckau, now renamed the "Baden-Baden," successfully crossed the Atlantic Ocean on 9 May 1926, and docked in New York, where it attracted considerable attention. The image shows the prototype of the rotor aircraft in an American shipyard at Hudson, New York. At that time, corresponding developments were made in Germany already.
The development of this unusual aircraft based on research by Ludwig Prandtl at the Aerodynamic Research Institute (AVA) in Göttingen. Prandtl experimented with rotating cylinders in the wind tunnel. The cylinders created up to ten times more lift than a plane wing.
More recently, the "iCar 101" project suggests the use of flettner rotors in roadable aircraft design to combine compactness and increased lift potential.

Famous quotes containing the word history:
“The history of mankind interests us only as it exhibits a steady gain of truth and right, in the incessant conflict which it records between the material and the moral nature.”
—Ralph Waldo Emerson (1803–1882)
“It may be well to remember that the highest level of moral aspiration recorded in history was reached by a few ancient Jews—Micah, Isaiah, and the rest—who took no count whatever of what might not happen to them after death. It is not obvious to me why the same point should not by and by be reached by the Gentiles.”
—Thomas Henry Huxley (1825–95)
“In the history of the human mind, these glowing and ruddy fables precede the noonday thoughts of men, as Aurora the sun’s rays. The matutine intellect of the poet, keeping in advance of the glare of philosophy, always dwells in this auroral atmosphere.”
—Henry David Thoreau (1817–1862)
