Not Exactly The V-22, But Incredibly It Was Conceived In 1943.
The experimentation that distinguished German engineering in World War II is still being felt and these aviation designers were among the most creative.
Oddly the first tilt rotor aircraft design was created by Focke Achgelis. It was called the Fa .269. In the fifties, this would have been labeled a convertiplane, that is a car that becomes plane or a helicopter that becomes a plane or a plane that becomes something else.
The configuration was a mid-wing cantilever monoplane with a nuanced sweep back wing, a standard pair of rear horizontal stabilizers and a single rear rudder.
Two engines powered very-large-diameter pusher propellers. For take-off and landing they would have swiveled forward and groundward at 85°.
The entire gearing, swivel mountings, interlocking systems and pitch control would have to be developed. It wasn’t. This was seen as so dangerous and so costly that no prototype was built.
