Leonardo da Vinci (1452 – 1519) is most famous as an
outstanding artist, but was also a scientist. During 1483-99 he found
employment at Ludovico il Moro (Sforza) in Milan. Here he spent as much
time with fortification- and engineering projects as with architecture and
arts. During these years he also made his most important investigations to
the problems of flight.
Most of his work concerned ornithopters - flapping-wing flying machines
imitating the flight of birds and bats. The major part of his designs was
prone-positions types – the perhaps most famous is seen below. Leonardo
was aware of man’s limited muscle force. His sketches show aircrafts where
the pilot is working with both arms and legs to operate his aircraft. But
this was not enough. His constructions would never fly. He made some
successful tries with a light hang glider, but unfortunately never
fulfilled it.
The picture below shows Leonardo’s own sketch of the inner mechanism of
the ornithopter. The picture at bottom gives an impression of the complete
ornithopter with wings etc. fitted (based on an image at NASA’s website –
thanks NASA!). |
