Leonardo
da Vinci turned his skills to many topics. The diagram shows a wing design
for a human powered craft, probably an ornithopter, sketched in about 1485.
The flapping mechanism seems to be actuated by a hand crank and the wing design
has a cambered surface, as do those of birds. Although recorded in his
manuscripts, scientific publication was not a strong component of Leonardo's
scientific contributions. The ornithopter concept was also a poor one with
which to attempt human-powered flight. |
