Aerial Screw
The Aerial Screw design is a precursor
of the modern day helicopter.
The drawing of Da Vinci’s concept
illustrated the compression of air
that was intended to lift
the upper part (propeller or screw)
the device off the ground.
Mechanical Drum
Leonardo da Vinci’s mechanical drum was
designed as a cart equipped with an amply
sized drum. When pulled by its handle,
the gears turn the two lateral drums,
which are fitted with pegs. The pegs move
a total of ten drumsticks that cause
them to beat the large drum.
