FAQ:
could you make a sizable aircraft powered by an aerial screw (pic included)?
using modern materials and devices, could the aerial screw concept that Leonardo da Vinci thought up be used to power a helicopter-sized, 1300-to-1800 pound machine? Is the concept simply not capable of powering something that heavy, no matter its size and strength? How fast, and how big would an aerial screw have to be to make this work?
Answer by Pilsner Man
pic lost, can’t make a determination.
But to answer your question, no I couldn’t.

The aerial screw designed by DaVinci would not generate lift, regardless of it’s size. It is not an aerodynamically sound design and not capable of producing lift. And,since air is not a solid medium (like wood or plastic) the screw would not have any surface on witch move itself along as it rotates.
