Everyone has seen at once?
Leonardo da Vinci's "Aerial screw"
Or it may be able to be called the prototype of a helicopter.
According to Mr. da Vinci's description,it is the structure of attaching spiral wings to a shaft and rotating it by four persons.
It is proved that it does not fly theoretically. But I do not understand at all.
Even so, da vinci is genius.
