He did build a working model of one.
It was not built then, but Leonardo da Vinci made a drawing of a helicopter in the 15th Century.
Leonardo da Vinci had a very imaginative mind. He drew many pictures but never built any of the things he drew.
Leonardo da Vinci was approximately 31 years old when he built his 'Aerial Screw'
I think he built it with the help of his uncle. It was a model made perhaps by looking at maple seeds falling. Look at the link below:
Nothing that was actually built..
In 1901 at the age of 16, he built a working model of a helicopter.
Leonardo da Vinci conceptualized the airscrew around 1485, as part of his studies on flight. He designed a device resembling a modern helicopter, which he called the "air screw." Although it was never built or flown during his lifetime, his sketches and ideas laid foundational concepts for future aeronautical engineering.
It was never actually built.
The aerial screw, an early helicopter design, was invented by Leonardo da Vinci around the late 15th century. However, it was never actually built or flown during his lifetime.
Leonardo Da Vinci was a artist and a builder.he painted the "Mona Lisa" and "The Last Supper." He built a GIANT bronze horse for the king. Your Welcome<3 lol
Like most of Leonardo's original ideas it was never built.
