Discovery of Leonardo da Vinci


Discovery of Leonardo da Vinci

Da Vinci’s Machines: Air Screw
发现达文西之机器篇:单螺旋桨


Da Vinci was an Italian Renaissance polymath. He played several roles in his life such as painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist and writer. Genius is the best word can be used in described Da Vinci. He contributed a lot to people. Some of the scientists and inventors are doing research based on his manuscript.


Do you know that why helicopter can fly? The idea was from Da Vinci. In his mind, he always thinks that one day people can fly like the bird. 1480, he sketched air screw and try to make it fly. He failed to make it. In 1910, his sketch was read by a young man. The man did research on it. Finally he managed to create the air screw of the helicopter.


Based on the manuscript of Da Vinci, he stated that the material for making the wings must be tough and tensile and there will be no hole. In short, he was concerned about the types of materials which being used.

There is a group of experts did study on it. They try to make the air screw can be functioning via the new technology and some lighter material in making the pillar and the wing. There are six people involved in this mission. They are Terry Sandin, Dr Jonathan Pevsner, Flash Hopkins, Valek Sykes, Bill Duggan and Juan. Terry is a mechanical engineer who is the expert of electronic and small robot. Dr Jonathan is Leonardo expert, Flash is a builder, Valek is special effects expert, Bill is a carpenter and Juan is ultralight expert.


In short, Da Vinci was a great people.


Due to my curiosity I make an air screw to study on it. I would like to know why the original design of air screw can’t fly. After I have done, I come out which some reasons based on my own understanding.



Based on my own understanding, I think the problem is come from the design of the wing and the size of the pillar. I think the numbers of the wings should be reduced. So the mass of the wings can be reduced. That is just my own point of view.

Here are some of the pictures of my own air screw.
