Great Kite
The Great Kite () was a wooden machine designed by Leonardo da Vinci. Leonardo realized it between the end of the 15th Century and the beginning of the 16th Century. Drawings of parts and components of this machine can be found in the Codex on the flight of birds, which however lacks the overall description of the machine itself. Some drawings within the same codex suggest that it was created in similarity with flapping flight. However, this was hardly possible to perform given the available technologies, thus Leonardo developed a machine for mainly a gliding flight. The machine is named after the animal from which Leonardo took inspiration to realize the flying machine, the Kite (bird), Kite.

Codex On The Flight Of Birds
Codex on the Flight of Birds is a relatively short codex from by Leonardo da Vinci. It comprises 18 folios and measures 21 × 15 centimetres. Now held at the Royal Library of Turin, the codex begins with an examination of the flight behavior of birds and proposes mechanisms for flight by machines. Leonardo constructed a number of these machines, and attempted to launch them from a hill near Florence. However, his efforts failed. In the codex, Leonardo notes for the first time that the center of gravity of a flying bird does not coincide with its center of pressure. Summary The following summaries are from the codex whose English translation was prepared by Culturando and Smithsonian Institution. Front Page The front page is titled "On Casting Medals". The first paragraph gives a brief recipe that consists of "emery", "nitric acid", "iron filings", "vinegar", "ashes of walnut leaves", and "finely ground straw ash". The second paragraph tells of the process of crushing di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Science And Inventions Of Leonardo Da Vinci
Leonardo da Vinci (1452–1519) was an Italian polymath, regarded as the epitome of the "Renaissance Man", displaying skills in numerous diverse areas of study. Whilst most famous for his paintings such as the ''Mona Lisa'' and the ''Last Supper'', Leonardo is also renowned in the fields of civil engineering, chemistry, geology, geometry, hydrodynamics, mathematics, mechanical engineering, optics, physics, pyrotechnics, and zoology. While the full extent of his scientific studies has only become recognized in the last 150 years, during his lifetime he was employed for his engineering and skill of invention. Many of his designs, such as the movable dikes to protect Venice from invasion, proved too costly or impractical. Some of his smaller inventions entered the world of manufacturing unheralded. As an engineer, Leonardo conceived ideas vastly ahead of his own time, conceptually inventing the parachute, the helicopter, an armored fighting vehicle, the use of concentrated solar ...
