레오나르도 다빈치 비행기구의 디자인 요소 연구

Leonardo da Vinci is considered one of the greatest thinkers in history, with interests and talents in many disciplines-art, architecture, science, engineering, anatomy, optics, aerodynamics and so on. He was a keen observer upon the nature, and tried to step beyond the primary mode of seeking knowledge-studying the ancient Greeks. With infinite curiosity, Leonardo sought answers by means of careful observation, reasoning and experiment. His notebooks, so called Codex, are where Leonardo had recorded his own ideas as well as existing designs and philosophies as references. Only about 7,000 pages are still remained from the thirteen thousands original copy of Leonardo's 'mirror writing'. Within Codex, he had exploited what it could be created in the future, when it takes actual experiments. Many insights from him have foreshadowed over scientific research in many centuries. Especially, his insightful achievement about the flight of a bird and human flying influenced on the modern science to a great extent. Indeed, Leonardo foresaw the appearance of airplane prior to 500 years of the modern aviation history. The aim of this paper is understanding the concepts in Leonardo's flying machines, and organizing his design characteristics. By analyzing design ideas and concepts on his 14 flying machines, this paper will present seven design factors - design originality, convergence of form and function, ergonomic design, aerodynamic design, bionic design, design innovation and materials used.
