Italian Renaissance genius Leonardo da vinci did. However, he sketched aircraft (namely helicopters) and not necessariy airplanes. Hope this helps!
Leonardo da Vinci sketched a wide variety of subjects, including anatomical studies, flying machines, and detailed designs for various inventions. His famous sketches include the Vitruvian Man, which illustrates the proportions of the human body, and numerous studies of human anatomy. He also sketched designs for war machines and architectural ideas, showcasing his diverse interests and innovative thinking.
The paper airplane website offers features for creating and sharing unique paper airplane designs, including customizable templates, design tools, and the ability to share designs with others online.
Some inventions that did not come out of Edison's laboratory at Menlo Park include the telephone (invented by Alexander Graham Bell), the airplane (invented by the Wright brothers), and the light bulb (although Edison improved upon existing designs).
The Wright Brothers (Orville and Wilbur) made the first controlled, powered and sustained flight on 17 December 1903. This is not the date the airplane was 'invented' but, until one actually flew, the inventions were just a bunch of designs. The completion of any invention lies in the production of a working example.
Sketched designs of machines not made for at least a hundred years like the paraglider and tank, as well as many others
No, patents only pertain to inventions. "Copyright", on the other hand, protects creative works of original expression, including greeting card designs. Copyright in over 160 countries is free, instantaneous and automatic. If there are inventions included in the greeting card, such as a music player or a recording device, then that portion might be protected by a patent in addition to the copyright of the artistic and literary portions of the card.
Thousands of paper airplane glider designs exist. See related links for examples.
Paper airplanes are great fun to make and children are often just as goos at adults at making them. One of the better sites for designs for paper airplanes is that of Alex Schultz which contains many paper airplane designs.
No, it is an example of a model
The Crusaders brought back many new ideas and inventions and things such as spices, architectural designs and much more including construction skills and ideas from the muslims that were in palestine at the time
leonardo was secretive about his inventions because he feared that other artists or engineers may copy his designs. That's the reason why most of his sketches or drawings are wrong so that no one could duplicate his designs. Another reason was that leonardo knew that with his inventions mankind would take a destructive turn. There would be bloodshed during wars, and he didn't want his inventions to be a part of it.
