Italian Renaissance genius Leonardo da vinci did. However, he sketched aircraft (namely helicopters) and not necessariy airplanes. Hope this helps!
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.
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
No, it is an example of a model
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.
any kind. your awsome! have a nice day
Aeronautics. This covers designs, flight characteristics, flying abilities, etc.
Airplane bodies are manufactured in two types of material- with the exception of more high-tech designs- which include aluminum and fibreglass.
Leonardo Da Vinci had several inventions. Some of these inventions included the pendulum clock and perspective. He also created designs for hot air balloons, rams, catapults, tanks, submarines, and other such machinery.
