ملاحة جوية: الفرق بين النسختين

When people started to scientifically study how to fly, people began to understand the basics of air and aerodynamics. One of the earliest scientists to study aeronautics was [[Ibn Firnas]] who studied the dynamism of flying and carried out a number of experiments in 8th century in [[Córdoba, Spain|Cordoba]], [[Al-Andalus]].<ref name=Aramco>[http://www.saudiaramcoworld.com/issue/196401/first.flights.htm First Flights], ''[[Saudi Aramco World]]'', January-February 1964, p. 8-9.</ref> [[Roger Bacon]] and [[Leonardo da Vinci]] were some of the first modern Europeans to study aeronautics. Leonardo studied the flight of birds in developing engineering schematics for some of the earliest flying machines in the late fifteenth century AD. His schematics, however, such as the ornithopter ultimately failed as practical aircraft. The flapping machines that he designed were either too small to generate sufficient lift, or too heavy for a human to operate. Although the ornithopter continues to be of interest to hobbyists, it was replaced by the glider in the 19th century.
