Ornithopter
The Human-Power Ornithopter, a wing-flapping device, was designed in 1485 with the intent to fly. However, there is no evidence that he attempted to build the machine, but his ideas of human powered flight device followed for the next several hundred years. His inspiration came from birds or bats, which lead to the two-wing device feature. The wingspan exceeded 33 feet and the frame consisted of pine covered in raw silk, which is light but sturdy. The pilot, laying down in the center of a board, would pedal a crank connected to a rod-pulley system. To increase energy output, the pilot had a hand crank. In addition, the pilot had a head piece for steering. The pilot must have been really busy! This all allows the wings to flap …show more content…
He thought centuries ahead of his time; the actual helicopter took flight 450 years later. Once again, he never built or tested it, but wrote detailed notes and drawings that demonstrated exactly how the device should function. His inspiration probably came from studying the seeds of the Maple Tree. Personally, I remember being fascinated as a little kid with these seeds. My brother and I would throw them in the air and watch them spiral, trying to catch them before they hit the ground. So what would happen if the seed could rise when …show more content…

"If a man have a tent made of linen of which the apertures (openings) have all been stopped up, and it be twelve braccia (about 23 feet) across and twelve in depth, he will be able to throw himself down from any great height without suffering any injury."
Uniquely, the canopy was triangular rather than rounded. His idea was made out of linen covering a wooden frame, so the weight would probably prevent the parachute from working. Like his other inventions, the parachute was never tested or built.
However, in 2000, a daredevil Adrian Nicholas built a prototype based on da Vinci’s notes. The design worked and Nicholas even stated that the ride was smoother than the modern parachute. Nicholas dropped 3000 meters from a hot air balloon, ignoring expert advice that his canvas and contraption would not fly (it weighs 187 lbs). It was so heavy because it was built out of materials available to the medieval Milan and built using tools from the time period. Nicholas freed himself from the device at 2000 feet to ensure that the heavy device did not crash down upon him at
