Leonardo da Vinci, His Contributions to Modern-Day Flight

I have to do a project on him now -_-

he also invented the hidden blade, a weapon used back in the rennissance for assassination and protection.

no he really didnt that was just a plot thaqt assassins creed used to put the blade in a game

Airplanes with symmetric (top/bottom) wings are perfectly capable of flying; that's why they can fly upside down. However, since they lack the curvature, they are not as efficient.

They aren't neccesarily less efficient, but since the pressure distribution around the profile is symmetric, it needs an angle of attack to create a pressure difference which results in lift....

Very nice video. Next time, allow the voice of the woman to go on even when you show pictures; it will help the video/documentary to become a whole piece, without interruption. This technique is used in pretty much every documentary. Again, good job over all.

onixya, thanks for the comments. This video was one of the first videos I made, plus with a low-quality vid. camera. I've learned a great deal about filming over the year. I'll be putting up another vid about Leonardo in the future.

In 875, aged 70, having perfected a machine of silk and eagles' feathers he tried again, jumping from a mountain. He flew to a significant height and stayed aloft for ten minutes but crashed on landing - concluding, correctly, that it was because he had not given his device a tail so it would stall on landing. Baghdad international airport and a crater on the Moon are named after him.

A thousand years before the Wright brothers a Muslim poet, astronomer, musician and engineer named Abbas ibn Firnas made several attempts to construct a flying machine. In 852 he jumped from the minaret of the Grand Mosque in Cordoba using a loose cloak stiffened with wooden struts. He hoped to glide like a bird. He didn't. But the cloak slowed his fall, creating what is thought to be the first parachute, and leaving him with only minor injuries.
