Drag as lift in flight

Articles about drag and lift, the two forces that are used for flight and how birds actually use drag to help lift. VERY interesting!

This is another article on the same subject but I wanted to show the picture and tell you that the study used parrotlets in the tunnel. An interesting bit of trivia: it was a lovebird that first used the 'wind tunnel' when it was invented (they took Xrays of him flying through it to see how the bones moved as it flew).

Drag is always used by a wing in order to create lift. That is called induced drag. There is an inevitable drag byproduct in production of lift and it is most prevalent at high angle of attack slow flight.

On this article we learn the names of the five plets they used on the study: Gaga, Gary, Aurora, Oreo and Boy!
