Aerodynamic forces acting on a wing.

  Aerodynamic forces acting on a wing. While a lot has been discovered about why a paraglider flies, a lot remains unknown too (To me, but i know people who know everything).  Like every aircraft, a paraglider has its own uniqueness. It's made of cloth and lines with no hard structure. The pilot hangs far below the wing, like a swing. It can fly backwards commonly known as tailslide . It can do spiral dives facing the ground and can tumble, it can Helico (spin on its vertical axis) and can change the center of rotation from outside in a spiral dive to inside in a SAT . Even the best engineers struggle to explain everything but fortunately there is a lot known too. Firstly, we know the broad shape of an aerofoil. When that shape moves through air, some air flows over it and some under it. We named the point at which airflow splits as Stagnation point. DIAGRAM 1  Then we drew a line from the stagnation point to the trailing edge and called it Chord. We now put some wei...
