Let it Flow Magnet

Airfoil in the wings of airplane works based on Bernoulli's principle. Airfoil designed to have more length on the top side, thus the wind that split during its collision with the airfoil needs to travel faster on the top side compared to the bottom side. This will make the pressure on the bottom side higher than the top side of the airfoil, resulted in the generation of lift force that makes the airplane fly. As the angle of airfoil increased, the void appeared on the tail of airfoil creating pressure drop on this area and the air flowing in turbulence. If this condition continues, the pressure on the front of airfoil builds up and the rear dropped, resulting in more drag force compared to the generated lift, and turning it to stall.
