Airfoil Hats
Description: A schematic depicts an airfoil interacting with undisturbed flow, showing air deflecting upwards and downwards. Below, a formula and two rows of graphs illustrate fluid dynamics, featuring spheres with swirling blue arrows and contour plots with flow lines and numerical axes.

Description: This design features an airfoil or a wing section and its pressure contour. It is a characteristic image from the world of aerodynamics, fluid dynamics, and aerospace engineering. Computers can help simulate the fluid's behaviour around and airfoil but extensive validation is required throguh wind tunnel experiments.
Description: A black background displays a diagram illustrating aerodynamic principles. A gray airfoil shape is shown with blue arrows indicating airflow. Text labels identify 'LOW PRESSURE AREA' above the airfoil and 'POSITIVE PRESSURE AREA' below. A red arrow labeled 'LIFT VACUUM' points upwards.
Description: 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.
