๐ซnegative pressure on the upper surface creates a relatively larger force on the wing than is caused by the positive pressure resulting from the air striking the lower wing surface
๐ซPictures show the pressure distribution along an airfoil at three different angles of attack
๐ซaverage of the pressure variation for any given AOA is referred to as the center of pressure (CP) or in other words, the center of pressure is the point where the total sum of a pressure field acts on a body
๐ซ️Aerodynamic force acts through this CP
๐ซ️At high angles of attack, the CP moves forward, while at low angles of attack the CP moves aft
๐ซIn the design of wing structures, this CP travel is very important, since it affects the position of the air loads imposed on the wing structure in both low and high AOA conditions
๐ซairplane’s aerodynamic balance and controllability are governed by changes in the CP
