O due to geometry of airfoil the velocity and therefore the pressure vary manifestation of lift o it is convenient to express this as a pressure coefficient c p p pf qf o from bernoulli eq and assuming density is constant ok for m 03 c p 1 v vf2 o pick out some features on figure at left lift proportional to .

This primer talks about why we have wings at all as the aerodynamicist jack moran said wings are simply a thrust amplifier sure we could use rockets to get from point a to point b but that would be incredibly inefficient as far as fuel usage goes thats where wings come in. For our purposes all airfoil diagrams shown in this primer series assume air movement from left to right lets look at an example take a symmetric airfoil and point it directly into the oncoming wind as shown in figure 1 since the airfoil is parallel with the wind we cant measure or feel any perpendicular forces up or down in this case
