WikiAnswers How Do Airplanes Fly? by Fooling

  • The top of the wing is more curved than that of the bottom of the wing. The reasoning behind this is that the increased curvature on top of the wing will take advantage of something called magnus effect. 
  • So we know the top of the wing is more curved than the bottom. But how does that have anything to do with magnus effect? 
  • Basically, the shaping of the wing "fools" the air around it into thinking it is a long rotation cylinder, and forces the air to travel faster over the top of the wing than that of the bottom. 
  • And according to Bernoulli's Principle, faster moving air = lower pressure. If we have lower pressure on top of the wing than we do on the bottom of the wing, we now have an inequality of pressures acting on the wing. 
  • There is more pressure pushing up on the bottom of the wing than there is on the top pushing down, which means we now have a total net force pushing UP. And voila.. we have LIFT. 
This is an attempt to make sense of the Kutta-Zhukovsky circulation theory of lift, which however doesn't make sense as shown on The Secret of Flight, and so not only the air around the wing is "fooled" but also the curious reader posing the question.
