Near the speed of sound, a laminar type airfoil will lose laminisity because of the approaching transitional shockwave. The super critical airfoil defeats this by its highly swept wing shape that provides a long wing area while having a smaller lateral profile, i.e. you get larger wings and less drag in a smaller package.

Why??? Simple answer, because a normal laminar airfoil will simply be destroyed at speed close to sonic boom. Pressure is too high... Use an example to calculate it with the reynolds equation, you should not have trouble to explain it...

Try asking that in the Aircraft section of the Cars & Tansportation area. This isn't it.
