Designing Super-critical Foils

I've seen airfoils where the highest velocity over the wing isn't at one point, it almost appears to be equally distributed across the top of the foil. Is the primary intent to have the highest coefficient and the highest subsonic mach before a shockwave forms on the wing? I have been trying to mode...

Oblique Wings -- Yaw Tendency?

Swept back wings and straight wings have tip-ward flowing induced flows (swirls at the tips) which results in induced drag. Swept forward wings have their flows moving inward and as a result, little if any induced drag. Concerning aircraft with oblique wings, would the combination of forward and rea...
