You probably think you understand what makes a wing stall, don't you? Well, think again. Can you explain why the wing seems to lose all its lift suddenly, even though a graph of lift vs. angle of attack would seem to suggest it shouldn't? Or why the sudden stall you experience in a real airplane doesn't happen to a wing mounted in a wind tunnel? AVweb's Roger Long explains these phenomena and more, exploring such facets as airflow separation, wing camber, boundary layer, laminar flow, coefficient of lift, and wingtip dynamics. The graphics that illustrate Roger's article (including several animations) are alone worth the price of admission.
