My understanding is that biplanes are pretty awful aerodynamically, the two wings interfere with each other, and the reason they persisted as long as they did was the fact that box girders are easier to make strong than cantilevered wings.
But when I learned how to sail, they told me that a ship with a mainsail and jib (a sloop) is much faster than one with just a larger mainsail, and that this was due to airflow in the slot between the two sails.
Why do stacked airfoils work for sailboats, but not aeroplanes?
