Abstract:
1. An airfoil comprising: a trailing part and a full span, bipartite flap, said bipartite flap having positions including an extreme retracted position and an extreme extended position; said bipartite flap including an inboard flap portion and an outboard flap portion; each of said inboard flap portion and said outboard flap portion including a leading part and a trailing part; said outboard flap portion including a flap member and an aileron member, said flap member having a flap member leading part and a flap member trailing part having a fixed distance therebetween; said aileron member being independently operable and pivotally mounted on said flap member trailing part, said aileron member including an aileron member leading part and an aileron member trailing part; linkage extending from airfoil support structure to said outboard flap portion to translate said outboard flap portion between at least a first and a second position to create a functional slot between a bottom surface of said flap member leading part and a bottom surface of said airfoil trailing part to draw a portion of higher pressure air from said bottom surface of said airfoil through said functional slot to distribute said higher pressure air over a top surface of said outboard flap portion; and said flap member trailing part of said outboard flap portion and all of said aileron member being located aft of said airfoil trailing part when said bipartite flap is in an extreme retracted position.
