An airfoil segment for inclusion in an aircraft wing is provided. The multi-element slotted airfoil segment has at least one propeller operatively located in a slot communicating therethrough for improved low speed performance and control. Upstream propeller flow field effects generated allow the front portion of the airfoil segment to be structurally efficient thicker airfoils with higher lift-to-drag laminar airfoils or higher maximum lift coefficient designs. The downstream propeller flow field acting on the aft portion of the airfoil segment increases lift and allows flaps on the aft portion to provide control forces/moments at static or low flight speeds for short or vertical take-off.
