ABSTRACT:
An aircraft is disclosed having a jet engine whose exhaust stream flow rearwardly from above the trailing edge of a main wing of the craft, and having an auxiliary airfoil which is lower than and offset rearwardly with respect to the wing and acts during takeoff to augment thrust and lift, and during braking and landing to increase drag and lift. The airfoil is mounted for adjusting movement between a cruise position in which it is generally parallel to but lower than and spaced from the wing and one or more inclined positions for takeoff, landing and braking in which the airfoil has its leading edge spaced rearwardly and downwardly from the trailing edge of the wing and defines with that trailing edge a gap across which the jet engine exhaust stream flows in a relation drawing air through the gap from under the wing.
