ABSTRACT:
A craft for ground effect and aerodynamic flight has, in addition to the usual vertical and horizontal stabilizer(s), a primary, upper airfoil, a lower secondary airfoil and a pivotable flap. The upper surface of the primary airfoil forms the primary lifting surface for aerodynamic flight while the lower surface forms, at its anterior and, an air intake for the compressors powering the craft and, to the rear, the upper surface of a plenum for ground effect flight. The upper surface of the secondary airfoil forms the lower surface of the compressor air intake at its anterior end and a compressed air exhaust at its other end. The lower surface forms the anterior end of the plenum when the pivotable flap is in the down position. The pivotable flap is attached near the forward end of the lower surface of the secondary airfoil to block the flow of compressed gases out the front of the craft during landing and while in hovercraft mode. Preferred models have a vertical stabilizer forward of the cockpit.
