A fixed wing aircraft that can be automatically and rapidly converted to a roadway vehicle within seconds while driving in the highway, comprising a one-piece wing rotatably mounted on top of the fuselage. The aircraft features a 3-horizontal-surface design allowing good pitch stability and damping in a very short fuselage, stall-resistant feature and reduction in induced drag at cruise speed. The aircraft's wing is enlargeable with additional wing tip segments allowing boost in aspect ratio hence improving efficiency at high loads. The vehicle has low center of gravity, four wheels with independent suspension, nose-height leveling for take-off and landing, and anti-sway mechanism in order to prevent roll-over in a tight turn. Ground propulsion is by both a ducted fan and hydraulic rear wheel drive allowing rapid accleration in the roadable mode.

[ What is claimed is:] [1.] In a roadable flying vehicle designed to operate effectively both in the air and in the roadway, said vehicle having a monoplane wing with a span, a fuselage with a length significantly shorter than the span of said wing, a cabin with a cockpit for housing an operator, a center of gravity, a longitudinal axis, a width, a top, a front end, two lateral sides, and a rear end, the combination comprising:ground-supporting means comprising of front ground-supporting means disposed at the front end of the vehicle and rear ground-supporting means mounted behind the center of gravity, said ground-supporting means having road wheels in contact with a supporting surface, on each lateral side of the vehicle,a vertical stabilizer means located at the rear end of the fuselage,a horizontal stabilizer means located on at least one end of the fuselage,an air propulsion means for propelling said vehicle while flying in the air,a ground propulsion means for moving said vehicle while rolling in the roadway,said monoplane wing having a wing span significantly longer than the length of said fuselage, for providing a majority of vertical lifting force to the vehicle, said wing is rotatably mounted on top of said fuselage on a wing pivot mechanism whereby said wing is horizontally rotatable between a flight position with the wing span approximately orthogonal to the fuselage's longitudinal axis and a roadable position with the wing span approximately parallel to the longitudinal axis of the fuselage, thereby allowing the vehicle to have a maximum width within legal limit for use in the roadway but potentially blocking upward vision from the vehicle's cockpit, hence,means for providing adequate upward vision from the vehicle's cockpit in the roadable position, thereby allowing the vehicle's operator to see high-mounted traffic signal lights and road signs mounted on highway overpass, said means for providing adequate upward vision from the vehicle's cockpit in the roadable position is comprised of:rearward disposition for the air propulsion means of the vehicle, thereby bringing the center of gravity of the vehicle toward a rear end of the cabin,a horizontally-oriented elongated surface disposed significantly in front of the wing for providing upward-lifting force to the vehicle significantly in front of the center of gravity, thereby allowing said wing to be mounted in a rearward position with respect to the center of gravity, and whereas,said wing is further comprised of:a center section having a sufficiently short span for use in the roadable position, thereby, in combination with the rearward wing mounting position, allowing for sufficient clearance for adequate upward vision from the cockpit,a pair of wing tip segments for extending the span of said wing for use in the flight position,extension means capable of extending said pair of wing tip segments laterally from said wing center section thereby increasing the vertical lifting force and efficiency of the wing in the flight position, and,sealing means disposed between the fuselage and the wing, said sealing means is capable of effectively sealing potential gap between said wing and said fuselage in both the flight position and the roadable position.
