ABSTRACT:
An improved auto-plane has been invented which has been adapted for air travel and road travel using a Pusher type design. The present invention auto-plane has two main wings which are cut approximately parallel to an imaginary fuselage centerline at about two-thirds the distance in from the wing's outer tip to the imaginary centerline, one of the two main wings being hinged along its cut and above its top surface at a height sufficient to allow both of the two wings to be folded inward 180.degree. with one resting atop the other. The auto-plane includes a rear stabilizer system which can be retracted forward to reduce the overall length for road use, a Pusher type propeller, and a Pusher type aviation engine which is located within the fuselage to drive the propeller. Landing wheels are located on the underside of the fuselage in an aviation landing relationship, e.g. tricycle, and aviation controls are located within the fuselage to control the aviation engine, propeller and elevons and rudders. An independent land vehicle engine is located within the fuselage and connected to drive one or more of the wheels for land use. In an alternative embodiment, each wing is cut twice, once about one-quarter the distance in and once about three-quarters in, with hinges to allow unique double (spiral) folding to permit compact stocking of the twice folded wings.
