  • Patent number: 4634080
    Abstract: The invention is an improved method and device for utilizing the principles of lift achieved through the dynamic physics of the airfoil. In the case of the present invention, the airfoil utilized is a parafoil. The parafoil of the present invention is a multi-layered or multi-tiered arrangement to provide an improved directly vertical lift without the less efficient angular lift of the common parafoil horizontal dispersement of lifting power. The present parafoil vertical lift mechanism consists of a plurality of parafoils assembled in a multi-layered vertical configuration, a plurality of positioning stabilization rods to maintain the basic vertical spacing of the plurality of parafoils for an immediate ballooning effect at the start for take-off, a lifting frame suitably affixed to the assembled plurality of parafoils, a plurality of stabilization tether lines, at least one counter-drag tie line, and a load connector for suitably removably affixing the load to be lifted to the lifting frame.
