Abstract: A human free-flight launcher including a seat positioned within a tetrahedral frame and supported therein by elasticized cords which, upon retraction of the seat within the interior of the tetrahedral support frame, come under tension to cause the seat, upon its release, to be propelled forward launching the person seated therein into free-flight through an open face of the tetrahedral support frame.

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.

Abstract: A wingless aircraft having a power channel with two parallel ducts afixed to the top of the fuselage. A jet engine or other drive mechanism is positioned within each duct. No air flow is permitted between any part of the lower surface of the power channel and the fuselage. Each duct contains a number of variable-pitch airfoils that are independently adjustable. This independence of adjustment between variable-pitch airfoils within a single duct and the ability to adjust the variable-pitch airfoils in one duct as a group independently of those in another duct provides horizontal stability and compensates for undesired yawing. The lift is controlled to somewhat by adjustment of the variable-pitch airfoils and the angle of attack, and to an even greater extent in cooperation with adjustable auxiliary wing panels mounted above openings in the upper surface of each duct above one of the variable-pitch airfoils. The auxiliary wing panels nest in openings above the airfoils when not in use.
