  • Patent number: 4452410
    Abstract: An aircraft containing aerodynamic and gyroscopic stability that has a high angle of take-off and landing capabilities, with high speed horizontal powered flight, but is also able to sustain power-off flight with auto-rotation of its multiple extending airfoils. The fuselage has the shape of an inverted saucer with aerodynamic configuration and has an open circular track at its periphery; and riding in this track is a rotary frame and extended airfoil assembly that isin-line with the fuselage. Each extending airfoil contains solid weighted bodies at their tips and this rotary frame and extended airfoil assembly is rotated on the track by an internal power unit. The extending airfoils taper toward their tips and these tips have a knife sharp edge for penetrating the air resistance.

  • Patent number: 4157632
    Abstract: An aerodynamic toy having a series of small extended airfoils contiguous to one another, forming a large unitary aerodynamic body, whose lift surfaces has disposed a number of small depressions. Most of the body's weight is distributed in the small extended airfoils, with placement of blind holes for the addition of extra weight. The lower surface is substantially flat at the periphery and then becomes concaved shaped. The concaved surface contains a hollow tube that holds fluid and has a dispenser at the lower end for dispersing of the fluid.
