  • Ring airfoil launching system
    Patent number: 6742509
    Abstract: An airfoil launching system having a rod with a structure attached to a first end of the rod. A pusher holds a ring airfoil and has a sufficient coefficient of friction that the ring airfoil will generally rotate with the pusher and is rotatably and slidably mounted on the rod. Propulsive force is provided by resilient bands connected to the structure outward from the rod and to the pusher outward from the central aperture of the pusher. A grip attached to the pusher is utilized to draw the pusher toward the second end of the rod, thereby stretching and energizing the resilient bands, and also to rotate the pusher and, consequently, the airfoil.
    Type: Grant
