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.
