ABSTRACT:
Toys and methods for safely and reproducibly launching ring airfoils in a flying orientation. The toys generally comprise a member, a ring airfoil support mounted on the member, and a propelling element configured to move the ring airfoil support along the member from a first to a second position. Contact between the ring airfoil and the ring airfoil support causes the ring airfoil to move with the ring airfoil support as the ring airfoil support moves; this contact is overcome as the ring airfoil support decelerates at the second position, causing the ring airfoil to be launched with forward or both forward and spinning motion. The toys further may comprise a housing to protect the toy and user, a return element to place the toy in an engaged, launch-ready configuration, and a trigger to hold the toy in the engaged configuration until launching. As an additional aspect of the invention, components of the device may be chosen so that the characteristics of the ring airfoil at launch are within certain safety limitations.
