Abstract
A launcher is configured to launch a plurality of ring airfoil projectiles. The launcher includes a body defining a launch passage. Ring airfoil projectiles are mounted on a magazine loaded into a first end of the passage. Movement of a trigger causes the magazine to be moved forward in the passage into engagement with a drive element, such as a pair of drive disks. Movement of the trigger also causes the drive element to be driven, and when engaged with a ring airfoil projectile on the magazine, to be launched from the second end of the passage. In one embodiment, the drive disks are driven by an electric motor and impart both a propelling and spinning force upon the ring airfoil projectile. Multiple ring airfoil projectiles may be loaded on the magazine and launched in succession without the need to reload.
