Abstract:
A ring airfoil launcher comprising:a barrel;a launch spring disposed within the barrel;a rod disposed within the barrel and coupled to the launch spring, the rod being axially slidable within the barrel between a first position and a second position, wherein in the second position energy is stored in the launch spring and in the first position energy is released from the launch spring;a chuck, the chuck being coupled to the rod for movement therewith and the chuck being coupled to a contoured surface formed in the barrel, the contoured surface being arranged to impart a rotational motion to the chuck;a first ring airfoil engaging surface formed on the chuck, the first ring airfoil engaging surface being adapted to engage an inner diameter of a first ring airfoil; anda second ring airfoil engaging surface formed on the chuck, the second ring airfoil engaging surface being adapted to engage an inner diameter of a second ring airfoil.
