Abstract:
1. A launcher configured to launch a ring airfoil comprising: a main support having a first end and a second end; a chuck movably mounted on said main support, said chuck comprising a conical body for accepting a ring airfoil thereon; a stop mounted on said main support, said stop limiting the movement of said chuck towards said first end of said main support; a spring biasing said chuck towards said stop; a retractor movably mounted on said main support, said retractor located distal of said chuck; at least one connector configured to selectively connect said retractor and said chuck, whereby movement of said retractor towards said second end of said main support when said retractor is connected to said chuck causes said chuck to move towards said second end, extending said spring; and a release causing said at least one connector to disengage, allowing said spring to move said chuck forwardly along said main support towards said stop, causing a ring airfoil mounted on said chuck to be released and projected off of said launcher.
