Abstract

A projectile and launcher combination, in which the launcher is formed with a tubular passage having a convergently tapered inner end. A projectile element is provided at its back end with a plurality of rearwardly extending, cantilever mounted resilient leaf spring elements arranged to be received in and displaced radially inward by the convergently tapered portion of the tubular passage. When the projectile is loaded into the launcher, the leaf spring elements tend to eject it forwardly. A retention arrangement is provided to hold the projectile until it is ready to be ejected. When the projectile is released from retention, the outward pressure of the leaf spring elements on the convergent walls forcibly ejects the projectile from the launcher passage.
