ABSTRACT:
A projectile adapted to be struck by a racquet or manually thrown in a game comprises a body portion and a relatively movable extendable/retractable vane portion mounted thereon. At the commencement of flight along a trajectory, the vanes in the vane portion are set in retracted position relative to the body portion. As the flight progresses, the vanes are gradually extended by a biasing mechanism at a controlled or timed rate to cause gradually increasing aerodynamic drag, thereby unpredictably altering the flight trajectory, shortening the flight distance and reducing the speed of the projectile than would otherwise occur if the vanes had remained retracted. Such extension or transformation adds a new element of anticipation and game strategy for the contestants. The vanes are reset to the retracted position for a subsequent flight either by striking the head of the body portion with a racquet (as in the case of a racquet game) or manually (as in the case of a dart-like throwing game).
