PROJECTILE IN THE FORM OF A HOLLOW TUBE, HAVING INTERNAL ELEVATIONS OR RECESSES OR COMBINATIONS THEREOF, SUCH THAT AIR FLOWING THROUGH SETS THE PROJECTILE IN ROTATION

摘要

The invention describes a tubular projectile which is suitable for being fired in particular by bows or crossbows (such as bolts and arrows), but can also be fired from other shooting devices (for example firearms). The arrow is set in rotation about its longitudinal axis by the air passing through after being fired. The rotation is achieved by elevations or recesses applied to the inner surface, which are primarily designed in a linear manner and, by interaction with the air passing through, create a trajectory-stabilizing rotation of the rod or hollow tube. To this end, the arrow generally requires no or less fletching or other elements that stabilize the trajectory.
