Abstract

A training projectile which is stabilized by its own rotation during flight is described and comprises a conical nose section (1), a cylindrical intermediate portion (2) and a tail section. The projectile is provided with aerodynamic surfaces in the form of fins (4) or grooves (8) (not shown) on the cylindrical intermediate portion (2). The fins and grooves, respectively, extend substantially radial and parallel to the symmetrical axis (5) of the projectile. The arrangement of said fins or grooves imparts a braking effect on the projectile to reduce its rotational velocity after launching so that the projectile at a specific, critical rotational speed becomes unstable and tips or tilts. This means a substantial increase of air resistance and a corresponding reduction of the projectile velocity forwards. By an appropriate adjustment of the fins (4) and grooves (8) respectively, it is possible to locate the instability just behind the target distance when training. The ballistic properties of the training projectile are maintained up to the target distance but the maximum firing range is reduced compared with the normal live ammunition. <IMAGE>
