BALLISTIC PROJECTILE WITH EXTENDABLE FINS |
摘要 |
A ballistic artillery projectile has extensible fins (1) for stabilizing the trajectory in the terminal phase, after an initial spin being imposed on firing. The fins (1) are attached to the projectile (2) by means of torsion bar pivots (3) designed to be twisted on extension of the fins (1) by centrifugal forces, so as to undergo plastic deformation.
<??>The fin attachment is intended to render harmless impact forces when the fins (1) hit a stop and locking device in their extended position. |
