Title
(EN) Ballistic artillery projectile, that is initially spin-stabilized
Abstract
(EN)

A ballistic artillery projectile that is initially spin stabilized and is provided with fins that are extended after the projectile has covered a part of its trajectory. The fins are attached to the body of the projectile by means of bars that are non-rotatably engaged with the fins and the projectile, and that have portions between the fins and the projectile that are designed to be deformed by torsion when the fins are being extended.
