Abstract
This disclosure relates to a method of limiting the yawing motion on the trajectory of an artillery shell during the firing phase using a sliding driving band and completely folded-in guide fins. The shell is converted as soon as possible outside the mouth of the barrel of the firing piece by fold-out of the guide fins into a fin-stabilized artillery shell. Any form of non-uniform fin fold-out is avoided by virtue of all the guide fins being interconnected to form a system which gives all the fins the same movement pattern and the same fold-out speed in each phase of fin fold-out. This disclosure also includes a shell in which synchronization of fin fold-out includes a rotatable control ring that is arranged around the axis of the shell and is connected to the rotation spindles of all the fins.
