发明名称 METHOD OF SYNCHRONIZING FIN FOLD-OUT ON A FIN-STABILIZED ARTILLERY SHELL, AND AN ARTILLERY SHELL DESIGNED IN ACCORDANCE THEREWITH
摘要 The present invention relates to a method of as far as possible limiting the yawing motion on the trajectory of an artillery shell(1), provided during the firing phase with a sliding driving band and completely folded-in guide fins (3, 16), which shell, as soon as possible outside the mouth of the barrel of the firing piece, is converted, by fold-out of the guide fins (3, 16), into a fin-stabilized artillery shell, any form of non-uniform fin fold-out being avoided by virtue of all the guide fins (3, 16) being interconnected, by means (18, 19, 20) adapted thereto, to form a system which gives all the fins (3, 16) the same movement pattern and the same fold-out speed in each phase of fin fold-out. The invention also includes a shell (1) designed in accordance therewith, in which the means for synchronization of fin fold-out consists of a rotatable control ring (19) which is arranged around the axis of the shell and is connected to the rotation spindles (13) of all the fins.
