| 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.
