The present invention relates to a long-range artillery shell (1) that is
fin-stabilised in its trajectory and which is designed to be fired in a
rifled gun barrel and thus has a slipping driving band (8) as main contact
surface with the inside of the barrel, and has a so-called base-bleed unit
(3) with a number of stabilization fins (9-14) that are deployable after
the shell has left the barrel. A special feature of the shell (1) as
claimed in the present invention is that the fins (9-14), when activated,
are radially displaceable to project outside the external periphery of the
shell through slots or through-holes (28) in the wall of the shell, but
are initially radially retracted inside the propellant motor section or
propellant chamber (4) of the base-bleed unit (3) between dedicated
protective walls (16-17) that isolate the fins from the surrounding
propelling charges (25) of the propellant motor and also divide the inside
of the propellant motor (4) into sectors (18-23) that are separated from
each other.
