Abstract: Control group for directional fins on missiles and/or shells which have a containment body (15, 15′, 15″) that has on the outside of the containment body, two command surfaces in the form of half-fin surfaces (13, 14) which are hinged (at 24, 25), directable and motorized. The containment body (15, 15′, 15″) has two housings (16) each of which has an electric motor (17, 17′) which commands, through a reduction gear group (19, 29; 19′, 29′), the oscillation about the axis (Z) of a control group that is based on a pair of rings (21, 22), arranged in annular seats (31, 32) and in which end attachments (26) of the half-fins (13, 14) engage, the half-fins (13, 14) being hinged so that they are diametrically opposed in a further ring (20) arranged in an annular seat (23) of said containment body (15, 15′, 15″) where they are free to rotate about the (Z) axis.

Abstract: A control group for directional fins on missiles and/or shells comprises a containment body (15, 15′, 15″) carrying on the outside two command surfaces in the form of fin or half-fin surfaces (13, 14) which are hinged (at 24, 25), directable and motorized, in which the containment body (15, 15′, 15″) foresees two housings (16) each of which receives an electric motor (17, 17″) which commands, through a gear-dowm group (19, 29; 19′, 29′), the oscillation about an axis (Z) of the control group of a pair of rings (21, 22), arranged in annular seats (31, 32) and in which end attachments (26) of the half-fins (13, 14) engage, the half-fins (13, 14) being hinged diametrally opposed in a further ring (20) arranged in an annular seat (23) of the containment body (15, 15′, 15″) free to rotate about the axis (Z).
