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,
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.

1. Control group for directional fins on missiles or shells comprising a containment body (15, 15', 15") carrying on the outside two command surfaces in the form of half-fin surfaces (13, 14) which are hinged (at 24, 25), directable and motorized, characterized in that said containment body (15, 15'
1. Control group for directional fins on missiles or shells comprising a containment body (15, 15', 15") carrying on the outside two command surfaces in the form of half-fin surfaces (13, 14) which are hinged (at 24, 25), directable and motorized, characterized in that said containment body (15, 15', 15") has two housings (16) each of which received an electric motor (17, 17') which commands, oscillation about an axis (Z) of said reduction gear group, of through a reduction gear group (19, 29; 19', 29'), a pair of rings (21, 22), arranged in first annular seats (31, 32) and in which end attachments (26) of said half-fins (13, 14) engage, said half-fins (13, 14) being hinged diametrically opposed in a further ring (20) arranged in second annular seat (23) of said containment body (15, 15', 15") said half-fins being free to rotate about said axis (Z). 2. Control group according to claim 1, characterised in that each of said rings (21, 22) has a localised groove (27) to receive an end attachment (26) of one (13 or 14) of said half-fins (13, 14) and a groove (28) formed along at least a quarter of the circumference of said ring which is of a depth little greater than that of an attachment (26) which receives an attachment of the other (14, 13) of said half-fins (13, 14), said groove (28) of a ring (21 or 22) facing the localised groove (27) of the other ring (22 or 21). 3. Control group according to claim 2,characterised in that said localised groove (27) of one ring (21 or 22) faces towards the other ring (22 or 21) inserted into said groove (28). 4. Control group according to claim 1, characterised in that said reduction gear group associated with said electric motor (17, 17') comprises sprockets (19, 29; 19', 29') which engage by means of a reduction gear in a toothing (30, 30') formed internally on each of said two rings (21, 22). 5. Control group according to claim 4, characterized in that said reduction gear is a toothed reduction gear which comprises a spindle (36) carrying a pair of sprockets, with different diameters and fitted onto said spindle, a first sprocket which engages with a sprocket (19, 19') that is integral with said motor (17, 17') and the second sprocket engaging with said toothing (30, 30') that is formed internally on respective rings (21, 22), said spindle (36) being supported on two separate portions (15',15") of said containment body (15). 6. Control group according to claim 1, characterised in that each of said half-fins (13, 14) foresees a pivoted extension (24), fastened through axial locking elements (25), but free to rotate, in said further ring (20), said two half-fins (13, 14) being arranged at 180° from each other. 7. Control group according to claim 1, characterised in that said containment body comprises three separate portions (15, 15', 15"), fastened together through stable fastening means (33), said grooved annular seats (31, 32, 23) are located within said three separate portions. 8. Control group according to claim 1, characterised in that each of said half-fins (13, 14) foresees, in a rear part thereof, a small radial extension (34), facing towards the inside of said containment body (15, 15', 15"), which engages in a curved slot (35) formed in an extension (20') of the further ring (20). 9. Control group according to claim 1, characterised in that each of said pairs of rings (21, 22), arranged in the annular seats (31, 32), have a surface and perimetric extension (21', 22') which is housed in a perimetric surface extension of said annular seats (31, 32).
