A drive and steering arrangement according to any of the preceding claims, wherein at least one torsion angle (α, β) is reduced in the aft direction to 0° within a range defined by the respective leading edge (12, 13) and the central axis (P) of the rudder (10; 10').
5. Raspored pogona i upravljanja prema bilo kojem od prethodnih zahtjeva, gdje se tijelo u obliku žarulje (20) nalazi na lopatici kormila (10a) na kormilu (10; 10') kako bi se omogućilo njihanje tijela u obliku žarulje (20) u odnosu na izglađivanje (6) kada se lopatica kormila (10a) okrene. 5. A drive and control arrangement according to any one of the preceding claims, wherein the bulb-shaped body (20) is located on a rudder blade (10a) on the rudder (10; 10') to allow the bulb-shaped body (20) to oscillate in relative to the smoothing (6) when the rudder blade (10a) turns.
