Title (EN) DEVICE FOR INCREASING THE STEERING EFFECT OF A RUDDER
(FR) DISPOSITIF DESTINE A AUGMENTER L'EFFET DIRECTIONNEL D'UN GOUVERNAIL
Abstract:
(EN) Arrangement for enhancing the steering effect of ship rudders (5) comprising at least one passageway for supplying seawater from a pump to ducts (11) in the rudder, and means (20) communicating with the ducts and being adapted to discharge seawater supplied through these at the rudder surface. Said means comprise a profile element (20) extending preferably vertically at the leading edge of the rudder (5) and being pivotable about a generally vertical axis to extreme positions at either side with respect to the central plane of the rudder. Moreover, there are provided distribution ducts (12A, 12B) which in association with the profile element (20) are adjustable so that the profile element by opposite pivot movement in relation to the angular deflection of the rudder causes seawater to be discharged (12X) along the rudder surface (5B) facing abaft at said angular deflection.
(FR) Un agencement destiné à améliorer l'effet directionnel de gouvernails (5) de bateaux comprend au moins un passage destiné à alimenter en eau de mer, par une pompe, des conduits (11) situés dans le gouvernail, et des dispositifs (20) communiquant avec les conduits et adaptés pour décharger de l'eau de mer fournie par lesdits conduits, à la surface du gouvernail. Lesdits dispositifs comprennent un élément profilé (20) s'étendant de préférence verticalement au niveau du bord avant du gouvernail (5) et pivotant autour d'un axe d'une manière générale vertical, jusque dans des positions extrêmes sur les deux côtés par rapport au plan central du gouvernail. De plus, on a prévu des conduits de distribution (12A, 12B) qui, en association avec l'élément profilé (20), sont réglables de sorte que ledit élément profilé, par un mouvement de pivot opposé par rapport à la déflexion angulaire du gouvernail, provoque la décharge (12X) de l'eau de mer le long de la surface (5B) du gouvernail tournée vers l'arrière dans ladite déflexion angulaire.
