Abstract

L'invenzione si riferisce ai timoni per imbarcazioni. Per eliminare il contributo permanente alla resistenza idrodinamica passiva dello scafo prodotto dai timoni durante i lunghi periodi di non operatività su rotte rettilinee, l'invenzione prevede un timone comprendente due pale (3) con opposto profilo alare (103) che sono disposte nella zona di poppa (4) dello scafo, distanziate tra loro trasversalmente allo stesso e simmetricamente rispetto alla mezzeria dell'imbarcazione e che sono spostabili nei due sensi in direzione verticale, alternativamente da una contemporanea posizione sollevata inattiva in una posizione attiva d'immersione, in cui la pala (3) rispettivamente immersa determina la virata o la deviazione di rotta dell'imbarcazione nella corrispondente direzione, e vice versa.The invention relates to rudders for boats. To eliminate the permanent contribution to the passive hydrodynamic resistance of the hull produced by the rudders during long periods of non-operation on straight routes, the invention provides a rudder comprising two blades (3) with opposite wing profile (103) which are arranged in the area of stern (4) of the hull, spaced from each other transversely to the same and symmetrically with respect to the center line of the boat and which can be moved in both directions in the vertical direction, alternately from a simultaneous raised inactive position in an active diving position, in which the paddle (3) respectively immersed determines the boat's turn or course deviation in the corresponding direction, and vice versa.
