Title
(EN) METHOD FOR GENERATING WAVE MOTION FOR PROPULSION OF WATERCRAFT
(FR) PROCÉDÉ DE PRODUCTION DU MOUVEMENT DE VAGUES D'UN NAVIRE
Abstract
(EN)
The invention refers to a method which consists in that a specific number of elements, hereinafter referred to as the arms (2), are put into motion in the plane perpendicular to the fluid flow direction, and project from the hull of the watercraft at a specific part of their length. Each of the arms (2) is propelled with an individually designated motion generator (3) of a variable amplitude (A) and frequency (f) of displacements, controlled by the electronic central control unit (4).
(FR)
L'invention porte sur un procédé utilisant un nombre spécifique d'éléments dits 'bras' (2) se mouvant dans une direction perpendiculaire à l'écoulement d'un fluide, et saillant de la coque d'un navire en un point spécifique de sa longueur. Chacun des bras (2) est mu par son propre générateur (3), pour produire des mouvements d'amplitude (A) et de fréquence (f) variables, commandés par une unité informatique centrale (4).
