A device (100) for reducing the drive power requirement of a ship and even for not very quick ships of all types, in particular for slow, full-built ships such as tankers, bulkers and tugboats, and for improving the propeller blower stream as well as for producing a pretwist consists in a front nozzle (20) fixedly installed on the hull (100) with fins or hydrofoils (30a, 30b, 30c, 30d) placed in the inner space (20a) thereof.

Il s'agit d'un dispositif (100) qui permet de réduire les exigences de puissance d'entraînement d'un navire et même pour toutes sortes de bâtiments pas très rapides, en particulier pour des bâtiments lents complètement armés, comme les pétroliers, les vraquiers et les remorqueurs. Ce dispositif permet d'améliorer l'écoulement créé par les pales des hélices, ainsi que pour produire une prétorsion. Il consiste en une buse avant (20) installée à demeure sur la coque (100) avec des ailettes ou des ailes immergées (30a, 30b, 30c, 30d) placées dans l'espace intérieur.
