HYDRODYNAMIC DUCT FOR THE WATER FLOW MANAGEMENT AT THE SHIP'S PROW

摘要

Novelty: Prow hydrodynamic duct. Constitution: A horizontal vane (1) and two lateral vanes (2, 3) defining a water flow space at he ship's prow, inside the invented duct the characteristics of which water flow inside the duct is different from those featured by water flow outside the duct what leads to the decrease of the friction and wave resistances and, consequently, to the decrease o of the conventionally required fuel consumption needed for the propulsion of the ship. Said duct is placed in such a way that the Minimum Pressure Centre (1c) of the horizontal blade (1) is encountered at the generation region of the first prow wave and the Minimum Pressure Centre (2c,3c) of the lateral vanes (2,3) at the connection region of the lateral vanes (2,3); the horizontal blade (1) is located in a selected position between the Minimum Pressure Centre (1c) and the water flow incidence edge (1a) of the horizontal blade (1) and/or slightly projected from said incidence edge (1a).
