Definitions

  • the present invention relates to a propulsion and steering arrangement for a vessel.
  • the arrangement is of a kind that comprises a propeller, a rudder arranged behind the propeller, and a bulb-shaped body provided on the rudder.
  • the most common means for propelling a vessel is a screw propeller which has two or more propeller blades.
  • the propulsive efficiency of the propeller which is defined as being the ratio between propulsion (also called effective) power and delivered power, should be as high as possible.
  • GB 762,445 teaches to arrange a bulb-shaped body behind the propeller in extension of the propeller axis.
  • a bulb-shaped body In order to overcome a contraction of the propeller slip stream, it is suggested to push a freely protruding head of the bulb-shaped body closely up to the trailing edge of the propeller blades so as to overlap the propeller hub.
  • a front part of the bulb-shaped body is supported by a rudder post of an unbalanced rudder, while a tail part, or aft part, of the bulb-shaped body is carried by a rudder blade, both parts of the bulb-shaped body being in articulated engagement.
  • the bulb-shaped body is supported by a balanced rudder and the propeller hub has a recess engaged by the protruding head of the bulb-shaped body to allow a swinging movement of the bulb-shaped body relative to the propeller hub when the rudder is turned.
  • EP 0 852 551 A discloses a propulsion and steering arrangement of a vessel, wherein a transition ring screwed on a hub of a screw propeller forms a continuous streamlined body with a bulb-shaped body supported by a rudder horn of a semi spade rudder behind the propeller.
  • the streamlined body is broken only by a narrow rotation gap between the transition ring and the bulb-shaped body.
  • WO 2006/112787 A discloses a propulsion and steering arrangement of a vessel, wherein a fairing hubcap which is integral with a hub of a screw propeller forms a continuous streamlined body with a bulb-shaped body supported by a full spade rudder behind the propeller.
  • the front end of the bulb-shaped body and the hubcap are designed to keep a narrow gap between the bulb-shaped body and the hubcap constant when the rudder is turned.
  • the rudder has a highly sophisticated design based on simulation and optimisation of the form of twisted leading edge that meets the swirling water propelled backwards by the propeller when the propeller drives the vessel in fore direction.
  • the twist angle of the rudder is greatest in the area of the bulb-shaped body and decreases with the distance from the bulb-shaped body.
  • the twisted leading edge profile of the rudder improves the propeller slip stream through the rudder area, thereby increasing propeller efficiency.
  • a propulsion and steering arrangement for a vessel comprising a screw propeller and a turnable rudder arranged behind the propeller.
  • a fairing at a tail end of the propeller and a bulb-shaped body provided on the rudder form a streamlined body which is continuous except for a narrow gap between the fairing and the bulb-shaped body.
  • the rudder has a twisted upper leading edge extending from an upper end of the rudder to the bulb-shaped body and a twisted lower leading edge extending from a lower end of the rudder to the bulb-shaped body.
  • the rudder is characterized in that at least one of the upper leading edge and the lower leading edge has a constant twist angle resulting much more rugged and easy to manufacture rudder than sophisticated solution described in WO 2006/112787 .
  • the propulsion and steering arrangement according to the present invention can achieve the same fuel savings as the conventional propulsion and steering arrangement of WO 2006/112787 A in which the twist of the rudder decreases from the area of the bulb-shaped body towards the upper or lower end of the rudder.
  • the theoretical propulsion efficiency tends to be higher for the propulsion and steering arrangement of WO 2006/112787 A when the rudder is parallel to the axis of rotation of the propeller, propulsion efficiency tends to be higher for the propulsion and steering arrangement according to the present invention when the rudder is turned to steer the vessel.
  • the propulsion and steering arrangement according to the present invention has an additional benefit as the manufacturing costs for the rudder having the constant twist angle are less than those for the rudder of WO 2006/112787 A .
  • both the upper leading edge and the lower leading edge have a constant twist angle.
  • the at least one twist angle is preferably less than 15°, more preferably less than 10°, and most preferably between 5° and 10°.
  • the at least one twist angle decreases in aft direction to 0° within a range defined by the respective leading edge and the pivot axis of the rudder.
  • the bulb-shaped body is preferably provided on a rudder blade of the rudder to allow a swinging movement of the bulb-shaped body relative to the fairing when the rudder is turned.
  • the rudder may be either a full spade rudder or a semi spade rudder.
  • the propulsion efficiency and fuel savings of the propulsion and steering arrangement according to the present invention are the more remarkable the farer the pivot axis of the rudder is disposed from the leading edge of the rudder, or the more the upper and lower leading edges of the rudder are displaced from the axis of rotation of the propeller for a given turning angle of the rudder.
  • the pivot axis of the rudder is preferably located at 30 to 50% of the maximum rudder length from the upper or lower leading edge in aft direction, more preferably at 35 to 50% of the maximum rudder length, and most preferably at 40 to 50% of the maximum rudder length.
