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.
- a vessel having the afore-mentioned propulsion and steering arrangement.
- Figs. 1 to 4 show a propulsion and steering arrangement according to a first embodiment of the present invention.

- the term "behind” refers to the fore direction of the vessel as indicated by arrow F.
- the propeller 2 When the propeller 2 is driven by the drive shaft, the propeller 2 propels the vessel in either the fore direction F or in the opposite aft direction.
- water that has passed the propeller 2 forms a slip stream of swirling water which travels towards the rudder 10.
- the propeller 2 has a hub 4 on which three propeller blades 8 are mounted. It can also have less or more blades.

- the tail end of the propeller 2 is defined by a fairing hubcap 6 which has been screwed on or shrunk on the propeller hub 4 to be integral with the hub 4.
- the illustrated outer contour of the propeller hub 4 can also be cast in a single piece.
- the fairing hubcap 6 has a recess. The recess is engaged by a front end 22 of a bulb-shaped body 20 which has been attached to a rudder blade 10a of the rudder 10 by means of a flange connection to be integral with the rudder blade 10a.
- the front end 22 of the bulb-shaped body 20 projects into the recess of the hubcap 6 without contacting the recess.
- the recess of the hubcap 6 and the front end 22 of bulb-shaped body 20 are curved to keep a narrow gap between the recess of the hubcap 6 and the front end 22 of the bulb-shaped body 20 constant when the rudder 10 is turned.
- the bulb-shaped body 20 and the hubcap 6 form a continuous streamlined body which is broken only by the narrow gap.
- the streamlined body prevents a contraction of the propeller slip stream, thereby increasing propeller efficiency.

- the twists of the illustrated upper and lower leading edges 12, 13 decrease in aft direction to 0° within a range defined by the respective leading edge 12, 13 and the pivot axis P of the rudder 10, so that the trailing edge 15 is not twisted and extends in a straight line.
- the twists can also decrease to 0° within a range defined by the pivot axis P and the trailing edge 15, or the twists can continue up to the trailing edge 15 so that a fishtail rudder is formed.
- the twisted leading edges 12, 13 meet the swirling water propelled backwards by the propeller 2.
- the twisted leading edge profile of the rudder 10 improves the propeller slip stream through the rudder area, thereby increasing propeller efficiency.
- the pivot axis P of the illustrated rudder 10 is located at about 45% of a maximum rudder length L from the upper leading edge 12 in aft direction.
- the pivot axis P can also be located at a different position, but preferably at 35 to 50% of the maximum rudder length L to achieve a good balance of the rudder 10.
- the pivot axis P of the illustrated rudder 10 is located within the above-mentioned range of the maximum rudder length L, the displacement of the leading edges 12, 13 of the rudder 10 from the axis of rotation of the propeller 2 is large for a small turning angle of the rudder 10.

- the manufacturing costs for the rudder 10 having the constant twist angles ⁇ , ⁇ is less than those for the rudder of WO 2006/112787 A which has changing twist angles.
