The specific embodiment
Referring now to the accompanying drawing 1-5 that shows preferred implementation of the present invention, the present invention will be described in more detail.
First embodiment
Fig. 1-4 shows according to the propelling of first embodiment of the invention and steering hardware.This propelling and steering hardware are installed in the afterbody of boats and ships.These boats and ships can dispose one or more described propellings and steering hardware.
As shown in Figure 1, comprise screw propeller 2 on the axle drive shaft (not shown) that is installed in boats and ships 40 according to the propelling of first embodiment and steering hardware, and full spade rudder 10, this full spade rudder has rotating rudder blade 11 and mobilizable wing flap 12, described rotating rudder blade 11 is installed at the pivot axis P place on the rudder stock 32 of boats and ships 40 of tail end back of screw propeller 2, and described mobilizable wing flap 12 is hinged to the tail end of the rudder blade 11 of pivot axis P back.In this context, term " back " reference be as shown by arrow F boats and ships 40 direction forward.
Rudder stock 32 is supported by the main bearing 36 of boats and ships 40 afterbodys, and be driven and make rudder blade 11 around pivot axis P aport or starboard rotate, to handle boats and ships 40.Further, driver train 38 be suitable for making wing flap 12 with respect to rudder blade 11 aport or starboard move, to handle boats and ships 40.The mobile rudder blade 11 that is independent of of wing flap 12.
The pivot axis P of the rudder 10 that illustrates is positioned at from last leading edge 14 to about 45% of the long L of maximum rudder of stern direction.The long L of maximum rudder is the ultimate range between last leading edge 14 and following leading edge 15 and the trailing edge 16.Pivot axis P also can be positioned at different positions, but preferred at the 35-50% place of the long L of maximum rudder, to obtain the good balance of rudder 10.Pivot points P is near more from the middle part of rudder 10, and is more little for the steering angle of the needed rudder blade 11 of specific turning efficiency, low ship's speed for example during harbour environment the efficient of rudder high more.
When screw propeller 2 driven shafts drove, screw propeller 2 advanced boats and ships 40 with forward direction F or relative direction backward.When screw propeller 2 advanced boats and ships 40 with forward direction F, the water that has passed screw propeller 2 formed the slip-stream of the swirling water current that flows to rudder blade 11.
Screw propeller 2 has propeller hub 4, and three propeller blades 8 are installed on it.It also can have still less or more blade.But screw propeller 2 is shown as the displacement screw propeller, but also can have fixing spacing.
The tail end of screw propeller 2 is limited by rectification hub cap 6, and described rectification hub cap 6 is installed on the propeller hub 4 with screw thread or shrinkage fit mode (shrink), to form one with propeller hub 4.The recessed profile of the screw propeller wheel hub 4 that illustrates also can be cast into a single part.Rectification hub cap 6 has recess.This recess is engaged by the front end 22 of globoid 20, and described globoid 20 is installed to rudder blade 11 to form one with rudder blade 11 by the flange connection.
The front end 22 of globoid 20 protrudes in the recess of hub cap 6 and does not contact with this recess.It is constant that the front end 22 of the recess of hub cap 6 and globoid 20 bends to gap narrow between the recess of the front end 22 that keeps globoid 20 when rudder blade 11 rotates and hub cap 6.Globoid 20 and hub cap 6 form continuous streamlined body, and this streamlined body is not only interrupted by described narrow gap when rudder blade 11 rotates.In addition, flexibility, contactless hermetically-sealed construction can be set so that the current in the narrow gap minimize between globoid 20 and hub cap 6.The lead screw oar slip-stream when rudder blade 11 does not rotate of recessed hub cap 6 is left from narrow gap and around globoid 20, globoid 20 prevents that propeller race from shrinking in propeller hub 4 back.As a result, reduced the separation losses of propeller hub 4 back.
The cross-sectional plane of globoid 20 is roughly ellipse, and its width is substantially equal to or greater than the diameter at the tail end place of hub cap 6 and have height greater than width.Another effect that this globoid 20 has is the water speed that it has reduced to pass the screw propeller face.Thereby, improved the average wake coefficient and the hull efficiency of boats and ships 40.
The structure of full spade rudder 10 is described now more specifically.Fig. 2 show among Fig. 1 full spade rudder and in 17 places, upper end of rudder 10 cross-sectional plane and at the following cross-sectional plane of the lower end 18 of rudder 10.Fig. 3 and 4 more specifically shows cross-sectional plane and following cross-sectional plane.
Shown in Fig. 2-4, rudder 10 has the fleetline profile, this profile has leading edge 14, following leading edge 15 and trailing edge 16, upward leading edge 14 extends to globoid 20 from the upper end 17 of rudder blade 11, this time leading edge 15 extends to globoid 20 from the lower end 18 of rudder blade 11, and the upper end 17 from wing flap 12 extends to lower end 18 to this trailing edge 16 in globoid 20 back.Last leading edge 14 has 8 ° the first constant twist angle α of direction aport with respect to the line of centers C of rudder 10, and leading edge 15 has 6 ° constant twist angle β with respect to the line of centers C astarboard direction of rudder 10 down.Twist angle α, β can have different values, but preferably less than 15 °, more preferably less than 10 °, best on each direction all between 5 ° to 10 °.
The distortion of the last leading edge that illustrates 14 and following leading edge 15 is reduced to 0 ° to the stern direction in the pivot axis P institute restricted portion by each leading edge 14,15 and rudder 10, make trailing edge 16 non-warping and along straight-line extension.Distortion also can be reduced to 0 ° in by pivot axis P and 16 restricted portions of trailing edge, perhaps distortion can be extended to trailing edge 16 to form a fish tail rudder.
When screw propeller 2 drove boats and ships 40 with forward direction F, the leading edge 14,15 of distortion met with the swirling water current of being pushed to the back by screw propeller 2.The leading edge profile of the distortion of rudder 10 has improved the propeller race that passes the rudder zone, thereby improves propeller efficiency.
The globoid 20 that illustrates has the shape of symmetry.Yet and the leading edge 14,15 of distortion is similar, and globoid 20 can be asymmetric in shape.The angle that forms between the tail end of the rotation axis of screw propeller 2 and globoid 20 can so that: the tail end of globoid 20 is positioned in rudder blade 11 1 sides on the height of rotation axis of screw propeller 2 and is positioned at rudder blade 11 opposite sides under the height of rotation axis of screw propeller 2.Asymmetric shape has the effect of further raising propeller efficiency.
Compare with the standard rudder that does not have globoid 20, the resistance (drag) that rudder 10 produces when 10 ° or littler little deflection angle is higher.Yet the lift of generation is also very high, this means and can use littler deflection angle.This orders about to the big deflection angle greater than 10 ° and develops, and yes for this owing to globoid 20.Yet so big deflection angle only is used for low-speed control usually, and for low-speed handing, the resistance lift of rudder is prior problem relatively.Generally speaking, rudder 10 is compared with standard rudder and is demonstrated better 1ift-drag ratio.
Compare with the standard rudder that does not have wing flap 12, the wing flap 12 of rudder 10 has the function that redirects propeller race.Thereby 1ift-drag ratio further increases, little accurately the turning to when helping thus to hang down ship's speed.
The wing flap 12 of rudder 10 not only has advantage when low ship's speed and big deflection angle, also have advantage when high ship's speed and 10 ° or littler little deflection angle.This is because following reason.When front end 22 that rudder blade 11 turns to globoid 20 comes out from the covering of hub cap 6, destroyed by the continuous streamlined body that globoid 20 and hub cap 6 form, make stream friction increase and form undesirable turbulent flow.Yet by driving wing flap 12, boats and ships 40 can be diverted and need not rotate rudder blade 11 or only need the littler steering angle of rudder blade 11.Thus, compare with the standard rudder that does not have wing flap 12, the manipulation situation that the front end 22 of globoid 20 comes out from the covering of hub cap 6 can tail off.Thereby, obtained sizable conservation of fuel amount.
In fact, the efficient of wing flap 12 make can allow longer and make hub cap 6 shorter from the front end 22 of the outstanding globoid 20 of rudder blade 11 front ends.Because hub cap 6 is shorter, the turning unit between screw propeller face and the rudder 10 is littler on length, and it has reduced stream friction and has further raised the efficiency.
This all makes the size that might reduce rudder 10, and it has reduced loss due to friction again and has improved single-piece efficient.
Efficient benefits especially greatly for the screw propeller with relatively large propeller hub, and for example RoRo boats and ships, RoPax ferryboat, freight container/multi-functional boats and ships or the top load that has on the freighter of ice class notation (ice classnotation) are controlled apart from propeller system.Because big ratio between diameter of propeller and the hub diameter, for the combination of traditional screw propeller and rudder, the propeller hub loss will become remarkable.By using propelling and the steering hardware according to first embodiment, these losses are most of can be avoided.
In addition, benefiting for the full depot ship of single-blade (full block ship) can highly significant.Globoid 20 causes wake coefficient to become big, therefore also cause hull efficiency to improve, therefore, for the single-blade ship with full afterbody (full aft bodies) (its may have very difficult tail field and high wake coefficient), for example oil carrier, bulk carrier and small-sized cargo ship, annual saving amount also are worth investment very much.
Second embodiment
Fig. 5 shows propelling and the steering hardware according to second embodiment of the invention on the afterbody that is installed in boats and ships 40.
As shown in Figure 5, comprise the screw propeller 2 on the axle drive shaft 30 that is installed in boats and ships 40 according to the propelling of second embodiment and steering hardware and be installed to half spade rudder 10 ' of the hull of boats and ships 40 in screw propeller 2 back.Half spade rudder 10 ' comprises the fore head 34 of the hull that is fixed to boats and ships 40, be installed at the pivot points P place boats and ships 40 rudder stock 32 rotating rudder blade 11 and be hinged to the movable wing flap 12 of the tail end of rudder blade 12.
The main bearing 36 that rudder stock 32 is set in the bottom of fore head 34 supports, and be driven make rudder blade 11 around pivot axis P aport or starboard rotate, to handle boats and ships 40.Further, be provided with in rudder blade 11 inside the driver train (not shown) be used to make wing flap 12 with respect to rudder blade 11 aport or starboard move, to handle boats and ships 40.The mobile rudder blade 11 that is independent of of wing flap 12.
It is long that the rudder 10 ' that illustrates has a constant rudder in bow tail direction.The pivot axis P of rudder blade 11 is positioned at about 41% and sentences and obtain the good balance of rudder 10 '.
Screw propeller 2 has propeller hub 4, and four propeller blades 8 are installed on it.It also can have still less or more blade.But screw propeller 2 is shown as the displacement screw propeller, but also can have fixing spacing.
Propeller hub 4 is cast into the single parts with fairing shape, and it is recessed a little to its tail end.Replacedly, fairing can be a hub cap, and it is installed on the propeller hub with screw thread or shrinkage fit mode.Propeller hub 4 has recess, and described recess engages and do not contact with described recess with the front end of globoid 20.The front end of the recess of propeller hub 4 and globoid 20 bends to the gap that keeps narrow when rudder blade 11 rotates constant.Globoid 20 and propeller hub 4 forms continuous streamlined body, and it is only interrupted by narrow gap, with allow globoid 20 when rudder blade 11 rotates with respect to propeller hub 4 oscillating motions.Streamlined body prevents the contraction of propeller race, has therefore reduced separation losses.
The cross-sectional plane of globoid 20 is roughly ellipse, and its width is substantially equal to or greater than at the diameter at the tail end place of hub cap 6 and have height greater than width.It is the water speed that it has reduced to pass the screw propeller face that this globoid 20 has another effect.Thereby, the average wake coefficient and the hull efficiency of boats and ships 40 are provided.
Similar with full spade rudder 10 according to first embodiment, have the fleetline profile according to half spade rudder 10 ' of second embodiment, described profile has the following leading edge 15 of last leading edge 14, distortion of distortion and non-warping and with linearly extended trailing edge 16.Last leading edge 14 extends to the lower end of fore head 34 from the upper end of fore head 34.Following leading edge 15 extends to globoid 20 from the lower end 18 of rudder blade 11.Last leading edge 14 has the first constant twist angle with respect to the line of centers astarboard direction of rudder 10 ', and down leading edge 15 has with respect to this line of centers constant twist angle of direction aport.Twist angle has the value less than 15 °, more preferably less than 10 °, most preferably on each direction all between 5 ° to 10 °.The distortion of last leading edge 14 is reduced to 0 ° to the stern direction towards rudder stock 32.The distortion of following leading edge 15 is reduced to 0 ° to the stern direction in the pivot axis P institute restricted portion by following leading edge 15 and rudder 10 '.Scope between pivot axis P and trailing edge 16 also can be twisted.
When screw propeller 2 drove boats and ships 40 with forward direction, the leading edge 14,15 of distortion met with by the swirling water current of screw propeller 2 to pusher.The leading edge profile of the distortion of rudder 10 ' has improved the propeller race that passes the rudder zone, thereby improves propeller efficiency.
Similar with propelling and steering hardware according to first embodiment, the 1ift-drag ratio of rudder 10 ' is better than the standard rudder that does not have globoid 20.1ift-drag ratio when the wing flap 12 of rudder 10 ' has further improved low ship's speed, little accurately the turning to when helping low ship's speed thus.In addition, by driving wing flap 12, boats and ships 40 can be diverted and need not rotate rudder blade 11 or only need the littler steering angle of rudder blade 11.Thus, compare with the standard rudder that does not have wing flap 12, the manipulation situation that the front end 22 of globoid 20 comes out from the covering of propeller hub 4 can tail off.Thereby, obtained sizable conservation of fuel amount.The efficient of wing flap 12 makes and might allow longlyer and make propeller hub 4 shorter from the front end 22 of the outstanding globoid 20 of the front end of rudder blade 11, perhaps reduces the size of rudder 10 ', thereby further raise the efficiency.
Similar with propelling and steering hardware according to first embodiment, for the screw propeller with relatively large propeller hub and for the full depot ship of single-blade (full block ship), the efficient of rudder 10 ' benefits especially big.
