4 kinds of rudders configuration on more than, on the basis of comparative example 1, the propulsive performance of measure BHP (horsepower) benchmark improves effect
Fruit.Measurement result is listed in Table 1 below.
(table 1)
| The propulsive performance improvement of BHP (horsepower) benchmark | |
| The Fig. 7 (a) of embodiment 1/ | - 5.2% |
| The Fig. 7 (b) of embodiment 2/ | - 3.6% |
| The Fig. 7 (c) of comparative example 1/ | Benchmark |
| The Fig. 7 (d) of comparative example 2/ | - 4.5% |
The relative comparative example 1 for forming benchmark, in embodiment 1, confirm about 5.2% improvement.In addition, equally in reality
Apply in example 2, confirm about 3.6% improvement.In this occasion, configured by the asymmetrical rudder in left and right, thrust deduction coefficient, wake
The propulsive elements of coefficient improve.Confirm in addition, in relative right bladed propeller, 1 rudder is arranged at the occasion of right string S sides, pushability
Can be excellent.
In addition, the relative comparative example 1 for forming benchmark, in comparative example 2 of 2 rudders close to pars intermedia, confirms about 4.5%
Improvement.Like this, the occasion of 2 rudders is symmetrically being set, had by making 2 rudders close to middle, wake effect
The tendency that fruit improves.Then it is believed that even if being in propeller face, in the case that asymmetricly 2 rudders are set, reducing
The occasion at the interval of 2 rudders, still can further improve propulsive performance.
The rudder configuration structure of the ship of embodiments of the present invention is illustrated above, still, the invention is not restricted to
Above-mentioned embodiment, other various changes can be carried out.
For example in the above-described embodiment, size, the shape of multiple rudders are identical, but it is alternatively different sizes, shape
Shape.
In addition, multiple rudders act in linkage, but also can independently act.
Further, being watched from hull rear, the direction of rotation of propeller is to turn right, but can also be turned left.
Further, the quantity of multiple rudders is also greater than equal to 4.
In addition, also other rudder can be additionally set in the outside in propeller face or the front of propeller.
In addition, the configuration left and right that " left and right is asymmetric " in the present invention refers to the rudder on the basis of the rotary shaft of rudder is asymmetric,
It is asymmetric the shape of the rudder of left and right in itself or so is not referred to.If the configuration left and right of the rudder on the basis of the rotary shaft of rudder is asymmetric,
Even if then the rudder of left and right in itself to be shaped as left and right asymmetric and not related.
