And the steerage of conventional streamline redder is lower relative to the steerage of flap type rudder and rotary-column type rudder, although anticollision problem when opening ice navigation can be avoided, the particular/special requirement of some icebreaker to road-holding property, Ships Turning Ability cannot be adapted to.
Conventional type Fishtail rudder only arranges system stream plate and lower stream plate processed, and mostly is square, unfavorable to afterbody flow field.And gusset stream plate is strengthened at the middle part that do not arrange of conventional Fishtail rudder, the lift of rudder improves limited on the one hand, and the intensity of rudder cannot keep out the collision of ice cube when opening ice navigation on the other hand.The corner of current conventional Fishtail rudder is ± 35 °, makes the turnability of boats and ships and traversing limited ability.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of Fishtail rudder for icebreaker, effectively can improve course stability and the Ships Turning Ability of boats and ships.
The technical scheme that the present invention solves the problem is as follows:
For a Fishtail rudder for icebreaker, comprise the heel, skates and the rudder blade that is positioned at below heel that are arranged on stern, the rectification tail of described rudder blade is fishtail, and the top and bottom of rudder blade are provided with system stream plate and lower stream plate processed, it is characterized in that:
The corner of described Fishtail rudder is ± 70 °.
Further improvement is, is provided with middle reinforced rib in the middle part of described rudder blade, and the distance between the edge of described middle reinforced rib and rudder blade edge is 100-150mm.
Further again, the ratio of the described width of rectification tail and the chord length of rudder is 0.07.
Further, described upper system stream plate is consistent with the shape of lower stream plate processed.
Distance between the edge of described upper and lower system stream plate and the edge of rudder blade is 150-200mm.
Compared with prior art, beneficial effect of the present invention is:
1, the present invention is used for the Fishtail rudder of icebreaker, and maximum rudder angle can reach ± 70 °, thus propeller race is deflected reach more than 90 °, make boats and ships obtain side thrust, substantially increase the turnability of boats and ships and traversing ability.
2, the setting of middle reinforcement gusset has the advantage of two aspects, and one is the lift that can improve rudder, and two is the intensity that can improve rudder blade, keeps out the collision of ice cube when opening ice navigation.
3, by setting suitable ratio between the contra propeller width of Fishtail rudder and the chord length of rudder, while raising lift, can steady pressure center, when equal rudder area, the power of steering wheel effectively can be reduced.
4, by rudder blade width and the upper and lower reasonable set making the spacing flowing plate, while playing the streaming of restriction rudder upper and lower side, improving lift of rudder, afterbody flow field can be improved.
In sum, the present invention effectively can improve course stability and the Ships Turning Ability of boats and ships, improves the ability of the anti-ice block collision of rudder during navigation in ice region simultaneously, improves afterbody flow field, improve the propulsion quality of screw propeller.The present invention is compared with the Fishtail rudder of prior art, and steerage is higher, and intensity is better, adapts to the work of freezing marine site.In addition, during equal rudder area, steering gear power is lower.
Actual steerage of the present invention obtains good checking in on-board testing, as compared to the flap type rudder of similar dimension with close tonnage rescue ship, when rudder angle is constant, the angle of inclination of boats and ships are little, when steady, maximum steering angle is suitable, revolution equal angular required time is few, the extraordinary road-holding property requirement meeting each operating mode, specifically see following contrast (in following form, left side form is flap type rudder, and the right form is Fishtail rudder).
