Abstract
The utility model discloses a high lift rudder equipped with rotors, which relates to the high lift rudder technical field of the ship engineering and solves the technical problem of improving the steering effect of the high lift rudder. The high lift rudder comprises a main rudder blade and an auxiliary rudder which connects the trailing edge of the main rudder blade. The utility model is characterized in that it also comprises rotors arranged in the groove of the exterior edge of the main rudder blade and a driver arranged on the top end of the rotors, wherein a blade capable of extension is arranged inside the rotors, when the rotors are in rotary with a high speed, the extensional blade can drive more water current move around the main rudder blade and enlarge the pressure difference between the front face of the rudder and the reverse face of the rudder, thereby the utility model has the advantages of making a good steering effect when in an extremely low navigational speed, greatly improving the maneuvering capability of a ship, and being suitable for various special engineering ships which navigate in a low speed. The utility model is suitable for the high lift rudder whose auxiliary rudder is in a flap shape or in a fish tail shape.
Description
Technical field
The utility model relates to the Marine engineering technology, particularly relates to a kind of high lift rudder technology that is provided with rotor.
Background technology
The requirement of the special boat that the needs maneuvering ability was strong when present ordinary rudder was difficult to satisfy lowsteaming in order to improve the turnability of the demanding extraordinary ship of road-holding property, can only have following two kinds of approach at present:
1) strengthen rudder area: the steerage when improving low speed, as not taking extraordinary measure, can only strengthen rudder area.Sometimes even with rudder area be increased to more than 2 times, the maneuvering ability during in the hope of acquisition low speed, but this will cause following adverse consequences:
A) too strengthen rudder area,, light weight is increased the cost of rudder gear is increased;
B) appendage drag of ship is increased, the speed of a ship or plane reduces, and the main frame energy consumption is strengthened;
C) excessive rudder area will cause course stability to degenerate, and more frequent for the manipulation that is maintained fixed course, rudder, the normal boat of ship is drawn influenced, and the speed of a ship or plane lowers, and energy consumption strengthens.
2) aboard ship head and the tail install side thruster additional to assist the boats and ships revolution; The cost of this side thruster generally is much higher than the price of rudder gear, can cause the boats and ships total cost to be greatly improved.
The utility model content
At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides a kind of simple in structure, and cost is low, operate reliable, in light weight, steerage is good, be fit to the high lift rudder that is provided with rotor of lowsteaming boats and ships.
In order to solve the problems of the technologies described above, a kind of high lift rudder that is provided with rotor provided by the utility model comprises the main rudder leaf, it is characterized in that, also comprises being located at the interior rotor of main rudder leaf leading edge groove and the actuator of described apex rotor.
Further, described main rudder leaf trailing edge is rotatably connected to secondary rudder.
Further, be provided with retractable blades in the described rotor.Overhanging blade can drive more current around the motion of main rudder leaf when rotor high-speed rotates, and the pros and cons difference of pressure of rudder is strengthened, thereby makes rudder blade produce good steerage when extremely low rudder speed.
Further, two limits of described main rudder leaf leading edge groove are provided with the inboard briquetting on inclined-plane that is.Can withdraw when making blade in forwarding groove in the rotor.
Further, described rotor is a hollow cylinder.
Further, described actuator is a motor; Described motor is provided with cable and connects controller from main rudder leaf rudder stock bottom in rudder stock.
Further, described actuator is a HM Hydraulic Motor; HM Hydraulic Motor is provided with oil pipe and connects controller from main rudder leaf rudder stock bottom in rudder stock.
Further, described actuator is provided with shell.
Further, described secondary rudder is the secondary rudder of wing flap type.
Further, described secondary rudder is the secondary rudder of fish tail type.
The high lift rudder that is provided with rotor that utilizes the utility model to provide, owing to adopt the rotor structure of band blade in main rudder leaf leading edge, overhanging blade can drive more current and moves around the main rudder leaf when rotor high-speed rotates, the pros and cons difference of pressure of rudder is strengthened, thereby when extremely low rudder speed, make rudder blade produce good steerage; Can produce the much bigger resultant lift of ordinary rudder of having only secondary rudder; Adopt the high lift rudder that is provided with rotor of the present utility model, though cost more than general ordinary rudder, compare strengthen rudder area or aboard ship head and the tail install alternate manners such as side thruster additional, it is cheap that its cost still belongs to, and can avoid above-mentioned many drawbacks.Spacious water-based can studies show that the utility model is provided with the high lift rudder of rotor, in 0-45 degree rudder angle scope, can increase lift 2-3 doubly.Even under the very low speed of a ship or plane, as long as the ship after screw is in operative condition, good steerage is arranged all, other rudder can not be equal to it, thereby needs the strong all kinds of special engineered boats and ships of maneuvering ability when being applicable to lowsteaming very much.
