Description
Affiliated technical field
The present invention relates to a kind of marine installation, particularly relate to a kind of rudder gear that is used to handle motion of ship behind the propeller for vessels that is installed on.
Background technology
Motor-driven or manipulation when boats and ships navigate by water in water all is to rely on rudder gear as collision prevention, revolution etc. basically, so rudder is the important device that guarantees safety of ship.The rudder its working principles is that the hydrodynamic force generation deflecting torque of utilizing water to act on the rudder forces ship turning.Desirable rudder gear one is should the steerage height, and promptly the transverse force that produced down of equal conditions is big as far as possible; The 2nd, screw propeller there is positive-effect, promptly help to improve the propulsion coefficient of screw propeller; The 3rd, rudder itself does not form resistance and thrust is provided.In general, rudder is installed on the back of marine propulsion screw propeller, exactly because the water velocity behind the screw propeller helps improving steerage greatly, thereby conversely behind the oar rudder also help rectification to improve propeller propulsive efficiency.Existing multiple extraordinary rudder obtains practical application outside the ordinary rudder at present, as flap, rotor rudder, reaction rudder, rectification cap rudder, active rudder etc.These rudders or in order to improve steerage such as flap, rotor rudder, or in order to improve propulsion coefficient such as rectification cap rudder.Active rudder has the effect of high steerage and boosting, and reaction rudder then has the function that improves propulsion coefficient and boosting concurrently.The relatively new rudder of releasing has Propac rudder, schilling rudder (schilling rudder) etc.Document " several marine energy-saving technology performance analysiss " has been introduced energy-conservation boost installation (China and foreign countries' boats and ships science and technology of some current popular; 21 pages of 2009 the 1st phases).Yet regardless of these rudder design-calculated departure points, its basic ideas all are that (with the propeller axis was about the battery limit (BL) divides about the vertical rudder blade that is placed in behind the screw propeller was designed to, the part that promptly is higher than axis is the upper body, and the part that is lower than axis is a lower body) form of fixing, fusing.Because cause current thereafter also correspondingly to form spiral fashion after the screw propeller rotation, the flow condition in zone is reverse about the propeller axis.Therefore see that from hydromechanical viewpoint just there is a problem in the design of above-mentioned siamesed up and down, promptly when after the steering when if rudder blade the first half is in best dynaflow state, the latter half just is not easy to be in dynaflow state well.Vice versa.Owing to will take into account left and right sides steering, the bench section of rudder is symmetric basically in addition, and its hydrodynamic performance can not show a candle to the camber asymmetric airfoil.Flap, rotor rudder propose for overcoming symmetric problem exactly.In addition current characteristics such as reaction rudder etc. behind the screw propeller have been considered in some rudder design, and the extraordinary rudder of this class is characterised in that the distortion in the opposite direction of staggering respectively of the leading edge of rudder blade top and the bottom and/or trailing edge.But on it lower body still relative fixed fuse, whole rudder rotates together in the same way during steering, thereby still can not take into account the difference of flow condition up and down after steering.Therefore this design helps little to improving steerage, only when balance position when claiming amidship (when not steering keeps the boats and ships direct route or) since rudder blade twist to form best angle of attack mode, help reclaiming screw propeller and make part idle work (being the current rotating energies) and be translated into thrust, also can reach the raising propeller propulsive efficiency simultaneously.In sum, existing rudder be the bench section substantially the symmetry, the exhibition to single integrally rotated rudder blade, may be defined as the monomer rudder.Its advantage is can be by single rudder stock steering, and deficiency is to fail to make full use of flox condition and brings into play maximum hydrodynamic performance and come boosting and improve steerage.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of propeller race characteristics that can make full use of to improve steerage, the rudder gear of while self energy boosting.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: with rudder blade is that the boundary is divided into up and down independently, two parts of difference steering control with the propeller axis, promptly goes up rudder blade and following rudder blade.Profile, the size of last rudder blade and following rudder blade can be inconsistent, and as above rudder blade is less rectangle rudder blade for bigger trapezoidal rudder blade descends rudder blade, or on the rudder blade cross section shape be that to descend rudder blade be asymmetry etc. to symmetric figure.The bench section of last rudder blade and following rudder blade also can be all the asymmetric aerofoil profile that camber is arranged.The balance position of last rudder blade and following rudder blade when claiming amidship (i.e. when not steering keeps the boats and ships direct route or) is arranged X type structure in the formation horizontal surface according to the screw propeller hand of rotation is staggered in face of angle of hand of rotation deflection.Last rudder blade 1 and following rudder blade 2 dispose rudder blade and rudder stock 3 and following rudder blade and rudder stock 4 respectively.Wherein: the last rudder blade and rudder stock 3 of going up rudder blade 1 is a hollow shaft, and the following rudder blade and rudder stock 4 of following rudder blade 2 is a solid axle, and last rudder blade and rudder stock 3 is enclosed within down and forms coaxial mode on the rudder blade and rudder stock 4.Be provided with between the upper surface of the lower surface of last rudder blade 1 and following rudder blade 2 and be convenient to install in relative rotation as antifriction-bearing box etc.Concrete rudder blade shape, parameter choose and the layout of balance position is determined to satisfy such requirement based on fluid mechanics principle according to the objective condition of application: go up rudder blade and following rudder blade during balance position and be in the dynaflow state of maximum and all should have the thrust component that helps boats and ships to move ahead; And their side force component size equal direction is opposite.Reaching under the prerequisite of above-mentioned requirements, manoeuvre of ship by independent rotation go up rudder blade or down rudder blade (decide) according to the ship turning direction thus the dynaflow size and even the direction destruction side force balance that change on it reach.Reached the purpose that obtain maximum steerage because last rudder blade and following rudder blade all are in best dynaflow state this moment.
There are fundamental difference in the present invention and existing rudder: the rudder blade of existing rudder is to finish manipulation by acquisition dynaflow after rotating an angle, and the present invention just obtains maximum fluid power when balance position, finish manipulation by breaking the side force balance.The latter's advantage is can make full use of the propeller race characteristics to improve steerage, and self can boosting simultaneously.Because its state of equilibrium is design point thereby can accurately designs at design phase and guarantee to provide maximum thrust and side force, and owing to last rudder blade, following rudder blade are independent fully except that need are coaxial, also is to design to provide more choices.
