Abstract
The invention relates to a mast for sailing vehicles, said mast being divided in a lateral direction into two mirror symmetrical mast profiles (mast halves) (1) which merge at or under the top of the mast, which are placed apart on the base of the mast, and which curve outward forming arcs or run in a straight manner. Acting forces are transferred via an inner stay (2) and inner spokes (3), by means of the arrangement and number of which the dimensional stability of the construction and of the static advantage thereof is achieved. A direct flow onto the mainsail (10) is enabled by the division of the mast into two profiles, the design of the mast halves and the profile shape thereof (8), (9) being preferably carried out in an aerodynamic manner.
Description
Technical field
The present invention relates to a kind of mast that is used for various types of sampans, sailing boat and sail formula transportation means; This mast comprise two that separate along side direction each other, transverse to the outside arching of longitudinal axis, arc or mast half one of straight extension; These two mast half ones perhaps flock together below mast tops at the mast tops place; And mast based place or the direct structure width that above mast based, reaches maximum at this mast; The mast leech rope at guy that extends placed in the middle or sail between mast half one of said mast produce vertical tension force and laterally the spoke between mast half one carry transverse force, through the layout of this mast and the shape stability and the statics advantage thereof of this structure of quantity realization.The embodiment of mast section bar preferably and knownly has the advantageous forms that flows.
Background technology
The moment of deflection to mast that wind pressure through side direction in common mast structure form produces imports in the hull of corresponding windward side via shroud in the power that in the shroud tightening device of expansion, is absorbed and produces through (a plurality of) mast crossyard.
Not only mast crossyard but also mast are owing to the predetermincd tension of wind-force and shroud and guy is born pressure.From flow imaging and weight reason, it is elongated as far as possible that mast and mast crossyard keep.But for fear of bending; Its technological elongated property is restricted, so mast has wide section bar and big weight about the resistance of opposing bending in common version and influence becoming a mandarin of when ship sails close to the wind wind unfriendly because its former leechrope remains on the location before the sail in the mast track.When windstream got in the sail, division and at the eddy current in the mast back region of windward side and leeward side took place to flow.
The problem of flow imaging is known and has attempted solving in a different manner.In WO88/03889, this to solving, wherein, must stand the shortcoming of additional ballast through arranging special additional section bar that is provided with on the mast side or water conservancy diversion fin in this solution, and this additional ballast increases heeling moment.
In patent FR 1524392A, US 3724412A, GB 1399421A and FR 2751609A1, do not consider the statics advantage and therefore must stand the higher weight or the less bending resistance of structure.
Summary of the invention
Therefore, the objective of the invention is to, improve statics and also consider positive flow behavior through the version of the mast of type as stated.
In according to mast structure form of the present invention, the power that produces by wind pressure with by predetermincd tension via mast half one that is configured to arcuate shape or straight structure with the form of pressure with via the form transmission of a plurality of spokes and guy placed in the middle with pulling force.
By power situation based on structure of the present invention, with the quantity of employed spoke and said two mast half that realize the thus frequency of separating produce the obvious bigger elongated property of said two section bar half ones of ready property that obviously reduces that mast half one tends to bend and consequent, mast pro rata.
Mast transverse to the resistance torque of wind direction in according to version of the present invention width through version can be obviously more the highland accept.
In addition, according to the statics advantage of version of the present invention through bear drag load and thereby property elongated with it can bear pro rata obviously more that the spoke of top load obtains.And through since the layout frequency of spoke or pressure element provide, better power distributes on the whole length of mast half one.Because according to version of the present invention, obtained mast with the proportional higher stability of its weight.
In a kind of modification according to version of the present invention; Mast half cage structure straighe or part straight; The tendency that on the direction of confirming, bends is in this case through about section bar non-symmetrical (in-to-in) material stress, the protrusion side towards (unlimited, semicircle) section bar of mast half one realizes respectively; And through the corresponding layout of spoke or pressure element, with its frequency pro rata, can avoid bending.
Through between each mast half one, medially arranging sail, can realize directly becoming a mandarin to sail.
Different with utility model G 9207461.8, the fork-shaped scheme of the mast of this design is not to be used for passing the purpose that mast increases big sail surface by boom (Baum), but is used to increase the stability of mast itself.This structure allows on statics, to change extremely effectively high wind pressure trend.
As in patent FR 1 524 392A, US 3 724 412A, GB 1399421A and FR2751609A1, describing ground with similar type, the advantage on the flow imaging is by obtaining to directly becoming a mandarin of sail.In addition, the bigger elongated property of said two section bar half ones of mast provides according to the fin section bar, to flowing and has advantageously constructed the possibility of these section bar half ones, therefore when sailing close to the wind, realizes better becoming a mandarin to mainsail.If structure is configured to rotatable, then can further improve becoming a mandarin.
Be positioned at the in-to-in spoke owing to its little, circular perhaps flattened oval shape cross-sectional plane causes not having tangible eddy current or air resistance value.
Sail can be locked in placed in the middle propping up and draw back or in lighter version (little sampan), on the length of mast leech rope, hook in the spoke or also extension between mast tops and mast based freely (not having a version of locking placed in the middle).
Realize perhaps also additionally propping up to lock realizing via fixing mast based above deck in the hull of Cross Wind Force importing ship or directly via side; These sides prop up lock itself can be in the height of sail center of gravity the lowland, position act on in-to-in and prop up and lock, whole thus equipment weight further alleviates and the center of gravity of mast and equipment is not to reduce not obviously.
In addition, the guiding of convenient first lug sail (Genuasegel) that facing the wind of narrower version of narrower version through the mast that launches and lower shroud.
The specific embodiment
Front elevation according to the ship among Fig. 1; The comprising two masts, half one 1, be positioned at in-to-in guy 2 of mast according to version of the present invention, this guy and arc end 4 be connected with the mode of force closure with mast based 5 and make crooked mast half one vertically along the longitudinal axis tensioning.Spoke 3 is responsible for the mutual tensioning of mast half, transverse to favour longitudinal axis.Optional shroud 6 additionally imports the power that produces in the hull 7.Fig. 2 and Fig. 3 represent the profile shapes 8 of mast half one and 9 the drawing in side sectional elevation that is orthogonal to the mast longitudinal axis.
