Technical Field
The present disclosure relates to a plurality of vortex generators (vortex generators) interconnected with each other.
Background
Vortex generators typically include some type of protrusion that extends from a surface of a body and is configured to disrupt a boundary layer of a fluid (e.g., air, water, etc.) flowing over the surface. Thus, in some cases, the vortex generators may affect drag properties (drag properties) when the body is moved.
The subject matter is described with specificity and detail throughout this disclosure to meet statutory requirements. The aspects described throughout this disclosure are intended to be illustrative rather than restrictive, and the description itself is not necessarily intended to limit the scope of the claims. Rather, the claimed subject matter may be practiced in other ways to include different elements or combinations of elements equivalent to the ones described in this disclosure. In other words, the intended scope of the claims and other subject matter described in this specification includes equivalent features, aspects, materials, construction methods, and other aspects that are not expressly described or depicted in this application for the sake of brevity, but would nevertheless be understood by those of ordinary skill in the relevant art to be encompassed within this scope in light of the overall disclosure provided herein. It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is covered by and within the scope of the claims.
The present disclosure describes an article including a vortex-generator device attached to a surface. The vortex-generator device typically comprises at least one elongated member interconnecting two or more vortex generators. The vortex-generator device may be attached to a variety of different articles, such as apparel, clothing accessories (e.g., footwear, gloves, headwear, etc.), adhesive bands, athletic equipment, and the like, in order to affect the drag properties of the article. Among other things, the features of the vortex-generator apparatus can provide stability for each of the individual vortex-generators, and can provide a mechanism by which two or more vortex-generators can be treated in common, rather than individually, such as when the vortex-generator apparatus is attached to an article. In other cases, the vortex-generator device may affect a property of the underlying article, such as by reducing the relative stretching of a portion of the article.
One aspect of the present disclosure includes an article of apparel having: the vortex generator includes a layer of material, an elongate member coupled to a surface of the layer of material, and first and second vortex generators coupled to the elongate member. The elongate member has an elongate member length and an elongate member width. The elongate member length extends from the first vortex generator to the second vortex generator, and the elongate member width is less than the elongate member length. Further, each of the first and second vortex generators includes a leading edge and a trailing edge opposite the leading edge. The leading edge and the trailing edge define a vortex-generator length therebetween, and the elongate member width and the vortex-generator length comprise a ratio in a range of about 1.5:1 to about 0.25:1.
Another aspect of the present disclosure includes an article having a vortex-generator device. The article includes a layer of material having a surface. A plurality of elongate members are coupled to the surface, and the elongate members are interconnected with one another. Further, each elongate member of the plurality of elongate members comprises an elongate member length and an elongate member width, the elongate member width being less than the elongate member length. Further, at least two elongated members included in the plurality of elongated members intersect at an apex to form an angle. The article also includes a plurality of vortex generators coupled to the plurality of elongate members and projecting away from the surface. Each elongate member length extends between a respective pair of vortex generators, and at least one of the vortex generators is coupled at a vertex.
Another aspect of the present disclosure relates to a method of constructing a vortex generator apparatus. The method includes filling a vortex-generator device mold with an elastomeric composition in a first state. The vortex-generator device mold includes a plurality of vortex-generator shaped depressions having a first depth and one or more grooves connecting the vortex-generator shaped depressions to one another. The one or more grooves have a second depth that is less than the first depth. The elastomeric composition is cured to a second state when the elastomeric composition is in the vortex-generator device mold, such that the elastomeric composition forms a vortex-generator device when cured. The method also includes applying a bonding agent to a surface of the vortex-generator device, the surface being positioned near a mouth (mouth) of the one or more grooves. The bonding agent is cured while the vortex-generator device is in the vortex-generator device mold. The vortex-generator device is transferred to a fixture having a cavity shape complementary to the vortex-generator device, leaving the surface with the bonding agent exposed. The layer of material is placed against the surface having the bonding agent, and the bonding agent is activated to couple the vortex-generator device to the layer of material.
Having described various aspects of the present disclosure, these and other aspects will now be further described with reference to the drawings. FIG. 1A depicts one type of
As depicted in the enlarged view, the vortex-generator device 12 includes an
In general, the elongate member (e.g., elongate member 14) includes a body that extends in three dimensions (e.g., x, y, and z axes) such that the body has an elongate member length, an elongate member width, and an elongate member thickness, the elongate member length being greater than the elongate member width and the elongate member thickness. Examples of

Thus, the relative sizes of the elongate member and the vortex generator may vary. According to one aspect of the present disclosure, the elongate member width and the vortex-generator length comprise a ratio in a range of about 1.5:1 to about 0.25:1. For example, if the elongate member width is about 5mm, the vortex-generator length may be in the range of about 6.25mm to about 7.5mm, which would provide a ratio in the range of about 0.8:1 to about 0.66:1 — and the vortex-generator length may be smaller or larger, and still fall within the ratio. In further examples, if the vortex-generator length is about 7.5mm, the width of the elongate member may be in the range of about 1.125cm to about 1.875 mm. These are merely examples of some aspects of the present disclosure, and in other aspects, the size ratio within the vortex-generator device may fall outside of this ratio.
As mentioned above, the vortex generators include a vortex-generator height that defines how far the vortex generators protrude from the surface of the article. The burred vortex generator includes a maximum height at the trailing edge, and any alternative vortex generator configuration or shape would similarly include a vortex generator height, which may be at the trailing edge or at any other portion of the vortex generator. In one aspect of the invention, the vortex-generator height is in the range of about 2mm to about 6 mm.
The vortex generator means includes other features. For example, in fig. 1A and 2A-2C, the elongate members form a grid structure or lattice structure, where each elongate member intersects another elongate member at a vertex to form an angle. Furthermore, the lattice structures of fig. 1A and 2A-2C arrange the vortex generators in a matrix, with each vortex generator positioned near a respective vertex. The vortex-generator device may also include other configurations. For example, fig. 3 depicts an exemplary vortex-

Step 722 includes applying a layer of material (e.g., a layer of material of an article of apparel or a layer of material of an adhesive tape) to the surface having the bonding agent while the vortex-generator device is in the jig. If a transfer sheet is applied, the transfer sheet is removed prior to application of the textile layer. At
