Abstract:
A tapered rope structure comprises a first rope region, a second rope region, and a splice region. The splice region is between the first and second rope regions and comprises a taper portion, a finish portion, and an overlap portion. The finish portion is arranged between the taper portion and the first rope region. The overlap portion is arranged between the taper portion and the second rope region. A diameter of the first rope region is smaller than a diameter of the second rope region. A diameter of the overlap portion is greater than the diameter of the second rope region. A diameter of the splice region generally decreases from the overlap portion to the first rope region.
Abstract:
A rope and a method of constructing the rope. The rope may be of 12×12 braided construction and include a core for its length. The rope includes a plurality of primary strands, and each of the primary strands includes a plurality of fibers which may be made of a high-friction material. The rope also includes a secondary strand surrounded by the plurality of primary strands. The secondary strand includes a plurality of fibers which may be made of a low-friction material.
Abstract:
Disclosed is a tow warp construction and a process for forming such tow warp construction where such tow warp construction has a longer life span, that is retains its useful dimensions and characteristics longer than known tow warp constructions and consequently has a longer useful life span than known tow warp constructions. Most broadly the construction of the tow warp construction of the present disclosure and process for forming such includes gradually and progressively introducing fibers from a second group of fibers (or “second group of linear elements”) into an otherwise conventional stranding process where fibers from a first group of fibers (or “first group of linear elements”) are being stranded to form strands (or “third group of linear elements”), so as to either or both increase the diameter of the strands and/or substitute the first group of fibers by fibers from the second group of fibers, so as to: a) in the first instance, increase the diameter of the formed strands and subsequently of a strength member formed of the strands, especially for increasing the diameter and strength of the tow warp's strength member in and about the splice braid zone where it connects to a towed object such as a paravane; and b) in the second instance, substitute in a predetermined region on the long dimension of the strands and subsequently in a predetermined region on a long dimension of a strength member formed of the strands fibers of higher creep and/or lower melting points by fibers of lower creep and/or higher melting points, especially for increasing the resistance of the tow warps strength member to bending fatigue.

Abstract:
The invention provides for a tether (44) for tethering an aircraft (10) for airborne wind energy production to a ground station (40), wherein at least a section of said tether (44) comprises a core part (72) of regular geometric shape and at least one spiral part (76, 76', 76") arranged in a helical shape around said core part (72), wherein a surface of said tether (44) comprises at least a part of a surface (72) of said core part and at least a part of a surface of said spiral part (76, 76', 76"). The invention further provides for a system for airborne wind energy production comprising an aircraft (10), a ground station (40) and a tether (44) as mentioned above.
Abstract:
A belt used as a rope which as a strength higher than that of a rope of the same mass and a substantially circular cross section, and which is provided at both sides thereof with belt portions. This belt consists of a narrow woven material (10) composed of warp and weft yarn (6, 7) of synthetic fiber filaments, and has a belt body (2) extending in the lengthwise direction of the belt, a belt portion (4), and a joint portion (3) for connecting the belt body (2) and belt portion (4) together. The belt body (2) is formed by weaving core strings (5) into a hollow weave texture, and the warp yarn density factor of a hollow weave member (22) is set to not more than 0.700. The belt portion (4) has a woven structure in which the warp yarn (6) in the hollow weave member of the belt body (2) and a part or the whole of the core strings (5) in the belt body (2) are interlaced with the weft yarn. The belt portion has a width W not less than 2.0 times as large as that W &cir& _ of the belt body (2). The joint portion (3) is formed so that it transmutes to a woven structure of the belt body (2) or that of the belt portion (4) in a plurality of steps with its weaving width gradually decreasing or increasing.
Abstract:
A cord comprises a braided sheath of strands having an outer surface, an inner surface, and a central hollow portion defined by the inner surface and having a volume and a core within the central hollow portion of the tubular braided sheath, such that when the cord is in a relaxed state the tubular braided sheath has a cylindrical shape and a relaxed volume of the central hollow portion wherein the core does not fill the relaxed volume of the central hollow portion of the tubular braided sheath; when the cord is in a longitudinal tensioned state, the tubular braided sheath elongates under the longitudinal tension such that a tensioned volume of at least a part of the central hollow portion of the tubular braided sheath is less than the relaxed volume; and the inner surface of the tubular braided sheath of tensioned volume contacts and cinches a surface of the core.
