Abstract
The kite employs a flexible leading edge (11) with one or more spines (12, 13) orientated substantially parallel to the longitudinal axis of symmetry of the kite. The spines (12, 13) may be in a number of constructions but substantially all constructions provide a shape so as to assist in producing camber in the kite skin. The kite may include either flexible or rigid bridling with a number of attachment points of the leading edge (11) and spines (12, 13).
Claims
1 . An improved hybrid kite including: a kite skin having a leading edge and a trailing edge, the leading edge of the kite skin being stiffened to improve air flow over the leading edge; one or more flexible spines attached to the kite skin substantially over the entire chord of the kite; and a plurality of bridle attachment points on the kite skin, wherein span-wise rigidity of the kite is provided substantially by components of pressure differential across the kite skin acting in substantially span-wise directions, in conjunction with interaction with bridling attached to the stiffened leading edge and at least two of the spiπe(s).
2. An improved hybrid kite including: a kite skin having a leading edge and a trailing edge, the leading edge of the kite skin being stiffened to improve air flow over the leading edge; one or more flexible spines attached to the kite skin substantially over the entire chord of the kite; and a plurality of bridle attachment points on the kite skin, wherein the stiffened leading edge and/or the spine(s) are adapted to be sufficiently flexible that the entire assembled kite can be packed in a coiled form.
3. An improved hybrid kite as claimed in claim 1 or claim 2 wherein the leading edge is stiffened by a flexible leading edge member which is of small diameter in proportion to the maximum chord of the kite such that it does not contribute significantly to the span-wise rigidity of the kite.
19
4. An improved kite as claimed in claim 1 wherein the spines comprise primary spines traversing the centre of the skin from the leading edge to the trailing edge, and secondary spines running from a point on the skin behind the leading edge to the trailing edge.
5. An improved kite as claimed in any preceding claim wherein the spines are oriented substantially parallel with the longitudinal axis of symmetry of the kite.
6. An improved kite as claimed in claim 1 wherein the bridling includes a plurality of connection points along the leading edge and a plurality of connection points along the length of the spines.
7. An improved kite as claimed in claim 6 wherein the connection points along the spines include a connection point at the junction of the spine and the leading edge (for primary spines), or at a point on the spine (for secondary spines) and the junction of the spine and the trailing edge, along with one or more connection points between the forward end of the spine and trailing edge junction.
8. An improved kite as claimed in any preceding claim wherein the bridling arrangement is in a form adapted for control of the kite by means of two or more lines.
20
9. An improved kite as claimed in claim 1 wherein the kite skin is shaped so that camber is provided.
10. An improved kite as claimed in claim 1 wherein the skin includes foam sections located behind the leading edge.
1 1. An improved kite as claimed in claim 1 wherein the kite skin is constructed from foam, preferably the foam being laminated to or between one or more fabric layers.
12. An improved kite as claimed in claim 1 wherein the skin has panels constructed incorporating foam and/or panels constructed from a fabric.
13. An improved kite as claimed in claims 10, 1 1 or 12 wherein the foam is expanded polyethylene foam or similar material which exhibits the required degree of floatation.
14. An improved kite as claimed in any previous claim wherein camber is provided by incorporating insert panels that increase the area of skin in a region immediately behind the leading edge.
15. An improved kite as claimed in any previous claim wherein the kite skin incorporates, when viewed in plan, a curved leading edge and a substantially straight trailing edge.
21
16. An improved kite as claimed in claim 1 5 wherein the trailing edge is scalloped.
17, An improved kite as claimed in any previous claim wherein the spines are shaped to assist in providing camber in the kite skin.
18. An improved kite as claimed in claim 1 wherein the flexible leading edge member comprises two or more flexible sub-members in a bundle and located at the leading edge, preferably in a sleeve, of the kite.
19. An improved kite as claimed in claim 1 wherein the leading edge member is collapsible, the collapsible functionality effected by means of one or more hinges located at the junction of the leading edge and the spines.
20. An Improved kite as claimed in claim 19 wherein the hinges are in the form of a hinge and pin type arrangement.
21 . An improved kite as claimed in claim 1 wherein the spines include built-in reflex.
22. An improved kite as claimed in claim 21 wherein the reflex is produced by constructing the spine from a combination of materials.
23. An improved kite as claimed in either claim 21 or 22 wherein the spines are constructed in a composite form.
22
24. An improved kite as claimed in claim 23 wherein the spine is constructed with a metal forward section and a fiberglass rear section.
25. An improved kite as claimed in claim 23 wherein the rear section is a carbon fiber or similar material.
26. An improved kite as claimed any preceding claim wherein the rear section of the spines incorporate built-in reflex.
27. An improved kite as claimed in any previous claims wherein the spines are joined to the kite skin by means of a fabric rib or web lattice or open weave fabric, or foam or part foam section.
28. An improved kite as claimed in claim 27 wherein the fabric rib extends below the kite skin whereby the fabric rib is adapted to receive the spine so that when a pressure differential exists between the upper and lower surface of the kite skin, spanwise movement of air substantially immediately under the kite skin is reduced or substantially prevented.
29. An improved kite as claimed in any previous claim wherein the spines are constructed in two parts, an upper and a lower part, wherein the upper part has the shape of an airfoil and the lower part has either a generally linear shape or is curved.
23
30. An improved kite as claimed in claim 29 wherein the upper and lower parts are of different length with the upper part extending from a point proximate the leading edge of the spine to a point between the leading and trailing edge of the resulting spine whereby the upper part is shorter than the lower part and is joined to the lower part so that an airfoil shape is produced between the upper and front portion of the lower part.
31 . An improved kite as claimed in any previous claim wherein some or all of the bridles are in the form of rigid bridles.
32. An improved kite as herein described with reference to the accompanying drawings.
