Abstract

A hand-held wing rig includes an inflatable front tube forming a leading edge and a rigid or inflatable center strut which together span a canopy. A radially projecting spoiler profile is formed approximately in the lower region of the leading edge. In use, the spoiler profile is tangentially flowed against, facing a user. Further disclosed is a kite including a spoiler profile formed approximately in the lower region of the leading edge, which is tangentially flowed against.

Claims (33)

1. A hand-held wing rig comprising:

an inflatable front tube forming a leading edge; and

a rigid or inflatable center strut on which a handle can be arranged; wherein:

the inflatable front tube together with the rigid or inflatable center strut span a canopy; and

a radially projecting spoiler profile is formed on the leading edge of the front tube;

wherein:

either the spoiler profile is formed as an attached profile body; and/or

the spoiler profile is covered by a cover; and/or

the spoiler profile has a widened base provided with an adhesive layer; and/or

a plurality of spoiler profile sections are arranged spaced apart from each other; and/or

a plurality of spoiler profile sections are designed with different heights.

2. The hand-held wing rig according to claim 1 , wherein the spoiler profile is formed on an underside of the leading edge facing a user, and in use is flowed against approximately tangentially, and/or the spoiler profile follows a contour of the leading edge in its longitudinal direction at least section-wise.

3. The hand-held wing rig according to claim 1 , wherein the spoiler profile has a height of more than 5 mm.

4. The hand-held wing rig according to claim 3 , wherein an outer skin of the front tube is made of a textile material or a laminate/foil material or a hybrid material, wherein the height of the spoiler profile is lower when using a textile material than when using a laminate/foil material, wherein the height is ≥5 mm, when a textile material is used and is ≥7 mm when a laminate/foil material is used and, in a case of a hybrid material, corresponds at least to the height assigned to a base material in a seaming area, the base material being a textile, laminate, and/or foil.

5. The hand-held wing rig according to claim 1 , wherein the spoiler profile is formed as a seam.

6. The hand-held wing rig according to claim 1 , wherein the spoiler profile extends substantially between tips of the wing rig.

7. The hand-held wing rig according to claim 1 , wherein the spoiler profile is adapted to generate a laminar or turbulent stall or a flow reversal at the wing rig's underside, and/or wherein the spoiler profile forms a stalling edge.

8. A kite comprising an inflatable front tube forming a leading edge and at least one strut, wherein:

the inflatable front tube and the at least one strut together span a canopy, and

a radially projecting spoiler profile is formed on the leading edge of the front tube, and further wherein:

either the spoiler profile is formed as an attached profile body; and/or

the spoiler profile is covered by a cover; and/or

the spoiler profile has a widened base provided with an adhesive layer; and/or

a plurality of spoiler profile sections are arranged spaced apart from each other; and/or

a plurality of spoiler profile sections are designed with different heights.

9. The kite according to claim 8 , wherein the spoiler profile is formed on an underside of the leading edge facing a user, and in use is flowed against approximately tangentially, and/or the spoiler profile follows a contour of the leading edge in a longitudinal direction thereof at least section-wise.

10. The kite according to claim 8 , wherein the spoiler profile has a height greater than 3 mm.

11. The kite according to claim 10 , wherein an outer skin of the front tube is made of a textile material or a laminate/foil material, wherein the height of the spoiler profile is less in a case of a textile material than in a case of a laminate/foil material, wherein the height is ≥3 mm when using a textile material and is ≥5 mm when using a laminate/foil material and, in the case of a hybrid material, corresponds at least to the height assigned to a base material in a seaming area, the base material being a textile, laminate, and/or foil.

12. The kite according to claim 8 , wherein the spoiler profile is formed as a seam.

13. The kite according to claim 8 , wherein the spoiler profile extends substantially between tips of the kite.

14. The kite according to claim 8 , wherein the spoiler profile is adapted to create a laminar or turbulent stall or a flow reversal at an underside of the kite, and/or wherein the spoiler profile forms a stalling edge.

15. The hand-held wing rig according to claim 3 , wherein the height of the spoiler profile is ≥6 mm when a textile material is used, and ≥8 mm when a laminate/foil material is used.

16. The kite according to claim 11 , wherein the height of the spoiler profile is ≥5 mm when using a textile material and ≥7 mm when using a laminate/foil material.
