Abstract

A vortex ring generator (11) adapted to be associated with a body (12) subjected to fluid flow, the vortex ring generator (11) being adapted to produce a fluid flow in the form of a vortex ring with the fluid flow moving over the body from the vortex ring generator (11).

Claims (19)

1. A vortex ring generator adapted to be associated with a body subjected to fluid flow, the vortex ring generator being adapted to produce a fluid flow in the form of a vortex ring with the fluid flow within the vortex ring moving over the body from the vortex ring generator.
2. A vortex ring generator as claimed at claim 1 wherein the vortex ring generator is designed in accordance with the Golden Section or Phi geometry.
3. A vortex ring generator as claimed at claim 1 or claim 2 wherein the vortex ring generator is centripetal in its action.
4. A vortex ring generator as claimed at any one of the preceding claims wherein the vortex ring generator being associated with the body and comprising at least one or more vanes having an active surface.
5. A vortex ring generator as claimed at claim 6 wherein the vortex ring generator extends forwardly from the body.
6. A vortex ring generator as claimed at claim 6 or claim 7 wherein the vanes are in the form of a whorl.
7. A vortex ring generator as claimed at any one of claims 6 to 8 wherein the active surfaces of the vanes are designed to conform to the Golden Section.
8. A vortex ring generator as claimed at any one of claims 1 to 5 wherein the vortex ring generator comprises at one or more vanes associated with the surface of the body, the path of the vanes spiralling around the body and along the body.
9. A vortex ring generator as claimed at claim 10 wherein the path of the vanes are designed to conform to the Golden Ratio.
10. A vortex ring generator as claimed at any one of claims 1 to 5 wherein the vortex ring generator comprises at least one or more grooves associated with the surface of the body, the path of the grooves spiralling around the body and along the body.
11. A vortex ring generator as claimed at claim 12 wherein the path of the grooves are designed to conform to the Golden Ratio.
12. A vortex ring generator comprising an element adapted to be associated with a body to influence the fluid flow passing over the body, the element comprising an active surface which is adapted to influence the fluid flow, the active surface having a configuration conforming to at least one logarithmic curve of the Golden Section.
13. A vortex ring generator as claimed at claim 13 wherein the curvature of the active surface conforms to the golden section.
14. A vortex ring generator as claimed at any one of claims 1 to 13 wherein a vortex ring is generated by the movement of a fluid past a stationary vortex ring generator.
15. A vortex ring generator as claimed at any cane of claims 1 to 13 wherein a vortex ring is generated by the movement of the body and the vortex ring generator through a fluid.
16. A vortex ring generator as Claimed at any one of claims 1 to 13 wherein a vortex ring is generated by movement of the vortex ring generator.
17. A vortex ring generator wherein a vortex ring is generated and propulsion is created by the powered rotation of the vortex ring generator.
18. A vortex ring generator substantially as herein described.
19. A vortex ring generator substantially as herein described with reference to the accompanying drawings.
