Filed:

Sep 16, 2002

Appl. No.:

10/489642

Inventors:

Lena Marie Davis, legal representative - Bedford, CA
Emmanuel Grillos - Bellevue WA, US
Stephen Allison - North Vancouver, CA

Assignee:

Clean Current Power Systems Inc. - Vancouver, B.C.

International Classification:

F03B 13/00
F03B 13/10
H02P 9/04

US Classification:

290 54, 290 43

Abstract:

An apparatus is disclosed for a turbine for generating electrical power from water or air flow comprising at least one rotor disk having a plurality of hydrofoil blades, a guide vanes, a cylindrical housing, and a generator means. A rim generator comprising a magnet race rotor rim and fixed stator coils in the housing is used. The apparatus is fitted with a screen to stop the ingress of debris and marine life, and a skirt augmenter device to reduce the Betz effect. The apparatus is preferably for sub-sea deployment and driven by tidal currents, but may be powered by river current or wave driven air or by wind. The apparatus may be deployed on at least one telescoping pole, tethered to the sea-bed and kept buoyant by buoyant concrete in the housing, inserted in a dam, under a barge or in a tidal power array.

International Classification:

F03D 1/02

US Classification:

415 45, 415 60, 415148, 415908

Abstract:

A flow enhancement improvement for an underwater turbine generator () is disclosed wherein a longitudinal hole () is disposed in the central area (), typically a hub () of the generator (), and a second, augmentor duct (), preferably rigid, is disposed about the outer duct () or housing of the unit to create a slot () area. The slot () and hollow hub () create areas of smooth, laminar fluid flow. The leading edges of the hub () or central ring and the augmentor () and outer ducts () are elliptical to enhance the fluid dynamics of the structure.

US Classification:

244119, 2441231, 244131, 52364, 527871, 527901

Abstract:

Internally stiffened composite panels and associated manufacturing methods. An internally stiffened composite panel can include a first face sheet, a second face sheet offset from the first face sheet, and at least one core portion sandwiched between the first and second face sheets. The composite panel can further include a stiffener disposed between the first and second face sheets adjacent to the core portion. The stiffener can have a first attachment portion attached to the first face sheet, a second attachment portion attached to the second face sheet, and an intermediate portion extending between the first and second attachment portions. One or both of the first and second attachment portions can be configured to engage a fastener, such as a blind fastener, for attaching a part to the composite panel.

Abstract:

Internally stiffened composite panels and associated manufacturing methods. In one embodiment, an internally stiffened composite panel includes a first face sheet, a second face sheet offset from the first face sheet, and at least one core portion sandwiched between the first and second face sheets. In one aspect of this embodiment, the composite panel further includes a stiffener disposed between the first and second face sheets adjacent to the core portion. The stiffener can have a first attachment portion attached to the first face sheet, a second attachment portion attached to the second face sheet, and an intermediate portion extending between the first and second attachment portions. In another aspect of this embodiment, one or both of the first and second attachment portions is configured to engage a fastener, such as a blind fastener, for attaching a part to the composite panel.
