Abstract
Official abstract text for this publication.
There is disclosed a fluidfoil comprising a selectively fluid chargeable capillary and a flexible body adjacent the capillary, the shape of the flexible body being adjustable in use via controlling the degree to which the capillary is charged and therefore the forces that the capillary exerts on the flexible body.
First claim
Opening claim text (preview).
1 . A fluidfoil comprising a selectively fluid chargeable capillary and a flexible body adjacent the capillary, the shape of the flexible body being adjustable in use via controlling the degree to which the capillary is charged and therefore the forces that the capillary exerts on the flexible body. 2 . A fluidfoil according to claim 1 where the flexible body is elastic. 3 . A fluidfoil according to claim 1 where the flexible body comprises a suction side wall of the fluidfoil. 4 . A fluidfoil according to claim 3 where the flexible body comprises a pressure side wall of the fluidfoil. 5 . A fluidfoil according to claim 4 where the flexible body comprises a core of the fluidfoil sandwiched between the suction and pressure side walls. 6 . A fluidfoil according to claim 5 where the capillary is contained within the core. 7 . A fluidfoil a cording to claim 1 where there are a plurality of the capillaries. 8 . A fluidfoil according to claim 7 where some or all of the capillaries are arranged in an array of substantially parallel capillaries. 9 . A fluidfoil according to claim 8 where the capillaries of the ray extend in a substantially chordwise direction. 10 . A fluidfoil according to claim 5 where the pressure side wall has a higher stiffness than the suction side wall. 11 . A fluidfoil according to claim 10 where the capillaries of the array are provided adjacent the suction side wall. 12 . A fluidfoil according claim 1 where the flow of fluid to and/or from at least one of the capillaries is valve controlled. 13 . A fluidfoil according to claim 1 that is an aerofoil. 14 . A variable fluidfoil system comprising a pump and a fluidfoil in accordance with claim 1 , where the pump is arranged to selectively deliver fluid to charge the capillary. 15 . A variable fluidfoil system according to claim 14 where the system further comprises a reservoir for storing fluid to be pumped by the pump.
