MOVING VERTICAL AXIS TURBINE FOIL
A new movable foil for accelerating the fluid hitting the blades of a vertical axis turbine is presented.
1 . A vertical axis turbine, comprising:
a. a movable FDD, peripheral to the blades, functionally contiguous to the blades of said turbine, and whose length is in the same axis as the turbine,
b. a means for moving said movable FDD.
2 . The turbine of claim 1 , wherein the turbine is in a liquid.
3 . The turbine of claim 1 , wherein the turbine is in a gas.
4 . The turbine of claim 1 , wherein the movable FDD is a partial foil shape.
5 . The turbine of claim 1 , wherein the means comprises at least one track.
6 . The turbine of claim 5 , wherein the track is supported on at least one separate FDD.
7 . The turbine of claim 1 , wherein the means comprises a tail vane connected to the movable FDD.
8 . The turbine of claim 1 , wherein the means comprises a sensing-controller-motor system for adjusting the position of the movable FDD.
9 . The turbine of claim 1 , wherein the movable FDD does not block the fluid entering the turbine.
10 . The turbine of claim 1 , wherein the FDD partially blocks the fluid entering the turbine.
11 . The turbine of claim 9 , further comprising:
c. a second movable FDD, whether or not attached to the first movable FDD, partially blocking the fluid entering the turbine.
12 . A method of placing a movable FDD functionally adjacent to a vertical axis turbine.
13 . The method of claim 12 , wherein the movable FDD is substantially located at a right angle to the direction of flow.
14 . A non-movable FDD, comprising an attachment for supporting a track.
