Description
TITLE OF THE (INVENTION
STEERABLE FLUID CURRENT POWERED TURBINE
FIELD OF THE (INVENTION
The present invention relates to turbines. More specifically, the present invention is concerned with a steerable turbine powered by fluid currents, such as, for example, winds.
BACKGROUND OF THE INVENTION
Various wind turbines used for converting wind energy to a rotary motion, are known. Conventional wind turbines usually include a rotatable shaft, a base or stand to hold up the shaft and a plurality of blades fixedly mounted to the shaft. Under the force of winds, the blades cause the rotation of the shaft and the rotational movement can be transformed in electricity or other form of energies.
In order to maximize the force of the wind onto the blades, the orientation of the shaft can be varied so as to maximize the effective surface of the blades. Conventionally, the shaft and blades assembly is in .a form similar to a wind vane and thus can be self-aligned automatically iin the direction of the dominating wind.

Conventionally, the shaft and blades assembly is in .a form similar to a wind vane and thus can be self-aligned automatically iin the direction of the dominating wind.
A drawback of such self-aligning wind turbines is that the blades are hit from all sides by the wind and thus are subject to turbulence.
Furthermore, the size of the blades is proportional to the desired amount of energy to produce and are thus often bulky.
OBJECTS OF THE INVENTION
An object of the present invention is therefore to provide an improved fluid turbine.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning now to the appended Figures 1 to 6, a steerable fluid current powered turbine 10 according to a preferred embodiment of the present invention will be described. For illustration purposes only, the steerable fluid current powered turbine 10 is illustrated herein as a vertical axis wind turbine.
It is to be noted that the appended drawings schematically illustrate the turbine 10.
The wind turbine 10 comprises a base 12 housing a generator assembly 14, a vertical rotatable shaft 16, a plurality of blades 18 fixedly mounted to the shaft 16, a cylindrical enclosure 20, a steering assembly 22 (f=figure 4), a current direction detector 23 and a controller 25.
The base 12 is advantageously in the form of a hollow structure and is configured and sized to host the generator assembly 14, part of the steering assembly 20 and the controller 25. The base 12 also allows the overall height of the wind turbine 10 to be increased.
Turning now more specifically to Figure 1, the generator assembly 14 inclludes a cogwheel 24 and four generators 26 each having a gear 28 rotatably mounted to one of the generators 26. The gears 28 are configured and sized so as to cooperate with the teeth of the cogwheel24.
The generator assembly 14 is also connected to or includes other conventional circuitry for producing electricity from the rotational motion of the shaft 16.
The generators 26 are believed to be well known to a person of ordinary skills in the art and thus will not described in more detail herein.
Although, the generator assembly 14 is described having four generators 14, it is believed within the reach of someone skilled in the ai~t to conceive a generator assembly having less or more generators.
The shaft 16 is fixedly mounted to the cogwheel 24 at the center thereof and includes six pairs of blades 18 (only one blade of each pair being shown in Figure 3). The blades 18 are fixedly mounted to the shaft 14 via a hub 30 secured to the shaft 14 and coaxial thereto.
Although the blades 18 are advantageously hemi-spherical in shape, the wind turbine 10 can be provided with blades having other shapes without departing from the spirit of the present invention. Similarly, the number of blades can also be different.
The cylindrical enclosure 20 is coaxially mounted about 5 the shaft 14. The cylindrical enclosure 20 is sized so as to snugly fit around the blades 18. The enclosure 20 includes a domed roof 31.
The enclosure 20 includes a peripheral fluid inlet 32 and a peripheral fluid outlet 34, each generally extending form the bottom to the top of the enclosure 20 so as to maximize the delivery and the evacuation of fluid, in the form of wind, to and from the blades 18.
More specifically, with reference to Figure 3, the inlet 32 is defined by a lfrst aperture 36 in the enclosure 20 and by two triangular shaped wind barriers 38 and 40 extending outwardly from the enclosure 20. The configuration of the wind barriers 38 an 40 helps decrease turbulence in the aperture 36.
The relative position of the two barriers 38 and 40 and the angles of their inside walls 42 and 44 both create a first wind channel having a gradually decreasing section. This channel helps compress the air before it enl~ers the inlet 32.
As can be seen on Figure 3, the inside walls of the barriers 38 and 40 can optionally be telescopic (see doted line) to provide for an increasE~d delivery of air to the inlet 32.
The generator assembly 14 is also connected to or includes other conventional circuitry for producing electricity from the rotational motion of the shaft 16.

The enclosure 20 includes a peripheral fluid inlet 32 and a peripheral fluid outlet 34, each generally extending form the bottom to the top of the enclosure 20 so as to maximize the delivery and the evacuation of fluid, in the form of wind, to and from the blades 18.
More specifically, with reference to Figure 3, the inlet 32 is defined by a lfrst aperture 36 in the enclosure 20 and by two triangular shaped wind barriers 38 and 40 extending outwardly from the enclosure 20. The configuration of the wind barriers 38 an 40 helps decrease turbulence in the aperture 36.
The relative position of the two barriers 38 and 40 and the angles of their inside walls 42 and 44 both create a first wind channel having a gradually decreasing section. This channel helps compress the air before it enl~ers the inlet 32.
As can be seen on Figure 3, the inside walls of the barriers 38 and 40 can optionally be telescopic (see doted line) to provide for an increasE~d delivery of air to the inlet 32.
The outlet 34 is in the form of a second aperture 43 in the enclosure 20 and includes two flaring side walls 46 and 48 that form a second channel for the air, having a gradually increasing section.
Turning now to Figure 5, the steering assembly 22 will now be described in mare detail. The steering assembly 22 includes a turntable 50 and a driving mechanism 52 for rotating the turntable 50 about the shaft 16.
The turntable 50 rests on a plurality of bearings 54 that are positioned in a circular track 56 so as to assist the rotation of the turntable 50 about the shaft 16. Since the cylindrical enclosure 20 is mounted on top of the turntable 50, the inlet 32 position may vary along a 360 degrees radius.
The driving mechanism 52 includes a drive chain (not shown) secured to the peripheral edge of the turntable 50, two opposite gears 58-60 cooperating with the drive chain and a motor 62 for rotating the turntable 50 via the two gears 58 and 60. Mor specifically, the driving mechanism 52 includes two rotatable shafts 64 and 66 for transferring the rotational forcE~ of the motor 62 to both gears 58 and 60. The driving mechanism also includes and inverter, in the form of a gear assembly 68, for inverting the sense of rotation of the gear 60.
It is to be noted that other driving mechanism can also be provided to rotate the turntable 50 without departing from the spirit of the present invention.

It is to be noted that other driving mechanism can also be provided to rotate the turntable 50 without departing from the spirit of the present invention.
The steering mechanism 22 is connected to the controller 25 via conventional connecting means, such as, for example, electric wires, and is commanded therefrom.
The wind turbine 10 also advantageously includes a fluid current detector 23, in the form of a wind vane connected to the controller 25 via conventional connecting means. Alternatively, the current detector 23 may be replaced by a receiver configured to upload data from a weather station or satellite.
The controller 25 may take many forms, including a personal computer or an electronic circuitry, programmed so as to receive information from the wind vane and to command the operation of the steering mechanism 22 so as to orient the position of the inlet 32 to maximize the delivery of air therein.
In operation, the wind direction is detected by the wind vane and sent to the controller 25 that energizes the motor 62 of the steering mechanism 52 to position the inlet 32 so as to have a maximum delivery to the blades 18.
The air enters the inlet 32 and pushes on the blades 18 that rotates the shaft 16 and then the cogwheel 24, inducing an electrical current in the four generators 26.
The air is rejected in the atmosphere through the outlet 34.
The wind turbine 10 also advantageously includes a fluid current detector 23, in the form of a wind vane connected to the controller 25 via conventional connecting means. Alternatively, the current detector 23 may be replaced by a receiver configured to upload data from a weather station or satellite.

The air is rejected in the atmosphere through the outlet 34.
It is to be noted the inlet 32 is configured and sized so as to maximize the contact of wind on each blade 18 and minimize turbulence. Indeed, the arc length of the first aperture 36 is about the same as the arc length between two adjacent blades 18. The inside wall 44 of the wind barrier 38 also advantageously extend tangentially from the first aperturE~ 36.
It is to be noted that the inlet 32 is also configured and sized so as to compress the air before it contacts the blades.
The steering assembly 52 may advantageously include an emergency brake to stop the blade should certain pre-determined conditions arise.
It is believed within the reach of someone of ordinary skills in the art to modify the wind turbine 10 to operate it in the bottom of the sea, using i:he ocean current as the power fluid.
The fluid powered turbine of the current invention may be used in many applications, such as, for example, electricity generation, water filtration, water pumping, etc.
Although the present invention has been described hereinabove by way of preferred embodiments thereof, it can be modified, without departing from the spirit and nature of the subject invention as defined in the ;appended claims.
