Definitions

• the present invention relates to a turbine operable either through the force of a MOTEU r fluid (wind, water, other fluid), either through a temperature difference between both ends of the turbine (e.g., the difference in air temperature at ground level and at a higher altitude).
• a MOTEU r fluid wind, water, other fluid
• This turbine, object of the invention can therefore be used as an atmospheric turbine, that is to say a wind turbine, a hydraulic turbine, or a thermal turbine, or, in a mixed manner by combination between these different modes.
• the ideal wind turbine would therefore be a solid, stable, heavy wind turbine, turning quickly but not racing, starting in weak wind, with vertical or oblique axis allowing the installation of the generator close to the ground, with simple and therefore economical technology. during manufacture, with reduced maintenance, with larger surfaces exposed to the wind on one side of the axis of rotation relative to the other in the case where the axis is vertical or oc'ic, modular to facilitate assembly and allow to decrease or increase the sur ace of the wind turbine in a later time.
• Turbine (1) composed of two (or more) helical surfaces (3,4) arranged symmetrically with respect to an axis of rotation (2), itself being the axis of the cylinder in which these helical surfaces (3.4) are register. Each of these helical surfaces (3,4) wraps at least 180 * (fig. 3 and 4) around the axis of rotation (2) There is no theoretical maximum.
• Each of the helical surfaces (3.4) is bordered on the outside by a gutter, the peripheral gutter (5).
• Different profiles can be given to this peripheral gutter (5) with or without flange (6), with or without blades (10).
• the profile of the helical surfaces (3,4) consists of planar (fig. 8) or curved (fig. 8) surfaces whose angle formed by each of them with the axis of rotation (2) can be variable and constitutes a continuous set either of "steps / risers", or of "undulations” thus forming kinds of gutters (7) flared towards the outside, placed perpendicular or oblique with respect to the axis of rotation (2.) ( fig.9). Their number can vary from 1 to oo. In the latter case, the helical surface (3). (4) will be a smooth surface (fig. 10).
• the lower profile of the helical surfaces (3,4) as well as that of the peripheral gutters (5) may be different from the upper profile.
• an upper profile in "steps / counter-steps" and a smooth lower profile which will give a better performance in the case of the use of the turbine (1) as a wind turbine with axis of rotation (2) vertical, in addition to other jobs.
• the axis of rotation (2) of the turbine (1) can be placed vertically, obliquely, or ⁇ horizontally
• peripheral gutters (5) can be directed towards either end of the axis of rotation (?)
• the gutters (7) formed by the helical surfaces (3,4) are intended to channel the working fluid towards the periphery of these surfaces, that is to say towards the peripheral gutters (5), where the effect of a same thrust is at its maximum, phenomenon amplified by centrifugal force as soon as the turbine (1,) sets in motion
• the helical surfaces (3,4) being bordered externally by a peripheral gutter (5) continues, the working fluid arrives with force in this peripheral gutter (5) and, not being able to escape towards the outside of the turbine (1), it pushes on the external edge of this peripheral gutter (5) and makes turn the turbine (1)
• This peripheral gutter ( 5) may or may not have a rim (6) intended if there is to retain even more the working fluid in the peripheral gutter (5).
• the helical shape coupled with the existence of a peripheral gutter (5) which borders it causes a phenomenon of air vortex which continues to push on surfaces which are no longer exposed to the working fluid.
• a large part of the working fluid ends up at the top of the turbine (1).
• the helical surface (3) (4) is smooth, the same phenomenon has occurred.
• the same operating principle applies when using this turbine (1) as a thermal turbine (fig 11) indeed, the fluid moves from the hottest zone to the coldest zone
• the peripheral channels (5) can be directed in the same direction as la.direction the thrust of the working fluid (8) (fig.12) or in opposite direction (Fig 11) and obliquely pa r report celle- one way or the other, depending on the terms of employment
• the axis of rotation (2) can be placed perpendicularly, obliquely, or parallel to the direction of the thrust of the working fluid (8), according to the instructions for use. For example :
• the oblique position gives the best performance in the case of use in an atmospheric and / or hydraulic turbine.
• the ideal obliquity depends on the ratio between the height and the diameter of the cylinder in which the helical surfaces (3.4) composing the turbine (1) are inscribed (fig. 2,4,7).
• peripheral gutters (5) will be directed in the opposite direction to the direction of the thrust of the working fluid (8) (fig.11).
• the peripheral gutters (5) should preferably be directed in the same direction approximately that the direction of the thrust of the thermal working fluid (8) if the helical surfaces (3.4) have a profile making existing openings (9) at the junction between these surfaces and the peripheral gutters (5) which border them.
• the thermal working fluid then joins the atmospheric working fluid (wind) in the peripheral gutter (5) passing through these openings (9).
• the peripheral gutter (5) will be split, each placed in the opposite direction to the other.
• the direction of rotation of the turbine (1) changes according to the position of the axis of rotation (2) relative to the direction of the thrust of the working fluid (8) as well as according to the direction of the screwing pitch (fig. 13 ).
• the turbine (1) In the case where the axis of rotation (2) of the turbine (1) is placed perpendicular to the direction of the thrust of the working fluid (8), it is not necessary to provide an orientation system, the turbine (1) being in this case multidirectional (f ⁇ g.13, c). In the case where the axis of rotation (2) of the turbine (1) is placed obliquely to the direction of the thrust of the working fluid (8), it is not necessary to provide an orientation system because the turbine ( 1) self-o ⁇ ente so as to place the top of the axis of rotation (2) towards the origin of the thrust of the working fluid (8) (fig.13, a).
• An orientation system is only necessary in this case if it is to be the bottom of the axis of rotation (2) which is oriented towards the origin of the thrust of the working fluid (8), for example in I use in a mixed thermal and atmospheric turbine. In this case also, a pivoting system for the entire turbine (1) must be provided
• This device is not necessary if the axis of rotation (2) is placed vertically (fig 13, d) and therefore the direction of the thrust of the working fluid (8) is from bottom to top (example turbine vertical axis) or from top to bottom.
• This turbine (1) can be used in a mixed manner, in time and / or in space and / or simultaneously, that is to say as an atmospheric and / or hydraulic and / or thermal turbine. Advantages linked to the invention (Turbine (1) described above)
• this turbine (I) can be manufactured in different materials, from very light to very heavy, in particular canvas or the like on a wooden, plastic, metal frame, etc. as well as in molded synthetic material or not, without forget about metal.
• peripheral gutters (5) can be an integral part of the modules or be added during assembly.
• the realization by modules also allows to be able to modulate in time the size of the turbine? ⁇ the axis is expected to be quite long
• the axis of rotation (2) can have a large diameter without disadvantages II can therefore be constituted by a movable outer tube, integral with the helical surfaces, pivoting around a fixed tube of smaller diameter, these two tubes being provided with the devices necessary to constitute in themselves a generator
• the same turbine model (1) can be used as an atmospheric turbine, that is to say wind turbine and / or hydraulic turbine and / or thermal turbine
• This turbine (1) is multidirectional in the case where the axis of rotation (2) is placed perpendicular to the direction of the thrust of the working fluid (8). It is self-orientating in the case where the axis of rotation (2) is placed parallel or obliquely from the front (fig. 13, d, a) relative to the direction of the thrust of the working fluid (8)
• the generator can be placed close to the ground if the axis is either vertical or oblique
• the direction of rotation in this case is the same as the direction of the screwing pitch.
• the same figures looked at in reverse represent views of the turbine (1) back to the working fluid, the top of the axis of rotation (2) being tilted obliquely backwards by 17.74 * relative to the vertical.
• the direction of rotation in this case is opposite to the direction of the screwing pitch
• This specific characteristic of the oblique positioning of the axis of rotation (2) of the turbine (1) represents an enormous advantage compared to the positioning perpendicular to the direction of the thrust of the working fluid (8) (fig 1, 3 and 6), working fluid which in this case meets two surfaces, to the left and to the right of the axis of rotation (2), identical from the point of view of the magnitude of their surface
• the helical shape and the possible differences in profiles generate the rotational movement of the turbine (l), amplified by the peripheral gutters (5).
• the oblique positioning of the axis of rotation (2) causes the turbine (1) to self-align so as to place the top of the axis towards the origin of the thrust of the working fluid, the direction of rotation being in this case the same as the direction of the screwing pitch
• the direction of rotation can be changed simply by changing the orientation of the turbine (1) so as to place the bottom of the axis towards the origin of the thrust of the working fluid This can be done by the exit of a drift for example
• the two ends of the axis of rotation can be mounted free, each on a walkway, or, one of these two ends only free and the other fixed.

• thermal turbines operating thanks to a temperature difference between the two ends of the turbine (1), they can be made in large dimensions to exploit the temperature difference between the air on the ground and the colder air of the higher layers of the atmosphere.
• this turbine (1) is opposite to the direction of rotation of this same turbine used in wind turbines, except in the case where it is placed at the top of a hill. It must therefore be placed in a cylinder which will protect it from the action of the wind and at the same time create an aspiration of the fluid upwards, which will increase the yield.
• this cylinder can be opened on 1/4 of a turn, the wind then acting on half of the turbine (right half looking at Figures 1, 3,5 and 6 and considering that 'we have the wind in the back, left half under the same conditions if the screwing pitch is reversed compared to Figures 1, 3.5 and 6.
• This cylinder must have an orientation system (drift).
• the temperature on the ground can be increased thanks to a set of mirrors concentrating the solar radiation for example on a metal plate placed under the turbine
• Figures 2,4 and . 7 looked at .
