DESCRIPTION
Variable profile candle.
Technical sector of the invention
The present invention relates to a variable profile sail, configurable between a folded non-operative position, and an unfolded operative position, in which they determine the profile of the sail and therefore the aerodynamic surface of contact with the wind.
The inflatable profile sail of the present invention finds particular application as a constituent element of the energy conversion system, and more specifically to a system to convert the force of the wind into seas and oceans into electric energy and non-fossil fuel, thanks to the electrolysis of seawater in H2 and / or O2.
Background of the invention
It is known in fluid mechanics that the efficiency of cloth sails is lower than the wing of aircraft wings. In these, the difference between the strength of support and the weight allows the plane to fly, thanks to the fact that the layer is air-dynamic in the air does not come off the profile. On the contrary, in conventional sails in the naval sector, it is the thrust of the wind that swells the sail and produces, by thrust, a resulting force that allows the vessel or ship to advance.
For a long time a sail for water navigation has been desired that presents the advantages of aviation wings. To this end, there have been numerous attempts to provide rigid sails of aeronautical aerodynamic profile.
Among them are the Flettner type rotors already described in 1926 by Anton Flettner (FLETTNER, Anton Mein Weg zum Rotor, Leipzig (Kohler & Amelang, 1926)), already mentioned, for example, in European patent document EP 040 597 .
WO2004024556 describes a rigid sail that is composed of two parts that can rotate relatively along a vertical axis to determine the intrados and the extractions of a candle as an aerodynamic profile of those used for the wings of the aeronautical technique.
WO0189923 describes a rigid sail with an articulated aerodynamic profile comprising three vertical elements (or modules), each of which is formed by three horizontal elements (or sections) mutually articulated or extracted from a rigid wing or sail.
Patent FR2648426 describes a wing composed of a rigid part and a flexible part that is retracted inside a housing of the rigid part, allowing different aerodynamic configurations.
Patent US7146918 describes a system for generating electricity and hydrogen, from seawater and wind energy, in floating systems in the water comprising rigid sails.

The problem presented by the generation system of US7146918 is that the candles are difficult to operate, control and regulate, and with this the production of energy and H2 loses performance and predictability. For example, an important problem is that if the wind turns 180 ° then an operation to turn the sails becomes necessary, which can be difficult and dangerous.
Despite this profusion of attempts, of which only illustrative examples have been listed, a versatile, economical and easy-to-operate device has not been achieved to date.
Document EP2202144A1 describes a rigid sail with a configurable profile, with elastic enclosures, attached to the corresponding wall in at least one area near said extreme edge and means for generating and feeding pressurized air and ford to inflate and deflate the candles to modify at will the profile of the candle. This candle provides a solution to this demand.
US8601966 describes aerodynamic profile sails, which fold and unfold as an accordion, and which provide another efficient and high-performance solution in the production of hydrogen and other chemical species of high enthalpy content. The candles form a set formed by pairs of opposite candles, each of which comprises extensible masts, sections that move longitudinally on said masts and panels, articulated to the sections and with each other, that make up the lateral surface of each candle. Such panels are operative between two positions: an unfolded operative position, in which they are essentially coplanar and longitudinally aligned in an essentially vertical direction; and a folded rest position, in which they are stacked as a bellows, together with the essentially horizontal sections.
Notwithstanding the efficiency and versatility of the sail of US8601966, the folding mode could have mechanical and operational problems, when it comes to folding or unfolding very quickly, for example due to changes in weather conditions.
One of the purposes of the present invention is to provide a simultaneous solution to the above problems and disadvantages.
Explanation of the invention
For this purpose, the object of the invention is a variable profile sail, of novel concept and functionality, which in essence is characterized by comprising at least one inflatable and rigidizable sail element, operable by means of inflation and stiffening, between a retracted position, corresponding said retracted non-operative position, and said deployed operative position, in which the configurable profile sail is inflated and rigid.
According to another feature of the present invention, the profile of the sail is divided into sections on both sides of an axis, and comprises a support structure, on which said inflatable sail elements are arranged, which are constituted by bags inflatables, operable by said inflation and stiffening means.

The sail can rotate around the axis, guided in its lower part on a carriage around circular glues.
The axis can comprise a triangular reinforcement column, to give more support to the support structure.
According to another characteristic of the candle according to the invention, it is covered externally with a technical fabric that adapts to the shape of the profile of the candle at all times, and which encloses the set of inflatable bags.
Preferably, the profile of the sail is in the plane wing profile.

The invention is based on the combination of wind speed with high water density, which makes the performance much higher than that of any other wind-based system as a primary energy source.
It is mainly a vessel 1 specially designed for the production of hydrogen (and / or oxygen), obtained from the electrolysis of sea or lake water, which incorporates the sails 2 of the invention.
In the drawings it can be seen that the system for the production of hydrogen from seawater, according to the present invention, comprises:
- a vessel 1, designed for and in charge of supporting all the necessary structural loads and housing the storage system inside;
- provided with sails 2, responsible for propelling the vessel so that it acquires speed;
- submerged turbines 3, which rotate because of the relative speed between the boat and the water and generate mechanical energy, feeding in turn the electrolysis equipment and the auxiliary equipment. The turbines 3 rotate because of the relative speed between the vessel 1 and the water and generate mechanical energy, in turn feeding the generation equipment of H2 5 and the auxiliary equipment of the vessel 1;
- an electric generator 4 adapted to convert turbines 3 into electricity rotation;
- an on-board hydrogen generation system 5 to produce H2 and O2 from the electrical energy generated by the generator 4;
- storage media 6, for example based on high pressure H2 and O2 ISO containers (30 bar, 300 bar or higher).
According to the present invention, different variants for the H2 generation system are possible, including, and not limited to:
- by chemical electroactivation (ECAS) of seawater in ECAS 11 cartridges through the addition of an electrolyte. In this case it can be fed with an additional electrolyte, or the salinity of seawater itself may suffice; Y
- a system by electrolysis of water through membranes of filtration, microfiltration and / or ultrafiltration elements 10.
The process in which H2 and O2 is generated and stored is as follows:
- Ship 1 leaves the port with the use of an engine (not shown), either conventional or hydrogen fuel cell and goes to an area with high intensity winds.
- Once there, ship 1 turns off the engine and sails, using the sails 2 deployed, following the direction of maximum wind intensity just to

Acquire a high speed. The higher the speed of vessel 1, the greater the production of hydrogen and oxygen.
- In this process, the ship acquires relative speed with the sea, which is used to generate mechanical energy thanks to submerged turbines 3.
- With this mechanical energy, transformed into electricity, the hydrogen generation systems 5 and the auxiliary equipment to perform the electrolysis or chemical electroactivation (ECA) of the previously conditioned water will be fed, separating it into hydrogen and oxygen or other chemical species in the case of the RCT (for example Cl and its compounds).
- The gases will be stored on board under pressure, in a gaseous state at first or by chemical or cryogenic storage, in gas storage means 6, provided in the illustrated example (Figs 1 and 2), of tanks 7 of hydrogen, oxygen , etc.
- When tanks 7 or chemical storage components (cells) are full, ship 1 returns to the port to unload and restart the process.
Ideally, it is expected to work with standard pressure storage in ISO containers, which can later be unloaded at any port without the need for special infrastructure, although it is expected that other methods of storage can be used, such as large spherical tanks or chemical storage elements (cells ).
According to the invention, the sails 2 are stiffened and configurable profile sails between a retracted non-operative position (Fig. 3), and an unfolded operative position (Figs. 1, 4 and 5), in which they determine the profile of the sail 2 and therefore the aerodynamic surface of contact with the wind. Preferably, the sails (2) in their inflated and stiffened form acquire an airplane wing profile.
Each sail 2 is formed by profile elements 100 (Figs. 3, 4 and 5), divided into equal and pivotal sections 21, 22, on a tubular articulation 26, arranged on both sides of an axis 20, and comprise a support structure 23, by way of celosla, on which are arranged sail elements 24, constituted by inflatable bags 24, individually or collectively operable, by inflation means 30, between a deflated position, corresponding to the retracted position, and an inflated and rigid position, corresponding to the deployed position, in which they determine the profile of the sail 2 and therefore the aerodynamic surface of contact with the wind.
The structure 23 in lattice, which has the shape of the trailing edge of the aerodynamic profile, for when the inflatables have to be assembled, it is not necessary to work with those of one half of the profile and they can be completely inflated.
Once both sections 21 and 22 of the profile elements 100 are fixed and anchored to each other, and the profile elements 100 are fixed together, the sails 2 can rotate around the axis 20 guided in its lower and upper part on a bearing carriage 9 around circular glues 12 of the deck 13 of the vessel 1, and on its upper rotating axis.

The central axis 20 and the sections 21 and 22 in contact with it, transmits the efforts to the whole ship and receives the mounting of the support structure 23 in the celosla. All profile elements 100 are anchored to said central axis 20.
There are vertical elements 27 on the two edges of the support structure that act as a glutton for an outer lining 28 (Figs. 4 and 8), which can be folded either under the structure, on deck, or on the top . This outer lining 28 may be a technical fabric that adapts to the shape of the profile of the candle 2 at any time, and that encloses the set of inflatable bags 24. For clarity, in Figs. 1 and 5 show candles 2 without outer lining 28.
The axis 20 of the embodiment mode illustrated, comprises a triangular reinforcement column 32, to give more support to the support structure 23 in lattice. Figs. 2 to 5. The triangular reinforcement column 32 can be replaced by an element of a different shape, but with the same function.
As an additional point, the whole set of candles 2 can be joined by an upper gangway 8 (Fig. 1), which gives the assembly more inertia.
As mentioned, to form the shape of the aerodynamic profile, the assembly has a series of inflatable sail elements 24 that can be swollen at will by means of inflation 30, by pressurized air through pipes and common pressure systems distributed throughout the support structure 23 in celosla of the candle 2, being able to adopt with this system the candle 2 different shapes and configurations at each moment. A non-limiting example of the operation of the inflatable sail elements 24 is described below, with particular reference to Figs. 6 and 7:
The inflation system 30 for configuring adaptable profiles consists of inflatable bags 24, preferably of plastic material (for example PVC), provided with an inner liner 25.
Said inflatable bag 24 is tensioned through motorized rollers 31 that collect or release the inflatable bag 24, while the inner lining 25, which is attached to the inflatable bag 24 by means of a heat-welded joint or the like, has an injection tube 32 of pressurized air, said tube will be fixed to a frame of the support structure 23 in lattice, which will keep it fixed in a position and also acts as a support to hold an inner frame 33.
This inner frame 33 is arranged inside the inflatable bag 24 but outside the liner 25 and has its analogue in an outer frame 34, which exert a guiding function, being able to tension and release "fabric" from the inflatable bag 24. The outer frame 34 will be fixed to the general structure as well as the inner frame 33. Said frame gives stability, positioning, and rigidity to the tangential stresses that the wind can generate.
The sail 2 formed from the inflatable bags 24 is also stiffened. For this purpose, the inflatable bag 24 has some stiffening means for swelling with preformed seams 29 (Fig. 7), so that the inflatable bag 24 grows or decreases in volume, but with a rigid and designed shape of beforehand, in the same way as the well-known car airbag devices. In Figs. 4 and 5 it can be clearly seen how the inflatable bags 24 are of each other in different shapes and maximum volumes, once the inflated and rigid deployed operating position has been acquired.
With the invention the creation of configurable and adaptable volumes is solved, for any system that needs this possibility, such as configurable profile sails, or wind turbine blades.
5 Those skilled in the art will appreciate that the sails 2 of the invention system have a complete symmetric duality, the sails 2 can already be set to one side or the other, and according to variable volumes, making it unnecessary to rotate 180 ° in case the wind Come from the opposite side. Likewise, for certain variations of the wind direction or speed, the vessel of the system of the present invention does not require to vary its direction.
10
Described sufficiently the nature of the present invention, as well as the way of putting it into practice, it is stated that everything that does not alter, change or modify its fundamental principle is subject to variations in detail.
15 In this sense, the stiffening and configurable profile sails 2 of the present invention can adopt other embodiments different from the one explained in relation to the preferred embodiment based on inflatable elements or bags 24. The sail 1 can also find applications other than the one described here concerning its application in a vessel 1 for a hydrogen production system.

Similarly, the number of profile elements 100, as well as that of sail elements (or inflatable bags) 24, can be any, including the unit, being within the scope of protection of the claims.
