del aerogenerador sujeta uno o mas ejes secundarios donde se sujetan las aspas, of the wind turbine holds one or more secondary axes where the blades are held,

las aspas giran según los ejes secundarios the blades rotate according to the secondary axes

Al impactar el viento sobre las las aspas, estas giran según los ejes secundarios y When the wind hits the blades, they rotate along the secondary axes and

estos a su vez según el eje vertical these in turn along the vertical axis

Las aspas son elementos longitudinales donde prima la superficie frente al grosor, The blades are longitudinal elements where the surface prevails over the thickness,

luego estas superficiales tienen dos caras then these superficial ones have two faces

Es un aerogenerador de eje vertical con las aspas colocadas con su dimensión It is a vertical axis wind turbine with blades placed with its dimension

longitudinal colocada horizontalmente horizontally positioned longitudinal

Llamamos buje a una pieza que une dos cuerpos permitiendo el giro de uno We call bushing a piece that joins two bodies allowing the rotation of one

respecto al otro pero no el desplazamiento según el eje de giro with respect to the other but not the displacement according to the axis of rotation

Las aspas colocadas con su dimensión longitudinal horizontal están sujetas mediante al menos un buje a un eje secundario solidario con la parte móvil, unidas rígidamente al eje secundario y el eje secundario unido mediante un buje a la parte móvil del aerogenerador, o las aspas se unen a la parte móvil del aerogenerador mediante un buje siendo el eje secundario un eje de giro. El eje secundario no pasa por su centro de gravedad de modo que en reposo las lamas, quedan colgando, en esta posición se define en el aspa un borde inferior, el que queda abajo, y un borde superior, el que queda arriba The blades placed with their horizontal longitudinal dimension are secured by at least one bushing to a secondary shaft integral with the movable part, rigidly attached to the secondary shaft and the secondary shaft connected by a bushing to the mobile part of the wind turbine, or the blades are joined to the mobile part of the wind turbine by means of a bushing the secondary axis being a rotation axis. The secondary axis does not pass through its center of gravity so that at rest the slats are hanging, in this position a lower edge is defined on the blade, the one that is below, and an upper edge, the one that is above

El giro de los ejes secundarios respecto a la parte móvil del aerogenerador, o bien The rotation of the secondary axes with respect to the moving part of the wind turbine, or

el giro de las aspas respecto al eje secundario, que estaría unido rígidamente a la the rotation of the blades with respect to the secondary axis, which would be rigidly attached to the

parte móvil del aerogenarador, presentara un tope moving part of the wind turbine, will present a cap

Con las aspas colgando en reposo, el giro según el eje secundario que separa el aspa del tope lo definimos negativo y el giro contrario lo definimos positivo With the blades hanging at rest, the rotation along the secondary axis that separates the blade from the top we define it negative and the opposite turn we define it positive

La cara del aspa que se dirige hacia el tope la definimos como cara positiva la cara contraria la definimos como cara negativa We define the face of the blade that goes towards the top as a positive face the opposite face we define as a negative face

El giro del eje vertical del aerogenerador en que con el aspa colgando en reposo la cara positiva se adelanta a la cara negativa lo definimos positivo y el contrario lo definimos como giro negativo The rotation of the vertical axis of the wind turbine in which with the blade hanging at rest the positive face is advanced to the negative face we define it positive and the opposite we define it as a negative turn

Abra al menos dos aspas, colocadas de modo que desde un punto de vista geométrico y mecánico una se reproduce sobre en la otra al girar las aspas según el eje vertical del aerogenerador, por ello visto el aerogenerador en alzado a un lado del eje vertical las aspas muestran su cara positiva y al otro lado muestran su Open at least two blades, positioned so that from a geometric and mechanical point of view one reproduces on the other when the blades rotate along the vertical axis of the wind turbine, therefore seen the wind turbine in elevation on one side of the vertical axis. blades show their positive face and on the other side show their

cara negativa negative face

Al soplar el viento el aspa que presenta al viento su cara negativa inicia un giro positivo, ira hacia la vertical y hacia el tope, o se aprieta contra el tope, mientras que la cara que presenta al viento la cara positiva inicia un giro negativo hacia una posición paralela al viento, iniciándose el giro al empujar el viento la cara negativa del aspa que ha llegado al tope, este aspa al girar llegara vertical hasta estar alineada al viento tras en eje vertical del aerogenerador, mientras el aspa colocada al otro lado del eje llegara horizontal y enfrentada al viento, delante del eje vertical When the wind blows the blade that presents the wind with its negative face starts a positive turn, goes towards the vertical and towards the top, or presses against the top, while the face that presents the positive face to the wind starts a negative turn towards a position parallel to the wind, the turn beginning when the wind pushes the negative side of the blade that has reached the top, this blade will turn vertical until it is aligned with the wind after the vertical axis of the wind turbine, while the blade placed on the other side of the wind axis will reach horizontal and facing the wind, in front of the vertical axis

Aquí se presenta el problema de imprimir un giro positivo al aspa que llega Here is the problem of printing a positive turn to the blade that arrives

horizontal y esta enfrentada al viento y evitar una posición de equilibrio con las horizontal and is facing the wind and avoid a position of balance with the

aspas alineadas al viento wind-bladed blades

Este problema se evita si las aspas presentan conformadas en ellas mismas, en su totalidad o parcialmente, o bien añadidas, unas superficies con estas características viendo el aspa de canto: This problem is avoided if the blades have formed in themselves, in whole or in part, or added, some surfaces with these characteristics seeing the edge of the edge:

1) Turbina tipo 1 la superficie esta conformada por el propio aspa el aspa tendrá 1) Type 1 turbine the surface is conformed by the blade itself the blade will have

esta característica con el aspa colgando el borde externo o mas alejado del eje this feature with the blade hanging the outer edge or farther from the shaft

vertical del aerogenerador estará mas adelantado que el resto del aspa en la vertical wind turbine will be more advanced than the rest of the blade in the

dirección del giro positivo del eje vertical del generador y si el aspa esta horizontal direction of the positive rotation of the vertical axis of the generator and if the blade is horizontal

el borde externo estará mas cerca del suelo que el resto del aspa, es decir la lama the outer edge will be closer to the ground than the rest of the blade, that is the blade

presenta superficies cuyas partes mas alejadas del eje de giro vertical están it presents surfaces whose parts furthest from the axis of vertical rotation are

adelantadas en el sentido de giro positivo del aspa en relación al resto advanced in the direction of positive rotation of the blade in relation to the rest

Pudiendo el aspa en posición vertical tener su borde superior paralelo al eje The blade can be upright having its upper edge parallel to the axis

secundario y su borde inferior con su extremo exterior o mas alejado del eje vertical del aerogenerador mas adelantado que el resto del borde en la dirección del giro positivo del eje vertical del generador y si el aspa esta horizontal el extremo exterior del borde inferior estará mas cerca del suelo que el resto del secondary and its lower edge with its outer end or farther from the vertical axis of the wind turbine more advanced than the rest of the edge in the direction of the positive rotation of the vertical axis of the generator and if the blade is horizontal the outer end of the lower edge will be closer of soil than the rest of the

borde edge

2) Si son superficies añadidas tendrán estas características, si están en la cara positiva del aspa la superficie se ira alejando de la linea imaginaria según el eje secundario según se aleja del eje vertical y si esta en la cara negativa la superficie se ira acercando a la linea imaginaria según el eje secundario según se aleja del eje vertical, si las superficies están añadidas estas superficies tendrán su centro de gravedad al mismo lado del eje secundario que el centro de gravedad de las aspas, es decir la lama presenta superficies cuyas partes mas alejadas del eje de giro vertical están adelantadas en el sentido de giro positivo del aspa en relación al resto 2) If they are added surfaces they will have these characteristics, if they are on the positive side of the blade the surface will move away from the imaginary line along the secondary axis as it moves away from the vertical axis and if it is on the negative side the surface will approach the imaginary line along the secondary axis as it moves away from the vertical axis, if the surfaces are added, these surfaces will have their center of gravity on the same side of the secondary axis as the center of gravity of the blades, that is, the blade has surfaces whose parts are more away from the axis of vertical rotation are advanced in the direction of positive rotation of the blade in relation to the rest


En particular puede haber una superficie sujeta en el extremo exterior del aspa, que pasara de un lado al otro del aspa y la parte que sobresalga del aspa por la cara positiva se ira alejando de la linea imaginaria según el eje secundario según

In particular, there may be a surface attached to the outer end of the blade, which will pass from one side to the other of the blade and the part that protrudes from the blade through the positive side will move away from the imaginary line along the secondary axis according to

se aleje del eje vertical y la parte de la superficie que sobresalga del aspa por la cara negativa se ira alejando de una linea imaginaria según el eje secundario según se acerca al eje vertical move away from the vertical axis and the part of the surface that protrudes from the blade on the negative side will move away from an imaginary line along the secondary axis as it approaches the vertical axis

Con las características de estas superficies ocurre lo siguiente: With the characteristics of these surfaces the following occurs:

1o 15 20 1st 15 20
Según gira el aerogenerador cuando el aspa horizontal se alinea con el viento delante del eje del aerogenerador mostrara una, o mas, superficies en una o dos caras, que se acercan al suelo según se alejan del eje del aerogenerador por lo que el viento imprimirán al aspa un giro positivo, hacia la vertical y el tope, a la vez el otro aspa llega vertical hasta alinearse con el viento tras el eje del aerogenerador mostrara una, o mas, superficies en la cara positiva que se aleja del eje secundario según se aleja del eje vertical del aerogenerador por lo que el viento imprimirá a dicha aspa un giro negativo hacia la horizontalidad Ademas el aspa vertical según gira alrededor del eje vertical, empujada por el viento contra el tope, va presentando a dicho viento una menor superficie, perdiendo eficacia sin embargo si presenta en su cara negativa una, o mas, superficies que se alejan de la linea imaginaria según el eje secundario, según se acercan al eje vertical del aerogenerador el viento impactara sobre esta superficie aumentando la eficacia del aspa As the wind turbine rotates when the horizontal blade is aligned with the wind in front of the wind turbine shaft it will show one, or more, surfaces on one or two faces, which approach the ground as they move away from the wind turbine shaft so the wind will print at a positive turn, towards the vertical and the top, at the same time the other blade arrives vertical until it aligns with the wind after the axis of the wind turbine will show one, or more, surfaces on the positive face that moves away from the secondary axis as it moves away of the vertical axis of the wind turbine so that the wind will print to said blade a negative turn towards horizontality. In addition, the vertical blade as it rotates around the vertical axis, pushed by the wind against the top, presents a smaller surface area, losing efficiency. however, if it has on its negative side one, or more, surfaces that move away from the imaginary line along the secondary axis, as they approach the vertical axis of the wind turbine the wind will impact this surface increasing the efficiency of the blade

Las aspas pueden girar respecto al eje secundario de modo independiente The blades can rotate with respect to the secondary axis independently

25 25
O bien dos aspas son solidarias a un mismo eje secundario, una a cada lado de la parte móvil del aerogenerador y este eje secundario esta unido mediante un buje al la parte móvil del aerogenerador, estas lamas estarán colocadas formando entre si un angulo que puede ser de 90° Or two blades are in solidarity with the same secondary axis, one on each side of the mobile part of the wind turbine and this secondary axis is connected by a bushing to the mobile part of the wind turbine, these slats will be placed forming an angle that can be 90 °

El conjunto formado por dos aspas solidarias al mismo eje secundario, en reposo, queda formando un angulo con la vertical, estando el centro de gravedad en la vertical del eje de revoluciones secundario, si el angulo entre las aspas es de 90°, en reposo forman 45° con la vertical The set formed by two blades in solidarity with the same secondary axis, at rest, forms an angle with the vertical, the center of gravity being in the vertical of the secondary speed axis, if the angle between the blades is 90 °, at rest form 45 ° with the vertical

35 35
Las aspas pueden tener forma de canal, la cara negativa sera la superficie interna del canal y la cara positiva sera la superficie externa del canal The blades can be shaped like a channel, the negative side will be the internal surface of the channel and the positive side will be the external surface of the channel

vertical vertical

En particular (Aeroturbina tipo 5) FIG 16 a FIG 18 puede haber una superficie (17) sujeta en el extremo exterior del aspa, que pasara de un lado al otro del aspa y la parte que sobresalga del aspa por la cara positiva (18) se ira alejando (19) de la linea imaginaria según el eje secundario según se aleje del eje vertical y la parte de la superficie que sobresalga del aspa por la cara negativa (20) se ira alejando (21) de una linea imaginaria según el eje secundario según se acerca al eje vertical, es decir la lama presenta una superficie en su extremo exterior que pasa de la cara negativa a la cara positiva cuyas partes mas alejadas del eje de giro vertical están adelantadas en el sentido de giro positivo del aspa en relación al resto In particular (Type 5 aeroturbine) FIG 16 to FIG 18 there may be a surface (17) attached at the outer end of the blade, which will pass from one side to the other of the blade and the part that protrudes from the blade on the positive side (18) it will move away (19) from the imaginary line along the secondary axis as it moves away from the vertical axis and the part of the surface that protrudes from the blade on the negative side (20) will move away (21) from an imaginary line along the axis secondary as it approaches the vertical axis, that is, the blade has a surface at its outer end that passes from the negative side to the positive side whose parts furthest from the vertical axis of rotation are advanced in the direction of positive rotation of the blade in relation to to the rest

Con las características de estas superficies ocurre lo siguiente: With the characteristics of these surfaces the following occurs:

Según gira el aerogenerador cuando el aspa horizontal se alinea con el viento delante del eje del aerogenerador FIG 18 mostrara una, o mas, superficies (22) en una o dos caras, que se acercan al suelo (23) según se alejan del eje del aerogenerador por lo que el viento imprimirán al aspa (4.1) un giro positivo (24), hacia la vertical y el tope, a la vez FIG 18 el otro aspa (4.2) llega vertical hasta alinearse con el viento tras el eje del aerogenerador mostrara una, o mas, superficies (25) en una o dos caras que se adelantan (26) en el sentido de giro del eje vertical según se aleja del eje vertical del aerogenerador por lo que el viento imprimirá a dicha aspa un giro negativo (27) hacia la horizontalidad As the wind turbine rotates when the horizontal blade is aligned with the wind in front of the axis of the wind turbine FIG 18 will show one, or more, surfaces (22) on one or two faces, which approach the ground (23) as they move away from the axis of the wind turbine so that the wind will print to the blade (4.1) a positive turn (24), towards the vertical and the stop, at the same time FIG 18 the other blade (4.2) arrives vertical until it aligns with the wind after the axis of the wind turbine will show one, or more, surfaces (25) on one or two faces that advance (26) in the direction of rotation of the vertical axis as it moves away from the vertical axis of the wind turbine so that the wind will print a negative turn to said blade (27 ) towards horizontality

Ademas el aspa vertical según gira alrededor del eje vertical, empujada por el viento contra el tope, va presentando a dicho viento una menor superficie, perdiendo eficacia sin embargo si presenta en su cara negativa una, o mas, superficies que se alejan de la linea imaginaria según el eje secundario, según se acercan al eje vertical del aerogenerador el viento impactara sobre esta superficie aumentando la eficacia del aspa In addition, the vertical blade as it rotates around the vertical axis, pushed by the wind against the stop, is presenting a smaller surface area to said wind, however, if it has one or more surfaces on the negative side that move away from the line Imaginary according to the secondary axis, as they approach the vertical axis of the wind turbine the wind will impact on this surface increasing the efficiency of the blade

Las aspas pueden girar respecto al eje secundario de modo independiente The blades can rotate with respect to the secondary axis independently

O bien dos aspas son solidarias a un mismo eje secundario, una a cada lado de la parte móvil del aerogenerador y este eje secundario esta unido mediante un buje al la parte móvil del aerogenerador, estas lamas estarán colocadas formando entre si un angulo que puede ser de 90° Or two blades are in solidarity with the same secondary axis, one on each side of the mobile part of the wind turbine and this secondary axis is connected by a bushing to the mobile part of the wind turbine, these slats will be placed forming an angle that can be 90 °


El conjunto formado por dos aspas solidarias al mismo eje secundario, en reposo, queda formando un angulo con la vertical, estando el centro de gravedad en la vertical del eje de revoluciones secundario, si el angulo entre las aspas es de 90°, en reposo forman 45° con la vertical

The set formed by two blades in solidarity with the same secondary axis, at rest, forms an angle with the vertical, the center of gravity being in the vertical of the secondary speed axis, if the angle between the blades is 90 °, at rest form 45 ° with the vertical


Las aspas (aeroturbina tipo 6) pueden tener forma de canal, la cara negativa sera la superficie interna del canal y la cara positiva sera la superficie externa del canal

The blades (aeroturbine type 6) can have a channel shape, the negative side will be the internal surface of the channel and the positive side will be the external surface of the channel
