- -
- Requieren de un gran par de arranque,
- -
- Requieren de un sistema de frenado ante la presencia de grandes vientos.
- -
- Requieren de la orientación o desorientación con respecto a los vientos dominantes.
- -
- Requieren de la utilización única de vientos laminares.
- -
- Requieren disponerse a grandes alturas.
- -
- Para que resulten rentables, deben materializarse en la práctica en máquinas de grandes dimensiones.
álabes.
- \bullet
- Ambos álabes trabajan de forma simultanea a sustentación y arrastre, independientemente de la posición que ocupen en el rotor y del ángulo de ataque del fluido predominante.
- \bullet
- Estos perfiles están inclinados, es decir, desfasados sus extremos rotacionalmente, entre las bases de apoyo inferior y superior, y en vertical hacia la dirección de giro del rotor, con lo que se obtiene una mayor permanencia de contacto del álabe con el fluido y a favor, eliminando el salto al pasar la acción del fluido de un álabe, al vacío entre ambos y al otro álabe; se eliminan los llamados "caballitos", realizando de esta manera un funcionamiento mucho más regular, continuo y un arranque más suave, precisando menor potencia para iniciar el movimien- to.
- \bullet
- Ambos perfiles alares decrecen la cuerda, a medida que avanza su proyección vertical en relación aproximada a un 5%, no siendo limitativo, esto confiere, al fluido circulante en la parte cóncava de un efecto cuchara, que provoca un efecto venturi, y acelera el fluido en su interior, tendiéndolo a desalojar más rápidamente.
- \bullet
- A medida que asciende su proyección en vertical, con todo lo anteriormente citado a la vez, disminuye la cuerda del perfil, como se ha dicho, y además se revira la sección, manteniendo las características básicas del perfil madre, con lo que el ángulo que avanza la sección, en el sentido del giro del rotor, no es el que avanza el ángulo de ataque, sino que este se minimiza en un contragiro que hace la misma cuerda en su revirado en sentido contrario, con lo este hace permanecer mayor espacio y tiempo expuesta a unas mejores condiciones de optimización del fluido.
- \bullet
- La configuración y forma final de cada álabe o perfil alar, es la resultante, en cada caso, de todo lo anterior integrado con que el momento torsor generado en cada sección infinitesimal, ha de ser constante; y de esta manera no se generen fatigas y tensiones internas en los citados perfiles alares, y así trabaja todo el perfil en idénticas condiciones.
- \bullet
- Por ello en su proyección en vertical, el borde de ataque presenta un desplazamiento progresivo del perfil, hacia dentro y fuera del rotor, siguiendo una suave curva, de esta manera el borde superior del álabe esta a menor distancia del centro del eje del rotor que el borde inferior de la mismo, para compensar momentos.
- \bullet
- Uno se prepara para sacar el máximo rendimiento a las fuerzas de arrastre, el Alfa.
- \bullet
- Y el otro, el Beta, se prepara para obtener el máximo rendimiento a las fuerzas de sustentación del fluido.
