Abstract

La presente invención consiste de un aditamento neumático para limitación de fuerzas aerodinámicas en palas de turbinas eólicas de eje horizontal, que se compone principalmente de una junta inflable o microtab, una tapa rígida de forma específica que ensambla sobre una cavidad externa a la superficie de succión de la pala y un sistema de alimentación neumático. La incorporación de una junta inflable o microtab en el aditamento neumático para limitación de fuerzas en palas de turbinas eólicas de eje horizontal, no genera variación de fuerzas centrífugas debido a que su activación no implica movimiento de masas significativas, además dicha junta inflable o microtab permite evitar el paso de polvo, humedad o suciedad en general al interior de la pala. Cabe destacar que el mantenimiento se realiza sin manipular internamente la pala y desmontando de manera sencilla, lo cual permite reducir riesgos al personal a cargo de las maniobras. Con el uso de la presente invención se logra limitar las fuerzas aerodinámicas de diseño, específicamente la fuerza de sustentación y la fuerza axial a la que es sometida la pala durante su operación, lo cual permite aumentar el tiempo de vida útil de los componentes de la turbina debido a la reducción de la magnitud de dichas fuerzas durante la operación de la turbina eólica.
