Abstract
La presente invención se refiere a una turbina de gas que comprende un rotor (11) y un álabe (10) con una superficie de sustentación (14), una raíz (12) del álabe provista para que sea recibida removiblemente por una muesca (31) en el rotor (11), y un núcleo (18) del álabe, hueco, que se extiende entre la raíz (12) del álabe y la punta (15) del álabe para el flujo de un fluido de enfriamiento, que se introduce al núcleo (18) del álabe a través de una entrada (20) del álabe en la raíz (12), y es suministrado por medio de un orificio (23) del rotor, que se extiende a través del rotor (11) y está en comunicación de fluido con la entrada (20) del álabe, por lo cual la entrada (20) tiene un área de sección transversal que excede el área de sección transversal del orificio (23) del rotor en al menos una dirección, el orificio del rotor tiene una salida (24) del orificio del rotor con la forma del difusor, de tal modo que el área de sección transversal de la salida (24) del orificio del rotor en la interconexión entre el orificio (23) del rotor y la entrada (20) cubra el área de sección transversal de la entrada (20).
