Abstract

Una pala de turbina incluye una porción de superficie aerodinámica, un pasaje de enfriamiento que se extiende en una dirección de altura de pala dentro de la porción de superficie aerodinámica, y una pluralidad de orificios de enfriamiento formados en una parte de borde trasero de la porción de superficie aerodinámica que se arregla en la dirección de altura de pala, la pluralidad de orificios de enfriamiento que se comunican con el pasaje de enfriamiento y se abren a una superficie de la porción de superficie aerodinámica en la parte de borde trasero. Se cumple una relación de d_up <d_mid <d_down, donde d_mid es un índice que indica densidades de apertura de los orificios de enfriamiento en una región central que incluye una posición intermedia entre un primer extremo y un segundo extremo de la porción de superficie aerodinámica en la dirección de altura de pala, d_up es un índice en una región colocada corriente arriba de un flujo de un medio de enfriamiento en el pasaje de enfriamiento de la región central en la dirección de altura de pala, y d_down es un índice en una región colocada corriente abajo del flujo del medio de enfriamiento de la región central en la dirección de altura de pala.
