Abstract

Un montaje del disco de turbina de un motor de turbina de gas incluye un disco de turbina, palas de turbina y sellos de pasador. Cada pala de turbina incluye una plataforma con una ranura de sello del lado de presión que se extiende hacia un lado de presión de la plataforma y una ranura de sello del lado de succión que se extiende hacia un del lado de succión de la plataforma. La ranura del sello del lado de presión y la ranura del sello del lado de succión se inclinan, cada una, entre tres y diez grados en la dirección radial en relación con el eje del disco de turbina. El sello del pasador incluye una forma cilíndrica y se ubica dentro de una ranura de sello formada a partir de la ranura de sello del lado de presión y la ranura de sello del lado de succión adyacentes a las palas de turbina.
