Abstract
Estructura de carcasa de una turbomáquina con una pared de carcasa (1) exterior y una pared de carcasa interior, que rodean separadas una de la otra el canal de flujo de la turbomáquina de manera circundante por el lado exterior del canal de flujo, estando formada en la zona de los álabes móviles de la turbomáquina, que giran alrededor de un eje axial de la turbomáquina, la pared de carcasa interior de la estructura de carcasa por una OAS (2), habiendo configurada entre la pared de carcasa (1) exterior y la OAS (2) una pantalla de protección térmica (9), la cual está en contacto con la OAS y comprende un elemento de protección térmica (11) plano, y habiendo dispuesto en dirección axial en paralelo con respecto al eje axial junto a la OAS en la pared de carcasa interior, un segmento de álabe fijo (6), el cual está asegurado en su posición axial por un anillo de seguridad (8), el cual está dispuesto en la pared de carcasa exterior, caracterizada por que la pantalla de protección térmica presenta en dirección perimetral varios separadores (10) separados unos de otros en dirección perimetral, los cuales se encuentran adicionalmente a y en dirección radial fuera del elemento de protección térmica (11) y superan la separación entre el anillo de seguridad (8) del segmento de álabe fijo y el elemento de protección térmica (11), y presentan respectivamente una superficie de contacto (12) para el anillo de seguridad (8) del segmento de álabe fijo, estando prevista en los separadores (10) a modo de prolongación de la superficie de contacto (12) una sección (13) curvada, la cual se extiende en dirección del segmento de álabe fijo (6) y está curvada en dirección del elemento de protección térmica (11).
