Abstract

Un aparato de escape (10) para una turbina de gas (1) incluye un conducto anular (12) con una pluralidad de puntales (18) extendiéndose al menos desde una pared de conducto exterior (14) a una pared de conducto interior (16) del conducto anular (12); cada puntal (18) está encapsulado en un blindaje de puntal respectivo (20); una interfaz (22, 24) del blindaje de puntal (20) con una pared de conducto respectiva (14, 16) incluye al menos un collar (26) extendiéndose a lo largo de una longitud parcial del perímetro del blindaje de puntal (20) en la interfaz respectiva (22, 24); el collar (26) incluye una primera sección (32) extendiéndose radialmente y estando alineada con el blindaje de puntal (26), y una segunda sección (34) orientada a un ángulo a la primera sección (32) y estando alineada con la pared de conducto respectiva (14, 16); la primera sección (32) está unida en el blindaje de puntal (20) a lo largo de una primera junta (42) y la segunda sección (34) está unida a la pared de conducto respectiva (14, 16) a lo largo de una segunda junta (44); una intersección (40) de la primera y segunda secciones (32, 34) es formada por una curva suave definida por un radio configurado para distribuir tensiones en la interfaz respectiva (22, 24).
