Abstract

DISPOSIÇÃO DE ALETA DIRETRIZ DE UMA TURBOMÁQUINA. A presente invenção refere-se a uma disposição de aleta diretriz de uma turbomáquina (4), especialmente de uma turbina a gás, abrangendo: ao menos um suporte de aleta diretriz (2), que é fixado a uma caixa (5) de uma turbomáquina (4), várias aletas diretrizes (3), que estão fixadas ao suporte de aleta diretriz (2) e dispostas lado a lado em direção periférica, sendo que cada aleta diretriz (3) apresenta uma plataforma (6), abrangendo um primeiro segmento de trava (8) e axialmente distanciado do mesmo um segundo segmento de trava (9), sendo que o suporte de aleta diretriz (2) apresenta um primeiro segmento de suporte (12) e axialmente distanciado do mesmo um segundo segmento de suporte (13), sendo que cada segmento de trava (8, 9) e o respectivo segmento de suporte (12,13) são de tal maneira configurados que disponibilizam uma fixação axialmente encaixável e radialmente com travamento devido à forma entre o suporte de aleta diretriz (2) e a respectiva aleta diretriz (3), sendo que ao menos um elemento de segurança (14) está fixado ao suporte de aleta diretriz (2) e de tal maneira configurado que disponibiliza uma fixação axial de ao menos uma das aletas diretrizes (3).
