Abstract

a invenção refere-se ao campo de pás de turbomáquina, e mais especificamente a uma blindagem de bordo de ataque (32) para uma pá de turbomáquina (16), se estendendo na direção de sua altura a partir de uma extremidade de fundo (40) até uma extremidade de topo (41), tendo uma face externa (50) se sobrepondo a um bordo de ataque (18) e uma face interna (51) destinada a ser presa a um corpo de pá (30), e uma aleta lateral de pressão (34), uma aleta lateral de sucção (36) e uma seção central (38) juntando a aleta lateral de pressão (34) e a aleta lateral de sucção (36). a seção central (38) tem uma espessura (e1) que é superior às da aleta lateral de pressão (34) e da aleta lateral de sucção (36) entre a face externa (50) e a face interna (51). a espessura (e1) da seção central (38) aumenta, com um gradiente estável ou que aumenta, sobre um primeiro segmento (s1) a partir de uma extremidade de fundo da blindagem de bordo de ataque (32), mas tem um gradiente que diminui para além de dito primeiro segmento (s1).
