Abstract

a invenção se refere ao campo de pás de turbomáquinas, e mais especificamente a uma blindagem de bordo de ataque (32) para uma pá de turbomáquina (16), que compreende uma aleta do lado de pressão (34) e aleta do lado de sucção (36), cada uma se estendendo na altura e direção do comprimento e conectadas juntas ao longo de suas alturas, a aleta do lado de pressão (34) tendo um comprimento maior que a aleta do lado de sucção (36) sobre um primeiro segmento (si) da blindagem de bordo de ataque (32), e um comprimento igual ou menor do que a aleta do lado de sucção (36) sobre um segundo segmento (s2) da blindagem de bordo de ataque (32).
