Abstract

1/1 resumo “pá de turbomáquina, notadamente para disco com pás monobloco” a invenção se refere a uma pá de turbomáquina, que compreende uma lâmina que se estende axialmente entre um bordo de ataque e um bordo de fuga e radialmente entre um pé e um topo. o bordo de ataque da lâmina apresenta um ângulo de flecha que é positivo e continuamente crescente a partir do pé até uma primeira altura radial de lâmina (h1) situada entre 20 % e 40 % da altura radial total da lâmina medida a partir do pé na direção do topo, e continuamente decrescente a partir dessa primeira altura radial de lâmina até o topo.
