Abstract

trata-se de uma pá de turbina de turbomáquina (1) que compreende uma face de sucção (11), uma face de pressão (12), um bordo de ataque (13) e um bordo de fuga (14) assim como um rebaixo (2) na ponta dos mesmos, sendo que a dita ponta rebaixada (2) que compreende pelo menos uma nervura interna (3), distinguida pelo fato de que a dita nervura (3) se estende de um ponto de fixação (31) do aro (2a) do dito rebaixo (2) sobre o lado de face de sucção (11) até um ponto de fixação (32) do aro (2a) do dito rebaixo (2) sobre o lado de face de pressão (12) e compreende uma porção para absorver a carga de fluxos de vazamento (16) que se estende da face de sucção (11) e uma porção formadora de defletor que estende a porção absorvente de carga com uma inflexão e guia os fluxos de vazamento (16) em direção à face de pressão (12).
