Abstract

resumo “lâmina de turbina” a presente invenção se refere a um sistema de mitigação de poeira para aerofólios (32) que inclui uma pluralidade de voltas de ponta contornadas (60, 62) que se curvam com respeito a pelo menos dois eixos geométricos (a, b). isto inibe áreas de recirculação comuns no interior de aerofólios e inibe, adicionalmente, o acúmulo de poeira na trajetória de fluxo de resfriamento do aerofólio.
