Abstract

resumo “palheta fixa de distribuição de fluxo em uma turbomáquina, turbomáquina e processo de fabricação de uma palheta fixa de distribuição de fluxo” a presente invenção trata de uma palheta (10) fixa de distribuição de flux em uma turbomáquina, que compreende uma plataforma anular interna (12) e uma pluralidade de palhetas fixas (11) montadas sobre ela, sendo que a plataforma interna compreende uma placa de suporte (121) que forma a base das referidas palhetas, uma divisória anular radial (120) que se estende a partir da placa de suporte para um eixo da palhea, e uma coroa interna (122) aplicada sobre a divisória anular radial, e que apresenta uma superfície interna sobre a qual está disposto um material abrasivo (123), a qual palheta se caracteriza pelo fato de que a coroa interna comporta pelo menos um corte (1223) que delimita uma lingueta (1226), e a lingueta está dobrada para se apoiar sobre a divisória anular radial (120). a presente invenção trata igualmente de um processo de fabricação de tal palheta e de uma turbomáquina que integra tal palheta.
