Abstract

Patente de Invenção:<B>"ESTRUTURA PARA UMA PALHETA DE ESTATOR DE MOTOR A JATO OU TURBINA A GáS"<D>. Um conjunto de estrutura para palhetas de estator incluindo um anel estrutural externo (34), um anel estrutural interno (36), um conjunto de palhetas individuais (22) cada uma conectando o anel estrutural externo(34) e o anel estrutural interno (36), formando plataformas interna e externa com as palhetas (22) vizinhas definindo um conjunto de trajetórias de fluxo, um conjunto de membros de vedação (30, 32, 58, 70) conformado a um conjunto de folgas (60) entre o conjunto de palhetas (22) disposto para vedar a folga (60). Um método para a aplicação de um membro de vedação (30, 32,58, 70) contra as folgas (60) entre uma plataforma formada como resultado do acoplamento entre as palhetas (22) incluindo a fixação de um conjunto de palhetas de estator (22) em uma estrutura interna e a uma estrutura externa, e a vedação de um conjunto de membros de fixação (30, 32, 58, 70) sobre a superfície da parte traseira de uma estrutura de palheta de estator. A natureza discreta de uma palheta individual vedada pelos membros de vedação (30, 32, 58, 70) faz com que o conjunto de estrutura para palhetas de estator a adicione um efeito de amortecimento o qual aumenta a vida sem fadiga da palheta (22), e permite o emprego de material com menor resistência, mais leve e mais barato.
