Abstract

Patente de Invenção: "PALHETA DE TURBINA PARA MOTOR A TURBINA A GáS E MéTODO PARA RESFRIAMENTO DA MESMA". A invenção refere-se a uma palheta de turbina (30) inclui uma plataforma (40) e um aerofólio (42) se estendendo radialmente da plataforma (40). Um circuito de resfriamento interno (54) é formado no aerofólio (42) para circular um refrigerante através dele para esfriar o aerofólio (42). Pelo menos uma passagem de abastecimento (110) é fornecida para direcionar um pouco do refrigerante que passou pelo menos parcialmente através do circuito de resfriamento interno (54) para cima da plataforma (40) para esfriar a plataforma (40).
