Abstract

“aerofólio” de acordo com algumas realizações, um aerofólio 30 compreende pelo menos uma parede que define uma borda anterior 32, uma borda traseira 34, um lado de pressão 38 que se estende entre a borda anterior e a borda traseira e um lado de sucção 36 que se estende entre a borda anterior e a borda traseira. o aerofólio é curvo em três dimensões e tem uma ou mais cavidades 39 definidas por uma superfície interior da pelo menos uma parede. uma pluralidade de orifícios de filme de resfriamento 70 que se estende entre a cavidade e pelo menos um sulco de resfriamento 50 localizado em pelo menos um dentre o lado de pressão e o lado de sucção, espaçado em relação à borda anterior. o pelo menos um sulco tem um piso 60 espaçado em relação a uma superfície externa 31 do aerofólio. a pluralidade de orifícios de filme de resfriamento se estende através do piso em um ângulo diferente de perpendicular.
