Abstract

Patente de Invenção: <B>"BOCAL DE TURBINA COM RESFRIAMENTO DE PELìCULA EM DECLIVE"<D>. Um catavento de bocal de turbina (18) inclui paredes laterais de pressão e sucção (26, 28) que se estendem entre as bordas frontal e traseira (34, 36). O catavento inclui um par de estrias integrais (38, 40) que definem três canais de resfriamento internos (42-46) entre as bordas frontal e traseira. As fileiras de orifícios de resfriamento por película (1-13) estendem-se através das paredes laterais, e três fileiras (8-10) no lado de pressão são inclinadas ao longo da envergadura do aerofólio a declives diferentes.
