Abstract
Patente de Invenção: <B>"FURO DE RESFRIAMENTO ESTRIADO"<D>. Um aerofólio de turbina (14) inclui lados de pressão e sucção (22, 24) que se estendem longitudinalmente da raiz (26) a ponta (28) e de modo cordal entre as bordas dianteira e traseira (30,32). Um furo de descarga estriado (38) termina fora do aerofólio para descarregar o refrigerante daí.
