Abstract

Patente de Invenção: <B>"LINHA DE FLUXO ESTRIADA PARA COMPRESSOR"<D>. Uma linha ou via de fluxo de compressor (20) inclui aerofólios (16), espaçados pela circunferência apresentando bordas de condução e de arraste (28, 30) e extremidades externa e interna (32, 34), espaçadas radialmente. Uma parede externa (36) une as extremidades externas do aerofólio e uma parede interna (38) une as extremidades internas. Uma das paredes inclui uma estria (40), adjacente à bordas de condução para um aumento localizado da área de fluxo naquele local.
