Abstract

Pá DE GUIA DE ENTRADA, MéTODO PARA PROJETAR UMA Pá DE GUIA DE ENTRADA, E, ABA PARA UMA Pá DE GUIA DE ENTRADA Um pá de guia de entrada proporciona um fluxo de ar suave aperfeiçoado e evita separação de fluxo sob altos ângulos de incidência. A pá de guia de entrada inclui um esteio tendo superfícies laterais opostas que são continuamente curvadas para proporcionar uma distribuição de velocidade controlada na bonda de fuga do esteio. A pá de guia de entrada adicionalmente inclui uma aba tendo uma borda de ataque alinhada por trás da borda de fuga do esteio. Geralmente, o esteio e a aba são construídos conjuntamente para que ar de baixo momento no intervalo entre o esteio e a aba seja ativado e arrastado na camada limite da aba. O fluxo de ar proveniente do intervalo permanecerá apenso à aba para aperfeiçoar o fluxo proveniente da aba.
