Abstract

Patente de Invenção: <B>"VENTILADOR DE FLUXO AXIAL, DE PESO LEVE, BAIXA SOLIDEZ, E ALTO RENDIMENTO"<D>. Um ventilador de fluxo axial de alto rendimento, baixa solidez, peso leve, (100, 200, 300) inclui um cubo (102, 202, 302), pás de ventilador (104, 204, 304) e um banda circular (106, 206, 306). O cubo (102, 202, 302) gira em torno de um eixo geométrico de rotação (110, 210, 310) quando torque é aplicado por um eixo (não mostrado) rotativamente acionado por uma fonte motriz (não mostrada). A banda circular (106, 206, 306) é concêntrica com o cubo (102, 202, 302) e é espaçada radialmente para o exterior do cubo. As pás (104, 204, 304) são distribuídas circunferencialmente em torno do cubo (102, 202, 302) e se estendem radialmente do cubo para a banda circular (106, 206, 306). As pás (104, 204, 304) são configuradas para produzir um fluxo de ar quando giradas em torno do eixo geométrico de rotação (110, 210, 310). Cada pá (104, 204, 304) tem uma distribuição de comprimento de corda que varia ao longo da extensão da pá, de tal maneira que o comprimento de corda tem um valor mínimo local em uma posição predeterminada entre as extremidades da pá.
