Abstract
resumo patente de invenção: "conjunto de ventilador axial de pontas livres". a presente invenção refere-se a um conjunto de ventilador axial de pontas livres que inclui um ventilador que tem uma geometria da ponta da pá que minimiza o efeito adverso de uma abertura da ponta. a espessura máxima da pá exibe um aumento significativo adjacente à ponta da pá. em algumas construções, a espessura máxima na ponta da pá é pelo menos 100 por cento a mais do que a espessura máxima 0,10 r afastada da ponta da pá. em algumas construções, a espessura da borda posterior na ponta da pá é aproximadamente a mesma que a espessura da borda posterior 0,10 r afastada da ponta da pá. em algumas construções, o aumento na espessura da pá segue o quadrado da distância da posição onde o aumento começa.
