ABSTRACT:
This invention relates to a method to dertermine the shape of a fan blade of a sirocco fan which can improve fan efficiency and reduce the noise from flow, comprising the steps of determinating a camber line and, upper surface and lower surface of the blade by equations which define mean line and thickness distribution of NACA wing sections, respectively and determinating maximum ordinate of the camber line by following equation;
