CALCULATION METHOD OF ARRANGING POSITION IN FAN BLADE

摘要

The present invention relates to a blade of a sirocco fan or a cross flow fan and more particularly to a blade of a sirocco fan or a cross flow fan, To a method for calculating the above-mentioned value.;To this end, the _{x n = r · x (1} -x) logistic function [, where x _n: the factory-default values, r: constant, x: Initial value] an array position (x _1, x ₂ of the blade, using, x _3, ..., X _n ), calculating a base value (占 within the range of 占 by dividing each calculated initial base value by the highest value among the calculated initial base values And a step of adding or subtracting the calculated basic value at each position from the value (basic angle: [theta]) at which the blades are positioned at regular intervals to set the array position of the blades.
