Abstract

PURPOSE: To ensure the reduction of vane pitch noise, by varying either one of blade attachment interval, attachment angle or the blade shape at least at one place, whereby formation of sine curve which maximumizes the vane pitch noise can be prevented.
CONSTITUTION: While the pitch and shape of the blades 2 are all equal to one another as depicted in the sketch, as to an attachment angle θ of the blades 2, only an attachment angle θ2 is different from others. In this mechanism, the cycles become like varied waves and monotoneously abnormal noise is not felt. And, although pitches and attachment angles of the blades are all equal, as for shape of the blades 2, even by making shape of only a blade 22 different from other blades, the cycles follow not a sine curve but a varied wave noise and the monotoneously abnormal noise is not heard, and therefore, decrease in the vane pitch noise can be ensured.
