Document Type and Number:
WIPO Patent Application WO/2016/208632
Kind Code:
A1
Abstract:
In this vaned wheel, all blades (3p...) are divided into at least four blade groups (G1...) each including a fixed number of blades (3p...), said fixed number being at least three. In this way, the blade (3p) in each blade group (G1...) that is located in the rearmost position in the direction of rotation (Fr) is selected as a main blade (3pm), and the remaining blades (3p...) in the group are selected as auxiliary blades (3pa...). The length of each auxiliary blade (3pa...) is set to be shorter than the length of the main blade (3pm), and a corresponding inner end portion (3pi...) of each blade (3p...) is positioned to the front, in the direction of rotation (Fr), of a normal line (Lv...) passing through an outer end portion (3po...) of the relevant blade (3p...), and an extension line (Lge...) of a chord line (Lg...) joining the outer end portion (3po...) of each blade (3p...) to the inner end portion (3pi...) thereof is caused to intersect the main blade (3pm) that is adjacent to the front, in the direction of rotation (Fr).
