<P>PROBLEM TO BE SOLVED: To provide an impeller of a centrifugal compressor which has a splitter blade, and can achieve higher efficiency by improving a pressure ratio, and improvement of durability, by uniformizing the load distribution on the shroud side and the hub side of the splitter blade. <P>SOLUTION: The shroud side of a leading edge 7a of a splitter blade 7 is arranged more closely to a negative pressure surface Sb side of a full blade 5F from the circumferentially equally-spaced position of the full blades 5R, 5F, and further, the hub side of a trailing edge 7b of the splitter blade 7 is arranged more closely to the negative pressure surface Sb side of the full blade 5F from the circumferentially equally-spaced position of the full blade so that the blade tip leakage eddy W rides over the leading edge 7a of the splitter blade 7 with respect to the blade tip leakage eddy generated from the blade tip clearance between the fore end of the full blade 5F and the shroud to the leading edge 7a part of the splitter blade 7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
