- 摘要：
- PROBLEM TO BE SOLVED: To accelerate a high pressure ratio of a centrifugal compressor 29 upon setting large a margin between a characteristic value of a full blade 41 and a lower limit characteristic value of a reference.SOLUTION: An outer edge part 39o of a compressor disc 39 is located radially outward of a rear edge 41b of a full blade 41, a rear edge 43b of each splitter blade 43 is located at the same radial position as a position of the outer edge part 39o of the compressor disc 39, a radial length L1 of the rear edge 43b of each splitter blade 43 is set to be equal to or smaller than 1.30 times as large as a radial length L2 of the rear edge 41b of the full blade 41, a backward angle θ1 of the full blade 41 is set to 20 to 50 degrees, and a backward angle θ2 of each splitter blade 43 is set to 30 to 60 degrees.SELECTED DRAWING: Figure 1
