ラジアルタービン及び過給機
Document Type and Number:
Japanese Patent JP5772207
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress an increase in pressure loss in a turbine impeller 35 after sufficiently securing durability of a radial turbine 31.SOLUTION: Blade thickness at a leading edge 39L of each turbine moving blade 39 is gradually increased from a mean part 39Lm side to a hub part 39Lh side. A ratio of blade thickness of the hub part 39Lh to blade thickness of a tip part 39Lt at the leading edge 39L of each turbine moving blade 39 is set to be 3.0-5.0. A cross-sectional shape of each turbine moving blade 39 along a flow direction of exhaust gas at the leading edge 39L is formed into a semi-circular shape.
