<p>A turbocharger (5) comprising a housing (10) including a compressor shroud (14) and a turbine shroud (12). The turbocharger (5) further comprises compressor wheel (18) and a turbine wheel (16). The compressor wheel (18) includes a compressor hub (44) and a plurality of compressor blades (45 , 46) extending radially from the compressor hub (44). Each compressor blade (45, 46) includes a leading edge (50 , 51), a trailing edge (52 ,53,) and a compressor shroud contour edge (54, 55) extending therebetween. The turbine wheel (16) includes a turbine hub (24) and a plurality of turbine blades (26) extending radially from the turbine hub (24). Each turbine blade (26) including a leading edge (30), a trailing edge (32), and a turbine shroud contour edge (34) extending therebetween. At least one of the compressor and turbine blades includes an edge relief (40 , 60, 61) formed along at least a portion of the corresponding compressor or turbine shroud contour edge.</p> |
