IMPELLER FOR MIXED FLOW COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide an impeller capable of suppressing or preventing a counter flow of fluid inside a diffuser and enhancing efficiency of a mixed flow compressor. SOLUTION: The impeller 10 for the mixed flow compressor has a plurality of blades 11 and a hub 12 arranged in root parts R of the plurality of blades 11, and a surface of the main body 12 where rear edge parts of the plurality of blades 11 are positioned is inclined to a rotational shaft in a plane including the rotational shaft. The rear edges TE of the plurality of blades 11 are formed so as to be positioned on a line approximately parallel with a rotational axis C of the hub 12. COPYRIGHT: (C)2005,JPO&NCIPI
