<p>A centrifugal compressor impeller has a first set of splitter blades (40) positioned in the flow channels between the full length blades (30,32) such that about 1/3 of the channel flow is directed between each first splitter blade and the adjacent full length blade having its suction side facing the first splitter blade. Each blade of a second, shorter set of splitter blades (50), is positioned between the first splitter blade (40) and the adjacent full length blade (32) having its pressure side facing the first splitter blade to divide about in half the other 2/3 of the channel flow.</p> |
