The improved dual-entry radial compressor rotor of the present invention has two sets of alternating full length and partial length blades on a symmetrical hub, with the partial length blades on one hub side terminating at the rotor high velocity exit coincident with the full length blades on the other hub side, to smooth the gas velocity profile in the tangential direction. Aerodynamically shaped sawtooth-profiled reliefs are provided in the hub radial portion between the blade tips to allow induced pressure differentials between the flow paths to smoot...


An improved high performance centrifugal compressor of the type having a rotor with a pair of opposing axially directed low velocity inlets and a common, radially directed high velocity outlet, the compressor rotor having an integral, axisymmetric hub with a central, full radius portion and two tapering flanking portions, the hub defining, in part, twin flow paths through the compressor, the improvement comprising: two sets of full length compressor blades mounted on the hub, the individual blades of each full length blade set extending along substantial...
