초록

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...
