The article deals with a description of basic results of research of radial compressor stages with 2D e.g. prismatic rotor blades. The experimental facility and the measurement and evaluation process are described briefly in the first part. The second part of this contribution is the numerical simulation and evaluation of the influence of the technological holes in the 2D rotor blades to compressor stage characteristics. The influence of the labyrinth seals clearance on the working characteristics can be found in the last part. The comparison of measured and computed values is presented and discussed.
