Abstract

The invention relates to a rotor disk (1) for an internal combustion engine, in particular a radial fan impeller or compressor disk. An uneven number of complete and solid blades (4, 5) are arranged at varying angular distances and in a varying sequence. This further reduces the generation of noise.
