Definitions

  • the invention provides an impeller and a stator for fluid machines, more particularly fans and compressors, which for reducing flow noise and for improving the stability of the characteristic curve between the flow input and output cross-section are formed by a solid material matrix with a plurality of flow channels where a deflection of the flow and the pressure increase connected therewith occur.
  • All struts e.g. for mounting the machine, are advantageously made either of a structured material are they are integrated into it for minimizing the size of the separation swirls.
  • FIG. 7 depicts different cellular structures for an impeller for a radial fan (radial section);
