Abstract RU 2334901 C1

FIELD: engines and pumps.

SUBSTANCE: invention relates to compressor production and can be used in single- and multi-stage centrifugal compressors of gas turbine engines to increase their efficiency by reducing, at a time, edge losses and those related with the flow turn. The said stage incorporates an impeller, vaneless and vane diffuser, directing vanes, all arranged streamwise. Note that every vane of the vane diffuser is made integral with directing vane so that the latter represents a continuation of the vane diffuser vane with the set of the combined vanes profile central lines lying in one plane.

EFFECT: higher efficiency of the compressor.
