AXIAL COMPRESSOR Russian patent published in 2019 - IPC F04D27/02

Abstract RU 2694454 C1

FIELD: engines and pumps.

SUBSTANCE: invention relates to aircraft engine building and can be used in axial compressors. Proposed invention differs from known ones in that in case of bushing at M-th stage, where M<N, N is number of stages of axial compressor, there is an annular cavity and channels for removal of working body from it to vane backs, and inside each blade there is a channel for supply of working medium into annular cavity connected to flow part of last stage.

EFFECT: use of the proposed invention will make it possible to increase efficiency factor, degree of pressure increase and compressor stability margin.
