COMPRESSOR Russian patent published in 2005 - IPC

FIELD: mechanical engineering; compressors.

SUBSTANCE: invention relates to single-stage and multistage axial and combination axial-centrifugal and axial-diagonal compressors of gas-turbine plants. Invention is aimed at enlarging range of gas-dynamic stability of compressor at preservation and increasing of level of its efficiency. Result is obtained owing to placing cylindrical or conical tubular vortex channels over blades of impellers, said channels overlap front part of blades of impellers, periphery of passage part before blades of impellers. Channels are closed at ends.

EFFECT: enlarged range of gas-dynamic stability of compressor.
