AXIAL-FLOW COMPRESSOR FOR TURBOMACHINE Russian patent published in 2006 - IPC F04D29/60 

FIELD: compressors for gas-turbine engines and turbomachines of ground application.

SUBSTANCE: proposed axial-flow compressor has housing with blade guide apparatus arranged inside it; at least one blade guide apparatus is swivel in construction. Locked on roots of guide blades are pivoted levers articulated with synchronizing rings; mounted on housing in diametrically opposite position are two drive shafts with parallel axes which are connected with power mechanism of blade guide apparatus drive by means of levers. Axes of drive shaft cross compressor axis. Swivel guide apparatus is provided with unit for control of variable-incidence blade position; this unit includes electric sensor connected with power mechanism and turbomachine automatic control system through transfer members and mounted on compressor housing. Electric sensor rotor axis is parallel to shaft axes.

EFFECT: enhanced operational reliability and efficiency due to enhanced accuracy of setting blade angle at all modes of operation.
