COMPRESSOR STATOR OF GAS TURBINE ENGINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; gas turbine engines of aircraft and ground applications. SUBSTANCE: according to invention, in stator of compressor of gas turbine engine including compressor housing and variable-incidence blades with outer trunnions, L-shaped ring rib is made on outer surface of housing. Cylindrical bushings are installed in cylindrical part of rib in which outer trunnions of blades are secured at l/h=2.5-5 where 1 is length of blade feather, h is height of ring L- shaped rib. EFFECT: improved reliability and efficiency of compressor owing to reduced wear of outer trunnions of blades. 3 dwg
