STATOR OF GAS TURBINE ENGINE COMPRESSOR Russian patent published in 2003 - IPC

FIELD: aircraft industry. SUBSTANCE: invention relates to design of compressors of gas turbine engines of ground and aircraft application. According to invention, stator of compressor of gas turbine engine including outer housing, working semiring and semiring of guide vane assemblies with flexible envelopes in between, is provided with solid inner housing with T-shaped ring radial ribs installed between flexible envelopes and working semirings. Elastic envelopes of outer housing are telescopically installed along working surfaces. Working surface of rib nearest to input of compressor is inclined in direction of compressor output at angle of 5-10^o to compressor axis. Invention provides sealing of air spaces between outer and inner housings and prevents thermal stresses and it increases reparability of compressor stator owing to provision of possibility of disassembling of housings. EFFECT: increased efficiency and improved reliability. 2 dwg
