FIELD: aviation material and ground equipment. SUBSTANCE: compressor of gar-turbine engine has stator with guide-vane assembly and inner housing. Ring slot is made in inner housing between vanes of guide-vane assembly and working blade. Ring slot is tilted in direction of low. Angle of slot opening is α = 2-20^°, at H = 1,2-2,2h where is h is width of slot from side of blades along axis of compressor, and H is distance between leading edge of working blade and trailing edge of vane of guide-vane assembly. EFFECT: improved reliability and preserved gas-dynamic stability owing to minimization of hydraulic losses when taking off air from compressor blading. 1 dwg
