FIELD: mechanical engineering; turbines. SUBSTANCE: proposed gas turbine plant with gas generator comprises low-and high-pressure compressors. Ring slot fund behind first blade of low-pressure compressor communicates at inlet with periphery of compressor setting and at outlet, with atmosphere. Ring space found at outlet of low-pressure compressor communicates at inlet with periphery of passage channel between compressors, and at outlet, with atmosphere through housing blow-out system. Ratio of area of ring slot section to area of setting behind first working blade of low-pressure compressor is within 0.005 and 1. EFFECT: improved reliability and efficiency of gas turbine plant owing to two-stage cleaning of air delivered to high-pressure compressor. 3 dwg
