GAS-TURBINE PLANT Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed gas-turbine plant has two-shaft single-circuit engine with low-pressure and high- pressure compression and power turbine with exhaust device. First working blade of low-pressure compressor is made with ratio of height of blade at compressor inlet to width in blade root section along engine axis equal to 0.7 - 1.3. Ratio of area of compressor blading at inlet to first working blade of low-pressure to area of compressor blading at outlet from guide vane of first stage of low-pressure compressor is equal to 1.3-2.0. EFFECT: improved economy, efficiency and reliability of plant owing to increase of compression ratio of low- pressure compressor and strength of blades of first stage. 2 dwg
