GAS-TURBINE ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed gas-turbine engine contains compressor, combustion chamber and turbine and intermediate housing with fitted-on outer housing of engine and housing of turbocompressor. outer housing of engine and turbocompressor housing are interconnected by posts over combustion chamber. Radial-thrust ball bearing is installed at compressor outlet. Intake guide-vane assembly is installed on intermediate housing. Outer ring of guide-vane assembly encloses working ring over first blade of compressor. fastening of outer and working rings is made for relative axial displacement along axially-spaced cylindrical surfaces between which ring closed space is formed communicating through multiple channels with compressor setting. EFFECT: increased efficiency and range of stable operation of compressor of gas-turbine engine owing to increased flexural rigidity of turbocompressor housing. 2 dwg
