COMPRESSOR BLADE MAKING METHOD Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to methods of manufacture of compressor blades for aircraft gas-turbine engines and power plants, and working blades and guide vanes of fans and turbines. According to proposed method, plates are cut out of rolled metal sheet and placed in press tool following profile and size of blade. Plates are placed one onto the other without clearances and diffusion welding in vacuum or neutral atmosphere is carried out at temperature within 800 and 900^oC at pressure of 0.5-10 MPa. EFFECT: possibility of making compressor blades of preset profile and size with subsequent connection to each other. 3 cl, 1 tbl, 1 dwg
