GAS-TURBINE ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed gas- turbine engine contains turbine disk on which disk cover deflector consisting of hub and plate is mounted. Deflector plate has radial outer wall and inner wall inclined relative to disk. Inner wall is made with tilting from hub of deflector to its periphery. Ratio of maximum thickness of deflector to its minimum thickness of periphery of deflector is 1.2-3. EFFECT: improved reliability of gas-turbine engine owing to prevention of parasitic leaks of cooling air between end faces of disk and deflector at place of fastening and prevention of overheating of blade. 3 dwg
