GAS-TURBINE ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; gas-turbine engines of aircraft and ground application. SUBSTANCE: proposed gas-turbine engine contains compressor with disks installed on shaft through splines. Inner surface of disk hub between splines is made with radius R=1.02 - 1.1r, and number of splines on disk hub is n1= 0.2-0.6n2 where r is outer diameter of compressor shaft splines, R is radius of inner surface of compressor disk hub, n1 is number of splines on compressor disk hub, n2 is number of splines on compressor shaft. EFFECT: improved reliability of engine owing to increased strength of compressor disk. 3 dwg
