Abstract

1353114 Turbomachine blades GENERAL ELECTRIC CO 9 Feb 1972 [23 April 1971] 5936/72 Heading FIT To reduce vibration, adjacent turbine or compressor rotor blades are interconnected by sleeves 23 freely engaging over lugs 22 projecting from bosses 21 on the blade flanks. The ends of each sleeve 23 are cut back at 25 and the lugs 22 rounded at 24 to permit the blades to twist without developing transverse loads on the lugs and sleeves. The latter have the cross-section shown in Fig.4.
