Abstract
1523422 Rotor blade fixing SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 24 March 1977 [25 March 1976] 12381/77 Heading FIT Each blade 1 of a fan or compressor is locked in an axially extending dovetail rotor slot 3 by a radially extending U-shaped member 6 engaging mating recesses 7, 8 in the blade root 2 and rotor 4 respectively. Member 6 is held radially by flexible retainer ring 14 itself held by projection 13 on fairing 10. Modified U-shaped members and retainers are described.
