Abstract (en)
[origin: EP1500791A1] The blade's outer pivot (11), designed to rotate inside a bore (22) in the turbine stator casing (21), is located inside a sleeve (30) of greater length than the bore and having a hooked end (31) that projects beyond the bore. The sleeve can be made from a low friction material inside a metal jacket with a hooked outer end and a locating collar (32). The hooked end makes for convenient sleeve extraction without dismantling the blade.
