Abstract (en)
[origin: EP1811131A2] The synchronizing ring for a turbine compressor comprises coaxial internal (20) and external (52) shells, between which radial blades (24) are mounted. A collar (56) on the external shell allows the ring to be attached to a frame. The leading (26) or trailing (28) edges of the blades are attached to areas on the external shell which are less rigid than those connected to the collar.
