Abstract (en)
[origin: WO8203657A1] A floating expansion control ring (20) having a plurality of radially extending positioning lugs (18) is free to move eccentric to the axis of an enclosing engine (24) and within the confines of a spacer ring (14) rigidly mounted within said engine (24). This eccentric movement in a turbine engine permits slight eccentricities of a turbine rotor (11) in a turbine engine. This eccentric movement eliminates the need for abradable shrouds and abradable turbine blades.
