STAGE OF VARIABLE-PITCH BLADES FOR A TURBINE ENGINE, TURBINE ENGINE AND ASSOCIATED INSTALLATION METHOD

摘要

The invention relates to a stage of variable-pitch blades (110) for a turbine engine, each blade including an impeller (114) which comprises: a first radially inner frustoconical surface (150) in which the cone angle is flared radially inwards and which is configured to engage with an inner frustoconical surface (152) of a first substantially frustoconical bushing (140), and a second radially outer frustoconical surface (154) in which the cone angle is radially flared outwards and which is configured to engage with an inner frustoconical surface (156) of a second substantially frustoconical bushing (142).
