Abstract (en)
[origin: WO2011089355A1] The invention relates to an assembly consisting of a diffuser (1) and an airflow rectifier (2) at the outlet of a centrifugal compressor of a turbine engine, said diffuser being substantially in the shape of a radially positioned double annular disc, and said rectifier being a double toroidal part, arranged as an extension of the double disc of the diffuser and curved such as to divert the airflow in the downstream direction of the engine, characterised in that said rectifier is attached to said diffuser by a connection positioned immediately adjacent to the contact surface of the two parts and is removable using a standard tool, excluding any other supporting means.
