Abstract (en)

[origin: EP0761977A1] The turbine (10) consists of a number of blades (22) disposed between two flanges (24,30), the blades and the flanges being made out of a composite material of a carbon fibre in a matrix of carbon or ceramic. The first piece (20) is made as a single mono-bloc piece from a composite material forming the first flange (24) and the blades (22). It is first consolidated in a mould and then machined. The second piece forming the second flange (30) is machined from a composite material formed in a mould and consolidated. The two parts (20,30) are then assembled with the blades (22) in contact with the second flange (30) and clamped up centrally.
