ABSTRACT:
A method of manufacturing a turbine comprising a plurality of blades disposed between two end plates and defining flow passages between an inner ring and an outer ring. The turbine is formed by first and second parts, each part made as a single one-piece part out of thermostructural composite material. The first part forms both a first end plate and the blades, and the second part forms the second end plate that is applied against the blades of the first part. The first part and the second part are preferably assembled to each other solely by being clamped together via their central portions.
