BLADED STATOR HAVING FIXED BLADES MADE OF THERMOSTRUCTURAL COMPOSITE MATERIAL, E.G. FOR A TURBINE, AND MANUFACTURING PROCESS THEREFOR

摘要

The stator blades (10) are made of a thermostructural composite material and have asymmetric inner and outer roots (14, 16) such that at least one of the roots of an a blade presses against the outer side (12b) or inner side (12b) of a neighboring blade. Also, each root (14, 16) of each blade presses against the adjacent ring by a part only of its external surface, thereby allowing some flexing of the root under the effect of differential expansion between the blade and the ring.
