Abstract (en)

The stage has a set of fixed blades (2) connecting an inner collar (4) to an outer collar, where the exterior collar is realized by a composite material. The fixed blades have attachment platforms (7) with flat surfaces that co-operate with multiple juxtaposed flat facets. The flat facets are located on the inner face of the outer collar in order to ensure a flat type contact fixation between the fixed blades and the outer collar. The platforms are positioned side by side so as to present a continuous smooth surface to the airflow. An independent claim is also included for a method for manufacturing a rectifier stage for a turbine engine.
