Abstract (en)
[origin: EP1793093A2] The turbine distributor sector, comprising inner and outer (4) platforms with blades fixed between them, has one or more flanges (5, 6) fixed by one end (5a, 6a) to at least one of the platforms and made with recesses (10) to give them flexibility. The recesses are in the form of hollows in the ends of the flanges fixed to the platforms but do not pass through the flanges. One of the flanges (5) extends in a radial plane relative to the turbine sector's axis of revolution, while the other (6) is semicylindrical relative to the same axis.
