Abstract

The invention relates to an assembly forming an outer shell sector (28) for a bladed ring sector (20) intended for a turbine or compressor stator of an aircraft turbine engine, comprising a plurality of elementary sectors (30) and vibration-damping blocks (34) disposed between the two elementary sectors associated therewith. According to the invention, the profile of each vibration-damping block (34) is substantially identical to that of the elementary sectors (30).
