EXTERNAL SECTOR SECTOR FOR AIRCRAFT TURBOCHARGE STATOR RING SHOCK RING INCLUDING WEDGE VIBRATION DAMPING

摘要

1. The scapular ring sector (20), designed to be mounted on the compressor stator of the aircraft turbomachine, comprising an assembly forming the outer shell sector (28), the inner shell sector (24) and a plurality of blades (18) inserted tangentially apart from each other, inserted between the assembly forming the outer shell sector and the inner shell sector, said blades being attached to each assembly forming the outer shell sector and the inner shell sector, said assembly forming the outside sector (28) bottom shell, containing, firstly, a plurality of elementary sectors (30) at a distance from each other along the tangential direction (22) of the assembly, and secondly, vibration-damping wedges (34), each of which is inserted between two elementary sectors associated with it, placed directly sequentially along the tangential direction, characterized in that the profile of each vibration damping wedge (34) is approximately the same as the profile of elementary sectors (30) .2. A sector according to claim 1, characterized in that said wedge is brought into contact with two parallel planar friction surfaces (38) facing each other along said tangential direction (22) and provided respectively on said two elementary sectors (30) associated with said wedge, and the fact that said wedge (34) has two complementary flat friction surfaces (40) parallel to each other and interacting with two corresponding friction surfaces of elementary sectors. 3.
