Radial inner assembly for bladed ring sector of compressor stator or turbine of e.g. turbojet engine of aircraft, has anti-rotation edge whose length is greater than maximum spacing distance between projections of casing head

摘要

The assembly (33) has a casing for adjusting radial position of an inner shell sector (24). An anti-rotation plate prohibits rotation of the casing with respect to the inner shell sector. The plate has a housing whose shape is complementary to that of a casing head, where the housing receives the head. An anti-rotation edge is in contact with the inner shell sector and/or abradable coating support. The edge has length greater than maximum spacing distance between projections of the casing head. An independent claim is also included for a bladed ring sector of a compressor stator or a turbine of a turbo machine of an aircraft.
