Abstract

Sector (34) of a sealing ring (33) for a turbine of an aircraft turbomachine, the sector (34) extending circumferentially around an axis (X) and comprising a body (35) carrying a block of an abradable material (36), the body (35) being axially delimited by an upstream end (37) and by a downstream end (39), characterized in that the body (35) comprises a blind cavity (41) which is axially delimited by a bottom (42) upstream and an opening (43) which opens at the downstream end (39) of the body (35), the cavity (41) having a radial dimension (Dc) with respect to the axis (X) which increases continuously along the axis (X) from the bottom (42) of the cavity (41) to the opening (43) of the cavity (41).
