WEAR INDICATOR FOR A TURBOMACHINE, TURBOMACHINE EQUIPPED WITH SUCH A WEAR INDICATOR, AND METHOD FOR MEASURING A CLEARANCE BETWEEN THE OUTER PERIPHERY OF A BLADES WHEEL AND AN ABRADABLE LINER IN SUCH A TURBOMACHINE

摘要

The invention relates to a wear indicator (1a, 1b) for an aircraft turbine engine (18), characterized in that it comprises a body connected to a finger (13), said body being screwed into a first element ( 22) of a turbine engine (18), and said finger (13) being configured to wear by friction with a second element (23) of the turbine engine (18) which is movable relative to said first element (22). The invention also relates to an aircraft or test turbomachine (18), comprising: - a stator casing (28), - at least one abradable annular coating (32), and - at least one bladed wheel (26a, 26b), characterized in that it comprises at least said wear indicator (1a, 1b). The invention further relates to a method for measuring a clearance between an outer periphery (35) of a bladed wheel (26a, 26b) and an abradable coating (32) in said turbomachine (18).
