TURBOMACHINE COMPRISING A CASING WEAR INDICATOR

摘要

The present invention relates to a turbine engine comprising a casing (7) which has an inner wall (3i) forming a wall of an air duct (3) and at least one opening (7r) passing through the casing, leading into said duct (3) and forming a passage for an endoscope, the opening (7r) being closed during operation of the turbine engine by a stopper (8) which has an end-surface portion (8s) in the extension of the inner wall (3i), characterised in that an indicator of wear to the inner wall of the casing is associated with the stopper (8) or with the inner wall (3i) of the casing, in the proximity of the stopper (8). The means of the invention allows simple inspection, without a measurement apparatus being used.
