Title: INTERFACE MEMBER FOR RECONDITIONING A CONTROL RING OF AN ENGINE COMPRESSOR, AND ASSOCIATED RECONDITIONING METHOD
Abstract:
An interface member (PI) equips a control ring (AC) of a high-pressure compressor of an engine. This control ring (AC) has at least one housing (LP') intended to partially house a guide shoe. This interface member (PI) comprises a central wall (PC1) to which two holding tabs (PM) are secured, delimiting a through-housing (LT) having dimensions substantially identical to the initial dimensions of the housing (LP'), and suitable for being inserted into the housing (LP'), after it has been machined to receive same following a deformation, until the holding tabs (PM) keep it stationary relative to the control ring (AC).
