METHOD OF INSPECTING IMPACTS OBSERVED IN FAN CASINGS

摘要

The present invention relates to a method for inspecting impacts (Ii) present on an internal face (104) of a fan casing (100), said method being characterized in that it comprises the following steps consisting in: - spotting (201) a first impact (I1) present on the internal face (104) of the fan casing (100); - delimiting (202) an inspection area (106) containing said first impact (I1); - spotting (203) the various impacts (Ii) present in the delimited inspection area (106), said various spotted impacts forming a set of impacts to be considered; - measuring (204), for each impact (Ii) that is to be considered, the depth of length of said impact (Ii); - for each impact (Ii) to be considered, determining (205) a harmfulness value, using at least one chart (300; 400) relating the depth and length of each impact to be considered to a level of harmfulness; - determining (206), for the inspection area (106) containing the first impact (I1), a total harmfulness value by adding together the harmfulness level determined for each impact (Ii) to be considered.
