ULTRASONIC FAULT DETECTION SYSTEM ON AN AIRCRAFT ENGINE ROTATING ELEMENT

摘要

The invention relates to a system for the automatic detection of defects on at least one rotating element of an aircraft engine, comprising: embedded emission means (9) for scanning said rotary element (3) of the engine (5); ) by ultrasonic waves, ultrasonic receiving means (11) embedded to recover the ultrasonic waves reflected by said rotating element, and processing means (15) for forming an ultrasonic representation reflecting the ultrasonic waves reflected by said rotating element. and calculating differentials relating to an ultrasound component between different current subdivisions of said representation to detect variations of said ultrasonic component indicative of defects on said rotating member.
