Abstract
A method and a system for detecting an impact on an impeller wheel of an aircraft engine. A device acquires a revolutions per minute of the engine and a series of deflection signals representative of the deflections on the blades of the impeller wheel at the revolutions per minute. A device constructs signals for detecting impact on the impeller wheel by correlating each of the deflection signals with a predetermined signature of a shock on a blade at the revolutions per minute.
