METHOD AND SYSTEM FOR EVALUATING A STRUCTURAL INTEGRITY OF AN AERIAL VEHICLE

摘要: A method of evaluating a structural integrity an aerial vehicle comprising one or more engines comprises selectively driving said engine/s according to pattern unsuitable put maintain the in flight, recording vibrational response at least part selective engine/s, determining plurality modal parameters response, particular eigenfrequency and/or damping factor corresponding eigenfrequency, and classifying based on deviation from baseline for vehicle.
