Abstract

See full text

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