Abstract
A method for performing diagnostics of a structure subject to loads, in particular an aircraft structure, is implemented by an arrangement of sensors located at relevant points of the structure and corresponding neural networks. The method includes training the neural network in order to establish an associative relationship between the state of the structure in a subset of relevant points and the state of the structure in at least one residual relevant point. The state of the structure is detected in a plurality of relevant points under operating conditions. The state of the structure is estimated in at least one residual relevant point by the associated neural network on the basis of the pre-established associated relationship. The state of the estimated structure is compared with the detected state at the residual relevant point, such that an intact state of the structure is determined if the expected and detected values of the state parameter match, or a defective state of the structure is determined if these values differ.
