Description This thesis is primarily intended for aerospace, civil, or mechanical engineering students with an interest in structural dynamics.
Flight Vibration Testing is an emerging trend in research for flutter prediction and aircraft dynamics characterisation. This approach offers the advantage of incorporating the dynamic survey with the classic flight testing. This can be a fundamental advantage in the time-to-market of new designs, since both are requirements in the design and certification process of air and space vehicles. Recently, the Loewner Framework [1] was extended to output-only and to multi-input multi-output systems. The goal of this thesis would be to efficiently implement an output-only identification considering the frequency response functions with respect to all channels. This work would be carried out on numerical and experimental datasets (already available) of aeronautical, e.g. flexible wings, and civil, e.g. bridges, structures.
