The four papers which comprise this report are all concerned in some way with the comparison between the mathematical model of the airplane and its actual behaviour on the ground or in flight. New structural testing methods are presented, which make it possible to provide the designer with accurate results for comparison with the finite element description of the structure, and with corrections to this model. A summary is given of the work done on the MRCA, from the design stage to the flight flutter test, to understand and analyse the aeroelastic phenomena. New reduction techniques which greatly improve the accuracy of flight flutter test results are presented. The final paper show how the problem of interactions between the aircraft structure and the command and stability augmentation system has been solved on the MRCA. Author
