The aircraft-carrier Charles de Gaulle is a very complex system. It will be commissioned after a period of almost 20 years of studies and building. In this enormous amount of work, hydrodynamics represent quite a small percentage. But a large part of the performances of the boat depends on its hydrodynamic qualities.
It can be understood that the feedback have to be organised after such a long period of time. The PaCdG sea-trials performed during the year 1999 included a significant part for hydrodynamics.
The emphasis has to be put on the exceptional quantity and quality of the measurements performed during these trials. Are concerned: propulsion tests, cavitation, pressure fluctuations, structure responses and manoeuvring. Investigations about some problem concerning bulge slamming and rudder vibrations are also reported.
