Since its first use in 1988, the Grand Tunnel Hydrodynanique (G.T.H.) has proved that it is a rather unique experimental facility to conduct innovative experiments to improve the design of ship propulsors specially with regard to cavitation and hydroacoustic performances. This paper presents a review of the experimental capabilities of the tunnel and of the measuring techniques used, with emphasis on the significant advance in propulsor noise investigations obtained from the model tests performed in this facility and compared with full scale data. The results obtained point out that not only the noise of cavitating propulsor can be predicted but also the noise of non cavitating propulsor which is known not to be an easy task. One main result is that, for surface . ship, the broad band noise of a propulsor operating without cavitation is not the predominant contribution to ship radiated noise.
