Skin-friction drag is a major source of energy dissipation in marine vehicles. In addition, self-induced noise generated by turbulent boundary layer can strongly limit the operation of on-board sensors. Therefore, designing surfaces with friction dra

Publikováno v: cnr.insean/2013-PR-001, pp.1–40, 2013

This report relates to the CNR-INSEAN model tests in open-water and close-to-free surface conditions. All the experiments have been performed to measure global loads (forces and moments) acting on the model and local moments (torque) on the rudders.

The even more large diffusion of self-pitching propellers leads to a more accurate analysis of their behaviour in running conditions, to avoid the onset of system instabilities under small deviations around the equilibrium working points. Unfortunate
