Abstract:

Expressions of the sway and yaw damping coefficients are obtained for submerged slender bodies of revolution moving at a constant forward speed near a free surface, derived from the Lagally theorem for unsteady flow as extended by Cummins. The singularity distributions which generate the flow consist of a basic doublet distribution identical with that for a deeply submerged body and a higher order distribution to account for the effect of the free surface. Numerical values were obtained for a spheroid and the results were compared with the strip theory as well as the case of zero forward speed.
