ELASTOHYDRODYNAMICS OF TOWED SLENDER BODIES: THE EFFECT OF NOSE AND TAIL SHAPES ON STABILITY

A general theory is presented to account for the dynamics and stability of a slender flexible body with a rounded nose section and a truncated rounded tail section, towed underwater. Particular attention is focused on the hydrodynamic forces acting on the two extremities of the body, which are determined by means of ideal flow theory, rather than by slender body theory. To this end, general expressions were obtained for the forces and moments acting on an ellipsoid undergoing planer motions. Sufficient results are presented to illustrate (1) the dynamical behavior of the body with increasing towing speed, and (2) the effect of some parameters, such as the shape of the ends, on stability. It was found that stability is mainly controlled by the shape of the tail section of the body.
