DYNAMICAL STABILITY OF A TOWED THIN FLEXIBLE CYLINDER,

Abstract

The stability and dynamics of a slender cylinder towed in a viscous stream are examined. The cylinder is clamped at one end and free at the other. Stability conditions and modal shapes are found based on solutions to linearized equations resulting from small deflection assumptions. Particular attention is focused on the conditions of stability when the length/diameter ratio becomes large. It is found that the stability of a slender cylinder is virtually controlled by the tail portion of the cylinder which is about 25 diameters from the free end. Some experimental observations conducted in a towing tank are in general agreement with theory. (Author)
