| Abstract: | In this paper we study transient processes in one-dimensional deformable cables when there is a nonsteady change in length during towing in a stream of liquid or gas. A new hyperbolic-parabolic model is constructed that takes account of the longitudinal waves in the cable and nonlinear effects caused by the change in the length of the cable according to a prescribed law of control of its length. As an illustration we give an analysis of the evolutionary characteristics of a radial winch and the relative velocity of streamline flow around it for two tachograms of a winch simulating realistic working conditions in the operation of towed oceanographic systems.
