A design concept will be produced for controlling the depth of fatline-towed arrays independent of boat speed and tow scope. The system will utilize existing TB-16 modules, and only add to or replace some array components. Depth excursions will be maximized through a combination of lift, weight reduction, and buoyancy addition. The updated system will utilize existing SSN array elements for flushing and retrieval, thru-hull seals, and deck storage hardware. The delivered design package will include concept drawings; component hardware and software specifications, and overall system performance requirements. An optional task is included to generate performance predictions using advanced flow and acoustic computational methods. Array forces, trajectories, vibrations, acoustic sources, and fatigue life will be quantified, and used to insure the concept design meets expectations prior to starting Phase II work.
