Thrust-vectoring on Autonomous Underwater Vehicles is an appealing directional-control solution because it improves turning radius capabilities. Unfortunately, thrust-vectoring requires the entire propulsion system be articulated in two degrees of freedom. Consequently, substantial internal volume must be utilized for this system, reducing payload and battery capacity. To combat this problem, an alternative thrust-vectoring system is desired for an existing vehicle. A number of alternative design strategies and concepts are explored herein. One design concept is then chosen and feasibility calculations are performed. Analysis of hydrodynamic loading, actuators, bearings, and structural components is conducted. The design is then reviewed and improvements are suggested.
