Conceptual design of a thrust-vectoring tailcone for underwater robotics
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 …
