Propulsion System for an Autonomous Underwater Vehicle

摘要

An underwater vehicle is provided to move in various orientations and directions, including pitch, yaw, roll, heave, surge and sway. The underwater vehicle comprises an upper body and a lower body, wherein both bodies are separated by two rudders. One rudder is positioned towards the fore of the underwater vehicle, while the other is positioned towards the aft. Each rudder forms the basis of a propulsion system, such that the underwater vehicle has at least two independently controlled propulsion systems. Each propulsion system further comprises an elevator extending horizontally from the sides of each rudder and a thrust generator attached to the elevator. The elevator and thrust generator are able to pitch about an axis extending horizontally through the sides of the rudder, and the rudder is able to yaw about an axis extending vertically through the top and bottom of said rudder.
