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.

L'invention porte sur un véhicule sous-marin qui se déplace dans différentes orientations et différentes directions, y compris le tangage, le lacet, le roulier, la levée, la poussée et le balancement. Le véhicule sous-marin comporte un corps supérieur et un corps inférieur, les deux corps étant séparés par deux gouvernails. Un gouvernail est positionné vers l'avant du véhicule sous-marin tandis que l'autre est positionné vers l'arrière. Chaque gouvernail forme la base d'un système de propulsion, de telle sorte que le véhicule sous-marin a au moins deux systèmes de propulsion commandés indépendamment. Chaque système de propulsion comporte en outre un élévateur s'étendant horizontalement à partir des côtés de chaque gouvernail et un générateur de poussée fixé à l'élévateur. L'élévateur et le générateur de poussée peuvent tanguer autour d'un axe s'étendant horizontalement à travers les côtés du gouvernail, et le gouvernail peut dévier autour d'un axe s'étendant verticalement à travers les parties supérieure et inférieure dudit gouvernail.
