Underwater vehicle with variable configuration

An underwater vehicle with variable configuration of a type comprising at least one hull to which thrusters are associated for moving and maneuvering in water the underwater vehicle, comprising:

• at least four elongated elements, provided for defining the hull and mutually articulated in correspondence with respective ends by means of joints, to form a first closed polygonal structure, arranged on a plane and centered with respect to two orthogonal symmetry axes;
• at least one thruster, associated with each of the elements of the hull and designed to provide a direct propulsive thrust with a given angle of inclination with respect to a longitudinal axis of the respective element in the plane identified by the first closed polygonal structure;
• and
• actuating leans, associated with the joints, provided fat varying and stabilizing a predetermined angle between two respective consecutive elements of the hull, so as to obtain, for the first closed polygonal structure, at least two characteristic configurations, one with an elongated shape and one with expanded shape, to which a first elongated conformation with a reduced cross-section of the hull corresponds, in which the elements of the hull are arranged almost parallel to each other, and a second substantially isotropic conformation, wherein the elements of the hull are mutually angled, intended for hovering of the underwater vehicle, respectively.
