Various examples of a high-speed omnidirectional fully-actuated underwater propulsion mechanism are described. In one example, a propulsion system includes two decoupled counter-rotating rotors centered on a main axis, with each rotor comprising a plurality of pivotable blades projecting radially from the main axis, a servo-swashplate actuation mechanism comprising a plurality of servos and a linkage assembly connected from the servos to the pivotable blades, a blade-axis re-enforcing flap adapter comprising a plurality of stationary flaps, with the blade-axis re-enforcing flap adapter being positioned in a region between the two decoupled counter-rotating rotors centered on the main axis, and a controller. The controller can be configured to calculate control parameters, compensate a first control parameter among the control parameters to reduce cross-coupling of an unwanted force generated by drag forces on the two decoupled counter-rotating rotors, and generate a control signal for each of the servos based on the control parameters.

An unmanned undersea vehicle includes one or more vehicle sections. The sections include a vehicle hull. The vehicle includes a data crypt configured to be selectively removable from the vehicle through the hull of the vehicle. The data crypt includes a persistent storage device configured to operate using SATA protocols and one or more electrical connectors configured to selectively connect the data crypt to electrical equipment in the vehicle, wherein the connectors are impedance matched to mating connectors in the vehicle.

Disclosed is path planning system and method for sea-aerial cooperative underwater target tracking, the method comprises: obtaining the position information of a detection target, carrying out a first path planning along a channel of sea surface monitoring device according to the position information of the detection target; carrying out a second path planning along the channel of sea surface monitoring device according to the water surface navigation map and its own position information, constructing an underwater obstacle map; performing a third path planning according to the underwater obstacle map, and tracking to the position of the detection target to complete the tracking task. This disclosure adopts the collaborative optimization of several clusters to reduce the number of iterations and improve the optimization efficiency, making the path planning reasonable, as a result, the target position can be quickly tracked, and the autonomous collaborative tracking capability is improved.

The underwater vehicle with variable configuration (1) comprises: a hull (2) consisting of at least four elongated elements (20), mutually articulated by means of joints (21), to form a first closed polygonal structure (F1), arranged on a plane; thrusters (3), associated in parallel with said elements (20) of the hull (2); actuating means (22), associated with said joints (21), provided for automatically modifying said first closed polygonal structure (F1), from an elongated shape configuration (AF1) to an expanded shape (EF1), corresponding to an elongated conformation of said hull (2), to determine a low hydrodynamic resistance and a longitudinal thrust of the thrusters (3) in the cruising of said underwater vehicle (1), and to a substantially isotropic conformation, wherein the same elements (20) of the hull (2), as well as the thrusters (3) are mutually angled, intended for the hovering of the same underwater vehicle (1), respectively. The latter can be suitably equipped with robotic arms (4) intended for performing maintenance or similar interventions in underwater locations.

Disclosed is a sonobuoy that houses at least one unmanned vehicle that may be launched from the sonobuoy. The sonobuoy may include a canister, a parachute, an unmanned vehicle, and a launch mechanism. The parachute may be disposed within an interior cavity of the canister proximate to a first end of the canister. The unmanned vehicle may be disposed within the interior cavity of the canister proximate to a second end of the canister. The launch mechanism may be disposed within the interior cavity of the canister and operatively coupled to the unmanned vehicle. The launch mechanism may be configured to launch the unmanned vehicle from the canister. The sonobuoy may further include a launch deployment mechanism that may be configured to orient the canister with respect to a surface after the sonobuoy impacts the surface in order to facilitate the launch of the unmanned vehicle.
