The invention provides a manless underwater vehicle. The manless underwater vehicle comprises a pressure hull, a vehicle bow and a vehicle stern, wherein the vehicle bow and the vehicle stern are arranged at two ends of the pressure hull, a liquid control system which is used for controlling the liquid flow is arranged in the pressure hull. The manless underwater vehicle is characterized in that adjustment cabins are respectively arranged between the vehicle bow and the pressure hull and between the vehicle stern and the pressure hull, a piston which divides each adjustment cabin into a liquid storage cabin and a water discharging cavity is arranged in each adjustment cabin, the piston is controlled by the liquid control system and does reciprocating movement in the adjustment cabin, and a permeable hole which is communicated with outside part is formed in the water discharging cavity. The manless underwater vehicle is simple in structure, convenient to arrange, huge in adjustment ability and capable of adjusting trim gestures.

An assembly for launching bodies from an underwater platform having a pressure hull, and an outer hull subject to free flooding. The assembly includes a module having a proximal end outboard of the pressure hull portion of the platform, a distal end disposed proximate and in alignment with a launch opening in the outer hull portion, and a chamber in the module extending from the distal end of the module to proximate the proximal end of the module, the module chamber being adapted to receive and retain one of the bodies. Support structure on the platform retains the module. A pump on the platform is in communication with water outside the pressure hull, and an impulse tank on the platform is in communication with the pump. A manifold is in communication with the impulse tank for directing outflow of water from the impulse tank to the chamber to eject the body from the chamber.

A submersible vessel having wing and keel assemblies that are extendable for wind-powered surface operation and retractable to reduce drag for submerged operation or to place the vessel in a more compact configuration. A deployment mechanism including an actuator and linkage pivots the wing and keel assemblies simultaneously between the deployed and retracted configuration. The vessel may have first and second pressure hulls flanking the wing and keel assemblies. A drive mechanism including a motor and a gear train employing pulley-and-cable assemblies rotates either the wing and flap together such that the flap angle relative to the wing is constant, or to change the flap angle relative to the wing with the wing angle of incidence held constant. The invention also provides a retractable wind-powered propulsion apparatus that is mountable to the hull assembly of a submersible or non-submersible vessel.

The operational amplifier, the sensitive resistance mounting plate, the operational amplifier mounting plate, the data acquisition unit mounting plate, the data acquisition unit expander board, the data acquisition unit and a data acquisition unit are mounted in a pressure hull, connected with an external couple sample and the reference electrode through a cable and a multicore cable. The device has the advantages of simple and compact complete machine structure, simple operation of laying and recovery, safe and reliable using performance, long service life.

The invention belongs to the technical field of underwater vehicle navigation safety protection, and particularly relates to an underwater vehicle protection device and method based on depth control. The device comprises a mechanical depth detection device, an electromagnet, a weight, a power supply circuit and a detection circuit, wherein the mechanical depth detection device and the electromagnet are arranged on a pressure hull of an underwater vehicle and contact with water outside the underwater vehicle, the mechanical depth detection device and the electromagnet are in series connection in the same power supply circuit, the electromagnet attracts the weight when the power supply circuit supplies power, and the power supply circuit is connected with a main control computer of the underwater vehicle through the detection circuit. The method includes that when the water pressure outside the underwater vehicle reaches a trigger water pressure, a normally-closed contact of the mechanical depth detection device is opened, the power supply circuit of the electromagnet is opened, without the attraction of the electromagnet, the weight can detach from the underwater vehicle, and a bigger positive buoyancy and a bigger bow-buoying moment enable the underwater vehicle to float upwards automatically. The underwater vehicle protection device based on the depth detection is simple in structure, reliable in work and independent of a control system of the underwater vehicle, and can effectively protect the safety of the underwater vehicle.

A submarine (1) has an assembly (3) for deploying a life raft (5), the assembly (3) being located in a well (7) formed outside the submarine's pressure hull (11). The assembly includes a pressure vessel (4) for storing the life raft (5) in a pressurized state. To deploy underwater, a lid (71) covering an opening to the well (7) is released to permit the assembly (3), which is buoyant, to ascend towards the water surface. A sensor (43) determines proximity to the water surface, whereby a pneumatic ram (42) in the pressure vessel is activated to eject the life raft (5) from the pressure vessel (4).

The invention provides a vibration isolation mass rigid vibration isolation structure for a bulkhead of a ship. A vibration isolation mass loop is arranged between a pressure hull and the bulkhead, and is arranged at the position, which is a frame away from the pressure hull, on the edge of the bulkhead, and a partition is used for connecting the vibration isolation mass loop and the pressure hull; and the bulkhead is provided with vibration isolation mass saws, and the vibration isolation mass saws are arranged among equipment installation areas on the bulkhead. A rigid vibration isolation mass composite bulkhead structural form for the ships of the invention has the effect of attenuating and isolating the propagation of structural noise well under the condition of increasing the weight of a bulkhead structure as few as possible.

A modular watercraft capable of both surface and submersible accommodation and transport of passengers. In one embodiment of the submersible watercraft of this invention, the hull comprises air bladders, thereby avoiding the engineering complexity, weight and cost of constructing a pressure hull.

The submarine is equipped with a fluid gas pressure container, in particular for storing liquid oxygen. The liquid gas pressure container is arranged within the pressure hull of the submarine and is surrounded by an outer pressure container which is likewise stored within the pressure hull of the submarine. A device is provided which on exceeding a predefined pressure within one pressure container leads fluid from the pressure container out of the pressure hull.
