A submarine is comprised of a hull with an external seat on top and a backrest behind the seat. A control column and a grab handle are positioned in front of the seat. External drive motors attached to the hull drive propellers housed in protective cages. Servo driven dive planes and stern rudders provide directional control. Batteries are attached to a mounting plate positioned in channels inside the hull. The control column, drive motors, dive planes, rudders, and batteries are connected to a ...

A submarine is equipped with an extending apparatus on whose free end a container (4) resistant to underwater pressure is arranged, in which an essentially recoil-free gun (5) lies. The container (4) in the submerged condition of the submarine may be brought to the water surface (15) by way of the extending apparatus, and pivoted out so that one may also shoot in the submerged condition.

A submarine has a forward pressure hull, an aft pressure hull, and a third pressure hull vessel which is connectable to each of the forward and the aft pressure hulls, wherein the submarine is provided with an array of tubes suitable for launching missiles, the tubes being disposed between the forward and the aft pressure hulls, generally around or adjacent to the center of buoyancy of the submarine.

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.

A cargo submarine has a cargo section (2) between tapered peripheral buoyancy sections (2-5) and an on-board cargo-handling components (32-49) capable of rapid loading and unloading of large volumes of cargo. A hydrodynamic tower (14) conveys fresh air in and exhaust gasses out while traveling submerged sufficiently deep to avoid wave undulation. Dual electronic controls (51-57) in a tower bridge (27) and in a main bridge (50) are provided for large vessels. A crane (32) with automatically-adjus...

A submarine boat provided with a fuel cell (30) for power generation by supply of hydrogen and oxidizing agent, a hydrogen generating device (10) for generating a gas containing hydrogen to be supplied to the fuel cell, and propelling device driven by electricity generated by the fuel cell, characterized in that the hydrogen generating device is to generate a gas containing hydrogen by decomposing a fuel containing an organic compound, comprising a partition membrane (11), a fuel electrode (12) ...

A flooded bin measurement system is provided that includes a submarine sampler for ascending and descending within a liquid of a bin and for measuring the depth of fluid at the submarine sampler's location. In one embodiment, the submarine sampler may ascend and descend along a vertical guide based on adjustments to it buoyancy compared with the liquid in the bin, which may be controlled manually and/or automatically. The measurement system may include a bubbler system for measuring hydrostatic ...

In a submarine weapon, particularly for combating submarines, a rocket engine with continuous rocket thrust is utilized as the submarine drive unit. An actively locating, acoustic target seeking device is provided for target detection and target pursuance, the ranging frequency of which is selected so that the echo level to be expected from its detection range lies above the noise level of the rocket engine.

A submarine includes a body and two ballast tanks. The ballast tanks are moveable from an up or diving configuration to a down or beach configuration. With the ballast tanks in the diving configuration and full of water, the submarine normally floats awash, and can be caused to dive at shallow depths for sight-seeing. With the ballast tanks full of air and in the beach configuration, the body will float substantially out of water, and the submarine may be beached or brought to a wharf for easy b...

A model submarine has an inherent "fail safe" feature, so that the submarine (if submerged) will rise to its periscope depth in the event the submarine encounters a stationary object, or in the event a power failure occurs. Power is supplied by a single submersible motor-pump unit within a free-flooding hull. The motor-pump unit supplies a pressurized water discharge for, first, forward propulsion of the submarine via the discharge nozzle of an ejector pump; and second, for hydraulic control of ...
