The invention concerns an underwater vehicle equipped with electrochemical means of electrical power generation, characterised in that it comprises a data processing unit (2) with inputs connected to sensors (4) of a parameter selected from amongst temperature, pressure, and hydrogen concentration, water in the area of the vehicle, and the electrochemical means of the engine, and with outputs connected to means (5) of transmitting signals to transmit signals authorising (or not authorising) an operator to approach the vehicle, depending on whether the sensed value of the parameter of the electrochemical means is in a predetermined range around the value of the parameter corresponding to water in the area of the underwater vehicle.

A submersible vessel comprising: an elongated hull; at least one propeller mounted on a forward end of said hull and adapted to move said hull through water; said at least one propeller being of a size and configuration such that when it is rotated at an appropriate speed, it generates supercavitated water flowing from said at least one propeller and then along an outer surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high underwater speeds.

The apparatus of the present invention utilizes the heat energy of a weapon propulsion system to produce a vapor explosion. It includes an outer shell with a nozzle port and a body being made from a metal. The body surrounds a propulsion device and captures its waste heat to heat metal within the body. An explosive device is embedded in the body and can explode on transmission of a signal whereby the heated metal within the body produces a vapor explosion that significantly enhances the effectiveness and lethality of the weapon. The apparatus also discloses a second metal in the body and a heat shield for further enhancing effectiveness.
摘要:
The apparatus of the present invention uses waste heat generated by a weapon propulsion system to melt and ultimately superheat metal. Upon termination of the weapon mission, the apparatus explodes thereby causing molten and superheated metal to be instantly introduced to the liquid medium through which the weapon travels. The reaction of the molten and superheated metal with the liquid medium produces a vapor explosion that significantly enhances the effectiveness and lethality of the weapon.

An induced flow underwater vehicle motor cooling jacket adaptable to an urwater vehicle motor is provided. The cooling jacket has a self-priming inlet incorporated into the afterbody motor shell section which ingests seawater during either vehicle movement through the water or operation of the vehicle motor. The motor cooling jacket has a coiled tubing assembly, forming a heat exchanger with a variable tube cross-section, wrapped tightly around the motor. One end of the tubing is attached to the self-priming inlet and the coolant discharge nozzle at the opposite end of the tubing exhausts to the region immediately ahead of the vehicle propeller. Solder is applied between each coil to maintain strength and the tightly wrapped configuration of the cooling jacket.

A dual speed fluid control apparatus is provided which includes a valve b having a high pressure passageway and a low pressure passageway extending vertically therethrough in a spaced apart relationship. A top portion of the passageways is interconnected by a top plenum, a middle portion of the passageways is interconnected by a middle plenum, and a bottom portion of the passageways is interconnected by a bottom plenum. The valve body has the following: an ambient pressure inlet into the top plenum, a fluid bypass outlet into the middle plenum, and a pressurized fluid inlet and fluid outlet into the bottom plenum. A valve is located within each passageway and is responsive to pressure in the bottom plenum for bypassing fluid from the bottom plenum to the middle plenum. A spring biased device is located in each passageway and is responsive to the ambient pressure in the top plenum for pushing each valve toward the closed position against the pressure in the bottom plenum. The spring bias on the push device in the high pressure passageway is greater than the spring bias on the push device in the low pressure passageway. A control valve device is provided for selectively opening and closing the bottom portion of the low pressure passage way to the bottom plenum. With this arrangement the fluid control apparatus will supply high pressure fluid when the control valve means is closed and will supply low pressure fluid when the control valve means is open, both of these pressures and flow rates being varied by the magnitude of the ambient pressure in the top plenum.
