Changing CO2 cycles and resulting concussions of long-term unmanned underwater vehicles

摘要

The carbon dioxide circulation generation system 100 includes reservoirs 101 and 102 for collectively storing a portion of the carbon dioxide liquid and gas 109 and 111 and a transfer connection portion 103 for selectively directing the flow of carbon dioxide through the turbine 106, . Between different seawater depths, the system cycle is to utilize at least one of seawater pressure and seawater temperature to produce a carbon dioxide flow. The inlet / outlet control valves (107, 108) on the variable volume tanks, located below the movable pistons in each tank, selectively enable the seawater (110, 112) from the bottom of each tank below the piston When it is deeper than near the surface, pressurizes the internal carbon dioxide relative to the carbon dioxide inside the other tank. Restricted versus unrestricted heat transfer between the reservoir portion and seawater allows different sea water temperatures at and near the surface to produce carbon dioxide flow. The acoustic communication can be driven simultaneously with the turbine.
