Submarine is an essential part of modern navy military equipment system, according to difference of the power system, and can be divided into the conventional power submarine and nuclear submarine, because of the danger of nuclear material technology challenges, countries with nuclear submarine technology developed in the world are in a minority, and had the honour of our country is on the list.
Such as the current 095 to vote to support nuclear submarine, is China's research and development of a third generation of nuclear submarine, the current is still in development, but the people of the nuclear submarine power systems, manufacturing materials to speculation has never stopped, 095 experts predict that China's future nuclear submarine may use titanium alloy as the material of pressure shell, is this why?
And the proportion of titanium alloy is only about 4.5, steel but more maintained at about 7.8, the gap between the obvious, nature is better than titanium alloy.
According to the expert test, under the condition of the same pressure bearing capacity, the buoyancy of the shell made of titanium alloy is twice that of the shell made of steel, so it is more suitable for the construction of nuclear submarine pressure resisting shell. To complete the task, so in practice if nuclear submarines using titanium alloy as a pressure shell, even running malfunction, nuclear submarine sinking speed will slow the speed of the steel shell submarine sank, and is likely to be discharged by the ballast water, discarded or objects is the ballast, power nuclear submarine its own buoyancy.
