China is progressing: Closer to supersonic submarine

China has made a step closer to making supersonic submarines that from Shanghai to San Francisco could arrive in less than two hours, reports portal Saut Tea Morning Post.

The new technology developed by a team of scientists from the Laboratory for complex flow and heat transfer from the Institute of Technology in Harbin, made ​​it easier for submarines and torpedoes to move under water extremely high speeds, according to the portal.

Lifang Chen, professor of mechanics and engineering fluid, said the innovative approach of this team, caused that they can now create complicated air "bubble" necessary to move quickly under water.

"We are very excited about the potential that it brings" he said, adding that there are still many unknowns to be solved.

Water causes more friction and resistance to movement than air, which means that ordinary submarines can not move as fast as an airplane, according to the portal.

Recalls that during the Cold War, the Soviet military developed a technology called
super-cavitation, which included a "package" submarine inside air bubbles to avoid problems caused by water resistance.

The Soviet super-cavitation torpedo called Ĺ akval able to reach the speed of 370 km / h or more, which was much faster than any ordinary torpedo.

In theory, the super-cavitational vessel could, under the water reaches the speed of sound, or about 5,800 km / h, which, according to the report of California Institute of Technology in 2001, could lead to reduced travel time from one to the other shore of the Atlantic Ocean to less than hour, while traveling from one to the other shore of the Pacific ocean took about a hundred minutes.

This is for now only in theory, scientists are skeptical of the practice.

In addition to Russia, the development of vessels and weapons based on
super-cavitation technology deal with countries like Germany, Iran and the United States, according to the portal.
