Beijing: Chinese scientists are developing laser propulsion for the next generation of nuclear submarines. With this, Chinese submarines will become completely calm in the sea. In such a situation, it will be difficult to search for Chinese submarines. Chinese scientists say they have found a way to significantly improve the efficiency of laser propellers that could one day propel underwater ships. The researchers said the new technology could generate about 70,000 newtons of thrust using 2 megawatts of laser power emitted through the coating of the submarine’s optical fibers. This is approximately equal to the power of a commercial jet engine. This is an efficiency that was previously considered impossible.
China will create bubbles on the surface of submarines
The laser pulses not only generate force but also vaporize the seawater, creating bubbles over the entire surface of the submarine. This is known as “supercavitation” which can significantly reduce water resistance. According to the researchers, theoretically, this development could allow a submarine to travel faster than the speed of sound without generating mechanical noise vibrations. This will not reveal the location of the submarine. This science fiction-like technology – called “underwater fiber laser-induced plasma detonation wave propulsion” – could have “broad application possibilities in areas such as stealth propulsion for submarines,” he said.
Harbin Engineering University team is creating technology
The project team is led by Ge Yang, Associate Professor of the School of Mechanical and Electronic Engineering at Harbin Engineering University in Heilongjiang Province. China’s first submarine was developed at this place. The leap in technological progress of the PLA Navy’s weapons and equipment in recent years is closely related to this huge institution located in the heavy industrial manufacturing center of Northeast China. The US government has imposed severe sanctions and blockade on more than 30,000 students and scientists of the university.
Submarine will get strength with the help of laser beam
The technology pulses a large number of high-powered laser beams around the submarine from different angles, according to a peer-reviewed paper by GE’s team published in the Chinese academic journal Acta Optica Sinica last month. Ge and his colleagues said, “This method can also be applied to underwater weapons, creating a supercavitation phenomenon, which significantly increases the underwater range of projectiles, underwater missiles or torpedoes.” ”
