China's ultrasound submarine runs to the US in 100 minutes

China has taken a step closer to the ambition to create an ultrasound submarine that could move from Shanghai to San Francisco in less than two hours.

South China Morning Post reported that scientists at the Harbin Institute of Technology succeeded in piloting a small submarine that achieved extremely high speeds in the environment. country.

Professor Li Fengchen of the research institute said, this is the technology 'bubble' (Supercavitation) . This means that gas bubble bags will cover almost the entire ship so that it comes into contact with water at least, thereby reducing drag and friction with water. "This is a very complex technology, but we are delighted to find out its prospects ," he said.

Difference between conventional submarines and submarines using Supercavitation technology

Technically, this technology was not thought by the Chinese, it was a Soviet achievement in the Cold War.

The Supercavitation helped the Soviet Union create the fastest Shakval torpedo at 370km / h.

The theory of Supercavitation can help the object move in water with a maximum speed up to 5,800km / h. At present, Chinese scientists are confident to build a vessel that achieves this velocity, thereby facilitating transatlantic travel in just 100 minutes.

There are two difficult issues with submarines using Supercavitation technology. Firstly, it is about making it to 100km / h (to create and maintain air bubbles). The second is how the ship controls its rudderless contact with water.

The new submarine model is believed to be China

According to Professor Li Fengchen, Chinese scientists have resolved both issues, but declined to elaborate. And that moving under the water is as easy as flying in the air.

Professor Wang Guoyu, head of the Fluid Mechanics Lab at the Beijing Institute of Technology, said that over the years the world has struggled to find a technical solution to the Supercavitation technology and now China has found the answer. This will be a breakthrough for the Chinese Navy to change its balance at sea.
