”There is a Chinese saying, it takes 10 years to sharpen a sword. We have spent 60 years sharpening two swords. And they are the best.” — Chinese researcher Han Guilai

Imagine a wind tunnel, capable of simulating flights at Mach 30 — that’s 23,000 mph, or, 30 times the speed of sound.

It may sound like science fiction, but in fact, China has built a hypersonic wind tunnel in Beijing which could put the superpower decades ahead of the West, according to a report in UK’s .

Researcher Han Guilai, of the Chinese Academy of Sciences, said that together with another facility, also in Beijing, China will be about 20 to 30 years ahead of other powers.

China and countries such as the US and Russia have invested heavily in the development of hypersonic flight technology including missiles.

The futuristic tech could make it possible for super-fast jets to fly anywhere in the world in two hours or less.

It could also make space travel accessible to ordinary people as the hypersonic aircraft could cut costs by more than 90 per cent, reports say.

Wind tunnels have helped China push ahead with the technology.

Instead of using mechanical compressors, Beijing uses chemical explosions to generate high speed air flow.

Fuel burns in the JF-22 at speeds 100 million times faster than a regular gas stove creating shock waves similar to those experienced by jets at hypervelocity.

At America’s most advanced wind tunnel, named the LENS II, simulated flights last 30 milliseconds.

In comparison, JF-22’s average flight simulation can reach 130 milliseconds, Guilai said.

He said: “Our experiment time is much longer than theirs, so the aircraft model can be larger than theirs, and the experiments can be more advanced than theirs.

“This determines our leading position in the world.”

The technology is also hugely important when it comes to weapons. The lethal DF-17 ”carrier killer” can perform extreme manoeuvers as it hurtles at Mach 10 — some 7,600 mph — towards a target; the DF-17 could tear through a big ship like the US Navy’s latest carrier, the USS Gerald R. Ford — putting it out of action.

Shanghai-born Qian Xuesen, considered ”the father of China’s rocket program,” coined the term ”hypersonic” in 1946 after he found that the behaviour of air flow was completely different at five times faster than sound.

Qian single-handedly led China’s space and military rocketry efforts after he was drummed out of the United States during the red-baiting of the McCarthy era.

Upon his return, Qian began a remarkably successful career in rocket science, boosted by the reputation he garnered for his past achievements (in MIT and Caltech) as well as Chinese state support for his nuclear research. He led and eventually became the father of the Chinese missile program, which constructed the Dongfeng ballistic missiles and the Long March space rockets.

A former US Secretary of the Navy, Dan Kimball — later head of the rocket propulsion company, Aerojet — would later say about Qian’s expulsion that it was ”the stupidest thing this country ever did. He was no more a Communist than I was, and we forced him to go [back to China].”
