Revival of the era of supersonic airliners?... another war without gunfire in the U.S. and China.

China has succeeded in testing an airplane engine that can speed up to four times the speed of sound.

As the U.S. leads the revival of the era of supersonic airliners, China seems to have challenged itself.

"3, 2, 1 launch!"

With the sound of an explosion, the rocket soars into the sky.

It's not a military ballistic missile launch.It tests the performance of commercial supersonic airliner engines mounted on the top of

rocket.

The "Jin the Woo 400" engine, named after the cloud that Son Okong rode.

The developer said the test reached Mach 4, four times the speed of sound, and 5,000 km/h.

[Dengfan / Ling Kong Tianxing Technology Vice President: Experimental data show that the Ramjet engine has been ignited and operated normally. We declare the smooth success of this experiment.

Subsequently, it aims to launch the first test flight of supersonic passenger planes by 2027 and the world's first commercial operation in 2030.

This means that we will follow the timetable of the supersonic passenger plane X-59, which NASA and Lockheed Martin are jointly developing.

The X-59 is already ahead of test flights over the city center by reducing the noise generated by supersonic breakthroughs.

[Fam Meloy / Deputy Director of NASA (January): Supersonic flying creates a huge 'sonic boom'. This means that it will be restricted throughout the densely populated areas. X-59 will break down that barrier.]

The first supersonic airliner in mankind is Concorde, which was jointly developed by the United Kingdom and France.

It succeeded in commercialization in 1976, but it disappeared into history 27 years after the 2000 explosion crash.

Twenty years later, along with technological advances, private startups are re-entering the development of supersonic airliners.

[Cash Savitt / Boom Supersonic CEO (2022)] The biggest luxury in our lives is time. To be able to go anywhere almost twice as fast...]

China is challenging the United States, which is leading the revival of the supersonic airliner era, signaling another war without gunfire.
