This is one of several similar articles I've seen over the last couple of years. China seems to be pouring truckloads of money into next-gen aviation, space planes, etc.
China designs hypersonic jet bigger than Boeing 737 with wings like Concorde
14 Jul, 2021
- Researchers used aerodynamic model that contributed to China’s latest space missions
- Official timeline aims by 2035 to operate a fleet of hypersonic aircraft that can transport 10 passengers to anywhere on Earth within an hour
At 45 metres (148 feet), the plane would be nearly a third longer than a 737-700, with two air-breathing engines mounted on top of its main body. The design has a pair of delta wings similar to those of the Concorde, but with tips pointing up.
Such a complex design can bring multiple aerodynamic challenges when the aircraft goes hypersonic, or faster than five times the speed of sound.
