According to a study by scientists involved in Chinese missions to Mars and the Moon, China is developing a supersonic aircraft which is larger than the Boeing 737.
The aircraft is 45 meters long, nearly a third longer than the Boeing 737-700, with two aspirated engines on top of the fuselage. The design has a pair of delta wings similar to those of the Concorde, but with the wingtips pointing upward. Such a complex design poses multiple aerodynamic challenges when the aircraft enters hypersonic speeds or exceeds five times the speed of sound. Researchers are using a new aerodynamic model to evaluate the aircraft’s performance at high altitudes and has proven effective on China’s latest space missions.
Liu Rui from the Beijing Institute of Technology and collaborators from the Institute of Aerospace Systems Engineering (宇航系统工程研究所) published a paper in the journal Physics of Gases. Liu was a key scientist on the Mars landing and lunar rock sampling missions. According to official media reports both of these required the spacecraft to fly through the atmosphere at hypervelocity.
