Flying-Wing Airliner Concept Moves Closer to Reality
Aerodynamics researchers in China have tested an 800-passenger flying-wing aircraft model, according to a report released at 14:00 on August 19 by the China Aerodynamics Research and Development Center (CARDC). This latest disclosure highlights China's broader push to advance its aerospace sector. The design has an 85-meter wingspan, roughly 1.6 times the span of the U.S. Air Force's B-2 Spirit bomber. Its wing area is approximately 1,395 square meters, and cruise speed is projected at Mach 0.8.
Wind Tunnel Trials and Next Steps
To validate the concept, the team built a stainless-steel model at 1:52 scale. That test article is about 0.8 meters long with a wingspan of 1.6 meters. It was tested in the institute's 2.4-meter transonic wind tunnel at speeds ranging from Mach 0.4 to Mach 0.8. Below Mach 0.7, the model achieved a maximum lift-to-drag ratio of roughly 20; at Mach 0.8, that ratio fell to 17.6.
The project originally started as a 250-passenger concept before CARDC scaled it up to 800 seats. Researcher Li Yonghong and his team are named in the report.
- On August 12, China's C919 jet made its first scheduled international commercial flight.
- Air China operated the C919 from Beijing to Ulaanbaatar.
- The trip lasted about two hours and is now flown daily.
That flight is the C919's first commercial operation beyond China, although the aircraft still lacks certification from American and European aviation regulators. Its engines are produced by CFM International, a joint venture between GE Aerospace and Safran.
The flying-wing concept could reshape commercial aviation as China works to strengthen its position in the global airliner market. The C919's international debut adds to that momentum, but certification challenges and competition with established manufacturers remain. If the new design eventually enters service, it could help China solidify its standing in the aerospace industry.
As China's aerospace ambitions gain momentum, the recent successful flight of a new C919-600 variant tailored for high-altitude airports further underscores the nation's commitment to advancing its commercial aviation capabilities. This development complements the testing of the innovative flying-wing concept, suggesting a strategic push to enhance performance across diverse flight environments.
