According to the “Large Aircraft” WeChat official account, the kickoff meeting for the C929 project was recently held at COMAC (Commercial Aircraft Corporation of China).
Following the opening of the conference, participating experts were divided into six specialized groups: overall aerodynamics, airframe structure, composite structure, avionics, mechanical systems, and propulsion systems, and engaged in a week-long discussion.
He Dongfeng, Chairman of COMAC, stated that as China’s first independently developed intercontinental airliner, the C929 holds significant importance in enhancing the spectrum of domestically produced commercial aircraft and driving the development of the commercial aviation industry.
He Dongfeng previously disclosed that the C929, as a long-range wide-body airliner, is planned to accommodate 250 to 350 seats with a range of 12,000 kilometers.
According to Wu Guanghui, chief designer of the C919 and academician of the Chinese Academy of Engineering, the C929 adopts a green design concept characterized by low fuel consumption, low noise, and low emissions, achieved through various measures to reduce carbon emissions.
For instance, it incorporates comprehensive modular avionics technology to reduce the weight of onboard equipment, employs advanced aerodynamic technologies like new-generation supercritical wings and variable camber wings to enhance aerodynamic efficiency.
The aircraft will use advanced composite materials accounting for over 50% of the structure to reduce weight, utilize high bypass ratio low-noise turbofan engines, and extensively apply biofuels to achieve lower fuel consumption during cruising.
