According to CCTV news reports, at the 15th China Air Show, Air China Co., Ltd. and Commercial Aircraft Corporation of China Ltd. signed the first user framework agreement for the C929 passenger aircraft.Intention to become the world's first user of C929 wide-body passenger aircraft.
According to the official website of COMAC, the C929 is my country's first long-range wide-body jet airliner independently developed in accordance with internationally accepted airworthiness standards and with independent intellectual property rights. It is in the same class as the Boeing 787-9 and Airbus A330-900.
The basic model has 280 seats and a range of 12,000 kilometers., with a cruising speed of Mach 0.85, a maximum take-off weight of 247.5 tons, a maximum landing weight of 190 tons, a maximum take-off field length of 2,900 meters, and a maximum landing field length of 1,900 meters, it can widely meet the needs of the global international and inter-regional air passenger transport market.
According to Wu Guanghui, chief designer of C919 and academician of the Chinese Academy of Engineering, C929 adoptsLow fuel consumption, low noise, low emissionsThe green design concept will adopt a series of means to reduce carbon emissions.
For example, comprehensive modular avionics technology is used to reduce the weight of airborne equipment, and advanced aerodynamic technologies such as new generation supercritical wings and variable camber wings are used to improve aerodynamic efficiency.
Increase the amount of advanced composite materials to more than 50%, reduce the weight of the aircraft structure, use high bypass ratio and low-noise turbofan engines and widely use biofuels to achieve lower fuel consumption in the cruise segment, etc.At present, the aircraft has taken a key step and is undergoing preliminary design work..
