What is the Largest Airplane?

Large aircraft (English name: Large passenger aircraft, also known as large passenger aircraft) generally refers to transport aircraft with a maximum take-off weight of more than 100 tons, including military large transport aircraft and civil large transport aircraft, and also includes military aircraft with a range of 3,000 kilometers or Take a passenger airliner with more than 100 seats.

Three-step plan:

"The first step is to assemble and partially manufacture the mainline aircraft; the second step is to cooperate with foreign countries to jointly design and develop 100-seat aircraft; the third step is to implement it in 2010.

Large aircraft shares runway with Pudong Airport

For the final installation at Pudong Airport, an aviation industry expert analyzed that because the large aircraft project can share the runway with Pudong Airport.

As for the research and development base set up in the Zizhu Science Park, the expert believes that the Zizhu Science Park values its technological atmosphere. In addition, the customer support center of AVIC Aircraft Co., Ltd. and the headquarters and R & D center of AVIC Aircraft are also there.

At the 2008 China International Aerospace Summit Forum held on November 3, 2008, Miao Wei, Deputy Minister of Industry and Information Technology, disclosed four major tasks and goals for the development of China's aviation industry in the next few years. The development of China's large aircraft, which has attracted much attention at home and abroad, will progress in an orderly manner. It is expected that the model design test and trial production will be carried out during the "Twelfth Five-Year Plan", and the model certificate and production license will be obtained during the "Thirteenth Five-Year Plan" and will be put on the market.

Large aircraft developed by China are scheduled to fly for the first time in 2014, and airworthiness certification will be conducted in 2016.

The large aircraft project is progressing smoothly and has been recognized by all parties. The entire process of aircraft design and development generally includes five stages including pre-development, engineering development, detailed design, comprehensive trial production, and airworthiness certification. The large aircraft is scheduled to fly for the first time in 2014 and airworthiness certification will be conducted in 2016. From the first flight to the test flight stage to airworthiness certification, a series of complicated and tedious procedures are required. The test flight included dozens of courses and took a relatively long time. After airworthiness certification, it means that the aircraft's safety design is recognized, and it has obtained a "birth certificate." With this certificate, the aircraft can enter the substantial phase of mass production.

According to the plan, domestic large aircraft are planned to make their first flight in 2014 and deliver routes in 2016.

C919 Head section of C919, the first domestic passenger jet of a large aircraft, goes offline

July 31, 2014: The nose section of the first C919 large jet passenger jet independently developed in China was rolled off the assembly line in Chengdu. Front of the first aircraft

The body, central wing, and aileron were previously rolled off the assembly line in Nanchang and Xi'an, respectively. Other fuselage sections will also be rolled off and delivered in the near future. The first test aircraft is scheduled to begin assembly in the second half of the year. The nose structure is complex, the design and manufacturing are difficult, and it has an important impact on flight performance. It is the most important part of the aircraft.

The head section of the C919 large passenger aircraft is 6.66 meters in length. It is a typical semi-rigid shell metal structure composed of a frame, a stringer, a windshield skeleton, and a skin, including a cockpit cover, a front hatch, a wall panel, and a nose floor. Wait for several major components, involving more than 300 modules and more than 3,200 parts.

The C919 is a large commercial mainline aircraft that can accommodate up to 180 passengers, with final assembly planned for the second half of the year. Looking forward to the large domestic aircraft flying in the blue sky! ^[11]

Delivery of large fuselage domestically produced large aircraft

On August 29, 2014, it was learned from COMAC that the fuselage / center wing and aileron sections of the C919 large passenger aircraft passed the airworthiness inspection of AVIC Xifei on the same day and reached the delivery status, which became the development process of the C919 project. The second major segment of delivery. This also laid a solid foundation for the docking of the first aircraft in the second half of 2014.

Delivery of the fuselage section of a large domestic aircraft

The development of the fuselage section of the domestically produced large aircraft took 6 years from the completion of the preliminary program demonstration to the final assembly.

The center fuselage / center wing section of the C919 large passenger aircraft is located in the middle of the fuselage, with a total length of 5.99m and a width of 3.96m. It is composed of the center fuselage section, keel beam, center wing, and emergency door. . This section contains more than 8,200 parts and involves more than 3400 tooling. In order to improve the overall performance and reduce the structural weight, the middle fuselage / center wing section uses a large number of third-generation aluminum lithium alloys and 2024HDT high damage tolerance aluminum alloy materials. And super-large titanium alloy forgings, this is the first time in domestic civil aircraft applications. The aileron section is located on the outer trailing edge of the wing and is the main control surface of the aircraft. The amount of composite material used has reached 80%. ^[12]

2017 year

C919 taxied after landing safely at Shanghai Pudong International Airport.

On May 5th, China's first international mainstream trunk airliner C919 landed safely at Shanghai Pudong International Airport and made its first flight.

After the successful first flight, the C919 will enter the airworthiness certification phase, which will mean that its distance to the market is further. However, airworthiness forensics will not be a short-term task.
