Everyone knows that Y-10 is China's first domestically produced large passenger aircraft. It is a four-engine large jet passenger aircraft developed by the Shanghai Aircraft Manufacturing Factory of China's Aviation Industry Corporation in the 1970s. This is the first large jet passenger aircraft designed and manufactured by China itself with complete independent intellectual property rights.

Y-10 was launched in August 1970 and completed its design in 1975. On September 26, 1980, the first test flight of the Y-10 was successful, causing a sensation around the world. China became the fourth country after the United States, the Soviet Union, France (Europe) to produce large civil aircraft. It would not be possible not to sensation the world.

Everyone knows that every screw of the Y-10 is purely domestically produced, but what you don’t know is that the Y-10 is also a domestically produced aircraft designed according to the British and American Airworthiness Regulations (CAM4b and later FAR25). After the first test flight of the Y-10 aircraft was successful, the subsequent test flights and transition flights were also very successful. The test flight proved that the performance of the Y-10 aircraft met the design requirements. It is very sad and puzzling to dismount in

Y-10. It is said that it is because of the 30 million yuan test flight fund; it is later that the senior management did not agree to give the funds, so Shanghai decided to raise funds by itself. Later, it is said that the Y-10 project was too successful because it was a project approved by someone in Shanghai and could not be successful. In fact, the Y-10 was a project promoted and approved by Chairman Mao and Premier Zhou. None of these rumors have a reliable basis. In short, after the very successful pure domestic Y-10 dismounted, the chief designer of Y-10 Mafengshan died of depression in 1990, and was only 61 years old. The design of the

Y-10 is based on the H-6, and we refer to the United States' Boeing 707 aircraft, Trident and Soviet map 104 aircraft. Our researchers and scientists do not work behind closed doors as some people say, but learn from advanced international experience. The earliest purpose proposed by the

Y-10 project was to produce and manufacture special planes for leaders, and later changed to passenger planes, and in the future they were changed to leaders' special planes.

Y-10 adopts the layout of 4 domestic turbofan-8 engines under the wing. The aircraft's technical performance indicators are: the practical range is not less than 7,000 kilometers, the cruise speed is 850-900 kilometers per hour, the take-off and run distance is not more than 1,300 meters, the flight ceiling is 12,000 meters, the carrying capacity is 100-120 people, the maximum take-off weight is 110 tons, the maximum commercial load is 17 tons, and the long-range commercial load is 5 tons.

turbofan-8 (WS-8) engine, take-off thrust of 80.07 kiloN, take-off fuel consumption rate of 54.56 kilograms/kiloN·hour. Its performance, life and other indicators were still an advanced aircraft engine in the late 1960s.

Look at these indicators, it seems that the Y-10 is not as unbearable as some people say. If the Y-10 develops normally, it can be imagined that China has long been the world's advanced passenger aircraft power, and a considerable number of the aircraft flying in the sky in China are domestically produced, and purely domestically produced.

There is also a legend that American aircraft experts must visit China and visit the Y-10 aircraft. It is said that some people say that Yun-10 is a copy of Boeing 707, including some of our very senior leaders and civil aviation leaders, and they also said that the reason why the Y-10 project is called the 708 project is 707+1, which makes people's imagination amazing. After seeing our plane, American experts completely denied the leader's statement and praised the Y-10, saying that you have graduated.

China's early aviation projects have cultivated countless aviation talents for our country. This is our valuable asset and the basis for the development of C919. Although the C919 is 40 years late, I think 20 years later, half of the planes in the sky in China will be made in China.
