On July 6, 2016, it was a day worth remembering by the Republic. It was also a historic moment in China's aviation industry: China's first large-scale transport aircraft independently researched and developed, Yun-20, was officially installed in the Air Force Aviation Department.
Since then, China has truly owned its own large aircraft. China has successfully ranked among the few countries in the world that can independently develop large-scale transport aircraft of 200 tons.
On the same day, Dapeng rises with the wind and lifts up to 90,000 miles.
The -20-packaged Air Force marks a milestone in the development of major national science and technology major large-scale aircraft and the development of China's long-distance transmission power. It is an important symbol of China's scientific and technological innovation capability and overall industrial level improvement, and has fulfilled the long-cherished wish of the people throughout the country. It has great strategic significance for China's national economic construction, national defense construction, national scientific and technological progress, and industrial transformation and upgrading.
Strong country needs heavy equipment, Kunpeng Wanli is not a dream
In June this year, Xi'an Yanliang Air Base. Two dark gray painted Yun-20 large transport planes slowly exited the hangar. On the high tail, the bright five-star red flag is particularly eye-catching. More than a thousand aviation people gathered around the "children" who struggled for more than 3,000 days and nights, applauding, cheering, tears...
It was officially established in 2007, and it successfully made its first flight in January 2013. It was publicly unveiled at the Zhuhai Air Show in November 2014. In 2015, it was transferred to the north-south test flight. It was officially installed in 2016, and the large transport aircraft “鲲é¹â€ came out of autonomous China. Innovative research and development of large aircraft success.
"The big man, I don't know how many thousands of miles, but also the bird, which is called Peng." - More than 2,000 years ago, Zhuangzi launched the wings of imagination in "Happy Travel" and transformed the god bird "é²²é¹". The development of the Chinese people's own large transport aircraft is the dream of the Chinese people for nearly half a century.
"China must have its own big plane! China's vast territory and long coastline determine the important position of large transport aircraft in national security and national defense; when emergency situations such as earthquake disaster relief and overseas evacuation occur, it is even more calling. The launch and timely and effective support of the national air transport force,†said Shuguang, deputy general manager of AVIC.
The needs of the country are the mission of Chinese aviation people.
At the beginning of 2006, the “Development of Large Aircraft†was written into the National Medium- and Long-Term Science and Technology Development Plan. In 2007, as one of the major special projects for the development of medium and long-term science and technology in the country, the state announced the formal establishment of major technology major projects for large aircraft.
"Strong countries need heavy equipment. Large aircraft is one of the important signs that China is a big country and a strong country. China must have its own independent research capabilities, and must have its own strong air transportation capacity." When receiving the task, China's large transport aircraft The designer and Tang Changhong, who has more than 30 years of experience in aircraft development, made up his mind in his heart.
However, it was easy to develop a large transport aircraft. At that time, only three countries in the world had the ability to develop and produce large transport aircraft. China can be said to start from "zero", and even a drawing for reference is not available. Moreover, as a big country, all countries have protected their own big luck like a baby. By buying technology? Don't even think about it! Only the independent research and development of this road.
The will of the country has played a crucial role.
This is an unprecedented challenge to the Chinese aviation industry and an opportunity to test the combat effectiveness. Nearly 10 million parts and components, more than 400 key technical difficulties, were assigned to Xi'an, Chengdu, Shanghai, Shenyang, Harbin and other national research and manufacturing units. They worked together and eventually became a "fist."
"The development process of the Universiade is to adopt a nationwide large-scale joint and large-scale cooperation layout, with AVIC as the lead unit and integrating the innovative organization management model of nearly 1,000 scientific research and production units in the country." Shuguang said.
In this way, after more than 3,000 days and nights of hard work, they have successively overcome a series of technical difficulties such as design, manufacturing, testing and flight test. Every step of the Universiade continues to write history and create miracles. Three years of development, five years of first flight, nine years of delivery, creating a new record for the development and delivery of similar aircraft in the world.
Show the strength of the great powers and take responsibility for the big country
The Universiade has a beautiful shape, a wide, thick body, and people have given the Universia a pretty cute name: "Fat Girl." And this is the strength of the Universiade.
The founder of Dassault France has said such a sentence, "Any plane that looks beautiful is a good plane." This is indeed true. The Universiade has an obvious late-comer advantage and is the fusion of the latest technological achievements.
In 2014, the Yun-20 aircraft was unveiled at the China Air Show. People were surprised to find that no matter from which angle, the Universiade was so beautiful and domineering. An old airline that has been engaged in aircraft development for a long time can't help but feel that the Grand Canal is so beautiful from the static display or the flight attitude. This is definitely a good airplane!
The "fat" of the Universiade is also an advantage for R&D personnel. The multi-purpose large transport aircraft has the characteristics of high tonnage, wide body and fat body. Universiade can perform long-distance, fast air transportation tasks for various equipment, materials and personnel in complex geographical and meteorological conditions. This is not only because of its large size, but also because it has the ability to have high reliability, long life and complex systems to undertake multiple tasks, and to ensure that it is competitive in the long life cycle by applying new processes and new technologies.
In the view of Professor Fang Bing of the National Defense University, the Grand Canal is the equivalent of China’s key to opening the strategic air force.
He said that the strategic long-range strike and force delivery capabilities, the basic platform is the large transport model. Nowadays, special aircraft developed by many countries are developed on the basis of the Universiade platform. If the large transport aircraft can be fully localized, it means that there is a common platform.
"When the large-scale transport aircraft, strategic bombers, and strategic early-warning aircraft coated with the 'August 1' military emblem are all localized, we can call it the big country air force and the strong national air force." Fang Bing said.
Dawning said that the Universiade will not only be a large-scale military transport aircraft, but will also meet the needs of the country's economic construction and people's livelihood, and will vigorously support the "One Belt, One Road" national strategy; serve the military's modernization and meet the needs from national defense to the expansion of national interests; Responsibility for major powers in disaster relief, overseas evacuation, and international humanitarian assistance.
Can be a big man, can attack the hard, the Universiade team casts the spirit of the Universiade
"The mission of Chinese aviation people to serve the country by air is to build a sword for the country, to promote the country, and to save the crisis. The state has given Chinese aviation people the historical mission of undertaking the Universiade, and the aviation people will fight for the national trust with independent innovation." In the interview, all Chinese aviation people expressed such feelings.
In the memory of Tsing Kwong and the general designer Tang Changhong and the chief manufacturer He Shengqiang who have experienced the development of excessive aircraft, there are many days and nights. They are thinking about a certain key technology, arguing or shaking hands. In order to make the Universiade better and stronger.
With a high degree of innovation, the Universiade team has overcome a series of difficulties and made China's creation reach the height of the world.
In the past 9 years, AVIC has in-depth research on the law of R&D management of large-scale complex aviation systems, actively explored the engineering development management mode combining foreign advanced R&D concepts with China's reality, and built a nationwide industry-wide collaborative development system to achieve large-scale off-site Digital transformation, system hierarchical integration verification, design process integration iteration, modular manufacturing delivery represented the transformation of the development mode, established a multi-objective, multi-element, whole process development management platform, effectively guaranteeing the requirements of rapid project development .
The Chinese aviation people successfully used their own similar aircraft for about half of the time to successfully achieve the first flight, creating a new record for the development and delivery of similar aircraft in the world.
"The task of being able to participate in such an important aircraft model in this life is a valuable asset for a lifetime, and the value of aviation career!" In the interview, the researchers almost always said this.
Twilight has not remembered how many times to coordinate the command of the Universiade project to and from all parts of the country, how many weekends are remembered to see the progress of the Universiade; he once lived for more than 30 days for the first flight of the Universiade. It has also made various considerations for its details and long-term development.
However, the Chinese aviation industry has never carried out such a large-scale project. The outside world and the industry have worried that the Universiade can overcome serious technical problems, and even have doubts that the Chinese-made Universiade can fly up?
Dawn told reporters: "Although we can do our best to ensure the safety and reliability of the Universiade in the development process, in the year before the first flight, I have imagined the day I will face in my mind many times. Such a big plane, flying There are too many possible situations at the moment of getting up. Is there any way to check in advance whether it can take off safely?"
“Finally, we decided to design a test for the aircraft that has never been seen in the aviation industry, so that the test pilot can truly experience the takeoff and landing of the aircraft,†said Shuguang.
He clearly remembers that on January 25, 2013, the test pilot said with confidence after completing this special test that "the aircraft has good maneuverability and can arrange the first flight!"
Upon hearing this, the heavy feelings of the twilight were swept away. The team quickly decided to decide: "Tomorrow, the first flight of the Universiade!"
"Three-year journey, tens of thousands of airlines will remember the mission, overcome difficulties, and climb the new peak of the industry; five years of expectation, all technical elites compete for heavy responsibility, innovation beyond, swear to save the Universiade."
Shuguang said that the first delivery of large-scale transport aircraft is a new starting point for the formation of China's strategic delivery capability, and it is also a new starting point for the new phase of national large-scale aircraft construction. The Chinese aviation people will continue to carry forward the spirit of the great spirit of "great sentiment, great dedication, great leap, great synergy, and great carrying", building the country's heavy weapon, and building a national backbone, serving the national dream and strengthening the military dream, serving the national economic construction and Social development makes new and greater contributions!
