Singapore, Vietnam, Laos, Cambodia, Malaysia, Indonesia, recently, domestic commercial aircraft ARJ21 and C919 have carried out demonstration flights in many countries in Southeast Asia. There are both passenger and cargo aircraft, both dynamic flight demonstrations and static tour display ......The confidence and sincerity shown by the delegation of domestic commercial aircraft left a deep impression on the international market.
It's a mule or a horse, and it's pulled out for a walk. The demonstration flight mainly verified the adaptability of commercial aircraft to relevant airports and routes in Southeast Asia, the adaptability of airport ground handling equipment, the applicability of special flight procedures, and the economics of route operations.
C919 and ARJ21 participated in the exhibition and displayed the latest products on the same stage with world-class aviation manufacturers, which not only shows that "Made in China" is moving rapidly towards the mature development of the commercial market, but also means that domestic commercial aircraft have the basic conditions and competition level to enter the international market.
According to the market**, in the next 20 years, the demand for passenger aircraft in the Asia-Pacific market will increase from 3,314 to 9,701. It is believed that this wave of "strength show" can lay a good foundation for the further expansion of the domestic commercial aircraft market.
The highlight moment is exciting, and looking back on the rise of domestic large aircraft, we can better understand the hardships and hardships. In the murmur of "it's better to buy than to build", Yun 10 regretfully died; At a critical moment in international cooperation, we were again shut down by the aviation giants......After learning from the pain, self-reliance has become a firm belief.
However, a large passenger aircraft is composed of millions of parts and components, involving dozens of complex systems such as avionics, environmental control, flight control, etc., and the back of the reputation of "shining jewel in the crown of industry" is a long list of technical difficulties. Take the manufacturing material 7050 aluminum alloy thick plate as an example, the difficulty of casting is the most in the field, and China has not been able to produce it independently.
The members of the project team who are holding back their energy eat and live in the office, stay by the stove 24 hours a day, some people constantly calculate and adjust the concentration ratio of the alloy, and some people improve the temperature of the furnace and the way of cooling......After many years, a mature process plan has finally been formed.
It is also such a tough story that allows us to master 163 key technologies, form 1935 patents, and precipitate 240,000 standards and specifications have strongly supported the soaring of domestic commercial aircraft.
The take-off of domestic commercial aircraft has witnessed the progress of independent innovation in China's aviation industry, and has also consolidated confidence and provided inspiration for the transformation and upgrading of China's manufacturing. If we say that for a long time in the past, we have taken the road of "introducing technology, digesting and absorbing, domestic substitution, and bringing forth the new"; Now, as our exploration road extends more and more to the "no man's land", and the uncertainty of the external environment increases, it is more necessary to pay close attention to independent innovation.
God rewards hard work, hard work is not bullying, ten, twenty, thirty years, there will always be a technological breakthrough. In this process, in addition to scientific researchers sitting on the cold bench, policy support at the national level, collaborative tackling between localities, and support and encouragement at the social level are very important. Giving full play to the spirit of hard work and wisdom and the institutional advantages of concentrating on great things, we are fully confident that we have the ability to achieve more breakthroughs and innovations in key areas and key links.
Core technological innovation is a difficult uphill road, destined to be no easy step, and in the short term, not every investment is so "cost-effective". However, a big country must be able to take a long-term view and calculate big accounts, and believe that the development dividends bred by technological innovation will definitely be able to exceed the return on investment.
For example, a C919 has driven a group breakthrough in new materials, new processes and new technologies in the aviation field, forming a large aircraft industry system that radiates the whole country and faces the world. Some experts estimate that this has brought China a contribution ratio of 1:86 to economic added value and a ratio of 1:9 to employment6. That is, investing 1 yuan can bring 86 yuan of benefits and drive about 10 jobs.
Thinking about it this way, China's industry has 41 categories, 207 medium categories, and 666 sub-categories, and the shortcomings and pain points in each category mean a huge increase in development. Grit your teeth, be unswerving, and make efforts on both sides of the enterprise at the same time, even if you experience heavy mountains and rivers, you will definitely usher in the bright future.
Winning the future, grasping the initiative, and strengthening and expanding the manufacturing industry is the only way. The core of the manufacturing industry is innovation, that is, to master the key core technology. It is hoped that the domestic commercial aircraft will fly high, and I also hope that the story of "releasing cranes and soaring into the sky today" can inspire more people to work together to pursue a broader sea of stars.
