In the history that Zhang Wenhao knows, the final result of the c929g was a failure. Although the core engine was not domestically produced, but an engine provided by General Electric, there were many reasons for the failure, such as: backward avionics equipment;
Unbalanced performance; most parts of the entire aircraft are not common with Boeing and Airbus, which increases maintenance costs and man-hours.
The reason why Boeing and Airbus can form a world-wide monopoly is not only due to their leading technical strength, but also a large part of the reason is because each of them has expanded its product line, not only all
Every civil aviation airport in the world has its own aircraft taking off and landing. Every airport in the world also has technicians who can repair and maintain its own brand of aircraft. Every airport in the world has a large number of spare parts used on its own aircraft.
It is available for repair and maintenance at any time, which is particularly important for an industry such as civil aviation that emphasizes safety.
History has proven that the failure of c929g was a failure caused by a lack of integrity, rather than a problem in a single link. Now, the country is targeting the new materials it will produce for COMAC, even if it really sells the new materials to
For them, the result is still the same. Their product, which is the c929g that will be released soon, will ultimately end in failure.
Regarding COMAC's purchase intention mentioned by Nie Minhui, Zhang Wenhao did not reject it and responded to Nie Minhui easily, saying: "Aunt Nie, after excluding the materials required by Dongchen Automobile, the rest can be sold to them first.
But in terms of price, they shouldn’t expect any discounts from us, everything will be based on the market price.”
"Why?" Nie Minhui asked curiously: "Don't we give you a preferential price? After all, it is a key national project."
"So what about key projects." Zhang Wenhao smiled slightly and said: "Don't worry, Aunt Nie, judging from the current trend, they will not succeed. In fact, the future of civil aviation will be a battle between Boeing and Airbus.
, for other countries, wanting to reverse this pattern is simply nonsense.”
Nie Minhui was a little confused and said: "Aren't the outside world quite optimistic about COMAC? They are also very positive about the C929."
Zhang Wenhao shook his head and said: "Useless Auntie Nie. It's all just friendly shouting. You should know that many industrial technology industries have indeed formed a monopoly that is extremely difficult to change. Take the CPU of civilian computers as an example.
In the past, Inter and AMD were the two dominant players, but AMD is gradually losing its market. Inter has become more and more likely to dominate the entire market. We are also studying Loongson, but Loongson has lagged behind others for too many years. We hope that Loongson will one day
To be honest, it is impossible to keep pace with Inter. The same is true for COMAC. Several large aircraft brands of the year have lost out in the competition. McDonnell Douglas was acquired by Boeing, and Bombardier only produces regional small passenger aircraft.
, passenger planes produced in the former Soviet Union and Russia are now only used by North Korea and other third world countries. Under this situation, how is it possible for COMAC to eat up a fat man in one go?"
Nie Minhui glanced at Zhang Wenhao and asked: "Then you mean to say that COMAC has no development prospects at all?"
"Yeah." Zhang Wenhao nodded and said: "The current capabilities are simply not enough to develop and manufacture mainline passenger aircraft. If COMAC wants to develop aircraft with more than 150 seats, I dare say they will fail."
"Hey." Nie Minhui said helplessly: "We have experienced too many tragic cases where we have worked hard for several years or even longer, but in the end it was in vain. We hope that COMAC can create some miracles and not waste the efforts of the whole country.
The expectations it raises.”
Zhang Wenhao shook his head silently. Civil aviation airliners, especially mainline airliners with more than 150 seats, can be said to be the most technologically advanced products in the civilian field. They are the culmination of all cutting-edge technologies. There are so many developed countries in the world, but only Boeing and Airbus
There are two brands, and there are only ten main models in production! Boeing 737 to 787, six models; Airbus A320, 30, 50 to A380, four models.
The entire market has already been transformed by Boeing and Airbus. How can COMAC compete with others?
unless...
Unless it can produce a new world-leading turbofan engine, in that case, the c929g may still gain a certain market share with its advantages of high performance, low fuel consumption and low maintenance costs.

The newly established Zhongchen New Materials Research and Production Company, under the leadership of Chen Rongguang, began trial production of three materials using various equipment and conveniences provided by Zhongyu Group. Only half a month later, this
All three materials were trial-produced, and after final monitoring, all indicators were indistinguishable from those stated in Zhang Wenhao's documents.
Now that it has passed the test, the natural next step is to start mass production. All the production lines originally provided by Zhongyu Group for the new material business have been divided, and other self-owned production lines have also tried their best to give the green light to the production of new materials. Although batch production
Production has already begun, but due to excellent confidentiality work, no relevant news has been revealed.
Zhang Wenhao is currently in Zhangjiakou, not far from Yanjing. All the equipment he ordered from Nie Minhui has begun to be delivered, and the rest will be in place in the near future. The five-axis linkage processing platform equipment has also been delivered and is in progress.
Intense installation and commissioning in Zhangjiakou.
Jiangcheng's industrial base is in the process of infrastructure construction, and the infrastructure construction, even if it adopts the design of heavy steel structure, will take at least half a year to be delivered for use. Before it is delivered for use, Zhang Wenhao can only
The high-precision machining center is temporarily built in Zhangjiakou, together with the engine production line.
At the same time, substantial improvements were also made on the engine production line. The workers discovered that a large group of outside technicians began to install the robotic arm intensively on the factory production line according to a precise installation construction drawing.
Those robotic arms may be long or short. Some robotic arms are as long as five or six meters when fully extended. The mechanical joints are as large as four or five and are as flexible as snakes. The workers know very well that the introduction of these robotic arms will
It means that the factory needs to carry out a higher degree of automation, but this also makes workers start to worry. The higher the degree of automation, the lower the labor required. Now that the factory is undergoing automation upgrades, will the next step be to lay off employees?
?
In just three days, as many as a hundred sets of robotic arms were installed on the entire production line. Except for those steps that required manual work, the entire production line was covered by the robotic arms.
Within, the manufacturers of the robotic arms are also very surprised by the huge number of robotic arms used. If they want to develop a set of software that can allow hundreds of robotic arms to work together, the development cost will probably be no more than the robotic arms themselves.
Low.
After the installation work was completed, Paul, the project leader from the British head office, led Zhang Wenhao to inspect and inspect the robotic arms on the entire production line one by one. Each robotic arm has three arteries and one is a cable, which is used to provide the final
The basic power source; one is the hydraulic line, and the flexible movement of the robotic arm depends on the cooperative work of the hydraulic components of each part; the third is the data input port, which is used to input all instructions.
Paul has a joystick device in his hand. Every time he comes to a robotic arm, he will connect the data port of the joystick device to the data port of the robotic arm. Then, he uses the joystick device to control the robotic arm to complete various components and joints.
After the demonstration actions and all equipment were inspected, Zhang Wenhao and Paul jointly signed the acceptance form.
Paul got the acceptance form and said to Zhang Wenhao in an authentic London accent: "I have sent you the children. As for how these children can be educated, it is up to you."
Zhang Wenhao smiled slightly and understood in his heart that Paul regarded these robotic arms as his own children, but these children were just a piece of blank paper. What they did and what achievements and products they made depended on his own scientific research.
Strength.
After Paul and his team left the factory, Zhang Wenhao immediately connected all the robotic arms to the master control computer. The current master control computer was still blank. It did not have any command programs to accurately control the more than one hundred sets of robotic arms. However,
It doesn't matter, Zhang Wenhao made some changes to the main control computer. The computer was equipped with a wireless network card, and Zhang Wenhao set up a high-end, high-speed network base station in this factory, with high power enough to allow wireless signals to cover the entire factory.
If you are inside the factory, the waiter can directly control the main control computer through the internal LAN and issue instructions to it. If you are elsewhere, as long as you ensure that the waiter can connect to the network, the waiter can use the Internet.
, connected to the master control computer here to ensure complete control of the equipment.
Everything was ready, and when all the workers in the factory had finished get off work, Zhang Wenhao closed the entire factory. Looking at the brightly lit production line without a single worker, Zhang Wenhao said to the waiter: "Waiter! Show me your hands. Look!”
Immediately afterwards, Zhang Wenhao suddenly discovered that the robotic arms on the entire production line suddenly moved at the same time! All the robotic arms were making an action at the same time, an action similar to a salute. The steps were very neat. Then, every robotic arm
Each of them performed various actions within their own working radius that were completely different from other robotic arms, with extremely fast speed and extremely high accuracy.
The waiter said excitedly: "Boss, I can control it very easily. It feels very good!"
Zhang Wenhao is also very satisfied. In this way, this production line can be as close as possible to his own requirements in terms of technology, and can also produce the products in the industrial skill package to the maximum extent. Now, the production line has been transformed, etc.
Chen New Materials Company will deliver batches of raw materials, and construction of this production line can begin.
