In the history that Zhang Wenhao knows, the final result of C929G is a failure, although the core engine is not domestic, but the engine provided by General Electric, but there are many reasons for the failure, such as: the backwardness of avionics equipment; uneven performance of the whole machine; Most of the parts of the whole aircraft are not common to Boeing and Airbus, and the cost of maintenance and man-hours increase.

The reason why Boeing can form a worldwide monopoly with Airbus is not only to rely on their leading technical strength, but also a large part of the reason is that each of them has expanded its own product line, not only 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 their own brand aircraft, and every airport in the world has a large number of spare parts for their own aircraft at any time for repair and maintenance. This is especially important for an industry such as civil aviation, which emphasizes safety.

History proves that the failure of C929G is a failure caused by the lack of integrity, not a single link has gone wrong, now, the country is aiming at the new materials that will be produced by COMAC, even if they really sell the new materials to them, the result is still the same, their products, that is, C929G, which will come out soon, will eventually end in failure.

Regarding Nie Minhui's purchase intention of COMAC, Zhang Wenhao did not refuse, and responded to Nie Minhui easily, saying: "Aunt Nie, except for the materials required by Dongchen Automobile, the rest can be sold to them first, but in terms of price." They don't expect us to give any discounts, everything goes according to the market price. ”

"Why?" Nie Minhui asked curiously, "Don't you give a preferential price?" After all, it is a key project of the state. ”

"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, civil aviation in the future." It will be a battle between Boeing and Airbus, and for other countries, they want to reverse this pattern. It's a fool's dream. ”

Nie Minhui was a little incomprehensible, and said, "Isn't the outside world quite optimistic about COMAC?" The affirmation of the C929 is also very high. ”

Zhang Wenhao shook his head and said, "Useless Aunt Nie." It's all just some friendship shouting, you should know that many industrial technology industries, indeed have already formed a monopoly phenomenon that is extremely difficult to change, take the CPU of civilian computers as an example, it used to be inter and AMD, but AMD is gradually losing the market, inter is more and more likely to dominate the entire market, we are also studying Loongson, but. Loongson has lagged behind others for too many years, and we expect Loongson to one day go hand in hand with inter, to be honest, this is simply impossible, and the same is true for COMAC. McDonnell Douglas was acquired by Boeing, Bombardier only produced regional small passenger aircraft, passenger aircraft made in the former Soviet Union and Russia, and now only North Korea and other third world countries are still in use. ”

Nie Minhui glanced at Zhang Wenhao. Asked: "Then you mean to say that COMAC has no prospects for development at all?" ”

"Hmm." Zhang Wenhao nodded and said: "The current capacity is simply not enough to develop and manufacture trunk airliners, if COMAC wants to develop aircraft with more than one hundred and fifty seats, I dare to say that they will definitely fail." ”

"Hey." Nie Minhui said helplessly: "We have experienced too many tragic cases that have worked hard for several years or even longer, but in the end they were in vain, and I hope that COMAC can create a miracle and not waste the expectations of the whole country on it." ”

Zhang Wenhao shook his head silently, civil airliners, especially trunk airliners with more than 150 seats, can be said to be the most high-tech products in the civilian field, and are the culmination of all cutting-edge technologies. 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, so what can COMAC do to compete with others?

unless

Unless it can produce a new turbofan engine that leads the world, then the C929G may still gain a certain market share due to 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 to trial produce three materials by using various equipment and convenience provided by Zhongyu Group.

Now that it has passed the test, the next step is to start mass production, Zhongyu Group's original production lines for the new material business have all been divided, and other own production lines have also tried their best to give the green light to the production of new materials.

Zhang Wenhao is in Zhangjiakou, not far from Yanjing, at this moment, all the equipment ordered by his Nie Minhui has begun to be delivered one after another, and the rest will be in place in the near future, and the five-axis linkage processing platform equipment has also been delivered, and it is being installed and debugged in Zhangjiakou in full swing.

Jiangcheng's industrial base is in the construction of infrastructure, and the construction of infrastructure, even if it adopts the design of heavy steel structure, will take at least half a year to be delivered, before delivery, Zhang Wenhao can only temporarily build a high-precision machining center in Zhangjiakou, together with the engine production line.

At the same time, the engine production line has also been greatly improved, and the workers found that a large number of foreign technicians began to install the mechanical arm on the production line of the factory according to an accurate installation construction drawing.

Those robotic arms are long or short, some robotic arms, fully extended length of up to five or six meters, mechanical joints are four or five, flexible like snakes, workers are very clear, the introduction of these robotic arms will represent a higher degree of automation in the factory, but this also makes workers begin to worry, the higher the degree of automation, the lower the need for labor, the factory is now upgrading automation, so the next step is not to carry out layoffs?

In just three days, the entire production line, has been installed up to 100 sets of mechanical arms, in addition to those that need to rely on manual completion of the steps, the entire production line, are within the coverage of the mechanical arm, for such a huge number of robotic arms, the manufacturer of the robotic arm is also very surprised, if you want to develop a set of software that can make these hundreds of sets of robotic arms work together, the development cost may not be lower than the robotic arm itself.

After the installation work was completed, Paul, the project leader from the British head office, led Zhang Wenhao to accept and test the robotic arms on the entire production line one by one, each robotic arm has three arteries, one is a cable, which is used to give the most basic power source; One is the hydraulic line, the robotic arm moves flexibly, relying on the collaborative 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 rocker device in his hand, every time he arrives in front of a robotic arm, he will connect the data port of the rocker device with the data port of the robotic arm, and then, use the rocker equipment to control the robotic arm to complete the demonstration action of each component and each joint, after all the equipment is checked, Zhang Wenhao and Paul signed together on 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 what these children can be educated into, it depends on you." ”…,

Zhang Wenhao smiled slightly, knowing in his heart that Paul regarded these robotic arms as his own children, but these children were a blank slate, and what they did, what kind of achievements and products they made depended on their scientific research strength.

After Paul and his entourage left the factory, Zhang Wenhao immediately connected all the mechanical arms to the master control computer, and now the master control computer is still a blank, it does not have any command program to accurately control the more than 100 sets of mechanical arms, but it doesn't matter, Zhang Wenhao has made a certain degree of changes to the master control computer, the computer is equipped with a wireless network card, and Zhang Wenhao has set up a high-end, high-speed network base station in this factory, and the high power is enough to make the wireless signal cover the entire factory.

If you are in the factory, Xiao Er can directly control the master control computer through the internal LAN, and issue instructions to it, if you are in other places, as long as you ensure that Xiao Er can connect to the network, Xiao Er has a way to connect with the master control computer here through the Internet to ensure complete control of the equipment.

Everything is ready, and the workers in the factory have already left work, Zhang Wenhao closed the entire plant, looking at the production line with bright lights but no workers, Zhang Wenhao said to Xiao Er: "Xiao Er! Show me both hands! ”

Immediately afterwards, Zhang Wenhao suddenly found that the mechanical arm on the entire production line suddenly moved at the same time! All the robotic arms are doing a movement at the same time, a salute-like action, the steps are very neat, and then, each robotic arm is doing a variety of actions that are completely different from other robotic arms within their respective working radius, with extremely fast speed and high accuracy.

Xiao Er said with some excitement: "Boss, I can control it easily, this feeling is very good!" ”

Zhang Wenhao is also very satisfied, in this way, this production line, in the process, can be as close to their own requirements as possible, but also the maximum extent of the industrial skills package of products manufacturing, now, the production line has been transformed, and so on Zhongchen new materials company will be a batch of raw materials to deliver, this production line can start construction.
