Chapter 545 Seeking Military Help
Yu Shaoguang presided over the meeting.

He seemed to feel the heavy atmosphere in the conference room, and comforted everyone: "Comrades, you don't need to be discouraged. I firmly believe that there must be a way for the car to reach the mountain. The obstacles faced during the trial production process, I think it will definitely be solved."

In fact, as the leader, the pressure on him is also great.

But as the leader of the team, he must maintain full confidence at all times. If even his own confidence is shaken, it will definitely affect the entire team.

Seeing what Yu Shaoguang said, the heavy atmosphere in the conference room seemed to have lightened a bit, and some people looked at Yu Shaoguang with hope.

Yu Shaoguang continued: "We are a team. If we have problems, we will work together to solve them together. How about this? Lao Yi and I will go to Beijing tomorrow to report the situation to the military and seek their help. In addition, you all want to Think of a way, three cobblers are better than Zhuge Liang."

Drones are manufactured for the military, and the military is the strongest backing behind them. If you have any problems, you can go to the military.Yu Shaoguang is going to go to Beijing with Yi Chunhua to report the situation to the military and seek help from the military.

So far, what obstacles have they encountered?
Logically speaking, if there is a complete set of technical data, and the trial production can be carried out according to the technical data, there should be no problems. At the beginning, Yi Chunhua also thought so.

Three months ago, that is, after getting this USB flash drive full of technical materials around mid-November last year, he was ecstatic, as if he had obtained a peerless treasure.

Inspired by the technical data in the USB flash drive, many technical difficulties faced by the new engine they were developing and trial-manufacturing were solved.

Yi Chunhua was full of confidence, thinking that the trial production of this engine would be successful, but the actual situation gave him a severe blow.

As some parts began to enter the trial production stage, they faced two major problems, one was the machining accuracy, and the other was the material problem.

We know that the more advanced the aeroengine, the better the overall performance, the higher the requirements for materials, and the same for machining accuracy.This engine is simply the pinnacle of medium and small turbofan engines, and it also puts forward high requirements on materials and processing accuracy.

However, the research and development of the system is very user-friendly, and it is not abnormal enough to put forward very strict requirements on materials and processing accuracy. If materials can be replaced, materials should be replaced as much as possible. Most of the materials can be produced domestically, or from relevant domestic manufacturers. Manufacturers can purchase.

But there are some key materials that cannot be replaced. They are hurdles that cannot be bypassed. In order to maintain the excellent performance of the engine, they cannot be replaced by low-grade materials. Therefore, such materials can only be imported.

Fortunately, the list of required materials has been given to the military. The military is importing and purchasing through various channels and channels. Perhaps in a few months, these materials will be in place.

The material problem seems to be solved, but Yi Chunhua and the others are still facing the problem of machining accuracy.

Before the materials were in place for the time being, Yi Chunhua and the others found some substitute materials for the time being and tried to process them, just as a practice.

Because parts processed from alternative materials can only be used for experimental purposes, they cannot be used as official parts of this aero-engine, let alone installed.

It’s just a matter of practicing, accumulating relevant processing experience, and smoothing the technological process. After the formal materials are purchased from overseas, with these processing experiences, the processing of formal parts will be much smoother.

But in the process of practicing, Yi Chunhua discovered a problem.

The processing accuracy of some key parts cannot meet the requirements, the main reason is the problem of processing equipment.The process technical information provided by the system specifies the recommended model of processing equipment, as well as the accuracy requirements of the equipment and so on.

But Yi Chunhua and the others did not have CNC equipment with the same level of precision, so problems arose.

For example, a certain turbine blade requires single-crystal superalloy materials. At present, single-crystal superalloys cannot be smelted in China. Yi Chunhua and the others use ordinary superalloy materials to temporarily replace them. After the blades are forged, they need to be processed on a high-precision five-axis machining center. Machining of the blade profile.

The blade profile is very complex, and the precision requirements are also very high.Once the accuracy requirements cannot be met, the performance and quality of the engine will be affected, because the turbine blade is one of the most critical parts in the entire engine.

Yi Chunhua and the others have several CNC five-axis machining centers, all of which are manufactured by the North Hehai Machine Tool Group. They belong to the world's quasi-first-class CNC five-axis machining centers. Such a machining center may have no problem processing other precision parts. .

But this is processing high-precision parts of aero-engines, or such advanced aero-engines, they cannot meet the precision requirements.Even during the Spring Festival, Yi Chunhua and others were still making various attempts and efforts, but all failed, and they still could not meet the machining accuracy requirements.

In fact, it's not just the turbine blades, such as turbine discs, fan blades, etc. These key parts also face such problems, so Yi Chunhua felt unprecedented pressure.

Accuracy can not reach ah!

This is a fatal problem.

Yi Chunhua's hair seemed to be quite grey.As the top leader, Yu Shaoguang also saw it in his eyes and was anxious in his heart.On the first day of work during the Spring Festival, he personally presided over the office meeting, and mainly discussed this issue.

At the meeting just now, someone suggested to seek domestic resources, find out which company has a high-precision five-axis linkage CNC machine tool, and seek their help. The finishing process of such parts is processed by such an enterprise.

But looking at the country, there are no high-precision five-axis linkage CNC machine tools. Even if there are, they are rare, and they are baby bumps. It is still unknown whether they can help you with parts processing.

Yu Shaoguang is going to take Yi Chunhua with him, and he will go to the capital tomorrow to report to the military and seek help from the military.

No idea!

This is a project with a military mission statement, and it is also a key project approved by the military. The engine needed for the first drone must be trial-produced within two years. Now, three months have passed, and this can no longer be done waited.

In addition, taking advantage of going to the military this time, Yu Shaoguang is also going to ask if the metal materials needed for this engine are available and when they will arrive.

China's material industry is still a little too weak, which restricts the development of aero-engine technology a little bit.An engine like this one, which is basically the pinnacle of medium and small turbofan engines, requires several high-tech materials, including single crystal superalloys, powder metallurgy superalloys, and a titanium alloy material.

These materials can only rely on imports, and the military will get them back from abroad through some channels and resources, and then hand them over to Yu Shaoguang's factory for the production of parts for this engine.

They are going to Beijing tomorrow.

.......
Deep Sea City.

The entire Jiuzhou Industrial Group has been at work for two days. During the two days just after the festival, Tang Fei mainly stayed in the Shenhai International Financial Building. Today was the first time he went out.

The first JF200A EMU entered the railway line for trial operation last year. It has run tens of thousands of kilometers, and it has been about two months. Detailed records of technical personnel of the train company.

This EMU has a record of 280 kilometers per hour at the highest speed. This speed is very gratifying, much faster than ordinary trains.

Tang Fei also knew about some situations.If it is known that it is undergoing trial operation on the Beijing-Changjiang Line of the north-south artery, it will go north to Beijing, south to Changzhou City, and will pass through Qingjiang City on the way.

Tang Fei took Li Xueyan, and Xu Guangming drove to Changzhou North Railway Station, because this EMU will arrive at its southbound terminal this morning, which is Changzhou North Railway Station.

After arriving here, we will stop at Changzhou North Railway Station for a day and start heading north tomorrow morning.On the Beijing-Changjiang Railway, it will also run a test run of hundreds of thousands of kilometers, conduct detailed tests and test runs, collect a large amount of transportation data, and conduct a comprehensive test and test on the comprehensive performance of the JF200A EMU, including its safety. test.

Xu Guangming drove smoothly and quickly.

Tang Fei and Li Xueyan sat in the back of the car and headed for Changzhou North Railway Station.Li Xueyan even asked: "Brother Fei, when will our EMU arrive at Changzhou North Station?"

Tang Fei raised his hand and looked at the time, "Well, there are still more than 40 minutes. It arrived at Changzhou North Railway Station at 52:[-] in the morning. After we arrived at the train station, it probably won't be long. It should come."

"Brother Fei, I want to take a good look at this train from a close distance."

Tang Fei smiled and said: "No problem, we can still board this EMU and go inside to have a look."

Tang Fei went there in person, not just boarding the train. On the one hand, he wanted to express condolences to the technicians accompanying the train, and on the other hand, he asked these technicians about the operation of the EMU.

Li Xueyan was very happy to hear that she could still board the train for a visit. This far exceeded her expectations. She originally thought that it would be great if she could walk to the side of the EMU and watch it up close.

You can actually board the car to visit!
Tang Fei smiled a little smugly, that expression seemed to say, don't even look at who I am, we made this EMU, boarding the car for a visit, it's a piece of cake.

The two were chatting happily in the car, and Xu Guangming concentrated on driving.

"Boss, Changzhou North Railway Station is ahead."

Tang Fei nodded lightly, thinking in his heart, he won't have to wait long to see this beautiful EMU again.

Xu Guangming drove and arrived at the train station. He found a place to park the car in the parking area of ​​the square outside the train station. Everyone was about to get off when Tang Fei's phone rang.

This is Zhang Ping calling from the capital.

Today is the third update, and the second update will be delivered!
