Chapter 623

The head of the headquarters knows that Tengfei group has a pulsating production line for airplanes. Over the years, the domestic military and civil aviation have ordered two or three hundred yun-6 highland hawk series. Tm-9 airplanes can be produced and delivered quickly, and the pulsating production line has contributed a lot.

Because of this, the pulsating production line in the aircraft assembly plant of Tengfei group also caused a great sensation in the aviation industry, and soon formed two opinions of support and opposition.

It is self-evident that the supporters feel that this kind of pulsating production line improves the production efficiency, speeds up the production rhythm, and in a sense can reduce the product cost, which represents the development direction of aviation product assembly in the future.

The opponent's reason can not be said to be insufficient, that is, the cost of the whole production line is too high, and the control computer, advanced transmission system, special vehicles, hydraulic lifting and other key special tools for assembly need to be imported from abroad. In addition to other miscellaneous expenses, the whole production line can build three or four of the same scale We are now in the final assembly plant.

What's more, the foundation of the pulsating production line of Tengfei group is the self-developed high-precision laser positioning measurement system and semi-automatic flexible tooling processing system.

These two systems are disruptive technological innovations for aircraft assembly, but the problem is that these two systems are too advanced and immature in many places, resulting in high failure rate.

During the production of yun-6 highland hawk series and tm-9 aircraft, the aircraft assembly plant of Tengfei group had to suspend production several times for maintenance due to the failure of these two systems.

Factories, especially aviation factories, are not ordinary people's big beds and small quilts. They can toss about as much as they want. It's easy to stop production and maintenance, but it's a staggering amount of loss behind it. It's not stones that float in the water, it's real small money.

Other aviation manufacturers even know that the pulsating production line of Tengfei group is a good thing, but when they know that the failure rate is on the high side, they are also deterred, because no one wants to be in the process of production, the equipment breaks down, and all processes have to stop and wait for processing.

This disrupts not only the general process flow, but also the confidence and ability of the whole enterprise.

In addition, Tengfei group is only a manufacturer of small airplanes of less than 5 tons, which makes people feel that the pulsating production line is limited to small airplanes, and large airplanes are more complex, so similar optimization and upgrading may not work.

As a result, the pulsating production line in the aircraft assembly plant of Tengfei group just raised a little splash, and soon it was as calm as water.

When the head of the headquarters was just transferred to the headquarters, he knew about this strange production mode. He had to say that the efficiency was really strong, but the maturity still needed to be improved. This is the comment given by the head of the headquarters after understanding the pulsating production line of the Tengfei group.

I thought that Tengfei group would continue to research and improve its maturity along the pulsating production line of aircraft. Unexpectedly, they started a new pulsating production line of turbofan engine.

Can aeroengines be assembled in the same way as airplanes?

The head of the headquarters is full of doubts after listening to Zhuang Jianye's words. You should know that the failure rate of the pulsating production line of the aircraft is not low. If you take that set to the turbofan engine side, the loss will be much greater than that of the aircraft production line.

You should know that the parts on the aircraft are all precision parts. If they are knocked, they will be scrapped directly. Unlike the aircraft, which is very skinny in some places, even if it is broken, a new skin can still be used.

Looking at Zhuang Jianye, he was worried. He didn't understand the head of the headquarters. He pointed to the production in front of him and said, "don't worry, our high-precision laser measurement system and flexible tooling system have developed to the second generation, and the failure rate has been reduced to 6%. Although it is still on the high side, it is within the acceptable range."

What Zhuang Jianye said is right. Compared with the 16.5% failure rate of the first generation high-precision laser measurement system and flexible tooling system in the general assembly workshop of No.2 aircraft of Tengfei group, the 6% failure rate has increased a lot.

It was a pity that some of the precision components needed to be imported could not be obtained due to various reasons, so they could only be made up with alternative solutions. As a result, the control range of failure rate did not reach the theoretical target of less than 2%.

However, thanks to the fact that the basic design of high-precision laser measurement system and flexible tooling system is independently researched and developed by Tengfei group, which has extremely high elastic redundancy, the alternative scheme has room to display. Otherwise, it is a problem whether the second generation of high-precision laser measurement system and flexible tooling system can maintain the first generation of pulsating production line.

This is the advantage of mastering core technology.

Therefore, the failure rate of 6% is a few percentage points higher than that of the general aeroengine manufacturers. However, if we take into account the annual output of 400 units, we can complete the order of 600 units in about a year and a half. The failure rate is still affordable.

The head of the headquarters did not speak, but just nodded, but the color of worry in his eyes was obviously reduced. Looking at the leaders and heads who were watching the turbofan engine assembly like curious babies, they pulled out a knowing smile. Then they raised their chin to the front and spoke slowly: "there are several military representatives who worked in the aviation development factory in the early years, and they have a deep understanding of the aviation development I'm very familiar with them. Looking at their appearance, your pulsating production line is an eye opener for them. "Then he turned his head and said, "by the way, how is the fuel tank processing technology of a new missile doing?"

Zhuang Jianye's thinking still stays in the discourse context of the head of the headquarters, with a simple and complacent smile, but he doesn't want to turn to other aspects in the next moment. His head didn't turn around for a moment, and he was stunned for a moment. Then he found that there was no one beside the head of the headquarters except for the two heads of the second artillery. He said solemnly: "still stepping up the attack If there is no accident, there will be preliminary results next year. "

"You still have a set of advantages in the R & D and application of new technology, and you should keep the advantages in this respect."

The head of the headquarters nodded slightly. In the case of a new missile, the head of the headquarters is the most in charge. In fact, he is more concerned than anyone else, and the progress of each subsystem is reported to him every week.

The fuel storage tank manufacturing task undertaken by Tengfei group is the same, but compared with the traditional fuel storage tank, the requirements of a new type of missile are higher. Therefore, in the first phase of system experiment, the fuel storage tank processed by traditional means did not pass the review of the project chief engineer and was called back for reprocessing.

At this moment, the core of the R & D teams of aerospace special equipment, such as Pengchuan, Zhou Lei, Liang mu, Wei Guangping and Xie Dong, are all concentrated in the zero degree factory, and are carrying out concentrated research on relevant aspects, and have made good progress.

Although the head of the headquarters is clear about the progress, he still wants to hear the responsible statement from the person in charge of the specific task. He can't help it. Although the head of the headquarters is calm every day, he is actually more nervous than anyone in terms of a new type of missile.

After hearing the good news, the head of the headquarters began to smile a little more easily. He once again raised his chin to the production line in front of him and asked a very sensitive question: "is this the weight you need to get through the international aviation market?"

"Chief, are you laughing at me?" When Zhuang Jianye asked, the head of the headquarters was stunned. He looked at Zhuang Jianye and said with a smile, "why kill a chicken with a bull's knife?"

The head of the headquarters heard the speech, blinked his eyes, and immediately laughed.
