The head of the headquarters knows that Tengfei Group has a pulsating production line for aircraft, and in recent years, the domestic military and civil aviation have ordered two or three hundred Y-6 and Plateau Eagle series, and TM-9 aircraft can be quickly produced and delivered, and the pulsating production line has contributed a lot.

Because of this, the pulsating production line of Tengfei Group's aircraft assembly plant also caused a big sensation in the aviation industry, and soon formed two opinions for and against.

It goes without saying that the proponents feel that this pulsating production line improves production efficiency, accelerates the pace of production, and in a sense, can reduce product costs, representing the development direction of aviation product assembly in the future.

The reason of the opponents cannot be said to be insufficient, that is, the cost of the entire production line is too high, and such as control computers, advanced transmission systems, special vehicles, hydraulic lifting, and other special tools for key assembly need to be imported from abroad, and counting other miscellaneous expenses, the entire production line is enough to build three or four aircraft assembly plants of the same size.

What's more, the basis of Tengfei Group's aircraft pulsating production line is a self-developed high-precision laser positioning measurement system and a semi-automated flexible tooling processing system.

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

During the production of the Y-6, Plateau Eagle series and TM-9 aircraft, the aircraft assembly plant of Tengfei Group had to suspend production and overhaul several times due to the failure of these two systems.

Factories, especially aviation factories, are not ordinary people's big beds and small quilts, how to toss as you want, stop production and maintenance to say lightly, but behind it is a staggering amount of losses, not stones, really a real little money.

Other aerospace manufacturers, even if they know that Ascendas' pulsating production line is a good thing, are deterred when they learn that the failure rate is high, because no one wants to be in the process of smooth production, click, the equipment is broken, and all processes have to stop and wait for processing.

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

In addition, Ascendas Group is only a production plant for small aircraft of less than 5 tons, which makes people feel that the pulsating production line is limited to small aircraft, and large aircraft are more complex, and similar optimization and upgrading may not work.

As a result, the pulsating production line in the aircraft assembly plant of the Ascendas Group only made a slight splash, and soon it was calm as water.

When the head of the headquarters was just transferred to the headquarters, he had an understanding of this peculiar production method, and it has to be said that it is indeed very strong in terms of efficiency, but the maturity level still needs to be improved, which is the comment given by the head of the headquarters after understanding the pulsating production line of the aircraft of the Tengfei Group.

I thought that Tengfei Group would continue to research along the pulsating production line of aircraft and improve its maturity, but I did not expect that they would start a pulsating production line for turbofan engines.

Aero engines can also be used to assemble aircraft?

The head of the headquarters listened to Zhuang Jianye's words with doubts on his face, you must know that the failure rate of the pulsating production line of the aircraft is not low, and if the set is taken to the turbofan engine, the loss will be much greater than that of the aircraft production line.

You must know that the parts on the aviation engine are all precision parts, and they will be scrapped directly after being bumped, unlike airplanes, which are very solid in some places, even if they are broken, they can continue to be used with a piece of skin.

So looking at Zhuang Jianye's eyes a little worried, Zhuang Jianye didn't understand the idea of the head of the headquarters, pointed to the production in front and said: "Rest assured, our high-precision laser measurement system and flexible tooling system have been developed to the second generation, and the failure rate has been compressed to 6%, although it is still high, but it is within the range of bearing." ”

Zhuang Jianye is right, compared with the 16.5% failure rate of the first-generation high-precision laser measurement system and flexible tooling system in the No. 2 aircraft assembly workshop of Tengfei Group, 6% is indeed a lot higher.

It could have been improved more, but unfortunately some precision components that need to be imported cannot be obtained for various reasons, and can only be made up for by alternatives, resulting in the control range of the failure rate not reaching the theoretical index of less than 2%.

However, thanks to the basic design of the high-precision laser measurement system and flexible tooling system, which is independently developed by Tengfei Group, it has a very high elastic redundancy, which makes the alternative have room to show.

That's the benefit of mastering core technology.

Therefore, the failure rate of 6% is a few percentage points higher than that of the general aviation development plant, but if the annual output of 400 units is counted, the efficiency of the order of 600 units can be completed in about a year and a half, and the failure rate can still be bearable.

The head of the headquarters didn't speak, just nodded, but the worry in the eyes on the bags was significantly reduced, and he looked at the leaders and leaders who were like curious babies who were watching the assembly of turbofan engines, and the corners of his mouth pulled out a knowing smile, and then he raised his chin and slowly spoke: "There are a few military representatives in the early years of the aviation development plant, and they are very familiar with the aviation development plant. ”

After finishing speaking, he turned his head, and the words changed abruptly: "By the way, how is the processing technology of the fuel tank of a new type of missile?"

Zhuang Jianye's thinking was still in the context of the previous words of the head of the headquarters, with a simple and smug smile, but he didn't want to turn to other aspects the next moment, his head didn't turn for a while, and he was stunned for a moment, only to find that there was no one around the head of the headquarters except for the two heads of the Second Artillery Corps, so he said with a solemn expression: "We are still stepping up our efforts to tackle key problems, if nothing else, there will be preliminary results next year." ”

"You still have a good set of new process research and development and application, and you need to maintain this advantage. ”

The head of the headquarters bowed slightly, and the head of the headquarters was actually more concerned about the situation of a new type of missile, and the progress of each subsystem had to be 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 missile are higher, so in the first stage of the system test, the fuel storage tank processed by traditional means did not pass the review of the project chief engineer and was sent back for reprocessing.

At this moment, Peng Chuan, Zhou Lei, Liang Mu, Wei Guangping, Xie Dong and other aerospace special equipment research and development teams are all concentrated in the zero degree factory, and are focusing on related aspects of research, and good progress has been made.

Although the head of the General Headquarters is well aware of the progress of the situation, he still wants to hear a responsible statement from the person in charge of the specific task, and there is no way, let alone the fact that the head of the General Headquarters is breezy every day, in fact, he is more nervous than anyone else in terms of a certain new type of missile.

Hearing the good news, the smile of the head of the headquarters became slightly easier, and he raised his chin at the production line in front of him again, and once again threw out a very sensitive question: "This is your weight to open up the international aviation market?"

"Chief, are you laughing at me?" Zhuang Jianye asked rhetorically, the head of the headquarters was stunned, turned his head to look at Zhuang Jianye, and Zhuang Jianye smiled: "Kill chickens with a knife!"

When the head of the headquarters heard this, he blinked his eyes and immediately laughed.
