Ascendas Group is mainly responsible for the manufacturing of the 16th, 17th, and 18th fuselage sections in the 10th project, the supporting supplier of the vertical tail rudder surface, pelvic fins and emergency ground power assist device (GPU).

Don't underestimate these three body sections, they are the most critical part of the waist of the No.10 project.

On the second-generation machine, although this part is important, the focus is only on a single structural load bearing, and the manufacturing requirements are relatively simple.

The No. 10 project undertakes the research and development project of the domestic third-generation fighter, which is technically improved compared to the second-generation fighter. The whole aircraft adopts static instability technology, which makes the aircraft must use the fly-by-wire control system to lift the aircraft. In addition to the driving performance of the aircraft, the aerodynamic layout of the aircraft must also be significantly improved.

One of them is the use of wing-body fusion technology.

The 16th, 17th, and 18th fuselage sections undertaken by Ascendas Group are the key sections for wing body fusion. Therefore, in these three sections, not only super strong bearing structure, internal frame and external skin are required. Because of the need of aerodynamics, special-shaped curved surfaces must be extended.

This requires that the traditional riveting process is no longer applicable in some parts, and high-precision welding processes must be used to meet the requirements.

Throughout the country, only Ascendas Group can undertake the processing capacity of electron beam welding of large-scale segmented parts with a length of 7 meters. Coupled with Ascendas Group’s profound knowledge in chemical milling, the No. 10 engineering project team finally combined these three sections. The most important fuselage body is delivered to Ascendas Group.

As far as Ascendas Group is concerned, the production of the important airframe segment for the No. 10 project is indeed under pressure. After all, it is an important part of the third-generation fighter. Ascendas Group has never seen it before, let alone touch it.

But if you are really worried about what to do, it is not enough. After all, the 16th, 17th, and 18th fuselage sections of the No. 10 project can actually be regarded as the central wing box of the third-generation domestic fighter. Segmented.

The fighter Ascendas Group has never built it, but the Central Wing Box Ascendas Group is very familiar with it. Not to mention that other TM-9 aircraft can be mass-produced. The most important thing is that the Ascendas Group has broken through the production technology of the Central Wing Box.

Of course, the central wing box of the TM-9 aircraft is still a bit smaller. After all, it is only a small aircraft with a takeoff weight of less than 5 tons, even if the central wing box is in the same state.

What truly embodies Ascendas Group's accomplishments in this regard is the central wing box on the advanced light transport aircraft undergoing static tests, with a total length of 6.4 meters, a width of 3.2 meters and a height of 1.1 meters.

It is precisely this difficult bone that Ascendas Group has gnawed down to allow advanced light transport aircraft to have greater flexibility in the design and selection of wings, engines, and fuselages, which will be derived from many sub-models in the future to create civilian use. Lay a solid foundation with the military general platform.

Because of this, it is not difficult for Ascendas Group to produce three fuselage sections with a central wing box for the No. 10 project.

Of course, there are not many people who know about these important matters except for the head of the headquarters and other core leaders, but even those who know the important production work undertaken by Ascendas Group are attracted by Liu Chun’s confident words at this moment. Past.

"I don't know if other countries in the world have applied other integrated turbine blade film cooling hole processing technology, but I dare to say responsibly, no matter what advanced processing methods foreign countries have in this regard, our Ascendas Group's NB -711 type electrochemical hole processing equipment will not be worse by them.

Because our turbine blades are using this process, the yield rate has increased from 32.4% to the current 85.7%, and the performance is surprisingly good. Otherwise, it is impossible to increase the temperature before the turbine from the previous 986 degrees Celsius to 1228 degrees Celsius. ..."

Liu Chun’s words became stronger as he spoke, and his fat face was trembling with fat, and it seemed that the excitement that had been accumulated for a long time was about to explode at this moment. The surrounding leaders and leaders were also affected by Liu Chun’s passionate words. Infection, in addition to surprise, he nodded frequently in relief.

It has been a dream of every Chinese for more than a hundred years to be able to overtake a car in a corner and keep pace with the world's advanced level. Especially these leading cadres in the army, are looking forward to the domestic industry to work hard and catch up with the world's advanced level earlier. Add a more solid backbone to the modernization of national defense.

In the past, although they had a firm belief, they felt that it would take 20 to 30 years to achieve some results in the face of the huge technological gap abroad. But when they saw Ascendas Group use the NB-711 electrochemical hole processing equipment to overtake the car, I immediately felt that the domestic high-end technology is not as weak as imagined. As long as we work hard, we can not only catch up, but also surpass it.

Of course, if you are excited, you will naturally have a cool head. Anyway, they just looked through the glass door, and listened to Liu Chun emotionally talking a lot, but the real product was not seen. So I waited for Liu Chun to pause, and then prepared to ask about this question.

But before these people could speak, there was a beeping sound inside the glass door, and immediately everyone saw a small track truck loaded with encapsulated turbine blades slowly starting from the factory building and running to the glass. When the door was opened, an iron gate at the back fell, and then the glass door opened.

The mini-track truck flashed orange indicator lights, and drove forward smoothly and quickly under the curious and stunned eyes of everyone along the track in the passage.

"automatic?"

"Where is this going?"

"Is it going to the workshop we just visited?"

...

Seeing such an automated mode of transportation, all the leaders and chiefs present had their eyes widened, and the mode of transportation was actually automated. This scene is not uncommon in other factories, or there is no such thing.

Even the head of the headquarters with a calm complexion saw this with a slightly strange look on his face.

"This is our group's automated rail transportation system. Around the No. 0 assembly workshop, the surrounding four subordinate workshops and supporting workshops are connected with each other by similar tracks, and this unmanned rail car is used to carry materials in the workshop. And the transportation of finished products greatly improves our production efficiency."

Liu Chun smiled and introduced the automatic rail transport vehicle that had just passed by.

"Is it a railway-like operation?" a military leader asked.

Liu Chun nodded: "Yes~lightnovelpub.net~ We learned from the operation method of the railway department and used the computer to dispatch the transportation vehicles uniformly, and then we have the current transportation system."

"Then how many such automatic rail trucks can you go to workshop 0 in a day?" This question is not the previous leader of the army, but the previous questioning the lack of film cooling hole processing equipment for Ascendas Aerodynamics after the crowd. The head of the air force, I don't know when, he and others have already squeezed in front of Liu Chun.

Liu Chun didn't care, and he smiled: "About 400 trips a day?"

The head of the air force who asked the question was taken aback, and quickly continued to ask: "Then what is the annual output of your WD-30S turbofan engine?"

"Not many, there will be over 400 units." Liu Chun smiled brightly.

"400...not many...not many?"

The head of the air force suddenly opened his eyes, his voice trembled and raised an octave, his whole body shook, and no one stumbled.
