Chapter 621 Production Capacity: 400 units

Previous page        Return to Catalog        Next page

    In Project 10, Ascendas Group is mainly responsible for the manufacturing of fuselage segments 16, 17, and 18, as well as the supporting supplier of vertical tail rudder surfaces, ventral fins, and emergency ground power auxiliary units (GPUs).

    Don¡¯t underestimate these three fuselage parts, they are the most critical waist parts in Project 10.

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

    Project No. 10 is responsible for the development of domestic third-generation fighter jets. The technology is much improved compared to the second-generation fighter jets. The entire aircraft uses statically unstable technology, which requires the aircraft to use a fly-by-wire control system to lift the aircraft.  In addition to improving the driving performance, 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 segments undertaken by Ascendas Group are the key segments for wing-body fusion. Therefore, these three segments require not only super strong load-bearing structures, but also internal frames and external skins.  Because of aerodynamic needs, special-shaped curved surface extension must be made.

    This requires that the traditional riveting process is no longer applicable in some parts, and high-precision welding processes must be used to meet the requirements.

    After several searches across the country, only Tengfei Group could undertake the processing capabilities of electron beam welding for large 7-meter-long segmented parts. Coupled with Tengfei Group's profound knowledge in chemical milling, the No. 10 project team finally completed these three sections.  The most important fuselage body is produced by Ascendas Group.

    For Ascendas Group, it is indeed stressful to undertake the production of important fuselage segments of Project 10. After all, it is an important component of the third-generation fighter jet. Ascendas Group has never seen it before, let alone touched it.

    But to be honest, I am worried and overwhelmed, but that is not the case. After all, the 16th, 17th, and 18th fuselage sections of Project 10 can actually be regarded as the central wing box of the domestic third-generation fighter jet.  Segmentation.

    The Ascendas Group has never built a fighter jet, but the Ascendas Group is very familiar with the central wing box. Not to mention that other TM-9 aircraft can be mass-produced, the most important thing is that the Ascendas Group has made a breakthrough in the production process of the central wing box.

    Of course, the central wing box of the TM-9 aircraft is still a bit small. After all, it is only a small aircraft with a take-off weight of less than 5 tons. Even if the central wing box is there, it will be just like that.

    What truly reflects Ascendas Group¡¯s achievements in this area is the central wing box on the advanced light transport aircraft that is undergoing static testing. It is 6.4 meters long, 3.2 meters wide and 1.1 meters high.

    It is by cracking this hard nut that Ascendas Group can provide the advanced light transport aircraft with greater flexibility in the design and selection of airfoils, engines, and fuselages, so as to create many sub-models that will be derived in the future, thereby creating a civilian  Lay a solid foundation with common military platforms.

    Because of this, it is not difficult for Ascendas Group to produce three fuselage segments with central wing boxes for Project 10.

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

    ¡°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 that no matter what advanced processing methods foreign countries have in this regard, our nb of Tengfei Group  ¡ªThe Model 711 electrochemical hole machining equipment will not be inferior to them.

    Because our turbine blades use this process, the yield rate has increased from 32.4% to the current 85.7%, and the performance is surprisingly good. Otherwise, it would be impossible to increase the temperature in front of the turbine from the previous 986 degrees Celsius to 1228 degrees Celsius.  ¡­¡±

    Liu Chun's words became stronger and stronger the more he spoke, and the fat on his fat face was shaking. It seemed that the excitement that had been accumulated for a long time was about to explode at this moment. The surrounding chiefs and leaders were also attracted by Liu Chun's passionate words.  Infected, he nodded frequently in surprise and relief.

    Being able to overtake in corners and keep pace with the world's advanced level has been the dream of every Chinese for more than a hundred years. 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 as soon as possible.  Adding a more solid backbone to national defense modernization.

    In the past, although they had firm beliefs, they felt that it would take 20 to 30 years to achieve some results in the face of the huge technological gap abroad. However, when they saw Ascendas Group using nb-711 electrochemical hole processing equipment to overtake in corners,  I immediately felt that China was not as weak in high-end technology as imagined. As long as we were willing to work hard, we could not only catch up, but also surpass it.

    Of course there are those who are excited, and there are those who are calm-minded. Anyway, they just looked through the glass door and listened to Liu Chun say a lot of things emotionally, but it was reallyBut I didn't see any genuine products, so I waited for Liu Chun to pause and prepared to ask about this issue.

    But before these people could speak, a beeping sound suddenly sounded inside the glass door. Immediately, everyone saw a small rail-carrying truck loaded with packaged turbine blades slowly start from the factory and run to the glass door.  When opening the door, an iron gate at the back fell, and then the glass door opened.

    The small rail truck flashed its orange indicator light and drove forward smoothly and quickly along the track in the passage under the curious and astonished eyes of everyone.

    "automatic?"

    "Where are we going?"

    "Are you going to the workshop we just visited?"

    ¡­¡­

    Seeing such an automated transportation method, the leaders and chiefs present were all wide-eyed. The transportation method is automated. This scene is either uncommon or not seen in other factories.

    Even the calm-faced head of the headquarters had a slightly strange look on his face when he saw this.

    ¡°This is our group¡¯s automated rail transportation system. Around the No. 0 assembly workshop, the four surrounding subsidiary workshops and supporting factories are all connected to each other using similar rails, and this unmanned rail car is used to transport materials in the workshop.  and transportation of finished products, which greatly improves our production efficiency.¡±

    Liu Chun smiled and introduced the automatic rail transport vehicle that just drove past.

    "Is it similar to the way a railway operates?" asked a military leader.

    Liu Chun nodded: "Yes, we learned from the operation methods of the railway department and used computers to uniformly schedule transportation vehicles. This is how we have the current transportation system."

    "Then how many times a day can you make these automatic rail trucks go to workshop No. 0?" This question was not the previous unit leader, but the one who questioned Tengfei Aviation Power's lack of air film cooling hole processing equipment behind the crowd.  The chief of the Air Force, I don't know when, he and others had crowded in front of Liu Chun.

    Liu Chun didn¡¯t care, he chuckled: ¡°About 400 trains a day?¡±

    The head of the Air Force who asked the question was stunned for a moment, and quickly continued to ask: "Then what is the annual output of your wd-30s turbofan engine?"

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

    "400 unitsis stillnot much?"

    The head of the Air Force's eyes suddenly widened, his voice trembled and raised an octave, and his whole body swayed before he staggered and fell.
