Chapter 824 Low-cost flexible manufacturing

Previous page        Return to Catalog        Next page

    Some people may think that the output of 18.2 tons of aviation fuel is not much. At best, it can refuel 6 J-82s or 3 Su-27s.

    But this value has already made quite a few people in the Air Force very satisfied.

    You must know that the H-6 aviation fuel carrying capacity reaches 37 tons, but the amount it can output is only 18.5 tons, and the range is only about 5,500 kilometers, and the combat radius is only slightly more than the 1,500 kilometers of the Su-27.  1800 kilometers.

    This indicator is no longer a shortcoming for a special aircraft designed to provide air support and logistics support for combat aircraft, but almost becomes a burden.

    On the other hand, the Tanker-15, which was developed on the basis of the Yun-15max, has a maximum fully loaded range of 7,200 kilometers and a combat radius of 3,000 kilometers, which can fully meet the development needs of the Air Force in the next ten years.

    After all, the Air Force is actively expanding the scale of the Su-27 series of heavy-duty fighter jets. Coupled with the J-10 fighter jet, which is about to complete development and prepare to enter the intensive test flight stage, the number of domestic third-generation fighter jets will usher in explosive growth in the future.

    Under such circumstances, it is obviously difficult for a tanker with a combat radius that is only slightly larger than that of a fighter jet to meet the actual needs of the future air force's integrated offensive and defensive capabilities.

    What¡¯s more, the YY-15 also has an advantage over the H-6 in terms of overall cost.

    Yes, even though the H-6 is an improved version of the mature H-6, after careful calculation, the overall comprehensive operating cost is much higher than that of the brand-new Y-15.

    Logically speaking, this situation should not occur. After all, the H-6 has been groping for nearly 30 years in the Northwest Aviation Factory starting from the imitation of the Tu-16 bomber in the 1960s. Not to mention that you can grind an iron pestle into a needle, but you should also grind things  To be honest, at least you should be familiar with all aspects.

    In fact, the Northwest Aviation Factory really has nothing to say in this regard. It is extremely familiar with every part of the H-6. Even many masters who touch the parts with their eyes closed can accurately tell the tolerances.  More or less, without him, he has been practicing this unique skill for most of his life.

    If this were not the case, the Air Force would not have focused on the H-6 in the first place, just to make this force multiplier that can punch farther be completely independent, so as not to be controlled by others at critical moments.

    As a result, when comparing the H-6 with the H-15, the Air Force was shocked from top to bottom. Regardless of whether the performance was good or bad, in terms of manufacturing cost, the brand-new H-15 was nearly half the cost of the mature H-6.  20%.

    You must know that Hongyou 6 uses a lot of the processing technology of Hongyou 6, and almost 60% of the parts on it are interchangeable; while Yunyou-15 is basically Yunyou-15plus, and the rest is almost brand new from the inside out.  Not only the upper and lower parts are widened and enlarged, but also the number of engines has been increased from two to four.

    It can be said that everything has been changed from the inside to the outside. It is a new model.

    It stands to reason that the purchase cost of Hongyou-6, which uses mature technology, should be lower than that of brand-new Yunyou-15. The result is exactly the opposite.

    The leaders of the Air Force were very puzzled, so they visited Ascendas Group and Northwest Aviation Factory. They didn¡¯t know it, but they were really shocked.

    I thought that the two aviation companies were about the same size, and their strength should be indistinguishable. However, after a closer look, I discovered that the concepts, technologies used, processes applied, and configurations adopted by the two companies were almost the same as those on the ground.

    The Northwest Aviation Factory's H-6 uses more than 60% of the H-6's mature technology and production processes, which indeed reduces costs. But the key to this cost reduction depends on who it compares with. Compared with traditional aviation factories, this is true, but with Tengfei Group  The comparison is not enough.

    Because 95% of the technology used by Tengfei Group to produce Yunyou-15 follows the production process of Yunyou-15.

    What does this mean?

    ??Tengfei Group can save 95% of the costs of fixtures, molds, tolerance measurements, etc. during the manufacturing process. It only needs to invest a certain amount of funds in the other 5% to solve all production problems.

    The Northwest Aviation Factory can only use 60% of the existing fixtures, molds, and tolerance measurement tools on the H-6 production line. The remaining 40% needs to be completely remade due to the uniqueness of the aerial tanker and its small size in the Air Force.  The inventory of many specific molds and fixtures is estimated to be eliminated and scrapped when this model is used up.

    It is precisely these things that account for a large amount of production costs in the production of Hongyou 6.

    On the other hand, Ascendas Group does not need to consider these at all. Although there are differences, Ascendas Group will try its best to apply these specific fixtures, molds, and tolerance measurement tools to the production and processing of other models, so that they can continue to shine.

    This is the aircraft flexible manufacturing technology that Ascendas Group has been researching since the mid-1980s and gradually applying it to aviation production.

    At the beginning, Ascendas Group applied thisAlthough the manufacturing technology caused a sensation in the industry, it was not widely imitated. The reason is that the one-time investment in this manufacturing technology is too large.

    Take the flexible fixtures commonly equipped in Ascendas Group¡¯s aircraft production lines as an example. This kind of fixture uses vacuum to absorb workpieces and can automatically adjust according to the shape of the parts. Just a small part fixture the size of a shoe box costs 200,000 yuan.

    And making a traditional tooling fixture may not even cost 30,000 yuan.

    With this comparison, other aviation manufacturers can only boast that Ascendas Group is indeed a pioneer in catching up with technological trends in China, and thenthenthere is nothing more.

    The aviation factories are not stupid. They spend 200,000 yuan to solve a problem that can be solved with 30,000 yuan.

    Therefore, in the mid-1980s, the products of other aviation manufacturers were still very competitive in terms of cost. After all, the technical costs of the Ascendas Group's production lines during that period were extremely high and could not be reduced at all. Therefore, the Ascendas Group at that time did not follow these standards.  The aviation factories are facing each other head-on, but they are looking for air strikes that are not covered by major aviation factories to conduct differentiated operations.

    For example, UAVs, Y-6 small transport aircraft, Y-15 series light transport aircraft, Y-16 special modified aircraft, TM-9 small business aircraft, etc.

    However, as time goes by, other aviation factories have made batch after batch of 30,000 yuan molds. Over the past few years, with the rise of materials and the fluctuation of currency exchange rates, the production cost has not only not dropped, but has increased over the past few years.  It has risen a lot before.

    The 200,000 yuan that Ascendas Group invested in that year has already been lower than the 30,000 yuan that other aviation factories spent to make molds after years of cost dilution.

    Under the circumstances, Tengfei Group's cost advantage immediately emerged. Coupled with years of continuous research on flexible processing and pulsating production lines, as well as consistent cost control, Tengfei Group is no longer Wu Xia Amon, but  Guan Yu was still the same Guan Yu back then.

    Zhuang Jianye rolled his eyes when he saw this, why did he not kill Jingzhou to seize the territory?
