Chapter 620 Supporting Project No. 10

Previous page        Return to Catalog        Next page

    No wonder Liu Chunhui said so confidently, nb-711 electrochemical hole processing equipment is a rare key technology equipment independently developed by Tengfei Group in recent years.

    Its origin is that H Company acquired unsystematic technical data from Japan, which was used to offset the cost of transferring UAV technology to H Company from Tengfei Factory.

    "It's just that the materials at that time were messy and unsystematic. Most of them were forward-looking delusions. The remaining few parts could not be applied immediately and required continued investment to achieve results.

    To put it bluntly, they are just useless pieces of chicken ribs.

    However, these are useless, Zhuang Jianye still carefully selected and selected, and finally found two key research directions. One is titanium aluminum alloy in terms of materials; the other is electrochemical precision for processing of film cooling holes in turbine blades.  Hole processing equipment.

    Because titanium-aluminum alloys are materials, they involve a lot of basic science. Although good progress has been made in recent years, they are still some way away from full application. However, with the deepening of the development of titanium-aluminum alloys, their unique properties have gradually gained recognition in aviation.  Industry recognition.

    Therefore, when applying for national key scientific research projects of the "Eighth Five-Year Plan" launched in 1989, the aerospace ministry, which was just established less than a year ago, applied for titanium-aluminum alloy as the ministry's key material research project for the next ten years, preparing to use "  The two five-year plans of the Eighth Five-Year Plan and the Ninth Five-Year Plan have developed this key new material that is related to the performance improvement of future aero-engines.

    Compared with the long cycle of titanium-aluminum alloy, the nb-711 electrochemical hole processing equipment is much smoother. As a key equipment research project of the "Seventh Five-Year Plan", Tengfei Group spent a full five years and finally put it into use.  This revolutionary processing equipment for film cooling holes in turbine blades is available.

    This is really important to Ascendas Group.

    You must know that the performance of the previous wd series aero engines or aeroderivative gas turbines is not much different from similar foreign products, especially when a large number of composite materials are used, the service life can completely compete with foreign products.

    But does this mean that the aero engines produced by Ascendas Group can compete with first-class foreign brands?

    The answer is very frustrating, that is, two words, no.

    As for why, the reason is very simple. The cost of aero engines or gas turbines produced by Ascendas Group is much higher than that of foreign brands.

    Didn¡¯t I say that Ascendas Group¡¯s cost control is top-notch in the country?

    It depends on what it is. In areas where Ascendas Group is confident, it is natural to control costs. However, if it is an area where it cannot grasp the direction of technology, it will not have the ability to control it even if it wants to.

    The turbine blades of aircraft engines are one of them.

    Because of the genetic attributes of Ascendas Group, it has the ability to crush composite materials, high-end aerospace equipment, small aircraft and even high-end medical equipment.

    But in terms of metal materials and metallurgy, he is completely weak, so he is a super partial student.

    And the aero engine turbine blades are made of genuine metal alloy materials. No matter how hard the Ascendas Group goes, after completing the processing of the film cooling holes, post-processing must be done, otherwise it will really be unsightly.  Will the engine life be reduced and scrapped in advance?

    The problem is that Ascendas Group cannot do this at all, so it can only choose to outsource it to other aerospace plants and strictly control quality on its own.

    " If it were placed in the United States or Europe, it would be okay for Ascendas Group to do this. Leaving professional matters to professional companies can not only promote the development of companies in this field, but also reduce its own costs.

    But there is a premise for all this, that is, the contracting company has very obvious technical advantages.

    European and American companies have accumulated experience for so many years, so it is not a problem, but domestic companies do not have this advantage, which results in a very high scrap rate.

    You must know that it is a turbine blade. The value of the material alone is ridiculously high. Coupled with a series of processing, the cost is frightening. If it were replaced by other companies, this is a minor problem that is innocuous. After all, the cost of losing one  It really hurts.

    However, Tengfei Group was unwilling to do so. Under Zhuang Jianye's request, it was almost willing to kill the wrong ones rather than let them go. If a batch of commissioned blades failed to pass, then all the products in this batch would not be remanufactured.  cast.

    The consequence of this is a sharp increase in costs, but it also ensures the quality of the aero engines produced by Ascendas Group.

    Of course, this approach will inevitably be criticized by some brother factories. There is no way, it is not only Ascendas Group that suffers losses due to strict quality control, but also other contracting factories.Because of this, the aviation industry has recognized over the years that Ascendas Group¡¯s work is not easy to do. In the words of a retired leader of a large manufacturer: ¡°Ascendas Group has nothing to say about its money, but it is just picky in production.  Four, it¡¯s very annoying.¡±

    It stands to reason that those brother factories that have the support of ministries and commissions to guarantee minimum production capacity will be too lazy to deal with them if they are driven crazy by Ascendas Group a few times. Anyway, their wages are only that much, and their income is guaranteed in droughts and floods. Why do they do it for those two stinky guys from Ascendas Group?  You are as humble as a grandson. They are all companies under the ministries and commissions. Do you have the qualifications?  What can you do to me if I quit?

    "Tengfei Group is really recruiting. After all, it is a rising star. In terms of seniority, it has to be called "senior" to those brother factories. What can Ascendas Group do?

    " However, Ascendas Group cannot do this. The No. 10 project that has been advancing has many tricks.

    Other companies and units have criticized Tengfei Group's practices, but the Project 10 project team saw new ideas for quality control of the entire Project 10 from Tengfei Group's changing quality requirements for outsourced components. Not only did the chief engineer personally  Come here to understand the operation of the entire quality system, and apply it to the supporting tasks of various subsystems of Project No. 10.

    You know, after several years of painstaking research, Project No. 10 has begun the trial production and verification of some systems. The project team of Project No. 10 was not sure how to control the production quality before. But now it is good. Ascendas Group has done a good job.  Demonstration, using its own strict control, it is hard to make the quality of the aero engines produced comparable to similar products in Western developed countries.

    Since high-end products such as aero engines can require this level of development, Project 10, a third-generation fighter jet, can also be achieved.

    As a result, the Project 10 project team completely broke away from the organizational model of supporting production plants designated by ministries and commissions in the past. Instead, it sent people to conduct factory-by-factory surveys and study product performance data by data, and then used a method similar to bidding to meet the requirements.  Enterprises that meet the requirements are selected and a complete reward and punishment withdrawal mechanism and a competition mechanism between products are established, forcing those supporting manufacturers to continuously improve the performance of accessories and strengthen quality awareness.

    With the bulldozer of Project No. 10 rumbling forward, Ascendas Group did not have to work so hard and thanklessly in front. By supporting Project No. 10, it finally managed to trick two aircraft production plants and tortured them until nb  ¡ªThe 711 type electrochemical hole processing equipment was successfully put into production.

    Of course, even if the two aerospace plants supporting Ascendas Group knew that they were being deceived, they would do so willingly. They had no choice but to do so. In fact, Ascendas Group plays a crucial role in the entire No. 10 Project, because in addition to the designated successful aircraft manufacturing company,  Apart from the main contracting enterprises, Ascendas Group has the most supporting projects, accounting for 28.6% of the total machine manufacturing.
