Chapter 620

It's not surprising that Liu Chunhui said that the nb-711 electrochemical hole processing equipment is a key technology equipment rarely developed by Tengfei group in recent years.

It originated from the unsystematic technical data that H company collected from Japan in those years, which was used to offset the transfer cost of UAV technology from Tengfei factory to H company.

However, the materials at that time were disorderly and unsystematic. Most of them were forward-looking delusions, and the remaining few could not be applied immediately. They needed to continue to invest in order to achieve results.

To put it bluntly, it's just chicken ribs that don't work.

However, it is these chicken ribs that Zhuang Jianye carefully chose and chose, and finally found two key directions for tackling key problems, one is the titanium aluminum alloy in the aspect of materials, and the other is the electrochemical precision hole processing equipment for the machining of turbine blade film cooling holes.

Because titanium aluminum alloy is a kind of material, it involves a lot of basic science. Although it has made good progress in recent years, it is still a long way from its full application. However, with the development of titanium aluminum alloy, its unique properties are gradually recognized by the aviation industry.

Therefore, when the Ministry of Aeronautics and Astronautics applied for the national key scientific research project of the eighth five year plan, which was launched in 1989, the Ministry of Aeronautics and Astronautics, which has just been established for less than a year, declared titanium aluminum alloy as the key material scientific research project of the Ministry in the next ten years, and prepared to use the two five-year plans of the eighth five year plan and the ninth five year plan to develop this key new material which is related to the leap of aeroengine performance in the future It's developed for you.

Compared with the long cycle of titanium aluminum alloy, nb-711 electrochemical hole processing equipment is much smoother. As the key equipment project of the Seventh Five Year Plan, Tengfei group has spent five years, and finally won this subversive processing equipment of turbine blade film cooling hole.

This is too important for Tengfei group.

It is necessary to know that although the performance of WD series aeroengine or gas turbine converted from aviation is similar to that of foreign similar products, especially in the application of a large number of composite materials, the service life of WD series aeroengine or gas turbine can be compared with that of foreign products.

But does this mean that the aeroengine produced by Tengfei group can compete with foreign first-class brands?

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

As for why, the reason is very simple. The cost of aeroengine or gas turbine produced by Tengfei group is much higher than that of foreign brands.

Is it not that the cost control of Tengfei group is first-class in China?

It also depends on what it is. The cost of Tengfei group naturally needs to be controlled in certain areas. However, if it is unable to grasp the direction of technology, it will not be able to control it even if it wants to.

Turbine blade of aeroengine is one of them.

Because of the genetic properties of Tengfei group, it can be used in composite materials, aerospace special high-end equipment, small aircraft and even high-end medical equipment.

Can be in metal materials and metallurgy on the weak mess, the appropriate super partial science students.

And the turbine blade of aero-engine is made of metal alloy material, even if Tengfei group is against the weather, after finishing the processing of film cooling hole, the post-processing always has to be done, otherwise it will really see the engine life reduced and scrapped ahead of time?

The problem is that Tengfei group can't do it at all. It can only choose to outsource it to other aircraft manufacturers and strictly control the quality on its own side.

If it is placed in the United States or Europe, it is nothing for Tengfei group to operate in this way. Leaving professional affairs to professional enterprises can not only promote the development of enterprises in this field, but also reduce their own costs.

But all this has a premise, that is, the technical advantage of the contracting enterprise is very obvious.

European and American enterprises have accumulated for so many years, so it is not a problem. However, domestic enterprises have no advantage in this respect. As a result, the waste rate is very high.

You know, it's a turbine blade. The value of the material alone is outrageous. In addition, a series of processing costs are frightening. If it's replaced by other enterprises, the minor problems that are harmless will be put away. After all, the cost of losing one is really painful.

However, at the request of Zhuang Jianye, Tengfei group would rather kill the wrong blade than let it go. If a batch of blades are not qualified, then all the products in this batch should not be recast.

As a result, the cost rises sharply, but the quality of the aeroengine produced by Tengfei group is guaranteed.

Of course, this practice is also inevitably criticized by some brother factories, there is no way, strict quality control, the loss is not only Tengfei group, other contractors are the same.

Because of this, in recent years, the aviation industry has recognized that the work of the Tengfei group is not easy to do. In the words of a retired leader of a large factory, it is: "the money of the Tengfei group is not worth mentioning, but it is very annoying to be picky in production."

According to the truth, those brother factories with the support of the Ministry's minimum production capacity will be too lazy to deal with if they are maddened by Tengfei group several times. Anyway, their wages are so much, and they are guaranteed by drought and flood. Why do you want the two stinky money of Tengfei group to be inferior to a grandson? They are all enterprises under the Ministry. Do you have the qualification? What can you do to me when I quit.Tengfei group is a real recruit. After all, it's a rising star. When it comes to seniority, we have to call those brother factories a senior. What can Tengfei group do?

However, Tengfei group can't do this. There are plenty of moves for the No. 10 project.

Other enterprises and units denounce the practice of Tengfei group, but the project team of No. 10 project has seen the new idea of quality control of the whole No. 10 project from the quality requirements of Tengfei group for outsourcing parts. Not only the chief engineer came to understand the operation of the whole quality system, but also applied it to the supporting tasks of various subsystems of No. 10 project.

You know, after years of painstaking research, part of the system of project 10 has been trial produced and verified. The project team of project 10 had no idea how to control the production quality before. Now, Tengfei group has made a good demonstration. With its strict control, the quality of the aero-engine produced by Tengfei group is not as good as that of similar products in western developed countries Up and down.

Since high-end products such as aeroengines can be required to this extent, the 10th project, as a third-generation fighter, can also be realized.

Therefore, the project team of No.10 project completely got rid of the previous organizational mode of the ministries and commissions designating supporting production plants. Instead, it sent people to find out each plant, and made a thorough investigation of each data of product performance. Then, it used a similar way of bidding to select the enterprises that met the requirements, and established a perfect reward and punishment exit mechanism and a competition mechanism among products to force those matching enterprises The factory continuously improves the performance of accessories and strengthens the quality awareness.

With project 10, the bulldozer boomed forward, so Tengfei group didn't have to work so hard to get ahead. With the supporting project 10, it finally fooled two aeroengine production plants, until nb-711 electrochemical hole processing equipment was put into production smoothly.

Of course, even if the two air development plants supporting Tengfei group know that they have been cheated, they are willing to do so. In fact, Tengfei group plays an important role in the 10th project, because in addition to the designated successful aircraft manufacturing company, which is the main contractor, Tengfei group has the most supporting projects, reaching 28.6% of the total machine manufacturing
