It is no wonder that Liu Chun will say that he is so confident, NB-711 electrochemical hole processing equipment is a rare independent research and development of key technical equipment of Tengfei Group in recent years.

Its origin was the unsystematic technical data that Company H obtained from Japan at that time, which was used to offset the transfer costs of Ascendas Factory to Company H in UAV technology.

It's just that the materials at that time were disorganized and unsystematic, and most of them were forward-looking delusions, and the few remaining parts could not be applied immediately, and they needed to be continuously invested to achieve results.

To put it bluntly, it's just some useless chicken ribs.

However, it is these chicken ribs, Zhuang Jianye still carefully chose and selected, and finally found two key directions, one is titanium aluminum alloy in terms of materials, and the other is electrochemical precision hole processing equipment used for turbine blade air film cooling hole processing.

Titanium aluminum alloy because it is a material, involving a lot of basic science, although good progress has been made in recent years, but there is still a distance from the complete application, but with the deepening of the development of titanium aluminum alloy, its unique performance has gradually been recognized by the aviation industry.

Therefore, in 1989, when the "Eighth Five-Year Plan" national key scientific research project was applied, the aerospace ministry, which had just been established for less than a year, declared titanium aluminum alloy as a key material scientific research project of the ministry in the next ten years, and was ready to use the "Eighth Five-Year Plan" and "Ninth Five-Year Plan" two five-year plans to develop this key new material related to the future performance of aero engines.

Compared with the long cycle of titanium aluminum alloy, NB-711 electrochemical hole processing equipment is much smoother, as the key equipment research project of the "Seventh Five-Year Plan", Tengfei Group spent a full five years, and finally took down the subversive processing equipment of the turbine blade air film cooling hole.

This is so important to Ascendas Group.

It is important to know that the previous WD series aero engines or aero-fueled gas turbines, although there is little difference between them and similar foreign products in terms of performance, especially in the application of a large number of composite materials, the service life can be completely comparable with foreign products.

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

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

As for why, the reason is simple: the cost of an aero engine or gas turbine produced by Ascendas Group is much higher than that of foreign brands.

Doesn't it mean that Tengfei Group's cost control is first-class in China?

It also depends on what it is, and the cost of Tengfei Group will naturally be controlled in the field where it is certain, but if you can't even grasp the field where the technology is going, you won't have the ability to control it even if you want to.

Turbine blades for aero engines are one of them.

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

can be a weak mess in metal materials and metallurgy, and he is a proper super student.

The aero engine turbine blades are made of metal alloy materials, even if Tengfei Group is against the sky, after completing the processing of the air film cooling hole, the later treatment must always be done, otherwise it is really looking at the reduction of engine life and scrapping in advance?

The problem is that Tengfei Group can't do it at all in this regard, so it can only choose to outsource to other aviation development factories to deal with it, 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 like this, and leaving professional things to professional enterprises can not only promote the development of enterprises in this field, but also reduce their own costs.

It's just that there is a premise for all this, that is, the technical advantages of the contracted enterprises are very obvious.

European and American enterprises have accumulated for so many years, which is naturally not a problem, but domestic enterprises do not have this advantage, so it has a result, that is, the scrap rate is extremely high.

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 high cost is scary, if it is replaced by other companies, the harmless little problem will be put away, after all, the cost of losing one is really painful.

However, Tengfei Group is not, at the request of Zhuang Jianye, almost rather kill the mistake, refuse to let go, a batch of commissioned processing blades if a piece is unqualified, then this batch of products will not be all recast.

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

Of course, this practice is inevitably criticized by some brother factories, and there is no way, strict quality control is not only the loss of Tengfei Group, but also other contracting plants.

Because of this, the aviation industry has recognized that the work of Tengfei Group is not easy to do, in the words of a retired leader of a large factory: "Tengfei Group's money has nothing to say, but it is very annoying to pick and choose in production." ”

It stands to reason that those brother factories with the support of the ministries and commissions to guarantee the production capacity will be too lazy to take care of the Tengfei Group if they are crazy a few times, anyway, the wages on their side are so much, and the drought and flood guarantee the income, why are the two stinky money of the Tengfei Group as low as a grandson, they are all enterprises under the ministries and commissions, do you have that qualification?

Tengfei Group is really recruiting, after all, it is a rising star, and you have to call those brother factories a senior, what can Tengfei Group do?

However, Tengfei Group can't do this, and the No. 10 project that has been advancing has some tricks.

Other enterprises and units have criticized the approach of Tengfei Group, but the No. 10 project team has seen the new ideas of quality control of the entire No. 10 project from the quality requirements of Tengfei Group for the quality of outsourced components ~~, not only the chief engineer personally came to understand the operation of the entire quality system, but also applied it to the supporting tasks of the various subsystems of the No. 10 project.

You know, after several years of painstaking research, the No. 10 project has begun part of the system trial production and verification, how to control the production quality, the No. 10 project team did not have a spectrum in mind before, now well, Tengfei Group has made a good demonstration, using its own strict control, the quality of the aero engine produced is comparable to similar products in western developed countries.

Since such a high-end product as an aero engine can be required to this extent, Project 10, which is a third-generation fighter, can also be realized.

Therefore, the No. 10 project team completely got rid of the organizational model of the previous ministries and commissions designated supporting production plants, but sent people to find out one factory by one, and then used a similar bidding method to select the enterprises that meet the requirements, and set up a perfect reward and punishment exit mechanism and the competition mechanism between products, forcing those supporting production plants to continuously improve the performance of accessories and strengthen quality awareness.

With the No. 10 project, the bulldozer rumbling forward, Tengfei Group does not have to be so thankless in front, with the supporting No. 10 project, it is finally flickered to the two aviation development production plants, and has been tortured until the NB-711 electrochemical hole processing equipment was successfully put into production.

Of course, even if the two aviation development plants supporting the Tengfei Group know that they have been fooled, they are also willing, there is no way, it is really the role of the Tengfei Group in the entire No. 10 project is pivotal, because in addition to the designated successful aircraft manufacturing company, the main contractor, it belongs to the Tengfei Group has the most supporting projects, reaching 28.6% of the whole aircraft manufacturing
