Take Off My Aviation Era

No wonder Liu Chun would say so emboldened, the NB-711 electrochemical hole processing equipment is the key technology equipment that is rarely developed by Ascendas Group in recent years.

Its origin is the unsystematic technical data obtained by H company from Japan that year, which was used to offset the transfer cost of UAV technology from Ascendas Plant to H company.

It's just that the materials at the time were messy and disorganized, and most of them were forward-looking delusions. The few remaining parts could not be applied immediately, and continued investment was needed to achieve results.

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

However, for these chicken ribs, Zhuang Jianye still carefully selected and selected, and finally found two key research directions, one is the material aspect of titanium aluminum alloy; the other is the electrochemical precision used for the machining of turbine blade film cooling holes Hole processing equipment.

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

Therefore, when the national key scientific research project of the "Eighth Five-Year Plan" was applied in 1989, the aerospace ministries and commissions, which were just established less than a year ago, declared titanium aluminum alloy as the key material scientific research project of the ministries and commissions in 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 related to the leap of future aero-engine performance.

Compared with the long cycle of titanium-aluminum alloy, the NB-711 electrochemical hole processing equipment will be much smoother. As a key equipment research project of the "Seventh Five-Year Plan", Ascendas Group spent five full years and finally This subversive processing equipment for film cooling holes of turbine blades was taken down.

This is really important for Ascendas Group.

It should be known that the previous WD series aero engines or aeroderivative combustion gas turbines are not much different from similar foreign products in performance, especially in the application of a large number of composite materials, the service life can be completely comparable to foreign products.

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

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

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

Isn't that the cost control of Ascendas Group is first-rate in China?

It also depends on what it is. The cost of the confident field Ascendas Group needs to be controlled, but if you can't even grasp the field where the technology is going, you will not have the ability to control it.

The turbine blades of aero 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, it is a complete mess, and it is a super partial student.

The aero-engine turbine blades are made of fake metal alloy materials. No matter how the Ascendas Group is going against the sky, after finishing the processing of the film cooling holes, the post-processing is always to be done, otherwise it is really eye-catching. As the engine life is reduced, it is scrapped early?

The problem is that Ascendas Group can't do this at all. It can only choose to outsource it to other aviation manufacturers, and strictly control the quality.

If it is located in the United States or Europe, it would be okay for Ascendas Group to operate in this way. It will not only promote the development of enterprises in this field, but also reduce its own costs.

It's just that there is a prerequisite for all this, that is, the technical advantage of the contracting company is very obvious.

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

You must know that it is a turbine blade. The value of optical materials is outrageous. Coupled with a series of processing, the cost is scary. If this is replaced by another company, the innocuous minor problems will be passed away. After all, the cost of losing one. It really hurts.

But the Ascendas Group is not. At the request of Zhuang Jianye, it is almost willing to make mistakes instead of letting go. If a batch of commissioned blades is not qualified, then all the products of this batch should not be returned to the furnace. Cast.

The consequence of this is that the cost has risen sharply, but it has also ensured the quality of the aero engines produced by Ascendas Group.

Of course, this approach is inevitably criticized by some brother factories. There is no way. It is not only Tengfei Group that strictly controls losses, but also other contracting factories.

It is precisely because of this that the aviation industry in recent years has recognized that Ascendas Group’s work is difficult to do. In the words of a retired company leader: “Ascendas Group’s money doesn’t have to be said, but it’s just picking things up in production. Four, it's very annoying."

It stands to reason that those brother factories that have the minimum production capacity supported by the ministries and commissions will be too lazy to take care of them if they are driven crazy several times by the Ascendas Group. Anyway, the wages on their own side are so much, and the drought and floods are guaranteed. Like a grandson, they are all companies affiliated to ministries. Do you have that qualification? What can you do to your master if you quit.

Tengfei Group is really a trick. After all, it is a rising star. In terms of seniority, you have to call the seniors with those brother factories. What can Tengfei Group do?

However, Ascendas Group can't do this. The No. 10 project that has been advancing is a trick.

Other companies and units have criticized Ascendas Group’s practices, but the No. 10 project team saw the new thinking of quality control of the entire No. 10 project from Ascendas Group’s changing quality requirements for outsourcing components. Not only did the chief engineer himself Come to understand the operation of the entire quality system, and apply it to the supporting tasks of the various sub-systems of the 10th 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 quality of production, the No. 10 project team has not yet figured it out before, but now it’s good. Ascendas Group has done a good job. The demonstration, using our own strict control, just let the quality of the aero engine produced is comparable to similar products in western developed countries~www.wuxiaspot.com~ Since high-end products such as aero engines can be required to this level, As a third-generation fighter jet No. 10 project can also be realized.

As a result, the No. 10 project team completely got rid of the previous organization model of designated supporting production plants by the ministries and commissions. Instead, it sent people to find out one factory by factory, and then used a similar bidding method to meet the requirements. The required companies are selected, and a complete reward and punishment exit mechanism and a competition mechanism between products are established, which forces those supporting manufacturers to continuously improve the performance of accessories and strengthen their quality awareness.

With the No. 10 project, the bulldozer rumbling forward, the Ascendas Group does not have to be so thankless to take the lead. By supporting the No. 10 project, it finally came to the two aviation production plants and tortured until NB. —711 type electrochemical hole processing equipment was put into production smoothly.

Of course, even if the two aviation companies supporting Ascendas Group know that they have been fooled, they are still willing. There is no way. It is that Ascendas Group’s role in the entire No. 10 project is very important, because in addition to the designated successful aircraft manufacturing company. In addition to the main contractor, Ascendas Group has the most supporting projects, reaching 28.6% of the total machine manufacturing
