Take Off My Aviation Era

, The fastest update to take off the latest chapter of my aviation era!

If someone else said it would not be the case for the head of the headquarters, but Peng Chuan and Wei Guangping nodded very positively, and the head of the headquarters knew that it was 80% right.

How can I say that the head of the headquarters is also a person who has come from the war years, and his eyesight is very accurate. Although the previous accompany Peng Chuan and Wei Guangping are like wooden people, they don't know how to talk.

However, the nature of the two people was touched by the head of the headquarters. Seeing that the two people affirmed their agreement, the head of the headquarters asked Zhuang Jianye in relief.

The chief had asked this question. Naturally, Zhuang Jianye could not neglect. He took the chief of the headquarters and other figures to carefully review the processing flow of the whole set of equipment and a few semi-finished products that had not yet been processed. He quickly told Peng Chuan: "Old Peng, you Go and get the samples we made the other day."

Peng Chuan was taken aback for a moment, and immediately reacted, and he ran all the way to the finished product warehouse to get things.

And Zhuang Jianye pointed to the chemical milling equipment in front of him and said: "At present, we have only studied the chemical milling process of a few aluminum alloys. We have not studied the more complex nickel-based alloys and titanium-based alloys, so we don’t know. What is the main production of the 146 factory mentioned by the chief just now, if the alloy structure of the components is complicated, it may be necessary to focus on solving the problem...hehe, after all, our factory..."

Zhuang Jianye said and said, but he stopped talking, with a proper flush of cheeks, he was just right for a look that was weak but was ashamed to show.

Chemical milling is a common process for cutting complex thin parts such as the leading edges of aircraft wings and skins. After all, if two or three millimeters thick blanks are processed by pure machining, it is easy to damage the parts due to poor precision control.

Even with the popularity of CNC machine tools, the accuracy has been greatly improved, and even multi-axis CNC can achieve precision that was previously unattainable, and it can complete the processing of thin and light parts with complex curved surfaces.

However, this is not worthwhile in terms of cost. It is necessary to know that the complex and thin parts of the skin on an aircraft will cost several thousand, let alone the similar parts of the Zeus-3 UAV sold by Ascendas plant to Europe. There are more than three thousand four hundred children.

Divided into dozens of categories, hundreds of varieties.

If each one is to be processed by a multi-axis CNC machine tool, not to mention hundreds of plans for light tooling, and hundreds of CNC programming, which must be replaced anytime and anywhere according to the production schedule.

This is tantamount to an invisibly increased labor cost several times.

What's more, for mass production, the number of such high-precision machine tools must not be small. If so, that’s all. The problem is that the types must be all large, medium, and small. Shaft machining center, can't get three or four meters long fuselage bee waist curved surface.

Similarly, a machine tool that can process a body with a diameter of seven or eight meters cannot finish machining parts the size of a fingernail.

And similar parts are not one or two, but thousands or tens of thousands. If they are all processed with this high-end machine, no one can play it.

On the other hand, chemical milling is much more cost-effective, as long as the actual situation is adjusted, the temperature is controlled, the parts to be processed are reserved, and then immersed in a chemical pool, and the erosion effect of the chemical reaction is used to complete the machining process similar to machining. , Not only is the batch large, but also repeatable, and the cost will naturally be greatly reduced.

It's just that this seemingly uncomplicated process has two core points. One is the real-time measurement of the parts when the chemical reagent is soaked; the other is the preparation of the etching solution based on the characteristics of the material itself.

The former Ascendas plant is not a problem. Thanks to the accumulation of laser precision measurement, Ascendas Plant has cooperated with the North China Institute of Optics to carry out other research on precision measurement, which is already at the forefront of the country.

What makes Tengfei Factory a headache is the accurate parameters and detailed metallographic characteristics of other alloy materials. There is no way, how is Tengfei Factory, it is impossible to be comprehensive. The material is another technology tree, and it is a huge hole. The two pieces of aviation development and special equipment can’t be extricated. Add a composite material. Ascendas Factory has long been exhausted physically and mentally. It is really unable to jump into the third pit anymore, so a few aluminum alloy corrosive fluids are used. Had to stop.

But the problem is that it won’t work just like that. After all, nickel-based alloys and titanium alloys are widely used in manned aircraft in the future. If you don’t figure it out, it will be very detrimental for Ascendas to enter the field of manned aircraft.

Therefore, Zhuang Jianye put out an Oscar-winning performance, hesitated and stopped, and was embarrassed. To put it bluntly, he wanted to use the head of the headquarters to let the national team go out, and then take off the factory to make some profits.

As a result, the head of the headquarters didn't even look at Zhuang Jianye, and said, "You don't need to worry about this. As long as your product performance is good, I will coordinate with relevant departments to tackle key problems..."

As soon as this remark came out, Zhuang Jianye's heart trembled, and his heart was finished. He was such a small piece of fresh meat to play with the old man. It is not clear that he is looking for abuse. Now it is all right. The head of the headquarters saw it through the heart, liver, stomach and kidney Thoroughly, it's cheaper to pick it up, so if you don't pick it up as cheap, just burn it.

So Zhuang Jianye's glorious eyes fell quickly and sadly, although he still agreed with a smile, but his spirit was much weaker than before.

The head of the headquarters smiled at the declining Zhuang Jianye~www.readwn.com~ and smiled more and more brilliantly, and then turned his head to look at some parts that were still unclear by the extremely flipped side. The leader ordered: "This I think this kind of basic research is still led by your ministries and commissions. If you can contact the aerospace department, the two of you will work together to select capable companies, units, and universities to participate. This is called concentrating power to do big things. This is our characteristic, and it is also our institutional advantage."

Then he pointed to the previous chemical milling equipment and continued: "The company that can build such equipment is very good, and it can make appropriate policy tilts."

The leaders of the ministries and commissions nodded quickly, which was regarded as an instruction. After returning home, the official documents would be sorted out. As for Zhuang Jianye, he breathed a long sigh of relief. He finally caught up with the national team, and a big rock fell on the ground.

At this time, Peng Chuan came over with two washbasin-sized stiffener skin parts. The middle-aged officer named Zhao hurriedly greeted them and held the parts in his hands. The skin on the top seemed to be a piece of paper. On the four stiffeners, they are so thin that they make people's heart tremble, for fear that one of them will be broken by accident.

The middle-aged officer surnamed Zhao also did it very carefully with the centralized measuring instrument, and then nodded in satisfaction. Then he turned to look at Zhuang Jianye and asked: "The quality of the parts is very good, indicating that your equipment is very good. I don’t know if you have any. Not interested in transferring this set of equipment?"
