Chapter 521

In March last year, several leading figures in the scientific and technological circles proposed to the Central Committee that China should formulate its own major scientific and technological development plan so as not to be eliminated in the fierce international competition in the future.

As soon as the proposal was put forward, the central government attached great importance to it and soon gave instructions. Because it was put forward in March 1986, the high-tech development plan was named "863 Plan".

So far, China's "863 Program", which is the counterpart of the "Star Wars Program" of the United States and the "Eureka program" of Europe, was officially born.

Tengfei group, which has been tracking the latest science and technology in the aerospace field, naturally becomes the focus unit of the "863 Plan", especially in the field of new materials. It doesn't matter how Zhuang Jianye acts. Director Zhao of aerospace applied for many research projects of the aerospace technology R & D center under the name of aerospace new material technology, and obtained approval last month.

Not long ago, the first batch of research funds had been allocated, totaling 150 million yuan, which surprised Zhuang Jianye. For so many years, asking for funds from above is like squeezing toothpaste. It's all pressed out little by little. How can there be such a happy time? And hundreds of millions! In his surprise, Zhuang Jianye finally realized that he seemed to be too Buddhist, but he didn't pay attention to it. You know, it's money. You can't get along with money.

So Zhuang Jianye took action. While Luan Heping and Ning Xiaodong were digging up the wall, he went to the capital to find the chief and the leader. He sincerely hoped that all the projects under research of Tengfei group would be included in the "863 Plan".

The leaders at the higher level are not stupid. The "863 Plan" is to develop cutting-edge technology. If all R & D projects are accepted, what will it be.

Therefore, after reviewing the materials submitted by Zhuang Jianye, the expert group of "863 Plan" only gave Zhuang Jianye three specific general directions: the first is special aeroengine; the second is modern assembly technology of aviation equipment; and the last is precision welding technology.

Each special project is required to propose a specific development direction for specific budget allocation.

Zhuang Jianye still wants to fight for it. Unfortunately, he can't wring his arms and legs. He has no choice but to think in these three directions. The first two are OK. After careful study, the focus of the aeroengine project is on the 6 MW core aircraft, that is, the hx-11-6 core aircraft.

Because the turbofan, vortex shaft and gas turbine derived from this can meet the power requirements of most of the light fighters, medium and long range regional airliners, high-end business aircraft, light and medium helicopters, as well as the gas power plant and small power plant gas turbine power plant of combat ships under 3000 tons.

At that time, Tengfei group will not only move around on UAVs and light small aircraft, but will really develop towards aircraft with a take-off weight of more than 20 tons. If it goes well, it is not impossible to touch the single engine light fighter or the double engine medium fighter.

As for the second one, we don't need to think much about it. There is only pulsating production line. Although Tengfei group has made great progress in this aspect, some supporting equipment has not been deeply optimized, and the coordination in many places is not satisfactory.

In addition, Tengfei group is also preparing to gradually deepen the pulsating production line of aircraft, and explore the pulsating production assembly scheme of aero-engine and even long-range carrier rocket or missile. Therefore, the construction of the pulsating production line of aircraft is not the first step in the long march.

These two directions can not be said, the only uncertainty is the last one, precision welding technology, in addition to personnel factors, the main technical path is the difference.

Many people think that since Europe and the United States have started large-scale application of electron beam welding technology, there is no consideration, just follow up.

However, a few people think that although the electron beam welding process is advanced, it is difficult and poor in adaptability, which can not represent the future development direction of precision welding. They think that we should make in-depth research to find a new direction that is more in line with the future development.

These two groups are not only in the "863 Plan" expert group, but also in the Tengfei group.

However, with the breakthrough of carbon dioxide laser in North China Institute of optics, the debate has come to an end.

Because this frontier project led by Hu Rongyi, in the preliminary experiment, the welding seam of the parts was reduced to 25 μ m, that is, 25 μ M.

What is the concept of 25 microns? The diameter of human hair is generally 0.05 to 0.08 mm; 25 microns is equivalent to 0.025 mm. In other words, Hu Rongyi's experimental weld width is smaller than that of a single hair.

Let alone with the naked eye, that magnifying glass can't find the weld above.

If this is not enough, the key is that the welding integrity rate using CO2 laser has reached 100%, that is to say, the parts do not need special treatment in the early stage, and they do not need heat treatment after welding. The most important thing is that they can operate in normal environment without vacuum environment. Only in special cases, they need some inert gas protection.

This greatly expands the scope of use, and because of this, it can be used as an alternative to the electron beam welding process and become the leader of the new generation of precision welding technology.Zhuang Jianye is the last person who wants to run after other people's buttocks. The suffocation feeling of trying to catch up with others and always falling behind is really too painful. Instead of running to the black, Zhuang Jianye prefers to run the snake like curve like a famous mountain in autumn. That kind of cold overtaking is the thrill of making a lot of money.

So at the beginning, he was on the side of laser welding technology, but he didn't have credible test data to prove it. In addition, the instability of talent team caused by Liszt's various kinds of wall digging made Zhuang Jianye only want to push forward.

Now, Peng Chuan not only sent the urgently needed experimental report, but also firmly stood on the side of Tengfei group, so Zhuang Jianye could apply for it. You know, it's a large-scale R & D project of nearly 100 million yuan per year, and he doesn't want to slip away.

As for the recent wave of going abroad sweeping the aviation industry, since it's going to rain and my mother wants to get married, even the higher ministries and commissions can't take care of it. Zhuang Jianye doesn't have the heart to take over the responsibilities. However, Liszt, who is more cheerful at this time, still needs to find a way to beat him.

Four ej9 electron beam welding machines?

Has the European and American airworthiness certificate of plateau Eagle series been completed? Has the European and American airworthiness certificate of the twin engine regional airliner derived from the advanced light transport platform been applied for? What did not finish dares everywhere to have fun, oneself is what thing, in the heart does not have the spot to force the number?

What? How could Lister be obedient?

It's very simple, because Zhuang Jianye has enough black materials. In addition, during this period of time, the European actors company was gradually emptied, and it was handed over to Liszt through operation. Another big pot was pressed down. Liszt acted obediently, and everyone was happy to earn their own money. If it was a big blow, Zhuang Jianye had many ways to make Liszt not even qualified to be a tramp.

So after a few days, Liszt became the pawn of Zhuang Jianye and lobbied around with the products of Tengfei group, ready to fill the big hole.

……

Just as Zhuang Jianye was busy with the internal affairs of the take-off group, Zheng Quanli looked at the leader of the airborne troops in front of him at an airport in the southeast coast: "this is not good!"

"If there's something bad, it's not a real dead man. If you don't fight well, the funds for next year will be reduced by more than half. Anyway, I've already said so clearly. How can you do it by yourself?"

After that, the commander of the airborne troops went away with his hands behind his back as if nothing had happened. Zheng Quanli sighed, and immediately looked at the flag of the sixth special operations battalion of the Royal Thai army not far away. His face became a little strange. How should we fight this battle?
