Chapter 551

Not only Professor Zhao was surprised, but also Tong Xia, who had a plain face, had a slight wave. She looked at Zhuang Jianye by accident, not to mention Wu Ping, who had already forgotten what to persuade or not. She was surprised and envied and asked: "really? Mr. Zhuang, does our group also have electron beam welding machine? It's German, it's French? "

Zhuang Jianye suddenly a brain black line, heart said you Xiangzhou factory seems to have not formally merged into the Tengfei group, how to become us?

Wu Ping also felt that he was a little too reserved. Just as he wanted to explain a few words, he heard Professor Zhao over there say: "Xiaozhuang, when I first participated in the introduction of technology and equipment of French 'dolphin' helicopter, it involved electron beam welding machine.

Because the price in France was too expensive, it was later transferred to West Germany, but only the electron beam welding gun and supporting power supply were introduced. Domestic universities and scientific research institutes were responsible for the development of vacuum chambers. A total of five sets of vacuum chambers were made. Two sets were given to the manufacturer of vortex shaft 8, and two to the Northeast aviation development plant. It is said that the remaining set was taken by the Aerospace Department, and it will not fall into your hands "Right?"

Electron beam welding machine has a wide range of applications in aerospace, and Tengfei group is a rare enterprise across the two business sectors of aerospace.

Especially in the field of aerospace, many people in the industry highly recognize and praise Tengfei group. Some people even say that without Tengfei group, the domestic aerospace industry may go back ten years.

This is in sharp contrast to the criticism of the aviation department that Tengfei group is not only focused on money, but also ignored. This is also an important reason why the reputation of Tengfei group has become increasingly polarized after the establishment of the Ministry of Aeronautics and Astronautics.

Because of this, many cadres of the old air port even said bitterly that the Tengfei group, which was clearly born in the air port, now looks like the old aerospace group.

As an authority in the aviation industry, Professor Zhao has heard about these things for a long time. Although he can't touch what Tengfei group provides for the Aerospace Department with his authority, it's not difficult to see from the evaluation of the Aerospace Department on Tengfei group that what Tengfei group does is absolutely right.

Based on this, there is nothing wrong with the assignment of the electron beam welding machine to Tengfei group, which was taken by the Aerospace Department. A manufacturer that can provide important products to the Aerospace Department can't give too much support.

And this also makes Professor Zhao calm face a bit more rich smile, no matter how, the electron beam welding machine also has a great help to the production of helicopters, which is undoubtedly good news for Professor Zhao.

With good news, I'm in a good mood. When I'm in a good mood, the old man talks a lot: "en ~ ~ Yes, this is the real family background. I didn't come in vain this time, and finally I can see something good. I remember that when Xiao Tong and I participated in the introduction of the dolphin helicopter a few years ago, we worked on the electron beam welding machine for more than three months."

"Three months and twelve days." Tong Xia in the side added, the voice is very clear.

Professor Zhao nodded: "well, it's really long enough. In the end, I just bought the core parts and made an electron beam welding machine which is 2.1 meters long, 1.3 meters high and 1.1 meters wide. It brings the technology in this field closer to the world's advanced level, and fills the domestic gap. I think the Aerospace Department is also interested in this point, so it's going to have a set Eh, why didn't you see gdh-15 electron beam welding machine? "

Talking about the past and the advantages of electron beam welding machine, the group came to a large factory building. Just after entering Professor Zhao, they did not see the familiar electron beam welding machine.

Zhuang Jianye pointed to a huge equipment about 10 meters long and 4 meters high in front of him, and said with some modesty: "Professor, this is the electron beam welding machine used by our group, the model is ej9. We applied with our superiors for the gdh-15 electron beam welding machine, but we didn't approve it."

"Ah ~ ~ if it's not approved to you, then you Make a big EJ9？”

At the beginning, Professor Zhao didn't react. He was very calm and smiling, and his gray hair was not disordered. But he realized something at the next moment. He looked up at the ej9 electron beam welder in front of him, and his old eyes widened as if they were splitting. His tone of voice immediately changed.

I want to say that if you didn't get a small one, you'd get a big one. I don't think it's right for the electric room. I changed it to ej9, but I'm so excited. I'm obviously surprised by the electron beam welding machine.

Not only Professor Zhao, but also Wu Ping and Tong Xia were surprised to see the electron beam welding machine in front of them. They were incredible. You should know that they were not people who had never seen the world. Following Professor Zhao, the authority, they had never seen anything good, but they were shocked by ej9.

Gdh-15 electron beam welding machine is really good. The core technology is West German technology, which is not bad as a whole. It can be compared with ej9, which is 7.5 meters long, 2.8 meters wide, 2.5 meters high, 53.2 square meters in space, with 45KW and 110KW electron beam welding guns and automatic welding ability.

The gdh-15 electron beam welding machine, which is 2.1 meters long, 1.3 meters high and 1.1 meters wide, can only be regarded as a younger brother. Oh no, a small character has to be added in front of the younger brother.We should know that gdh-15 electron beam welding machine has been able to do a lot of things in the production of engines and aircrafts that we couldn't think of before.

Ej9, which is 7.5 meters wide, 2.8 meters wide, 2.5 meters high and 53.2 square meters in space, is more than ten times that of gdh-15 electron beam welding machine, so what it can do is even more unimaginable.

“EJ9？ The core welding equipment of F-14 central wing box

I don't know how long after that, Professor Zhao, who was standing in front of ej9 electron beam welding machine, finally regained his mind and asked, but before waiting for an answer, he said to himself, "yes, yes, that's ej9."

Then he turned his head and looked at Zhuang Jianye, pointing to what was being processed inside and asking, "what is being processed inside?"

Zhuang Jianye nodded: "it's the central wing box of the advanced light transport aircraft we are developing."

"En ~ ~" Professor Zhao nodded, then stood outside the safety line and carefully looked at the processing process inside. He sighed with satisfaction: "the space is so big and the efficiency is so high, but it's a pity Quantity... "

"Well Professor Zhao, there are four sets of equipment of the same type in our group. You only have one set in front of you. Another set is in the zero degree factory, and the other two sets are in the Tengfei aviation power factory. "

Professor Zhao just wanted to express his regret that ej9 was good, but the singular number was too small. After listening to Zhuang Jianye's introduction, he opened his eyes again uncontrollably, and even though he had some scattered white hair, he suddenly turned back and changed his tone: "you have Four sets? "

Zhuang Jianye modest smile: "originally want to do ten sets, but you also know that the western countries see this thing closely, it is difficult to get, finally only get four sets, otherwise Well Professor, what's the matter with you? Don't roll your eyes, ah Professor, don't scare me... "
