Chapter 533 Are You Watching?

And such a good thing?
Zhang Qihang was very pleasantly surprised by Andre's statement. He never thought that Andre would not only come here by himself, but would even take the initiative to find some Soviet experts for him. .

Of course, Zhang Qihang couldn't miss such a good thing. He didn't even have time to pretend, and said quickly: "Mr. Andre, are you sure? Are you really willing to introduce some experts for us?"

Andre smiled a little embarrassedly, and said: "Mr. Zhang, it's already reached this time, so I won't hide it from you: Before I came to Huaxia, many friends entrusted me to understand the situation of your company... um , you also know that the construction machinery industry in Russia is in a downturn, so..."

That's it!

Only then did Zhang Qihang realize what was going on: Dare to say that the entire Russian mechanical engineering industry is in a cold winter, and everyone's life is difficult, so for this opportunity to visit China, not only Andre, but the entire Russian mechanical engineering industry The engineering industry is secretly paying attention, as long as they are sure that this is a good opportunity for them, they will come to China... It is understandable, the feeling of being hungry is really uncomfortable.

Knowing what was going on, Zhang Qihang readily agreed: "Of course, no problem, Mr. Andrei, since you worked in the All-Soviet Engineering and Road Construction Machinery Research Institute in the former Soviet Union, you are very interested in our mechanical engineering in China. It is our honor that you and your friends are willing to join our Huateng Industrial Group..."

Having said that, Zhang Qihang changed the subject and asked Andre: "By the way, Mr. Andre, do you have friends from the Miri Design Bureau and the Kamov Design Bureau? The two design bureaus are on the line?"

Andre nodded and said, "Mili Design Bureau and Kamov Design Bureau? I'm not very familiar with it, but if necessary, I can get in touch...Mr. Zhang, let me ask, you should know two The Design Bureau makes helicopters, so they don’t seem to have anything to do with Huateng Industrial Group’s business, do they?”

"I have taken a fancy to their ability in the main reducer of the helicopter," Zhang Qihang did not hide it, explaining: "Andre, you should know that the main reducer is the core of the helicopter except the engine. components, and the main reducers used on helicopters are basically planetary structures, and most of the automatic gearboxes used on construction machinery are also planetary structures..."

"Look at my brain!"

Before Zhang Qihang finished speaking, Andre slapped his forehead with a slap, with an annoyed look of "such a simple truth, why didn't I think of it?!", he finally knew why Zhang Qihang was beating Mili The idea of ​​the Design Bureau and Kamov Design Bureau.

From a mechanical point of view, what is the core of the automatic transmission of construction machinery: one is the hydraulic torque converter, and the other is the overall structural design. However, in the world today, the main structure of automatic transmissions used on construction machinery are all It is planetary, and when it comes to planetary power transmission structure, what is higher than the structural design, material and processing technology of the main reducer for helicopters?

With the power of the Mi-8 medium-sized helicopter equipped with the largest number in the Soviet Union, it is equipped with two engines with a single power of about 2000 shaft horsepower. That is to say, the main reducer on the Mi-8 helicopter has to withstand an input of about 4000 shaft horsepower. Power, while requiring the main reducer to have extremely high transmission efficiency and service life, its own weight must be strictly limited, so as to reduce the dead weight of the helicopter as much as possible and increase the load.

For a long time, the Soviet Union has been unable to compare with Europe, the United States, Japan and other countries in terms of automatic transmissions for large-scale construction machinery. Is it downgraded to use in consideration of the manufacturing cost, isn't it also able to crush the counterparts in Europe, America and Japan? !

Exasperating!
The kind of anger that makes the whole person feel uncomfortable and wants to explode!

Seeing the frustrated Andre, Zhang Qihang thought for a while, and guessed why this guy was angry. Also, when he thought that the problem that had plagued the entire industry for so many years could be solved so easily, and it was solved The solution is in my own home, but I never thought of it. After decades of hard work, there is no effect. Who wouldn't want to explode in place?

But since Andrei is about to become a member of his own company, Zhang Qihang has to find a way to comfort him: "Mr. Andrei, the gap between the Soviet construction machinery industry and the West in the field of automatic transmissions is actually not your fault. on the head."

"How to say?"

"It's very simple," Zhang Qihang explained: "In countries with highly developed market economies such as Europe and the United States, exchanges and interactions between various industries are frequent. After many high-tech applications are applied in one industry, they will gradually be distributed to other industries. Industry, give full play to the value of this technology.

But you know the situation in the Soviet Union. There is actually an invisible but real barrier between various industries. For example, there is almost no communication between your construction machinery industry and the aviation industry. Transmission, a highly mature and reliable technology in the aviation industry, especially the helicopter industry, has become the technical ceiling of your construction machinery industry, so you say, can you be blamed for this responsibility?
So in the final analysis, there was a problem with the top-level design of the Soviet Union, and such a problem was not thought of. "

From this point of view, it seems that this is indeed the case...

Andre was silent for a while, and finally he felt much better. He nodded and said, "You are right."

Zhang Qihang nodded with a smile.

"I know what to do and who to contact when I go back," Andre responded, and then said: "But Mr. Zhang, you'd better be mentally prepared accordingly, like the chief designer of the Mili Design Bureau. Teacher, deputy chief designer, etc., I definitely can't do anything about it."

"The chief designer and deputy chief designer of the Miri Design Bureau and the Kamov Design Bureau?" Zhang Qihang smiled and waved his hands again and again: "This kind of talent is a national treasure in any country, and I never dared to think about it." !
Well, I remember reading a report that said that in the Soviet period, the design of the main reducer of the helicopter was jointly developed by the research and development unit of the supporting engine, but the main reducer of the Mi-26 helicopter was developed by the Miri Design Bureau itself Research and development, Mr. Andre, as long as you can recruit a few designers, engineers and designers who have participated in the design and production of the final drive, I will be satisfied. "

Andre also breathed a sigh of relief: "If it's just the people involved in the project, then it's not a big problem."

Zhang Qihang continued: "There are also talents in electromagnetics, mathematics, computers, and logic algorithms."

"Yes, these are also necessary."

Andre nodded hastily. What Zhang Qihang said is also one of the core technologies in the automatic transmission of construction machinery. Of course, talents in these fields are also necessary.
