Southwest Science and Industry does not have the spare energy to reverse complete the imitation of 31F, but if it can get an engine overhaul line directly from the Soviet Union through formal channels, this is another matter.

First of all, in terms of the huge number of 31F engines after the Republic, there is no production line, but there is absolutely no overhaul line.

When the time comes, if there is a slight problem, it will be repaired, and it will really collapse, and if the overhaul line is built in the country, it can also save the army and the country a lot of money and foreign exchange.

But then again, if you can get the overhaul line through the regular channels, then the regular channels can also get the production line, although the Soviet Union is not willing to sell it now, but when the Soviet Union collapses soon, as long as you work harder, will you be able to get it?

At first glance, such an idea seems to be quite feasible, but the fact is that the 31F engine, which is the national weight of the Soviet Union, was also tightly covered even in the Russian era, and that thing was the laying hen of the entire Soviet aircraft engine industry.

With the rapid occupation of the international market by the Su-27, the 31F engine has also been introduced to various countries, and the life of this engine is far less than the life of the body.

It is about 5,000 hours for a Su-27 to be scrapped, and the life of the 31F engine is 900 hours, and if it is 1,000 hours, a Su-27 will use up 10 31F engines in a lifetime, which is not possible to extend the life of the Su-27, so that more 31F will be used.

Based on these preliminary estimates, we can know the annual production of 31F, and it is not at all true that after the collapse of the Soviet Union, the entire Russian aircraft engine industry was fed by 31F.

is such a thing, you expect Mao Zi to make a mistake and not know how to treasure it, and will sell the production line to the Republic at a low price, which is simply unreliable in the unreliable.

Of course, it is also possible to estimate from these numbers how many 31F engines will be used in the future. No. 10, the original 27 purchased, and even the No. 11 that will be assembled and copied domestically in the future, the number of engines to be used is four digits.

Much, right? It is indeed a lot, and I am afraid that the number of 31F engines used by the Russian Air Force after the disintegration is not far behind. However, the republic has its own strengths, and the previous republic lit up its own unique technical route.

In the development process of Taihang engine, because it is an American engine route, it lights up a lot of technologies that have a bonus to the life of the engine, so there are a series of technologies such as laser impact strengthening.

Of course. The 31F engine blade repair technology researched by the Republic 05719 factory on the previous side has successfully extended the life of the 31F engine to 1500 hours (the 31F overhaul line of the previous surface is in 05719), as long as the 31F to 05719 overhaul once, and then the life of the engine has risen to 1500 hours.

With this technology, it is very effective in reducing the amount of 31F purchased by the Republic, which is the advantage brought by the overall industrial progress of the country.

Similarly, it seems that the six masters purchased by Pakistan on the side, the turbojet 6 engine used on it was refurbished and assembled in the United Kingdom, and the performance and life of the original turbojet 6 of the Republic were immediately increased by a lot.

The same incident was repeated after the 31F of the previous face republic, after the turbojet 6, except that the country that produced the engine was changed. And the republic has become the side of the engine repair in the blink of an eye.

And now to this plane, Southwest Science and Industry has the last face 05719 factory soul figure Xiang Qiao, if it is introduced to the 31F engine overhaul line is the best, but also to restore the previous face of the scenery deeds.

Moreover, according to Yang Hui's idea, this time to introduce the 31F engine overhaul line, naturally it can also be connected to the Soviet 31F engine production unit, and Southwest Science and Industry is still counting on being the upstream supplier of the 31F engine in the future.

After all, there is a good way to grow, there is the life of the Southwest Science and Industry turbofan 10 engine 1400 there, plus the Southwest Science and Industry in order to develop the turbofan 12 to a variety of new technologies. After the introduction of the 31F, if you can't quickly come up with a plan to increase the life of the engine, you will be killed head-on.

……

Yang Hui thought a lot along the way, and also had a lot of communication with the Air Force and Vice Chairman Liu. After understanding the specific thoughts of the top management, I also had more specific thoughts about this trip to the Soviet Union.

When the Il-62 landed at the airport of the Soviet Union, Yang Hui could even feel the joy of this plane, a kind of taste of leaving home and returning to the eldest child, and the local accent had not changed and his sideburns had faded.

The person who came to pick up the airport this time cannot but be regarded as grand, after all, Vice Chairman Liu is already a senior member at the level of vice president of the country. It is definitely the highest-level team to visit the Soviet Union after the Sino-Soviet conflict.

The corresponding Soviet side also sent an equal team to meet him, and Yang Hui was at the back and least noticeable, along with the logistics staff, and only stepped off the plane at the end.

After all, I went to Ukraine to Taobao in another capacity, and now it's better to keep a low profile, although the possibility of being found out is very small, but pay attention to it!

Yang Hui did not participate in a series of other itineraries prepared by the Soviet high-level for Vice Chairman Liu, and Vice Chairman Liu also knew what Yang Hui wanted to do, so he didn't ask anything more, and only left a sentence for Yang Hui to pay attention to, and not to go too far during the event.

Yang Hui knows this, and it is definitely impossible to mess around at such a critical moment now, but this time Yang Hui's identity is the real Yang Hui himself, the general manager of the famous Southwest Science and Industry Company of the Republic.

Moscow, which is also a good place, is a third of the Soviet aviation industry in the vicinity, which is really exciting......

When he found Chief Teacher Yu and his party, Chief Master Yu happened to have something to say to Yang Hui, looking at the red light on his face, it really made Yang Hui curious.

Chief Teacher Yu is such an old man, it must be right to say that he has seen strong winds and waves, the last time I saw Chief Master Yu so happy, it was the Jian-74 finalized production, what is the good thing this time, can make Chief Master Yu so happy?

After being a little curious, he stopped being pretentious, and without saying a word, he followed Chief Master Yu to an open place and saw that there was no one else nearby.

Only then did he ask: "Yu Lao, what can make your face red with excitement at your age, this is very rare!" Why don't you tell me about it now, and make me happy! ”

During the inquiry, Yang Hui didn't pay much attention to it, after all, he didn't know what was going on, and of course there was no need to make a very formal appearance.

But the next moment, when Chief Master Yu said the words, Yang Hui almost didn't jump, the news was really exciting, really too ......

Some of them didn't quite trust their ears, and after forcing themselves to be quiet, they cautiously asked again to confirm whether this was true or not.

"Yu Lao's words are serious, someone over there is someone over there who communicates with you privately and wants to make some deals privately?"

The empty outdoors, after Yang Hui finished speaking, the whole neighborhood seemed quite quiet, waiting for the chief engineer to confirm again whether there were really people from the MiG Design Bureau who had come to contact him privately, as he just said.

If it is correct, Yang Hui is willing to cooperate with the MiG Design Bureau, although the MiG has been declining over the years, and the 27 will overshadow the limelight of the 29 as soon as it comes out, but it is also the oldest fighter design bureau in the Soviet Union.

A lot of technical accumulation is still drooling, 29 failure can not be blamed on the MiG Design Bureau, they are in strict accordance with the design requirements to do the design, as long as the design requirements are met, it proves that the MiG Design Bureau is still excellent.

Now, the technology of the MiG Design Bureau is still at the forefront of the world, and it deserves Yang Hui's attention, and it is even more worthy of Yang Hui picking up the hoe in his hand and digging the foot of the wall hard. (To be continued.) )xh:.74.240.212
