Chapter 45

The cry of the inner office startled the people outside. Shi Jun and Lin Guanghua were no exception. They stretched their necks curiously and looked inside to find out what happened.

At this time, the door of the inner office opened and Qiao Chenyu came out with high spirits. Compared with the dejected appearance when he went in, he was just like a different person.

He went to the telephone and called for a long-distance call to Beijing. He opened his mouth with an excited trill: "chief engineer he, I found something. I found it. You remember right, I was in the trial production office Yes, yes, that's what you did in those years, eh OK, just as you said, let's start from here. We'll talk about everything when you come back OK, I'll hang up first. Then I'll meet you in the factory. "

Putting down the phone, Qiao Chenyu turned his head and said, "Xiaoshi, you guys will go to the first assembly workshop with me."

Shi Jun can't understand why Qiao Chenyu has such a big contrast. Seeing director Qiao's smile, he knows that it's not a bad thing. So he quickly calls Lin Guanghua and others and follows Qiao Chenyu to the first assembly workshop.

When I got to the first workshop of the general assembly, Shi Jun and others knew why Qiao Chenyu was happy. It turned out that among the materials Shi Jun found from the archives of the trial production office, there was a detailed information about the improvement process of the wing panel.

If you put it in the past, it may not be remembered that you will stay in the filing cabinet to eat ashes. However, as the saying goes, things are changeable. The trial production project that Yonghong factory is going to fight for is very special, especially the strength requirement of the wing is very high. At least, the strength of the wing should be more than twice that of the existing fighter, and the weight of the whole aircraft can not be increased.

At the present stage, this index is a little too high, but there is nothing wrong with it, because the trial model is a shipborne fighter for aircraft carrier.

As a key model in the army's aircraft carrier plan, the requirement of the fuselage structure of Shipborne fighter has reached a strict level due to the harsh requirements of take-off and landing conditions and the complex and changeable use environment.

In particular, the wing, the most critical component of the aircraft, has become the top priority.

As early as a year ago, Yonghong factory got the army ready to start the feasibility study on the aircraft carrier, so it focused on the pilot project of Shipborne fighter.

The main reason for this is that Yonghong factory still wants to make a difference in the cause of national defense and military industry. The new aircraft Yonghong factory, which has been launched one after another, either failed to catch up or was forced to be swept down. As a result, such a large factory can only live on maintaining the J-6 fighters and turbojet 6 and turbojet 7 engines.

If the army has been holding the J-6 for a lifetime, Yonghong factory will not worry. The problem is how the army can hang in a tree. The J-6 will be retired one day, and the new aircraft will become the main force sooner or later.

Therefore, Yonghong factory should improve its technical level in any case, otherwise, once the J-6 is retired, Yonghong factory will not have the strength even if it wants to repair the aircraft, so it is inevitable to be eliminated.

This trend is very clear to the leaders of the factory. They know that the transformation is imperative, and the key is how to turn.

The vast majority of factory leaders headed by director Yu are optimistic about the development of civilian products. They think that while retaining part of the military production capacity, they should try their best to march into civilian products. However, some people headed by chief engineer he think that since Yonghong factory is a national defense military enterprise, military products should not be lost and should be transformed to a higher level.

The two sides have different ideas, but the starting point is that Yonghong factory is good. Since the two sides are deadlocked, the two routes should be parallel. Factory director Yu is responsible for creating benefits for civilian products, while chief engineer he is responsible for the trial production project of military products.

In other words, the big factories directly under the ministries and commissions are heroic. If they can't get along with each other, they have to grasp both sides. In any case, they are trying to cross the river by feeling the stones. Even the central government is exploring and reforming at the same time. There is nothing wrong with Yonghong factory doing so.

As a result, director Yu's entry into civilian products is gone forever, while chief engineer he quietly accumulates his strength and prepares to win the trial production task of the army's shipborne fighter at one stroke.

However, chief engineer he's idea is good. The problem is that the army is not owned by his family. He can do whatever he wants. Even if it's a trial model, the army also wants to come up with a usable model that meets its own conditions. Therefore, it attaches great importance to the technical strength of the trial manufacturer.

Among the several aviation enterprises participating in the trial production model competition, the strength of Yonghong factory is only medium, and the technical situation is not outstanding. It is reasonable to say that Yonghong factory is only a running role at best.

Fortunately, chief engineer he is old enough, has a close relationship with the army, and is born in the Northeast aviation industry. He can live in two key factories from the northeast, so he has a chance to win.

But no matter how important RenWang's role is, it can't make up for the lack of technology. The most important thing is the strength of the wing panel. The products of Yonghong factory can only meet the minimum requirements of the air force. If they are put on the carrier based fighter, they are unqualified.

In contrast, the two key aviation plants in Northeast China just imported six new types of equipment from the United States the year before last. In addition, the production efficiency of their wing panels has doubled, not to mention the structural strength.

Otherwise, the J-8 fighters produced by the two factories would not be highly praised by the army. With these two key aviation factories there, chief engineer he, no matter how prosperous the people are, can only become a decoration.

But if we want him to update his equipment, we can't compare it with the two Northeast Airlines. Whether Yonghong has the strength to import equipment or not, we need to use foreign exchange. First of all, whether the superior can approve it or not, Yonghong can't afford to wait for the long transportation time. What's more, Yonghong has no extra funds to import new equipment.Chief engineer he, who had a meeting far away in Beijing, was worried. He pulled his hair, thought and thought, not to mention that he finally got an idea and caught a glimmer of light.

It was in 73 that he took the lead in developing a set of technological improvement plan for wing mechanism enhancement. Originally, this plan was designed to prepare for large aircraft wings, but with the chief engineer, core technical backbone and all technical data being dug out by H City, Yonghong factory's big aircraft dream was completely destroyed.

The process improvement plan for strengthening the wing mechanism naturally went to an end. Even his maker, general manager he, felt that this thing would be lying in the pile of old paper until the end of time. Unexpectedly, it was used at this time, so he called Qiao Chenyu in the factory and asked him to arrange someone to look for it and see if he could find it.

"I was worried that this thing would be abandoned in a special period. I didn't expect that it would be preserved so well." Qiao Chenyu looked at Shi Jun and others excitedly with a stack of technical description materials: "in this way, we will have the bottom. Although we did the feasibility study at that time, chief engineer he made great efforts to match the most advanced wing production technology of large aircraft abroad, that is shot peening technology."
