The shouts in the inner office startled the people outside, and Shi Jun and Lin Guanghua were no exception, both craned their necks curiously to look inside, trying to figure out what was going on.

At this moment, the door of the inner office opened, and Qiao Chenyu walked out in high spirits, compared to the depressed appearance when he went in, it was like two people.

I saw him walk to the telephone and call the long-distance of the capital, with an excited trill: "Chief Engineer He, the thing has been found, it has been found, you remember right, it is in the trial production office...... Yes, yes, that's what you did back then, ...... Okay, as you said, let's do it first, and everything will be said when you come back...... Okay, then I'll hang up first, and I'll pick up the wind for you in the factory then. ”

Putting down the phone, Qiao Chenyu turned his head: "Xiaoshi, a few of you will go with me to the first assembly workshop." ”

Shi Jun couldn't understand why Qiao Chenyu was so contrasting before and after, but seeing Director Qiao's smiling appearance now, he knew that it shouldn't be a bad thing without asking, so he hurriedly called Lin Guanghua and others, and hurriedly followed Qiao Chenyu to the first assembly workshop.

When they arrived at the first assembly workshop, Shi Jun and others knew that the reason why Qiao Chenyu was happy was that Shi Jun found a detailed information on the improvement process of wing siding in the information he found from the archives of the trial production office.

If it was placed in the past, it is estimated that no one may be able to think of it if it is left in the filing cabinet to eat ashes, but as the so-called impermanence of the world, the trial production project that Yonghong Factory is preparing to strive for is very special, especially the strength of the wing is very high, at least to reach more than twice the strength of the wing of the existing fighter, and the weight of the overall model cannot be increased.

At this stage, this indicator is a bit outrageous, but it is understandable, because the trial model is a carrier-based J/R aircraft used on aircraft carriers.

As a key model in the aircraft carrier program, carrier-based fighters and fighters have almost reached a strict level of requirements for the fuselage structure 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 a top priority.

As early as a year ago, the Yonghong Plant was prepared by the troops to start a feasibility study on the aircraft carrier, so it set its sights on the supporting trial production project of the carrier-based J \ Strike Aircraft.

The main reason for this is that the Yonghong plant still wants to make a difference in the national defense and military industry, and the new models that have been launched one after another, the Yonghong factory either has not caught up, or has not been squeezed in and has been brushed down, so that the huge factory can only survive by maintaining the Jian-6 fighter and the turbojet 6 and turbojet 7 engines.

If the troops have been holding the J-6 for a lifetime, the Yonghong factory will not be in a hurry, the question is how can the troops hang themselves on a tree, the J-6 will always be retired one day, and the new model will become the main force sooner or later.

Therefore, Yonghong Factory must improve its technical level no matter what, otherwise once the Jian-6 is retired, even if Yonghong Factory wants to repair aircraft, it does not have the strength, and elimination is inevitable.

The leaders of this trend factory have seen it very clearly and 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, believing that while retaining part of the production capacity of military products, they will go all out to enter the civilian products, while some people led by Chief Engineer He believe that since the Yonghong Factory is a national defense and military industrial enterprise, military products cannot be lost, and they must be transformed to a higher level.

Since the two sides are deadlocked, the two routes are simply parallel, with Director Yu focusing on civilian products to create benefits, and Chief Engineer He is responsible for military products to strive for trial production projects.

Otherwise, the big factories directly under the ministries and commissions are arrogant, and they will grasp it with both hands if they can't talk about it, anyway, they are crossing the river by feeling the stones, and even the central government is groping and reforming at the same time, and it is understandable for Yonghong Factory to do this.

As a result, Director Yu plunged into civilian products and never returned, while Chief Engineer He silently accumulated strength and prepared to take down the task of trial production of carrier-based J&S attack aircraft in one fell swoop.

However, Chief Engineer He's idea is good, the problem is that the army is not opened by his family, and he can do whatever he wants, even if it is a trial model, the army also wants to make a usable model that meets its own conditions, so it attaches great importance to the technical strength of the trial manufacturer.

Yonghong Factory in the trial production of several aviation enterprises, the strength can only be regarded as medium, the technical situation is not outstanding, it stands to reason that at best it is only a role to accompany the runner.

Fortunately, Chief Engineer He's qualifications are old enough, his relationship with the army is tight enough, and he was born in the aviation industry in Northeast China, so he can live in two key factories from Northeast China, so he has the hope of winning.

But no matter how big the role of Renwang is, it can't make up for the technical shortcomings, the most important of which is the strength of the wing wall plates, and the products of Yonghong Factory can only meet the minimum requirements of the air force, and it is equivalent to being unqualified when put on the carrier-based J \ strike aircraft.

On the other hand, the two key aviation factories in Northeast China had just imported six new pieces of equipment from the United States the year before last, and the production efficiency of their wing siding panels had doubled, and the structural strength had also been greatly enhanced.

Otherwise, it would be impossible for the Jian-8 fighter planes produced by the two factories to be well received by the troops, and with these two key aviation factories there, Chief Engineer He could only become an ornament no matter how prosperous he was.

But let him update the equipment and compare with the two Northeast Aviation Plant, Yonghong Factory has the strength, import equipment, that is to use foreign exchange, not to mention whether the superior can approve it, even the long transportation time Yonghong Factory can not afford to wait, not to mention that Yonghong Factory has no extra funds to import new equipment.

Chief Engineer He, who was far away in the capital for a meeting, was worried, pulling his hair, thinking, thinking, not to mention that he finally had an idea and caught a glimmer of light.

That is 73 years he led a set of wing mechanism enhancement process improvement program, originally this set of programs for the large aircraft wing preparation, but with the chief engineer, core technical backbone and all the technical data was dug up by H City, Yonghong Factory's dream of large aircraft is completely shattered.

The process improvement plan for the enhancement of the wing mechanism was naturally gone, and even his formulator, Chief Engineer He, felt that this thing would lie in the pile of old paper until it was old, but it was used at this time, so he hurriedly called Qiao Chenyu in the factory and asked him to arrange someone to find it and see if he could find it.

"I was worried that this thing would be abandoned during a special period, but I didn't expect it to be so well preserved. Qiao Chenyu took a stack of technical instructions and looked at Shi Jun and the others excitedly: "So we have the bottom, although we did a feasibility study at that time, but Chief Engineer He made great efforts, and the target is also the most advanced wing production process of large aircraft abroad, that is, the shot peening process." ”
