Since the damage tolerance design can be released in advance, it is easy to do. In order to introduce the damage tolerance design into the new engine design, it is necessary to modify the engine design specification, and the modification of the specification is definitely to be carried out, and now it can be reformed with both.

It was not possible to fully adopt the British code in the design of the new engine, and the conversion of the imperial unit to the metric unit adopted by the republic alone was a major problem. The so-called introduction of the imperial specification in the development of new engines is just the introduction of an idea and method.

Thinking of this, Yang Hui felt that this revision of the specification could not be a small fuss, and just tinkering could not achieve the effect, and it must be completely turned upside down and the old look renewed.

"Director, I understand what Elder Wu means, now Elder Wu is letting us secretly carry out this work in private, and the Ministry of Aviation above doesn't know about it, right?"

Not to mention that this Yang Hui has ideas and does things like ghosts, and now Director Bai admires Yang Hui's cleverness.

"That's right, we won the engine project and rushed back non-stop, but it was still not as fast as Chief Master Wu, and as soon as we sold the tickets, Wu Lao found me. He introduced the Hongqi factory to us, and at the same time, there was this hot potato, and now it is very difficult for us to reform the design specifications. ”

It's not just difficult, it's very difficult, you have to revise the design specifications, so what else is there to dare to do in this 0011 base, it's too bold, it's strange not to make a plank, the road to reform has been difficult since ancient times, and it is normal for Director Bai to sigh.

It is difficult to revise the design specifications, but now it is the least difficult time for the base to modify, on the one hand, the engine development funds are provided by foreign parties, and the most powerful weapons used by the Ministry of Aviation to card the design factories below in the past are gone; On the other hand, the reform has the support of Wu Lao, as the father of the aero engine of the Republic, Wu Lao still has some influence.

Yang Hui analyzed various reasons to Director Bai, and strongly persuaded Director Bai to quietly reform in secret, only if he is willing to reform, Yang Hui can continue to introduce damage tolerance design ideas in the reform.

"Director, I think the reform must be carried out. Now the price we have to pay for reform will be the smallest, and reform is bound to be carried out, and we must dare to be the first in the world. It is still necessary to make your voice heard, and prestige is still very important. ”

Director Bai doesn't do too much technology, but he does a good job administratively, and he understands what Yang Hui said, if he doesn't have prestige. In the future, it will be at a disadvantage in the competition for domestic talents and projects.

Director Bai had already made up his mind about the reform, but he was still thinking about how to proceed.

"Reform must be carried out, but the means are very important, and if the means are used correctly, a lot of risks and objections can be avoided."

Yang Hui took the opportunity to make a suggestion: "Director, the risk is to be taken, and the means depend on the director, I want to make a suggestion now." I don't know how much you know about damage tolerance design, but what I'm going to talk about below is related to damage tolerance design. ”

Director Bai, who is an administrative manager, if you ask him advanced technical questions. He really couldn't answer. But when it comes to the idea of design specifications, Bai Suoshang has really studied it carefully. Director Bai has carefully studied the damage tolerance design of the relatively hot fire that has been studied internationally in recent years.

"I know a little bit about this, which is to introduce the concept of economic life into the design of the new machine, increase the life of the engine, and achieve the optimal throughout the life of the engine. If this succeeds, it will certainly be another revolution, especially for countries that are underfunded. ”

"That's right, what I'm trying to say is to introduce damage tolerance design into the design of the new engine, anyway, this time it's going to be reformed, so we might as well do it thoroughly. On the surface, we are absorbing the strengths of the British design code, but secretly we can run the damage tolerance design idea through the design idea of the new machine. ”

The idea put forward by Yang Hui is not bold, on the one hand, this guy wants to carry out design specification reform and gain prestige. On the other hand, it is necessary to darken Chen Cang to engage in damage tolerance design, which is really walking a tightrope.

Yang Hui's bold behavior is very feasible in the opinion of Director Bai, if the damage tolerance design can get a better effect, it will definitely be a shot in the arm for the new engine.

Not only can the engine be greatly improved in terms of economy, but also in terms of life. Now the Western engine surpasses the Republic in hard technology, and the engine designed under the same design idea naturally exceeds the domestic one.

However, if the damage tolerance design is introduced into the new engine design, then the new engine will definitely exceed the domestic general life data in terms of life. It is even comparable to the life of Western engines, of course, this premise is compared with those engines in the West that do not adopt damage tolerance design, which is the advantage of defeating opponents in soft power.

Director Bai thought for a long time, and then asked Yang Hui what he thought: "Yang Hui, what you said is not impossible, I think about what you said, there is no problem in all aspects, but we are very short of time, we want to introduce damage tolerance design, we have to add a lot of test items, and it may be too late in time." ”

The damage tolerance design needs to test the fatigue fracture data of various parts, and these tests are new test items. Damage tolerance designs are built on huge test data, and without enough test data, who knows when the part will break.

If you want to get enough design data, you need enough time and money, and you don't have to worry about the funds, but the time is indeed a little tight, but this is not unsolvable.

"This is not a difficult problem, we still do it in accordance with the fatigue safety life design in the early stage, and the damage tolerance design is a controllable risk on the basis of fatigue safety design, so we can still take into account the time, as long as we continue to test in the later stage, we can get enough data to carry out the damage tolerance study of the new engine."

Nodding, Director Bai agreed with Yang Hui's suggestion, and Director Bai, who had made up his mind, threw aside the original English design specification in his hand, and took out a pile of materials from the box next to him, and introduced the source of these materials by the way.

"These are the British design specifications translated by the Hongqi factory, and the Hongqi factory is still continuing to do localization work after the turbofan is launched, and there is no money in the hardware to continue, so they chose to start with the design specifications on the soft power, and now these are the achievements of the Hongqi factory."

Yang Hui also walked to the side of the wooden box, the box was wooden, but a layer of oiled paper wrapped the information well, and inside the oiled paper was a layer of kraft paper, and then a box of materials.

Yang Hui also took out a piece of information, and at first glance it was all a work notebook, and the words didn't look good, but it was very clear, and the translation was also very accurate, and it could be seen that it was translated with absolute care.

Translating design specifications is definitely a huge project, and this large box of materials is definitely quite valuable, which is the spirit of Hongqi Factory not to give up.

Solemnly put the information in the box, for fear that he would ruin the brainchild of these Hongqi factories if he was not careful: "Director, this Hongqi factory will not sink because of the turbofan nine dismounts, these materials are their proof, and we should return these materials to the Hongqi Factory intact when we use them up in the future." ”

The boxes were sealed again, ready to be carried out, and these brainchildren of the Red Flag Factory would be carried over in another form in the hands of the base.

"That's right, the Hongqi factory will definitely not sink, I believe that after this time, the Hongqi factory will be reborn, so we will hand over the first-stage fan to the Hongqi factory for production, and they need help at a critical moment." (To be continued.) )
