Regarding the problem of fire after high-speed friction between titanium alloy impeller and casing, the project has been completed under Yang Hui's attention.

As for Yang Hui himself, he wanted to stay in this project for a while, hoping to make the results earlier, but in view of the intensive scientific research projects of Southwest Science and Industry at the same time, he really needs to put out fires and paste at any time.

After Yang Hui started the project here, it was less than a week, and he left without even seeing the titanium alloy impeller and casing used for testing. Before leaving, I had an exchange with Director Bai, and explained the pros and cons of the entire project, once again emphasizing the importance of the project.

He returned to the second institute and gave the invitation letter sent by the 8th International Aspirated Engine Conference to the chief designer of the turbofan 10 engine development.

"I hope that when Mr. Wen goes to the meeting, he will try to bring more young people to see, we need to train more young technicians, it is really a serious gap in our talents, and we must accelerate the training of the younger generation."

Yang Hui knows the importance of young people, and Chief Engineer Wen also knows: "Of course, I already have a plan in mind for this meeting, since the company is willing to give money for us to attend the meeting, I naturally want to consider young people more, a team of ten people, I will arrange at least seven young people to go, try to take care of and cultivate it!" ”

Readily agreed to Yang Hui's suggestion, at this time Mr. Wen showed his fox tail, and finally met Yang Hui, and now the funds that the entire company can take out for the research of non-state project technology are in the hands of Yang Hui, the general manager. Mr. Wen is now preparing to apply for a project.

pulled Yang Hui to the side, and took out the plan and put it in front of Yang Hui. It looked quite thick, and both Yang Hui were taken aback. This has to be a scientific research project, the plan is so thick, how much money must be invested to fill it.

Before reading this plan, Yang Hui silently calculated in his heart, how much money is still available for use, not that he doesn't know, but after doing the math, he found that there is really not much money.

Although Yang Hui has also obtained a lot of funds for the base in recent years, including the cost of transporting missiles that year, and the income from several foreign arms sales. There is also the windfall income of model aircraft in previous years. It seems like a lot, and the balabala added up to nearly a billion dollars in revenue.

Compared to revenue, there are also many projects that are consuming money. First of all, Southwest Science and Industry invested in the research and development of aluminum-lithium alloy and high-temperature single crystal; is swallowing money for the development of a new generation of core machine development plan; and the pre-research of the twin-engine fighter in cooperation with Northrop, and the YZ1 large side strip wing technology verification machine; Precision processing equipment purchased from various channels. These are projects that require an ongoing investment of money.

However, the L8 trainer now has an order confirmed by Egypt, and the first funding has been put in place, which is expected to support the development of the L8 trainer aircraft, which is the only project that does not need to be continuously invested.

There are a lot of big projects, and small projects are even more fragmented, and Yang Hui doesn't bother to list more, anyway, after a series of projects. At present, the only liquid capital left in the southwest is 20 million yuan, and 20 million US dollars in foreign exchange.

"We don't have much money now, if the project is too big, I will definitely not be able to approve it, I will look at the project specifically."

That's when I picked up the plan. After a cursory glance, he already had an idea for the project, and he could only comment on it in one sentence.

"This project is really necessary to be developed. But not now, our titanium alloy blade processing technology has not been fully mastered, and qualified materials have not been taken out. It is not necessary to improve the material of the blades of the high-pressure compressor of the turbofan 10 engine now. ”

The plan is a follow-up improvement plan for the turbofan 10 engine, which is to improve the blades of the high-pressure compressor and change the simple convergence tail nozzle to the convergent diffusion tail nozzle.

Two improvements. In Yang Hui's opinion, only the second one is necessary to continue, as for the first item, the compressor material will be changed to titanium alloy, which is really too luxurious, and it is originally an aircraft that relies on cost performance. There is no need to spend a lot of energy, money, and expensive titanium alloys for the engine.

Hearing that Yang Hui crossed out the most important item in the turbofan 10 engine improvement plan, Chief Wen was actually very reluctant, but after Yang Hui said the reason, he felt that it made sense.

After thinking about it, I listened to Yang Hui for the time being, just now I just rejected the improvement of compressor materials, and I haven't given an explanation for the second point.

"So, what about another measure of the well, the loss of the simple convergence tail nozzle we used is too great, and it is necessary to change to the convergence and diffusion tail nozzle, after overcoming this technology, our new engines can be used in the future."

Chief Master Wen looked like he was talking a little about the convergence diffusion tail nozzle, and Yang Hui stopped him in time.

"Needless to say, I know about the convergence and diffusion tail nozzle, and I started the pre-research very early, and now it is indeed time to advance this project to the engineering development stage, and I can still approve the money."

Although I didn't agree to all of my own projects, I still got a tail nozzle improvement, which is worth the trip, and after the new tail nozzle is used, the engine performance can be improved to a new level. If you can't increase the thrust to open source, it is also good to improve the tail nozzle and reduce unnecessary thrust loss to throttle.

Only then did Chief Master Wen let Yang Hui go satisfied, and took the approved slip, Chief Wen had already prepared to start the improvement of the turbofan 10 engine, so he had no time to care about Yang Hui.

And Yang Hui also came to the gear transmission project team led by his long-lost old colleague Zhong Jianjian, where Yang Hui saw a tired and energetic team. It is their bodies that are tired, and it is obvious that these researchers have not slept well for a long time, but they are still full of vitality and flying to do projects.

Silently walked to the side, filled the water bottle that had long since dried, and returned to the project team, Yang Hui called Zhong Jianjian, who was addicted to technology, out and asked about the progress of the project.

The news given by Zhong Jianshe made Yang Hui surprised and delighted, he really had a different harvest every time he came, and he continued to listen to Zhong Jianjian's introduction without saying anything.

"Therefore, the millions of dollars spent at that time were not a loss at all, not only did we get a lot of extremely excellent processing and design technology, which inspired us a lot for the planetary gear transmission reducer we are developing, but also allowed us to make a breakthrough in the gear reducer for turbo engines."

took out a variety of comparative data, and let Yang Hui see clearly the gap between the front and rear reducers, which is really a world of difference.

"I didn't expect ah, the original introduction of this set of gear transmission technology actually has this use, after the use of the new reducer, the performance of the turbo five engine has been so much improved, not only more reliable, the manufacturing cost can also be reduced so much, I'm afraid Zhuzhou factory is already happy, right?"

To have such a good thing, it is natural to make the engine manufacturer happy, but the reality is not happy for the Zhuzhou plant, and the improvement of the turbo five engine is not very beneficial to the Zhuzhou plant, and even the response of the Zhuzhou plant is very flat.

"Don't say it, now the Zhuzhou plant is really not interested in our new reducer, their turbo five engine has been produced very little, and most of the share has been handed over to Dongan Power. We have been asked to help improve the Turbo 6 engine. (To be continued.) )
