After a fierce exchange of information, just one day before Yang Hui left Brazil and returned to China, the general framework agreement of the entire cooperation was finally signed, and with this cooperation agreement, Yang Hui was able to return to China with more peace of mind.

And this time to see off the people than a few days ago to pick up even more people, this time the general manager of the Brazilian aviation industry is quite enthusiastic, first of all, the southwest science and industry is already one of the major shareholders of the embraer, must give the most basic courtesy, followed by the southwest science and industry this time for the 145 passenger aircraft to develop the turbofan engine, such a relationship to ensure that the general manager does not come is too abnormal.

"General Manager Yang, then we will see you at the Paris Air Show in a month, when we will announce the new 145 passenger aircraft development plan, if it is convenient, I still hope that Southwest Science and Industry will also announce the development of new supporting engines."

Hearing that Southwest Science and Industry announced the development project of a new small-thrust turbofan engine, Yang Hui also felt that it was not a big deal, and the small-thrust turbofan engine was indeed not a big problem for the current Southwest Science and Industry.

Don't look at the difficulty in the development of high-thrust turbofan engines, but when it comes to small-thrust turbofan engines, this kind of thing is much simpler in terms of materials and processing technology, otherwise there would not be the previous Japan crazy development of various small-thrust turbofan engines, that is, because Japan does not move high-thrust or even medium-thrust engines, and small-thrust turbofan engines can still be seen as long as they are willing.

Of course, the current Southwest Science and Industry has planetary gear transmission turbofan engine technology, as well as experience in developing CG-2000, turbofan 12 and other engines. The new turbofan engine will certainly not be a big problem to develop.

"Don't worry, we in Southwest Science and Industry have been developing supporting technologies for various aero engines for a long time. I have a lot of experience, and I can start the design of the core machine as soon as I go back. It is not out of the question that the Paris Air Show announced the news of R&D. ”

For this kind of small thrust turbofan engine, there is no need for Yang Hui to worry too much, after the 624 Institute completed the development of a new generation of medium push core machine, Chief Engineer Wu and Chief Engineer Liu found Yang Hui and mentioned whether they could continue to take the mode of medium thrust core machine, and the 624 Institute would contract some engineering design tasks.

At that time, the special situation was there, first of all, the domestic medium-thrust turbofan and high-thrust turbofan had already been approved, and it was certainly impossible for the state to fund the pre-development of technology, and the army also did not have spare money to do more projects. Southwest Science and Industry is rich. I even thought about working on a high-thrust turbofan project, but after some careful consideration, I gave up.

Repeated development of a turbofan engine of the same level as Taihang is definitely not possible, plus the current republic has a good relationship with the Soviet Union, the 31F engine has also entered the republic in advance, a country's army to ensure that the logistics of two sets of high-thrust turbofan engines have reached the level of the United States imperialism, if the southwest science and industry to complete a high-thrust turbofan, Yang Hui really can't think of any reason for the country and the army to support.

That is to say, if Southwest Science and Industry wants to develop a high-thrust turbofan engine, it will definitely not be a third-generation turbofan engine. The only possibility is to compete with the dawn side on the fourth-generation high-thrust turbofan engine, but when the fourth-generation turbofan engine is developed, I am afraid that it will not be possible to establish the project until after 2000, even if it is to be pre-researched in advance, it does not need to start at the end of the eighties.

In this way, there is a gap in the scientific research projects of 624 for a period of time. If there is no project to be done during this period, it will be a big blow to the scientific research capacity of the entire 624 Institute, for whatever reason. It is necessary for Southwest Science and Industry to help the 624 Institute tide over this difficulty, which is why Yang Hui gave part of the funds after pushing the core machine. It is necessary for the 624 Institute to pre-study the core engine of the small-thrust turbofan engine, and the funds required for the pre-research are not too much anyway.

As for now? Now that Brazil has given money for the development of new turbofans. Yang Hui will definitely not worry about money after returning to China, there are 624 coolies will naturally not let go, the development of the core machine or a professional unit to do more insurance, and from another point of view, the entire second institute has no extra energy to manage the development of the new small thrust turbofan core machine, and even the follow-up small thrust turbofan engine development work does not have to be carried out in the second institute.

"This can definitely be done, this year's Paris Air Show we Southwest Science and Industry will definitely not be absent, you can rest assured when the time comes."

For this year's Paris Air Show, Yang Hui really has no intention of letting go, after all, this is already 8.9 years, if this Paris Air Show does not seize the opportunity to brush up on a sense of existence, and then go to the aviation industry of Western countries to do the final exchanges, wait until the eight square events and then want to do some exchanges, all aspects will be greatly restricted.

With the take-off of the plane, it was only a week since the last time I went to Brazil, but it has been more than ten days since Yang Hui left Southwest Science and Industry.

"General Manager Yang, this time Southwest Science and Industry will also do in-depth cooperation with Brazil in the aero engine business, and this matter still needs to be reported in the imperial capital, and it will take about a few days. But don't worry, our Ministry of Foreign Affairs will definitely support this matter, and whoever wants to stop this project will have trouble with our Ministry of Foreign Affairs. ”

Listening to the words of the accompanying officials of the Ministry of Foreign Affairs of the country, Yang Hui was also a little surprised at first, when was the Ministry of Foreign Affairs able to work so cooperatively? I still feel a little uncomfortable, but I am relieved to remember that the nature of the Ministry of Foreign Affairs is a typical example of unreliable speech.

Yang Hui was reluctant to think more deeply, and he didn't take this to heart for the Ministry of Foreign Affairs. But he didn't know that this matter is really just like the Ministry of Foreign Affairs said, someone wants to destroy this project is absolutely impossible to get along with the Ministry of Foreign Affairs, this is a typical benchmark project, the Ministry of Foreign Affairs also hopes to rely on this project to give those foreign Kaizi who are waiting to see a shot in the arm, the only pity is that this plan is not as fast as changing, the international situation after the eight square incident

After some transfer and rushing, the plane landed at the Imperial Capital International Airport safely, and did not even stop and rest too much, and reported to the relevant units of the Imperial Capital again, although this small thrust turbofan engine has not been paid much attention in China, and this time it is still a civilian-grade turbofan engine developed. But this technique is more sensitive anyway. Feeling, Rao is Yang Hui personally ran the relevant units, and it took a lot of energy to run out of a rough idea, and the final result did not let a lot of hard work in vain, as long as the rules and regulations are done, the current republic wishes to have foreign capital injection to support domestic scientific research units.

The only thing that has some resistance is that the Science and Technology Commission, and even the military that got the news, put forward a request: the new turbofan engine project must not hinder the development progress of the turbofan 12, and everything must be the highest priority for the development of the turbofan 12.

"Don't worry, we are going to hand over the development of the core engine to the 624 Institute to do, and then we will probably put the whole machine development in Zhuzhou 331 Factory and 608 Institute to work together, their turbofan 11 engine will have a maximum of two years to finalize, and then it will be just enough to free up manpower, and these two engines are small thrust turbofan engines, or more suitable for there. The main scientific research team of our second institute must be the turbofan 12 and CG-2000. (To be continued.) )
