The advanced push core machine is a node that is difficult to bypass in all of Yang Hui's plans, and the performance data of the current push core machine is probably taken out, which is inferior to the fourth generation of the push core machine, but it is enough to plan to expand.

"Then Chief Engineer Liu can preliminarily estimate the test progress of this core machine, I believe that with the previous pre-researched technical foreshadowing, to quickly test the core machine, and improve the problems exposed in the test, the 624 Institute will definitely be able to do it."

At this time, it shows another advantage that can not be ignored in the pre-research of various technologies before the development of a launch, and only by deeply understanding the advantages and disadvantages of each subsystem and the performance can we be handy in the overall design improvement.

Careful people can find that the time required for the Republic to imitate a foreign aero engine is actually not a lot at all, according to the physical mapping in hand, although it is possible to quickly come up with 'Chengping', but this kind of thing is only a form and not a god.

Sophisticated industrial equipment, there is no exact same industrial manufacturing base, and various problems will continue to appear in the test after imitation, and then they can only be adapted around these problems, such an experience is vividly reflected in the Taihang engine of the Republic.

As the imitation engine was tested, the problem was exposed, the modification was retested, and the cycle continued until the engine was finally activated, and the actual time was not much different from developing an aeronautical engine from scratch, or even exceeded.

Chief Engineer Liu is very clear about the core machine developed by himself, and it can be said that the entire core machine can be identified with his eyes closed, and the use and location of each part can be clearly distinguished

It's not just about how the core machine is designed. I understand better why I designed it this way, and only after I am familiar with the problem. In order to be confident, we must say when the test and finalization of the core machine can be completed.

Chief Engineer Liu said with experience: "Don't worry about it. Judging from the current progress, this core machine will not have too big design problems, and the current supporting test equipment is also in place, and the tests can start step by step, I think it will be finalized and delivered at the latest at the beginning of 89. ”

From the beginning of the detailed engineering design of the core machine, to the first full-power high-altitude platform simulation test, it has been nearly a year to calculate, and it will take another year to do detailed testing and improvement, which is completely acceptable to Southwest Science and Industry.

It took nearly three years to complete the engineering design and finalization of a core machine. Although the design of the core engine is demanding, this is only a part of the system of an aero engine, and it must be developed faster.

On this point, Yang Huibiao agrees very much: "We can accept this time schedule, and Southwest Science and Industry is not too eager to manufacture and use this type of core machine on a large scale, as long as the data of this core machine can be delivered to our Southwest Science and Industry in the spring of next year." ”

There is no need to quickly finalize the core machine, this is because the current large channel is still pre-researching various technologies than civilian turbofans: gear reducer, large channel fan, just according to the pre-research progress. It was also necessary to start the engineering design of the whole machine in 88 years.

As for whether it will fall behind the progress of the engines of the other two competitors, Yang Hui can only look down slowly, and once again accept an aviation engine of the same level and put it in the list of MPC75 aircraft engine suppliers.

The law of the development of modern aero engines cannot be broken. At the same time, it can't be broken, instead of constantly anxiously waiting and urging, Yang Hui is more willing to design with sincerity. In the end, he came up with a better aero engine to defeat the competitors in a dignified manner.

Rely solely on commercial competition. Expecting competitors to be excluded from the game from the start is inherently unrealistic. It is also an insult and lack of confidence in one's own technology.

To say something unpleasant: I'm afraid that the current GM and Paul Red units have joined the MPC75 engine competition war, Xifei and MBB have long been happy in their hearts, and a mature system integrator will never limit their upstream suppliers to just one basket.

This is an indisputable fact, Yang Hui will never pin his hope of success on the mistakes of others, since knowing his competitors, Yang Hui has this plan to turn things around technically.

Hearing that the investor of the core machine and the follow-up user Southwest Science and Industry said that the requirements for the core development progress were not tight, which made everyone breathe a sigh of relief. The development of the entire core machine can have more time to be crafted, which will undoubtedly make the core machine more mature.

Only one core machine is mature enough to be widely reused, and it is best to blossom in all directions like the general GE9 core machine. In this way, these cooperative units that are widely involved in the development of the core machine will have a steady stream of orders in the future, and it is not in vain that everyone has invested heavily in this core machine for so many years.

"This can rest assured, we can complete the test in two months after the core machine working data, but I don't know when the high-temperature turbine can come up with a large-scale mass production product, and now we can't let go of our hands and feet in the test with such a few core machines!"

After talking about the good aspects, affirming the technical superiority of the core machine, it was the turn of Chief Engineer Liu to complain, there was no reliable high-temperature turbine blade to provide, and everyone always felt that something was wrong.

This also made Yang Hui feel very entangled, but the representative of the 625 Institute of Beihang 624 next to him said lightly.

"Or are you worried about the mass production of monocrystalline turbine blades? If you are not satisfied with the current progress, the 625 Institute can participate in the research of the current single crystal blade manufacturing process, as the Republic of China Aviation Precision Manufacturing Technology Technology Research Institute, the large-scale manufacturing of this turbine blade still has its own opinions. ”

Hearing that the original 625 had no sense of existence at this time, Yang Hui suddenly had a feeling of enlightenment, and now if you want to improve the yield of monocrystalline turbine blades in industrial production, what you need is not to make a breakthrough in the manufacturing process!

And in the study of this process, Yang Hui actually forgot that there is such a professional research institute in the Republic, which is really undeserved. If it weren't for the 625 Institute to remind me now, I'm afraid I would really be hanging on the road of 'self-reliance'.

Turning around and asking very formally, "So does the 625 Institute have any research on the manufacturing process of monocrystalline turbines?" China has never been exposed to these things before, and I don't think that the directional solidification alloy you developed can have much similarity to the single crystal manufacturing process, not to mention that the turbojet 14 high-temperature turbine you cooperated with Liyang back then did not have any results in the end. ”

To introduce 625 institutes to participate in the development of monocrystalline industrial production processes, Yang Hui of course has to test how much capacity these 624 institutes have, and whether they have dry goods. If you accidentally give a novice who also doesn't know anything, it will be a big loss, where did you get so much money to support the scientific researchers of 625.

must have felt a hint of disdain in Yang Hui's words, and the middle-aged man from the 625 Institute also came to the fire, as an old man who has studied in the field of high-temperature leaves for more than ten years, he is also the first batch of elites sent by the country to the United States for further study after the reform.

When most of his classmates stayed in the United States to enjoy themselves, he resolutely decided to return to China and continue the research on high-temperature turbine blade manufacturing in China.

"The manufacturing process of monocrystalline turbine blades is really difficult, but it is not impossible to break through, which can be done by our 625 institute, as long as the funds are put in place, everything is not a problem, I can guarantee that the bottleneck of large-scale production of monocrystalline blades will be solved within one year!"

is another madman who claims that as long as the funds are in place, he can come up with technology, Yang Hui doesn't know whether this is just crazy because of madness, or because this guy does have real materials to back him up.

With the idea of not letting go of the slightest opportunity, Yang Hui continued to have an in-depth conversation with this madman, hoping to get some information from this man's words that could show his skill level. (To be continued.) )
