All kinds of situations in the ground battles in the bay area are not something that Southwest Science and Industry needs to care about, and after the imperial capital has done everything within the scope of its work, it has to prepare to pack up and go back to the company, and things over there are not easy.

Of course, during the period, I also met the technical personnel of the 170 factory who came to the imperial capital and the design team of the 603 Institute responsible for the six oil bombardment projects.

It was at this time that Guizhou, the base camp of southwest science and industry, was home to the largest aero-engine design unit in China: the Second Institute of United Aero Engine Company.

did not wait for Yang Hui to come back to participate in the first bench test of the turbofan 12 engine, the R&D team in order to be able to seize the time, this time chose not to make a big splash, so the first test run of the engine was only accompanied by technical personnel, and the first test run of the engine of this model began.

After decades of construction, especially after Yang Hui presided over the overall affairs of Southwest Science and Industry, the construction of basic test equipment in aero engines was spared no expense, and the new test center that expanded several circles was rarely stopped this time, and everyone was watching the first test run of the turbofan 12 engine

It is very safe, because the research and development path of the turbofan 12 is very formal, especially on the core machine, which has withstood various tests on the -2000 engine.

And it is also a military turbofan engine, the previously finalized turbofan 10 engine can still play a very good role in technology, plus the turbofan 12 engine early indicators have not reached the sky, and even in order to be able to reliably, safely and quickly develop the engine, even the most important thrust requirements have made some compromises.

In this case, if the research and development of the turbofan 12 engine is still bumpy, and there is no need for the military to express dissatisfaction, I am afraid that the design team will have to find a crack to get into.

Yang Hui did not participate in the first test bench diǎn fire, but it does not mean that it does not care about the research and development of this engine, on the contrary, this guy is waiting anxiously in front of the telephone, just waiting for the good news from the second institute.

The wait is long, but I don't know '⌒dǐng'⌒diǎn'⌒小'⌒ said, .2⌒3.∨os_(); How long had it been, and the phone on the desk finally rang, but it was half an hour earlier than expected.

There's no need to think too much about it now, just pick up the phone and ask about the situation. It was obvious that saliva was about to squirt onto the microphone, and the first sentence was.

"How's that, test ride smooth?"

After saying that, my heart began to hang, in case it was not good news to answer myself later, so what should I do? If there is a heavy design problem, will it affect the development progress of the engine, and even affect the progress of the J-18.

waited until the other side of the phone to hear the excited annunciation: "Shun lì, a qiē are very smooth lì!" Mr. Yang, don't you know, this time our S-4 turbofan engine table is very good, thanks to the support of the 420 factory, the second institute, and the three units in Liyang, we were able to design the S-4 turbofan engine so quickly, and complete the first bench test of the engine. ”

What? This model seems to have diǎn'er, isn't it, isn't it the annunciation of the turbofan 12 engine, why did it suddenly change to the S-4 engine? Although that thing is also going to be tested for the first time in the first half of this year, it won't collide with the turbofan 12 engine on the same day, right?

After being stunned for a long time, he shook his head, which was a little insufficient, and asked cautiously: "S-4 engine?" How did you bring forward its first test run to today, I think you gave the progress that seemed to wait until the end of April! What's going on now? ”

The next moment, there was a burst of laughter on the phone, and only after the general designer in charge of the S-4 engine laughed heartily did he explain the problem.

"Oh, General Manager Yang, you should also know, didn't you invite a lot of Soviet experts from the Ivchenko Design Bureau before? It is because these experienced experts have joined the design of the S-4, and many of the components we use are the -2000 engine fan ratio is reduced, although the efficiency is somewhat reduced, but it is enough to meet the basic needs, so now our S-4 engine uses some more mature technology. This time, there were Soviet experts to guide and check the gates, so our progress was advanced. ”

I really didn't expect that these technical experts from the Ivchenko Design Bureau really have a set, which directly speeds up the progress of the design and assembly stage by two months, and I really don't know when the final finalization can be advanced, which makes people feel a little looking forward to it!

Regardless, the acceleration of the project and the completion of the first bench tests are a great thing to be happy about.

On the phone, he did not hesitate to give a congratulatory speech, this S-4 engine can be regarded as a very important one in the Southwest Science and Industry Civil Development, maybe the engine profit time can directly exceed -2000, whether it is the thrust of the engine, or the 145 passenger aircraft project of Embraer, all aspects must be much smoother than the P-75 project, no matter how experienced the old driver.

"I'm doing business in the imperial capital now, and I can't get away from going to your side in person for the time being, so I ask you to help me bring the words. Let's just say: I, Yang Hui, sent a congratulatory telegram in the imperial capital, expressing my condolences to all the design, manufacturing, testing and other relevant personnel for their great efforts in the S-4 engine project, and expressing my gratitude to the Soviet experts from the Ivchenko Design Bureau, and of course, the vigorous cooperation of relevant fraternal units. I didn't make it to the bench test of the engine this time, but I will definitely personally celebrate you on the day it is finalized, and the head office will reward you one by one when the time comes. ”

Now I can't leave the imperial capital, and Yang Hui himself has no choice, so he can only verbally bring the words first, but the specific sentence is still that sentence, and when it is finalized, it must be rewarded heavily, after all, this thing is a civilian project, and there is no need to be too restrained when rewarding project personnel.

The other side of the phone obviously knew the situation: "I know this, I also called Manager Bai just now, and we also understand that Mr. Yang is not in the head office, isn't there no fanfare about the first bench test of the turbofan 12 over there?" There is no need for us to be more extravagant than a military project for a civilian project, but when the engine is finalized, General Manager Yang, don't forget the promise just now! ”

Yang Hui was a little dissatisfied with this: "This is not right, the first bench test run of a military project does not need to be publicized to the outside world, and even it needs a certain degree of secrecy. But your civilian engine project is different, the first thing to understand is: the importance of the project in your hands is no worse than that of military engines, and secondly, civilian engines cannot be kept secret, but you also need to publicize it with great fanfare, which is an engine to be sold to the civilian market. Listen to me, now spread the news of the successful first test run of the S-4, and the news will be brought to China, abroad, and Embraer. (To be continued.) )
