After witnessing the finalization and production of Jianjiao 7A, and unexpectedly seeing the quality control system implemented by the aerospace system at the base, Nie Shuai was absolutely assured of the quality of the products of the 0011 base.

Although he is old, but out of the importance of the national military front, Nie Shuai took a group of people to the car, and rushed to the second institute, this time in the finalized production of the Annihilation Sect 7A, the turbofan 10 was not installed as planned, and Nie Shuai was quite concerned.

In the car, he asked: "Yang Hui, the paper data of your turbofan 10 engine is very good, but now the progress of your engine development work is not as you said two years ago, and now the engine development work is now a serious drag on the Jianjiao 7A." ”

The engine development progress was delayed, and Yang Hui had no way to leapfrog from turbojet to turbofan, and at the same time, the national military standard had to be comprehensively revised, which was an unprecedented difficulty.

A series of new technologies can be overcome in three and a half years, which is absolutely quite remarkable, Yang Hui is not easy to explain too much now, the explanation is to cover up, and when I get to the base test center later, I see the development of the launch, everything is easy to say.

The convoy drove into the gate of the second institute and helped Nie Shuai get out of the car. There were no technicians lined up to welcome them, and there were just a few managers in the office, waiting silently under the scorching sun.

"This is our 0011 base No. 2, which is our new engine test center from the side, and the number of turbofan 10 engine tests is a height that all engines have not been able to reach before."

Looking at the fuel trucks lining up to transport fuel, pinching his fingers, he can almost understand how much fuel this engine swallows in a day. I have to admire how heroic this is.

Continuing towards the test center, the engine whistle became louder and louder. Even the air became hot, and the rich element of fire filled everyone's surroundings. It keeps penetrating into the skin.

Nie Shuai couldn't help but ask curiously: "How many engines have you put in the test?" ”

Yang Hui also proudly introduced, and took everyone to the side of the scrapped engine to put it in the warehouse, the few engines being tested in the test center did not indicate any problems in Yang Hui's view.

Only these scrapped test machines can silently tell how much test power was invested in the turbofan 10 engine, how much money was burned, and those engines lying quietly on the ground carried history.

Pushing them away, everyone was stunned, and the ground was densely packed with engines. Of all shapes and sizes. To put it mildly, this place should be called the engine graveyard.

"Hiss"

Everyone gasped, Prince Sultan didn't say a few words all the way, but now if he doesn't say no, the engine of this warehouse will shock Sultan deeply.

"There are so many tests and scraps in the development of an engine, and it is no wonder that few countries in the world can develop such a big country toy, which is a huge project and costs hundreds of millions of dollars."

The engines on the ground are intact, but there are also broken. The engine, which was violently destroyed during the test, broke through the double digits, and the engine casing shone an eerie blue when it worked in a high-temperature environment for a long time.

Clapping his hands, Yang Hui introduced the testing of these turbofan 10 engines in the past year.

"The core engine test run of the engine started last year. The core machine was tested for a total of 5,800 hours, and it was not until last month that the core machine was fully tested. And our engine test has accumulated 1800 hours. According to the plan, we will have a total of 25,000 hours of testing of our new engine. The remaining test items will take about 17,400 hours. ”

I don't know if I don't listen, but now I have listened to Yang Hui's introduction. Professionals naturally have their own comparisons in their minds, an engine is tested for 20,000 hours, what is the concept?

According to the current turbojet seven engine to make a comparison, the turbojet seven engine has been improved to the turbojet seven stage, and great improvements have been made in the afterburner, but the cumulative test operation has only been carried out for more than 3,000 hours, and the test time of the core engine of the turbofan 10 engine is not as long.

"Among the more than 20 engines on the ground, near the inside are the scrap products of the core engine of the turbofan 10 after testing. There are a total of 13 units, and some of them have not yet reached fatigue life, so we will do violence tests and scrap these core machines directly. The remaining engines are about to break through double digits. If the tests go ahead as planned, at least ten more scrapped engines will be added when the new engine is finalized. ”

A total of nearly 20 complete machines and 13 core machines will be invested, and it is expected to operate for 25,000 hours.

"Courage, with your tests, we will definitely be able to find problems at an early stage and develop a mature and reliable engine, which will be a great breakthrough for the Republic."

Nie Shuai is very excited, the country's aviation industry can narrow the gap with the international mainstream level in the most critical engine research and development link, so that the army's war eagle can have a strong heart, this is not worth rejoicing?

The new engine will be put into service in more than a year, which not only means that the J-7 series aircraft has a strong heart, but even the current J-8 is the same.

At this time, Nie Shuai finally understood why those guys in Fengtian kept jumping up and down in the center, but it turned out that this turbofan 10 engine actually performed well.

But the more this is the case, the more Nie Shuai can't let those speculators succeed, the new development is about to succeed, and now he has to share and eat it? How can it be

What's more, the development has not yet been completed, intense tests are underway, and it must not be interrupted by an executive order, never!

"You must work hard, develop this new engine well, prove your ability, and don't have a burden, you just have to bury your head in the project, I will carry the problems at the top level, and I will definitely not let you suffer."

Nie Shuai thought of the situation in the imperial capital, and now gave the 0011 base a reassuring pill in advance, lest there be a storm on it when there is a disturbance above.

There must be no distractions in the development of engines, and efforts must not be made without gains, and the vast number of scientific research personnel on the national defense science and technology front, as long as they devote themselves to scientific research, Nie Shuai must do a good job of protection.

But Yang Hui heard a different flavor here, 'high-level problem'?

Judging from this alone, Yang Hui could feel that the turbofan 10 engine should be involved in some whirlpool.

So what's going on? Why did the high-level have an interest in the turbofan 10, it seems that such an engine that involves foreign investment and also guarantees the use of three domestic aircraft, there will not be one who is full and wants to get off the horse, right?

Even the most stupid high-level people probably won't have this kind of thought, it should be in other aspects

Nie Shuai didn't pick out the details, Yang Hui naturally didn't dare to talk nonsense, maybe it's not too serious now, there is no need to let everyone know, hindering the development of the engine, Nie Shuai didn't shoot himself.

"What are you testing engines for? The test data must be remembered clearly, and the research must be careful and rigorous. ”

Nie Shuai also knows that this is the first time, and it will also be the last time he will go to the 0011 base, such a key unit must be carefully advised, this is Lao Shuai's hope for the national defense science and technology front.

Even if Nie Shuai came, the test center did not stop. Time is of the essence, and there are too many follow-up test items waiting to be released. If there is a problem in one link, the project that adopts concurrent engineering testing will be stuck as a whole, and the concurrent engineering flexibility of the base is not strong, and it is necessary to strictly follow the plan.

could only give a simple answer to Nie Shuai's entrustment, and immediately paid attention to the test situation again, and once again entered the realm of selflessness.

Seeing that the test center had a heavy task, Nie Shuai nodded and walked out of the test center with the group, waved his hand to disband the team, motioned for Yang Hui and Director Bai to follow, and went to the side office to say that there were some things that still had to be told to the leadership of the second institute.
