Reborn Technology Scholar

Chapter 219 2000 Hours Test

I don't know who took the lead in singing "Singing the Motherland".

Then it turned into a chorus, Qin Yuanqing also sang along, and Sa Beining also sang along, with tears in his eyes.

In the chorus, the recording of this episode of "Let's Talk" ended.

This "Let's Talk" is a recorded program, not a live broadcast. It will only be broadcast at the end of the month.

But the program team has also begun to warm up and strive to have a big satellite.

Qin Yuanqing finished the recording of "Let's Talk", declined the invitation from the program team, and went back home directly. He also had to prepare for the matters at hand and finish them so that he could go home and get married in peace.

Qin Yuanqing took some time to go to the aircraft engine because the Everest aircraft engine was about to undergo a 2,000-hour test. This time, our joint participation in the meeting will determine whether to mount the Everest aircraft engine on a fighter jet in advance for flight verification and evaluation.

It stands to reason that it takes a long time for an aerospace engine to go from research and development, testing, flight verification on a fighter jet to final mass production. After all, various problems will always arise during the testing phase, and then need to be solved, again and again.

Correction, just to test the aero engine, many units have to be manufactured.

It’s just that the Everest aircraft engine is too stable, so stable that it is nothing like a newly developed aircraft engine. It has been running without any problems so far. Some minor problems are caused by deviations in the manufacturing process.

Therefore, the military took the initiative to demonstrate the possibility of mounting it on fighter jets in advance, so as to speed up the finalization and mass production of the Everest aviation engine.

It’s not that the military is too anxious, there is really nothing they can do. The Taihang engine and the Kunlun engine are too weak. The Kunlun engine was originally positioned at the medium thrust level. Although the materials have been solved now, there are problems with the structural design itself. As a result

Although the new engine has solved many old problems, it still cannot meet the needs of the modern air force. The Taihang engine is a high-thrust turbofan engine, but solving the material problem does not mean solving all problems. When it was put on an aircraft, it turned out that there were problems in the air.

The engine stalled and the aircraft almost crashed, causing the military to really give up.

So we pinned our hopes on the Everest aircraft engine. At least the Everest aircraft engine has been tested for 2,000 hours without any problems. It seems to be relatively reliable.

When the entire team arrived at the aircraft engine, the Everest aircraft engine began its 2000th hour test. This is a key node. An aircraft engine can last for 2000 hours, which means that the aircraft engine can be mounted on fighter jets and has the conditions for use!

When the start-up was announced, the aircraft engine made a powerful roar. This roar made people's blood rush. Everyone could feel the power of this aircraft engine. The powerful thrust was enough to make a fighter plane take off.

It is conceivable that once the Everest aviation engine is mounted on the J20, how powerful the J20 will be.

When the 2,000-hour test ended, there was a sudden burst of applause to celebrate this historical moment. After all, it was not easy to complete the 2,000-hour operation test in just a few months. At least the Taihang Aviation Engine and the Kunlun Aviation Engine had been used for several years.

This milestone test has just been completed, which also means that the Everest aircraft engine has completed the journey of the Taihang aircraft engine and the Kunlun aircraft engine in a few months.

Subsequently, a meeting was held at Aero Engine, where the testers reported relevant data reports, as well as problems that had arisen so far during the test, summarizing and corresponding handling measures.

Testing is a very close thing, and the data tested by the testing team is extremely important.

"Academician Qin, you are the leader of the research and development of the Everest aviation engine and you know the most about the Everest aviation engine. What do you think about the Everest aviation engine being put on the aircraft for flight verification and evaluation!?" Relevant military leaders directly named Qin Yuanqing.

, I want to hear Qin Yuanqing’s opinion.

Unlike the Taihang aircraft engine and the Kunlun aircraft engine, the Everest aircraft engine still belongs to the Aeroengine Research Institute of Shuimu University, not the military or a research institute affiliated to the Commission of Science and Industry.

The person who knows the most about aero engines is Qin Yuanqing from the Aero Engine Research Institute of Shuimu University. The Aero Engine Research Institute of Shuimu University was also involved in the whole process.

Qin Yuanqing said with a smile: "There was no problem with the theory of this engine when we were studying it, and it can meet the requirements of fourth-generation aircraft. After this period of experimental verification, it shows that the performance of the Everest aviation engine meets the design requirements and its operation is very stable."

Yes, there is still a lot of room for improvement, and further improvements can be made on this basis.”

"From the current point of view, it can be carried out on fighter jets for flight verification and evaluation!" Qin Yuanqing is quite confident in the Everest aviation engine.

Although the Everest aircraft engine is not perfect, it can meet the current requirements for the development of the Air Force, and more powerful functions can be developed on this basis in the future. For example, Pratt & Whitney developed the F135 aircraft engine based on the F119. The F135

The aircraft engine is developed based on the core machine and main structure of the F119 engine. It has an afterburning thrust of more than 18 tons and a thrust-to-weight ratio of more than 10. The F-35B also uses the lift system of Rolls-Royce, making the aircraft capable of

Achieve short takeoff and vertical landing.

The number of parts of the F135 aero engine is about 40% less than that of the F119, but the performance has not been reduced much, thereby reducing the cost of the F35. Moreover, the F35 is a single-seat, single-engine fighter, and its performance is still very powerful.

However, all of this is improved, optimized, and developed on the basis of mastering the F119 aero engine, so the F119 aero engine is even more important.

Several leaders received Qin Yuanqing's affirmative answer and smiled on their faces. Other relevant experts also expressed their opinions one by one. Although some people raised objections and felt that this was too risky.

After all, a J20 costs almost 100 million U.S. dollars. Once the aircraft crashes and a person is killed, the loss will exceed 100 million U.S. dollars. The risk is too great.

Some experts also proposed that the J10 be equipped with the Everest aeroengine for testing, so that great risks can be avoided.

After all, the J10 is a medium-sized fighter jet with a relatively low cost. It only costs about 15 million US dollars, which is less than one-fifth of the cost of the J20. Once any unexpected situation occurs, the losses will be greatly reduced.

After considering everyone's opinions, the military chose to install the Everest aero engine on the J20 aircraft in advance for flight test evaluation.

Whether it is a horse or a mule, you have to take it out for a walk before you know it.

Chief Engineer Yang Wei also affirmed, saying that J20 will not disappoint everyone.

With the finalization of the Everest aircraft engine for flight test evaluation, Qin Yuanqing signed a Everest aircraft engine technology transfer agreement on behalf of the Aero Engine Research Institute, transferring the complete set of Everest aircraft engine technology to the military, and the Aero Engine Research Institute also obtained

After paying RMB 20 billion in technology buyout fees, the Aero Engine Research Institute will provide technical services in the future.

The technology buyout fee of 20 billion yuan seems to be a lot, but in fact it is not much. Pratt & Whitney itself has strong aero-engine technology research and development capabilities for F119 aero engine technology, and it still spent more than 20 billion U.S. dollars. And Taihang

The investment in research and development of engines and Kunlun engines is tens of billions.

Therefore, 20 billion is not too much.

The income of 20 billion yuan has also greatly eased the financial pressure of the Aero Engine Research Institute, and also made President Chen very happy. After all, Shuimu University also has shares. If this money is one cent, Shuimu University will have an income of nearly 10 billion.

"What!?" Qin Yuanqing had just returned to Shuimu University when Principal Chen came to visit him. He thought he had heard wrongly: "Principal, what did you say!?"

"Dividends!?"

"It's impossible to pay dividends! It's impossible to pay dividends in the next life!" Qin Yuanqing shook his head repeatedly and said: "I haven't even asked you to ask for the bonus from the institute, but instead you came to me to ask for dividends!"

Are you kidding me? The school is only responsible for paying the basic salary of faculty and staff. The rest is paid by the institute. Experimental instruments, office equipment, and test materials are all paid by the institute.

For making such great achievements, it stands to reason that the school should get a large amount of money to reward scientific researchers, but now it is paying attention to dividends!

What a joke!

It's impossible to kill him!

The joyful smile on Principal Chen's face suddenly froze, and then he explained the facts and said with sincerity: "Academician Qin, you also know that the school has big plans and great expenses, and the school doesn't have the money to buy it now.

A batch of books and a lot of equipment have been used for thirty or forty years, and there is still no money to replace them. Many professors have come to me to complain, saying that if the equipment is not replaced, they will not be able to conduct research, and there is no money left in the account.

It’s not useful!”

"Well, if you are not a family member, you don't know how expensive food, rice, oil and salt are. It is also difficult for me as a parent..." Principal Chen babbled a lot, which was very bitter.

Qin Yuanqing refused to agree to it!

Just kidding, he is not short of money now. There is a pile of money lying in his bank account. FAW has just sent him the money for the third quarter. He still has to think about how to spend the money. How can he possibly use the money from the Aero Engine Research Institute?

The money is distributed as dividends. You must know that dividends are subject to 20% personal tax.

As for the school being short of money, it’s none of his business, just find a way to fund it yourself!

Moreover, Qin Yuanqing did not believe that Shuimu University was short of money. This year, Shuimu University received 8.2 billion in educational funding, ranking first in the list. In addition, it also attracted a lot of sponsored scientific research funds, which amounted to tens of billions.

He did not forget that for every mobile phone sold by Warwick, a portion of the money would be given to Shuimu University. He was the one who really contributed a lot in this process, but in the end he did not get a penny and just took the salary from the school.

Damn, the donkeys in the production team are not so hard-working!

You didn't even ask for a bonus from the school, but asking for dividends from the sales of Warwick mobile phones is enough loyalty. You, Principal Chen, shamelessly target the research institute and want the school's dividends. You are thinking too much!
