Chapter 2 Aero Engine Test

All the leadership of Hangfa Power came to the gate to welcome them in person!
Although the aviation engine has been reorganized, the Science and Industry Commission and other departments still have jurisdiction over the engine, otherwise the final assembly and testing of the "Everest Aero Engine" will not be placed on the engine, the original intention of reorganizing the engine, It is to allow Hangfa Power to develop better, go public for financing, and increase the vitality of the enterprise.

"Mr. Ye, welcome to inspect the work of Hangfa Power!" Mr. Liao, the chairman of Hangfa Power, led the leadership and greeted him at the gate in person.

Mr. Ye and Mr. Liao from the Science and Industry Committee shook hands: "To make a long story short, are you ready for work?"

Everyone is a busy person, and they came all the way from the capital, not just to exchange pleasantries.

This time around a hundred people, in addition to the Science and Industry Committee, there are also leaders and experts from the Ministry of Industry, the Ministry of Finance and other related departments. This is a matter of national defense, and the leaders are watching. If the board above is knocked down, no one can escape.

According to the design indicators, the "Everest aero-engine" is directly compared to the F119 aero-engine of the United States. The propulsion ratio will exceed ten and the maximum thrust will be 16 tons. This is a high-thrust aero-engine.Moreover, many advanced materials, cooling and aerodynamic technologies have been applied in the design of the Everest aero-engine. In particular, the advanced materials have been tested and demonstrated, and have been applied to the Taihang engine and the Kunlun engine.

However, the superiors place more hope on the Everest aero-engine, because for an aero-engine, the material is very important, but cooling and aerodynamics are also important. qualified engine.

In recent years, the Air Force has suffered from not having an advanced aero-engine. Even if they buy an aero-engine from Mao Xiong, they not only buy a monkey board, but also have various conditions attached.

Soon, everyone came to a factory building, and then saw an aero engine, Qin Yuanqing's eyes flashed, because Qin Yuanqing was very familiar with this aero engine, it was the F119 aero engine, or the Huaxia version of "Everest Aviation" engine'!
Although it took so long, such a prototype was finally produced.

The manufacturing cost of such a prototype is 400 million U.S. dollars, which is simply outrageously expensive. Rolls-Royce is not a problem in front of such an aero engine.

"Then let's start!" Mr. Ye of the Science and Industry Committee said in a deep voice.

Immediately, the person in charge of the experiment began to test, and as the aeroengine started, the aeroengine finally started to rotate.The three-stage fan initially combs and compresses the airflow, and finally divides it into two parts. The small part enters the outer duct, which not only acts as a cooling cut, but also provides some thrust at the end.

In addition, most of the air flow passes through the six-stage high-pressure compressor and is compressed again to meet the minimum required limit.Finally, the combustion chamber starts to ignite, the high-pressure air and fuel mixed into the combustion chamber are ignited, and the annular combustion chamber is instantly filled with flames in every corner.

The high-temperature gas with thousands of degrees Celsius flows through the high-pressure turbine, and after being rotated by the stator, it continues to flow through the low-pressure turbine, and the high-low pressure rotor begins to rotate rapidly.The hot gas is ejected through the tail nozzle to generate the maximum thrust of this engine.

For the new engine test, as long as it can run on its own and reach the predetermined thrust, it is fine.There is no need to do anything more now, just wait silently together.

Even the technicians who monitor the engine data don't need to do much, just monitor the operation data intently, not letting go of any details that were not expected.

But everyone was very excited. Just listening to the roar of the Everest aero-engine, everyone knew that this aero-engine was a proper high-thrust aero-engine.Thinking back to the Kunlun aero engine test and the Taihang aero engine test, the situation was frequent at the beginning, but the Everest aero engine has not had any problems so far, and the judgment was immediately judged.

The engine runs smoothly, and even the noise is under control. I have to say that this engine surpasses domestic engines in many aspects.

After running for a full hour, it stopped running.

There was a burst of applause at the scene, and the first test ran for an hour without any problems, which has already set many records.

"Academician Qin, congratulations. You have developed an excellent aero engine. On behalf of the country, I thank you! The motherland will never forget your contributions. I will ask for your credit when I return to Beijing!" Mr. Ye said excitedly.

The researchers who participated in the test at the Aero Engine Research Institute were all excited, cheering, hugging, and applauding. It is not enough to express their excitement.

During this period of time, they have also spent a lot of energy and time on this, and Mr. Ye has actually recognized their dedication by saying this.

"Mr. Ye, please wait for the completion of a series of tests and finalize the work!" Qin Yuan said with a light smile.

Today's test did not surprise him at all. After all, this is a mature aero engine. People in the United States have gone through a series of tests, and the F22 has been in mass production for ten years.

Others looked sideways at Qin Yuanqing's calmness. If it was them, they would cheer and be excited.

Then a group of people arrived at the meeting room, and then conducted the first test meeting, and the test data personnel reported the various data of this test meeting.

Of course, this is only the first stage, and there will be a lot of tests to test various data, such as thrust stability, thrust data, vortex front temperature, maximum temperature, etc., including the durability of the aero-engine, how many hours can it run stably , how long does it take to overhaul, etc.

The test before mass production is not just an aero engine, this process is actually a process of burning money.

If the entire test process can be completed within one year, it is already Amitabha.

Most of the personnel stayed behind, while Qin Yuanqing, Mr. Ye and other leaders left Hangfa Power and returned to the capital.

On the plane, Mr. Ye had recovered his calm. At this moment, he was already thinking about how to report to the leader, and at the same time adjusted some future plans.

Although the successful test flight of the J20 marks that China has become the second country in the world capable of developing and manufacturing fourth-generation stealth aircraft.But in fact, it will take a long time for the successful test flight to be officially installed in the troops. The original plan was that by 2016 to 2018, the domestically-made aero engines would be barely enough, and then the J20 fighters would be mass-produced and officially listed. Install troops.

It seems that the Everest aeroengine will solve the air force's heart disease problem. Once it is finalized and can be mass-produced, then the J20 can also be mass-produced and deployed to the troops in advance.

With the J20 fighter, the combat effectiveness of the Huaxia Air Force will be greatly improved, which can effectively defend China's airspace and deter the enemy's provocations.

There is no doubt that the leader will be very happy to hear the good news.

Qin Yuanqing looked at several other people discussing in a low voice, and was amused in his heart. The real data actually needs the entire test to be completed, and then some problems will break out during the entire test process, and then solve the problems.

It's too early to be happy now.

However, Qin Yuanqing also knew that Huaxia had no aviation engines for a long time. Before that, it had no ability to develop fighter jets.However, the J10 fighter was successfully developed, but it did not have its own domestically-made aeroengine, so that the J10 fighter could not be mass-produced. Up to now, the Air Force is still driving the second-generation aircraft. .

Yes, this is the current situation of the Huaxia Air Force. In the past, the foundation was too thin, there were so many places to protect, and the number of advanced fighters was not enough, so they could only make do with second-generation fighters.

Just like the sixth master of Hong Lu, he keeps improving, tinkering, and making do.This situation is not only the air force, but also the navy. Many warships belong to grandparents, and they are almost useless.

The more he learned, the more Qin Yuanqing felt a heavy sense of urgency. Today's Huaxia is at a critical moment. If he doesn't break through, he will be unable to go up or down, and it will be difficult to control his own destiny.And if you want to really develop and grow, you must achieve a technological breakthrough, otherwise the future will be very dangerous.

After experiencing a hundred years of humiliation, and after the founding of the People's Republic of China, China has experienced all kinds of difficulties and force. Huaxia is very clear and feels this strong sense of crisis. Without enough force, it is not enough to defend its homeland and interests.

You can't pin your fate on the kindness of others. This is a lesson learned by Huaxia at a huge price.

Therefore, even when the Republic was just born, it has been emphasizing that "friends have been here for a long time, and jackals have shotguns". It's all vain.

At this moment, several very slender stewardesses with sweet smiles cautiously came over to ask for an autograph. Qin Yuanqing showed a smile, signed his name, and wrote a line of blessings.

After going abroad, Qin Yuanqing felt that the quality of Huaxia's stewardesses was still very good, at least the service on the plane was very considerate, unlike the foreign stewardess, who had a bad attitude, it was as if the other party was a master.Moreover, the Chinese stewardesses are all very beautiful, at least they are good-looking, unlike many foreign stewardesses who are fat aunts.

Nowadays, Qin Yuanqing often encounters people who want to sign autographs wherever he goes. Although he is not a celebrity, he is better than a celebrity.

However, Qin Yuanqing hoped that it would be better if there were fewer such things. In fact, in the final analysis, he is not a celebrity, he is just an ordinary person.

At most, he is just engaged in scientific research, and everyone has a different division of labor, and there is no distinction between superior and inferior.
