Chapter 208 Aviation Engine Testing

All the leaders of Hangfa Power came to the gate to greet us in person!

Although the aircraft engine power has been reorganized, the Science and Technology Commission and other departments still have jurisdiction over the aircraft engine power. Otherwise, the final assembly and testing of the 'Everest aeroengine' would not be placed in the aircraft engine power. The original intention of reorganizing the aircraft engine power,

The purpose is to enable Hangfa Dynamics to develop better, go public for financing, and increase the vitality of the enterprise.

"Mr. Ye, welcome to Hangfa Power to inspect our work!" Mr. Liao, the chairman of Hangfa Power, led the leadership to personally greet him at the gate.

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

We are all very busy people, and we have come all the way from the capital, not just for small talk.

This time there are over a hundred people, in addition to the Science and Technology Commission, there are also leaders and experts from the Ministry of Industry, the Ministry of Finance and other relevant departments. This is a major matter related to national defense, and the leaders are watching. No one dares to be careless, otherwise

If the board above is knocked down, no one can escape.

According to the design indicators, the "Everest Aero Engine" is directly benchmarked against the American F119 aero engine. The thrust ratio will exceed 10 and the maximum thrust is 16 tons. This is a high-thrust aero engine. Moreover, the Everest Aero Engine has applied many technologies in its design.

Advanced materials, cooling and aerodynamic technologies, especially advanced materials, have been tested and verified and have begun to be used in Taihang and Kunlun engines.

But the superiors place more hope on the Everest aeroengine, because for an aeroengine, materials are very important, but cooling and aerodynamics are also important. The superiors do not know that after solving the material problem, the Taihang engine or the Kunlun engine will immediately become an aeroengine.

A qualified engine.

In recent years, the Air Force has been suffering from not having an advanced aero engine. Even if it purchases an aero engine from Mao Xiong, not only will it buy a monkey board, but it will also come with various conditions.

Soon, everyone came to a factory and saw an aero engine. Qin Yuanqing's eyes flashed with light, because Qin Yuanqing was very familiar with this aero engine. It was the F119 aero engine, or the Chinese version of Everest Aviation.

engine'!

Although it took such a long time, such a prototype was finally produced.

The manufacturing cost of such a prototype is 4 million US dollars, which is simply ridiculously expensive. Even a Rolls-Royce is nothing compared to such an aero engine.

"Then let's get started!" Mr. Ye of the Science and Technology Committee said solemnly.

Immediately the person in charge of the experiment began to conduct tests. As the aero engine started, the aero engine finally began to rotate. The three-stage fan initially sorted and compressed the air flow, and finally divided it into two parts. A small part entered the outer duct, which not only acted as a cooling

cutting effect, and at the same time, it can also provide some thrust in the end.

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

Every corner.

High-temperature gas of thousands of degrees Celsius flows through the high-pressure turbine, and after the stator is turned, continues to flow through the low-pressure turbine, and the high- and low-pressure rotors begin to rotate rapidly. The hot gas is ejected through the tail nozzle, generating 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 will be fine. There is no need to do anything more now, just wait silently together.

Even the technicians who monitor the engine data do not need to do anything more. They monitor the operating data intently and do not miss any detail that is not expected.

But everyone's heart was very excited. Just listening to the roar of the Everest aircraft engine, everyone knew that this aircraft engine was a high-thrust aircraft engine. Thinking again of the Kunlun aircraft engine test and the Taihang aircraft engine test at the beginning.

The situation occurs frequently, but the Everest aircraft engine has not had any problems so far, so the decision was made immediately.

The engine runs smoothly and even the noise is under control. It has to be said that this engine surpasses domestic engines in many aspects.

After running for a full hour, it stopped running.

The scene immediately burst into warm applause. The first test ran for one hour without any problems. This has set multiple records.

"Academician Qin, congratulations to you for developing an excellent aero-engine. I would like to thank you on behalf of the country! The motherland will never forget your contribution. I will take credit for you when I return to Beijing!" Mr. Ye said excitedly.

The researchers at the Aero Engine Research Institute who participated in the test were all excited, cheering, hugging, and applauding, but nothing else could express their excitement.

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

"Mr. Ye, please wait until a series of tests are completed and finalized before you take credit!" Qin Yuanqing said with a smile.

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

Others looked at Qin Yuanqing's calmness and raised eyebrows. If it were them, they would have cheered and been excited.

Then a group of people arrived at the conference room and held the first test meeting. The data testing personnel reported the various data of this test meeting.

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

, how long will it take for overhaul, etc.

Testing before finalization and mass production is not just about an aero engine. This process is actually a costly process.

If the entire testing process can be completed within one year, that would be great.

Most of the personnel stayed, while Qin Yuanqing and Mr. Ye and other leaders left the aircraft engine and returned to the capital.

On the plane, Mr. Ye had regained his composure. At this time, he was already thinking about how to report to the leadership, and at the same time, he was also making adjustments to 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. However, in fact, it will take a long time for the test flight to be officially installed in the army. The original plan

, from 2016 to 2018, the domestically produced aviation engines will be barely sufficient, and then the J20 fighter jets will be mass-produced and officially installed in the army.

It seems that the Everest aircraft engine will solve the heart disease problem of the Air Force. Once it is finalized and can be mass-produced, the J20 can also be mass-produced and installed in the troops in advance.

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

There is no doubt that the leaders will be very happy when they hear the good news.

Qin Yuanqing looked at several other people discussing in low voices and felt funny in his heart. The real data actually requires the entire test to be completed, and then during the entire test process, some problems will break out and then be solved.

It's too early to be happy now.

However, Qin Yuanqing also knew that China had not had an aircraft engine for a long time. In the past, it did not have the ability to develop fighter aircraft, and it was just a little bit close, because there was no way. However, the J10 fighter plane was successfully developed, but it did not have its own domestic aerospace engine, so that the J10 fighter plane was unable to fly.

Large-scale mass production, the Air Force is still operating second-generation aircraft, and when performing missions, it is even prepared to collide with enemy aircraft and kill them both.

Yes, this is the current situation of the Chinese 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. They could only make do with second-generation aircraft.

Just like the sixth master of H-6, he keeps improving, tinkering, and making do. This situation is not only for the air force, but also for the navy. Many warships belong to the grandfather's generation and are almost useless.

The more they understood, the more Qin, Yuan and Qing had a heavy sense of urgency. Today, China is at a critical moment. If it does not make a breakthrough, it will be unable to move up or down, and it will be difficult to control its own destiny. And if it wants to truly develop and grow

, we must achieve technological breakthroughs, otherwise the future will be very dangerous.

As a country that has experienced a hundred years of humiliation, and even experienced various difficulties and force after the founding of the People's Republic of China, China knows very well and feels this strong sense of crisis. Without enough force, it is simply not enough to defend its homeland and interests.

You cannot place your destiny on the kindness of others. This is a lesson that China has learned at great cost.

Therefore, even when the Republic was just born, it has always been emphasized that "it takes a long time for friends to come, and shotguns for wolves" because destiny must be in one's own hands. Only a truly sovereign country can have true national dignity. Otherwise, everything will happen.

It's all false.

At this time, several very slim stewardesses with sweet smiles came over cautiously and wanted an autograph. Qin Yuanqing smiled, signed his name, and then wrote a line of blessing.

After going abroad, Qin Yuanqing felt that the quality of Chinese flight attendants was still very good. At least the service on the plane was very attentive, unlike foreign flight attendants who had a bad attitude and acted like they were uncles. Moreover, the Chinese flight attendants all looked very good.

She is beautiful, at least it is pleasing to the eye, unlike many foreign flight attendants who are fat aunts.

Nowadays, Qin Yuanqing often encounters people asking for autographs wherever he goes. Although he is not a star, he is still better than a star.

However, Qin Yuanqing hopes that there will be fewer such things. In fact, in the final analysis, he is not a star, he is just an ordinary person.

At most, he is just doing scientific research. Everyone's division of labor is different, and there is no distinction between superior and inferior.
