Hearing this shouting with obvious excitement and excitement, everyone looked into the sky one after another. After seeing this, many people had already seen it.

This is a cobra maneuver

Cobra maneuver is a famous stall maneuver, which was first successfully tested by the former Soviet Union Su27 fighter. In June 1989, at the Paris Air Show, the famous former Soviet Union test pilot Viktor Pugachev performed the cobra maneuver in front of the whole world for the first time, shocking the audience, so this maneuver action is also called the "Pugachev Cobra" maneuver.

During maneuvering, the pilot quickly pulls the rod backward and raises the nose up to between 110 degrees and 120 degrees, forming a short-term tail in front and the nose in the back, and then pushes the rod and presses the nose, and then returns to the original horizontal state. During maneuvering, the aircraft enters at a speed of about 425 kilometers and slows down at a rate of more than 148 kilometers and then slows down to 110 kilometers. This action only causes the aircraft to bear an overload of 35 to 4 grams. During the entire maneuvering process, the aircraft's flight altitude has almost no change.

pretty

So beautiful

Feast your eyes

Seeing this wonderful cobra maneuver with one's own eyes, many people had a strong look of joy and excitement on their faces, as if they had just completed the wonderful maneuvering action.

Vertical climb

Sharp turn

Roller motor

Cobra maneuver

And a series of exciting actions that followed, such as breaking S maneuvers, looping backwards, flying backwards, rolling and other exciting actions, were presented in front of you one by one.

If it were the past, it would be difficult for the J-10 fighter to complete this series of exciting moves. Even if it could be completed, it would definitely not be so easy and exciting.

Many people are fascinated by the wonderful actions of these series. It is so exciting. It is hard to encounter such a feast for the eyes.

Li Tianfeng, from beginning to end, watched this series of actions, thought to himself that the turbofan 20 engine was so powerful

In the sky, this J-10e completed these series of exciting actions. Major Liu began to ask for instructions on whether to return.

After hearing the command center that "can return" order, Major Liu drove the fighter plane to return, and the fighter plane faced the airport runway. The altitude gradually decreased and began to land.

In the huge command center, everyone stood up one after another, and no one mentioned it. Everyone applauded warmly and welcomed the return of the J-10e fighter jet with warm and long-lasting applause.

It took a long time until the fighter plane smoothly glided on the runway and then stopped completely to command, the warm applause stopped.

Through the glass, everyone could see a large group of people running towards the fighter plane. These are the ground crew members, maintenance personnel, and technicians of the aircraft manufacturer and Tianfeng Technology Company. Everyone must conduct detailed inspections of the aircraft and engines as soon as possible.

The applause stopped.

General Wei and General Xu looked at each other happily, and it can be seen that the two were very satisfied with the first flight just now, but they did not expect that with the turbofan 20 engine, the maneuverability of the J-10 fighter was greatly improved, and so many wonderful actions were completed brilliantly and easily.

General Xu said: "Mr. Wei, I didn't expect that our domestic turbofan 20 engine is so outstanding. Just now, I was a little shocked."

Mr. Wei also said happily: "The turbofan 20 engine is good, I am very satisfied."

General Xu nodded and said, "Mr. Wei, for such an excellent engine, we must quickly install and quickly improve the overall performance of our J-10 fighter jet."

Mr. Wei nodded and said, "I agree with this."

The two chiefs were having a happy and happy conversation, and Li Tianfeng and Zhang Haiping were also happy and talked together.

Zhang Haiping gave Li Tianfeng a thumbs up and said, "Mr. Li, the turbofan 20 engine has performed well. This time he showed his face. Look, Mr. Wei and the others are so satisfied."

Li Tianfeng looked at General Wei and General Xu and smiled happily. Li Tianfeng was very satisfied with the performance of the turbofan 20 engine just now.

Not long after, a colonel quickly walked into the command center, stood attentively, saluted, and said loudly: "Report to all the leaders, after a comprehensive and careful inspection, whether it is the J-10e fighter or the turbofan 20 engine, it is very normal, without any problems or abnormalities."

Hearing such a report, General Wei and General Xu nodded with satisfaction, and everyone in the command center applauded warmly.

The first flight of the turbofan 20 engine was perfectly performed and won unanimous praise and praise from senior military officials. The military's internal newspapers even reported on this first flight. More military personnel knew that there was such an excellent domestic engine.

The turbofan 20 engine has completed a series of comprehensive test runs at Tianfeng Technology Company, including comprehensive high-altitude platform test runs. After sufficient test runs, it can be immediately equipped with a large number of troops.

Tianfeng Technology Company made this preparation early. As early as the turbofan 20 engine completed the military acceptance and evaluation and obtained the production license, the turbofan 20 engine had already entered mass production.

Now, the first batch of mass-produced turbofan 20 engines have begun to be completed and tested. As long as the military places an order, it can be delivered to the military and installed with the J-10 fighter jet soon.

The turbofan 20 engine was designed with full consideration. Even for the previous J-10 fighter jets, if you remove the Russian engine, you can immediately replace the turbofan 20 engine, without changing the interface and installation size of the fighter engine compartment.

Of course, there will be orders from the military

The turbofan 20 engine successfully made its first flight and performed well. Tianfeng Technology Company was rewarded again by the military, and the order was directly dropped.

Li Tianfeng went to the capital in person and signed the first order for the turbofan 20 engine with the military.

A total of 500 turbofan 20 engines

Such a large number shows the military's preference and importance to the turbofan 20 engine. Perhaps, fighter jets such as the J-10a J-10b J-10, which were equipped with Russian-made engines, may gradually be replaced with the turbofan 20 engine.

The number is a gratifying 500 units, and the price is not low. The unit price is 40 million, Li Tianfeng is very satisfied.

The J-10 fighter jet costs about US$20 million and the engine is 40 million yuan, which is not expensive, at least cheaper than the Russian-made Al31 engine.

The J-10 fighter was previously made of Chinese fuselage, Israeli electronic equipment, and Russian engines. Now, it will finally be equipped with a completely domestic turbofan 20 engine.

After signing the order with the military, Li Tianfeng and his party returned to Tianfeng Technology Company. For the majority of employees, Li Tianfeng's trip to the capital brought shocking news to everyone, with 500 turbofan 20 engines and a large order of 20 billion yuan.

This is May. This year alone, Tianfeng Technology has already held orders with a total price of more than 90 billion, including orders of more than 10 billion for Airbus 200 turbofan 16b engines, orders of 43 billion for the military spring orders, and orders of more than 20 billion for COMAC. This time, there are orders of 500 turbofan 20 engines.

The employees of Tianfeng Technology Company were very excited to learn that Li Tianfeng had signed another order for 20 billion turbofan 20 engines. These days, there have been a heated discussion, and when talking about this matter, they are all full of surprises.

As we all know, working in such a company has great prospects.

This is the case for the majority of front-line employees, and the grassroots middle-level managers of Tianfeng Technology Company are the same, full of energy, full of vitality and passion.

Senior managers feel the same way in their hearts, but it is not reflected in their faces, but in their work.

The company's work is carried out in an orderly manner, orderly and in an orderly manner, with management to the level and scientific research and production also make great strides.

In the office.

Li Tianfeng and Sun Kang were chatting, because there was no third person, and they chatted while drinking tea, which was very relaxed.

Sun Kang said: "Tianfeng, I didn't expect that from 2009 to now, we have achieved such great achievements in just a few years that I often think of how I used to be in my hometown. When I opened a small machining factory, I never expected that I would achieve such achievements today."

Li Tianfeng said: "Brother-in-law, our grades are good, but in my opinion, we are just starting out and are still far from our final goal."

Still far apart

Sun Kang looked at Li Tianfeng with admiration. Sun Kang knew Li Tianfeng's ultimate goal. Because of this, Sun Kang admired Li Tianfeng.

Sun Kang asked himself that if it were him, he would definitely not dare to think so. After looking at Li Tianfeng with admiration, Sun Kang secretly said, "It seems that we must keep learning and improving."

Sun Kang is now studying for a master's degree. With the development of Tianfeng Technology Company, Sun Kang realized that his undergraduate education level was not enough and began to study for a master's degree. Now it seems that after completing this master's degree, he still has to study for a doctorate.

Li Tianfeng knew that his brother-in-law was working hard to improve himself. Li Tianfeng was happy that a person who kept learning must be an ambitious person.

Since the beginning of this year, Li Tianfeng has received so many orders in May. However, there is pressure. So Li Tianfeng said: "Brother-in-law, in terms of production, there is no pressure. The military requires us to complete all delivery this year."

Sun Kang said: "With the successful start of the first phase of the Qingshi Manufacturing Base, the production pressure is not great, but the production capacity is basically full."

Li Tianfeng said: "Brother-in-law, it seems that on the one hand, we must speed up the construction of the second phase of Qingshi Manufacturing Base, and on the other hand, our company will also expand again."

Sun Kang nodded. Sun Kang knew that Li Tianfeng had begun to prepare for the company's future development. Tianfeng Technology Company will not only be the field of aviation engines in the future.
