Hearing this shout, which was obviously filled with excitement and excitement, everyone looked towards the sky, and many people had already seen it.

It's a cobra maneuver!

The Cobra maneuver is a well-known over-stall maneuver that was first successfully flown by the Soviet Union's Su-27 fighter jet. In June 1989, at the Paris Air Show, the famous test pilot of the former Soviet Union, Viktor? Pugachev shocked the audience by performing a cobra maneuver in front of the whole world for the first time, so this maneuver is also known as the "Pugachev Cobra" maneuver.

During the maneuver, the pilot quickly pulls the rod back to tilt the nose to between 110 degrees ~ 120 degrees, forming a short level flight state with the tail in front and the nose in the back, and then pushes the nose and then returns to the original horizontal state. The speed at which the aircraft enters during the maneuver is about 425 km / h, and the plane decelerates at a rate of more than 148 km / h, and then decelerates to 110 km / h, this action only makes the aircraft bear an overload of 3.5~4g, and the flight altitude of the aircraft hardly changes during the whole maneuver.

Pretty!

It's so beautiful!

Feast one's eyes!

Seeing this wonderful cobra maneuver with their own eyes, many people's faces were full of joy and excitement, as if they had just completed a wonderful maneuver.

Vertical climb!

Sharp turn!

Drum maneuver!

Cobra Maneuver!

and a series of follow-up wonderful actions, such as breaking S maneuvering, looping catty buckets, inverted flights, tumbling and other wonderful actions, all of which were shown in front of them.

If it was before, it would have been really difficult for the J-10 fighter to complete this series of wonderful actions, and even if it could be completed, it would definitely not be so easy and exciting.

Quite a few people see the wonderful action of these series. It's just fascinating, it's so exciting, it's hard to come across such a feast for the eyes.

Li Tianfeng thought in his heart after watching this series of actions from beginning to end. Turbofan 20 engine, that's amazing!

In the high altitude, this J-10E completed these series of wonderful actions, and Major Liu began to ask for instructions on whether to return home.

After hearing the command center's order that "it is OK to return," Major Liu piloted the fighter plane and began to return home, and the fighter plane gradually lowered its altitude towards the airport runway and began to land.

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

For a long time, it was not until the fighter plane taxied smoothly on the runway and then completely stopped to command that the enthusiastic applause stopped.

Everyone through the glass. I could see a large group of people in the distance, running towards the fighter plane. This is the ground staff of the airport, the maintenance personnel, as well as the technical personnel of the aircraft factory and Tianfeng Technology Company, who must conduct a detailed inspection of the aircraft and engines at the first time.

The applause stopped.

Mr. Wei and Admiral Xu glanced at each other happily, and it could be seen. The two were very satisfied with the first flight just now, but they didn't expect that with the installation of the turbofan 20 engine, the maneuverability of the J-10 fighter was greatly improved, and so many wonderful actions were completed wonderfully and easily.

Admiral Xu said: "Mr. Wei." I didn't expect that our domestic turbofan 20 engine was so good, just now, I was a little stunned. ”

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

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

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

The two big leaders were talking happily and happily, 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 it is a big face, you see, Mr. Wei, how satisfied they are!" ”

Li Tianfeng looked at the faces of Mr. Wei and Admiral Xu, and couldn't help but smile happily, Li Tianfeng himself was very satisfied with the performance of the turbofan 20 engine just now.

Not long after, a colonel walked into the command center quickly, stood upright, saluted, and then said loudly: "Report to the chiefs, after a comprehensive and careful inspection, whether it is a J-10E fighter or a turbofan 20 engine, it is very normal, without the slightest problem or abnormality!" ”

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

The first flight of the turbofan 20 engine, the perfect performance, won the unanimous praise and praise of the military high-level, the military's internal newspaper, but also reported on the first flight, more military personnel know that there is such an excellent domestic engine.

The turbofan 20 engine, when it was in Tianfeng Technology Company, has completed a series of comprehensive test runs, including a comprehensive high-altitude platform test run, which has been fully tested and can be installed in a large area immediately.

Tianfeng Technology Co., Ltd. has made this preparation as early as possible, as early as the turbofan 20 engine completed the military acceptance review and obtained the production license, the turbofan 20 engine has entered mass production.

Now, the first batch of mass-produced turbofan 20 engines has begun to enter the final assembly and test run, and as long as the military places an order, it will soon be delivered to the military and equipped with J-10 fighters.

The turbofan 20 engine was fully considered when it was designed, even if it was the previous J-10 fighter, if the Russian-made engine was removed, it could be replaced with the turbofan 20 engine immediately, without changing the interface and installation size of the fighter engine compartment.

Orders from the military, of course there will be!

The turbofan 20 engine made a successful maiden flight and performed well, and Tianfeng Technology Company was once again commended by the military, and at the same time, the order was directly down.

Li Tianfeng personally went to the capital and signed the first batch of orders for turbofan 20 engines with the military.

A full 500 turbofan 20 engines!

Such a large number, it can be seen that the military likes and attaches importance to the turbofan 20 engine, perhaps, the J-10A, J-10B, J-10C and other fighters that were previously equipped with Russian-made engines may gradually be replaced with turbofan 20 engines.

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, which costs about 20 million US dollars and has an engine of 40 million yuan, is not expensive, at least cheaper than the Russian-made AL-31F engine.

The J-10 fighter, formerly a Chinese-made fuselage, Israeli electronics, Russian engines. Now, finally, a completely domestic turbofan 20 engine will be installed.

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

It's only May, this year alone, Tianfeng Technology Co., Ltd. has held orders with a total price of more than 90 billion, including more than 10 billion orders for Airbus 200 turbofan 16B engines, 43 billion orders for the military's spring order fair, more than 20 billion orders from COMAC, and this time, it is another order for 500 turbofan 20 engines.

The majority of employees of Tianfeng Technology Company were elated when they learned that Li Tianfeng had signed an order for 20 billion 500 turbofan 20 engines.

As you know, working in such a company has a great future.

The majority of front-line employees are like this, and the grassroots and middle-level managers of Tianfeng Technology Company are the same, full of energy, vitality and passion.

Top managers feel the same way in their hearts, but it is not shown on their faces, but in their work.

The company's work is carried out in an orderly, orderly and orderly manner, the management has reached a higher level, and scientific research and production have also made great strides.

In the office.

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

Sun Kangdao: "Tianfeng, I didn't expect that from 2009 to the present, in just a few years, we have made such great achievements, so that I will often think of what I used to look like in my hometown, when I opened a small mechanical processing factory, I never thought that there would be such an achievement today." ”

Li Tianfeng said: "Brother-in-law, our results are good, but in my opinion, we have just started, and we are still far from our ultimate goal." ”

It's still a long way off!

Sun Kang glanced at Li Tianfeng with admiration, Sun Kang knew Li Tianfeng's ultimate goal, and because he knew this, Sun Kang admired Li Tianfeng.

Sun Kang asked himself, if it were himself, he would definitely not dare to think like this. After glancing at Li Tianfeng with admiration, Sun Kang secretly said that it seems that he must continue to learn and improve.

With the development of Tianfeng Technology Company, Sun Kang realized that his undergraduate education level was not enough, and he began to study for an on-the-job master's degree.

Li Tianfeng knows that his brother-in-law is studying hard and trying to improve himself, Li Tianfeng is happy about this, a person who keeps learning must be a motivated person.

Since the beginning of this year, Li Tianfeng has only received so many orders in May, Li Tianfeng is satisfied, but there is also pressure, so Li Tianfeng said: "Brother-in-law, in terms of production, there is no pressure, 500 turbofan 20 engines, the military requires us to complete all deliveries this year." ”

Sun Kangdao: "With the smooth operation of the first phase of the Qingshi manufacturing base, the production pressure is not large, but the production capacity is basically full. ”

Li Tianfeng said: "Brother-in-law, it seems that on the one hand, we must pay close attention to the construction of the second phase of the Qingshi manufacturing base, and on the other hand, the scale of our company will be expanded again." ”

Sun Kang nodded, Sun Kang knew that Li Tianfeng began to prepare for the future development of the company, and the future Tianfeng Technology Company is not only in the field of aero engines.
