Chapter 1221

No wonder these five words are so shocking. Supersonic cruise is one of the most important indicators of the next generation of combat aircraft. However, it is not easy to achieve this goal. In addition to making a disruptive breakthrough in the starting shape of aircraft, the key is the aircraft engine.

Not only the thrust should be large, but also the duration of the afterburner should be long.

In other words, this kind of engine is Tianjiang fierce man, not only to be strong but also to be lasting.

At present, there are only two ways to realize this kind of super power. One is the traditional technology school represented by Pratt Whitney's f-119 aero-engine, which is based on new materials and new technology and uses the traditional aero-engine architecture to achieve the so-called great miracle.

This technical route is mature and reliable, but the overall technical potential has reached a peak, so it is difficult to make a breakthrough.

Maybe it will make some achievements in the next generation of combat aircraft, but in the next generation of combat aircraft, it will have to face the embarrassment of being pushed back.

The other is the variable cycle system represented by the general F-120 aeroengine, that is to change the working mode of the engine according to different conditions, so as to achieve reliability, fuel saving and durability.

This technical route not only achieves unimaginable technical performance on the next generation combat aircraft, but also is the most feasible power solution for the next generation combat aircraft in the future.

Obviously, Tengfei group is following the general variable cycle plan. As for the goal, it's needless to say?

They not only aim at the power matching of the next generation of combat aircraft, but also include the next generation of combat aircraft. When they think of the upcoming China take-off, anyone with an IQ online can understand that China take-off is the backbone of the domestic aviation development.

Other aviation development plants either join in quickly to create brilliance together, or they are directly marginalized and have life and death!

As for how to choose, that is to say?

When Wang Erzhu and others finally understood the situation and began to figure out how to enter the new family of China's take-off in the best posture, the staff on the scene again took out the noise proof earmuff and distributed it to the people on the scene. Wang Erzhu took it over and took it with him. A moment later, the wd-490x engine started with Zhuang Jianye's signal, and then Zhuang Jianye came from the earmuff Our wd-490x adopts a variable cycle mode, with two built-in fan systems, i.e. the first stage fan in the front end and the second stage fan in the compressor in the front end of the core machine.

In the low power state of subsonic cruise, the wd-490x engine operates in the double bypass mode, that is, the turbofan mode. In the second season, there will be a pressure difference between the fan and the outer bypass, and more air will enter into the outer bypass, thus increasing the thrust.

Under the high power condition of supersonic cruise, the engine operates in the single bypass mode, that is, the turbojet mode. At this time, the positive fan cooling air pressure difference is maintained between the front and rear of the afterburner liner and the nozzle liner. At the same time, the pressure in the outer bypass increases until it exceeds the exhaust pressure of the second stage fan. Under the action of back pressure, the air is forced into the core engine, and a small amount of air is transported by the special engine It is used for afterburner, nozzle cooling and aircraft air entrainment

With Zhuang Jianye's description, the on-site staff manipulated the wd-490x engine to test the normal cruise state and afterburner cruise state. Looking at the actual figures on the screen, Wang Erzhu and others had to marvel. Tengfei group's technical strength in the aspect of aeroengine development is really unique in China.

Even if China's take-off is not established, they will certainly seize the responsibility of the domestic aviation industry in the future.

Fortunately, the monologue of Wang Erzhu and others was not known by the Aerospace Department. Otherwise, the people in the Aerospace Department had to point to Wang Erzhu and others by the nose and scold them: "you stupid geese who don't know the greatness of heaven and earth are still there. We have already surrendered. What is it to become a circular aero-engine? That's what you haven't seen in the hypersonic glider's high combustion turbine ramjet combined power. That's the pinnacle of the power field, black technology in black technology! "

Yes, the relevant enterprises and units of the Aerospace Department have long acquiesced to the establishment of China's take-off group on the basis of the take-off group. It's not that they don't want to compete with the aviation industry, but the key is that it's hard for them to be unconvinced with the things taken out by the take-off group.

The power system of variable cycle system is indeed the mainstream development direction in the future, but the key application field is not aeroengine, but hypersonic weapon system and aerospace aircraft in the future.

That is, high combustion power combination turbine.

Now, Tengfei group is the only one to carry out research in related fields in China and make considerable progress. There is no way to let others tap their potential in the aspect of reentry attack warhead of anti-ship ballistic missile over the years. This reentry warhead itself is a kind of hypersonic attack weapon.

Once this warhead is equipped with high combustion turbine ramjet power one day in the future, the attack power

For this reason, the Aerospace Department has long turned a blind eye to China's take-off. In any case, taking off group can't understand the rocket work for a while, and other aerospace departments can't understand the combined power of high combustion turbine and ram in a short time. In this case, the two sides are well water, so why hurt each other.Of course, if you don't look for trouble, you can't work with the Aerospace Department. You don't want to watch the excitement. Anyway, there are too many intersections between the aviation department and the Tengfei group. There are always some unconvinced enterprises and units that want to meet with each other. The air development field is the most active one, but now

"Ladies and gentlemen, I won't say anything. I'll make friends with you today..." After a brief introduction of wd-490x engine, Zhuang Jianye suddenly changed the subject: "there are still many imperfections in wd-490x engine. If you are willing to help, let's push forward this project together. If you think it's not suitable, it doesn't matter, you should make a friend!"

As a result, before he finished, Wang Erzhu immediately raised his hand to the sprinter who heard the starting gun and yelled, "Mr. Zhuang, you're out of the picture. Others don't know. Anyway, our XX factory is the first one to support you."

"And me ~ ~"

"our factory is also ~ ~"

"Mr. Zhuang, as long as you say a word, our factory will play wherever you point..."

Before Wang Erzhu's shouts came down, the shouts of the people in the hall came up one after another. It seemed that Zhuang Jianye was their leader and their leader. On the contrary, the deputy director standing in the corner became an embarrassed outsider, so that the person in charge of the aviation development plant didn't even bother to take care of him.

They are all people with a clear eye. The big guys behind them have made it clear for a long time. The Policy Department of aerospace development, where the deputy director general is in, will be integrated into the Commission of science, technology and industry for national defense, and will be merged with the power policy department of the Aerospace Department to form a comprehensive policy research department. Its main responsibility is to study and plan the development context of the domestic aerospace power system and related industrial supporting policies.

It can be regarded as a complete decoupling from enterprises.

No matter the money, no matter the people, no matter the power, who will give you a bird?

Naturally, the tea is cold before people leave.

Zhuang Jianye doesn't have the time to manage the state of affairs of the deputy director general. Today, he put forward a proposal to do internal integration. Now that the hard rock in the field of aviation development has been broken, it's easy to do the following things.

So one month after Zhuang Jianye received a person in charge of an aviation development plant, the word "China" was added in front of the big word "Tengfei group" in the headquarters building of Xingzhou Tengfei group. At the same time, the enterprise information of the industrial and commercial bureau also changed its name from Xingzhou Tengfei Aerospace Group Co., Ltd. to China Tengfei Group Co., Ltd!
