Super military empire

Chapter 987 Can the J-10 without a vector engine be called the J-10?

"The front canard is laid out, there are side strips in the middle of the big ***, and the rear wing adopts the J-11 variable tail... The double vertical tails can be angled... The belly air intake is changed to both sides Intake..." Zhu Houdao pointed to the huge fighter plane in front of him and introduced it to the heads of the Military Commission, "Most of the appearance and aerodynamic layout are designed by Director Liu. Of course, Vice President Simon Love has made many changes to the design. It’s the air intake and the variable swept wing has been changed..."

The streamlined appearance of the J-10 is quite different from the J-11 that is copied from the F-14.

The nose part is a bit like the Su-27, which droops slightly, which can effectively improve the flight performance at high angles of attack, and at the same time coordinate with the front canard layout that can increase the lift on the runway.The big *** at the back and the variable tail at the rear are different from the f-14 and Su-27.

Liu Yijiu looked very satisfied.

However, Xia Fei did not think how good this plane could be.

"What kind of advanced performance can such an ugly appearance bring?" Although it looks smooth, the nose is drooping. This is very different from the J-11. It is not as pleasing as the J-11 looks.

There is a small delta wing in the front, and it is connected with a side strip wing to the big *** at the back, and the air inlet is in the middle.

"Chief, the performance of the fighter is not determined by the appearance!" Liu Yijiu rolled his eyes, knowing that Xia Fei said this was only because of anger in his heart, "What kind of advanced performance really has, you can only fly. I know it now!"

"Since we are going for the first flight, why haven't we gone to the airport to prepare?"

Long Yaohua took a look at Liu Yijiu, and there was indeed a big change. There was not much similarity with any fighter plane in the information. Under normal circumstances, the aerodynamic layout of countries around the world would not be so complicated.

China's technology is backward, can such a complicated aerodynamic layout greatly improve the performance of the fighter?

Seeing Liu Yijiu beckoning to himself, Zhu Houdao hurriedly explained, "The airport runway is ready. Just use a trailer to move the fighter plane to the airport runway..."

"The ground test is smoother than the J-11? This is a bit strange. The imitation did not encounter any major problems. As a result, our own brand-new design did not have any major problems..." Xia Fei felt a little strange.

Once again, a large number of three neatly arranged prototypes have been completed.

"Although the aerodynamic layout has changed a lot, so far, our engine uses the same turbofan-8 as the J-11, and the avionics system is the same..." Zhu Dadao arranged for technicians to start using it. The prototype of the test flight was transferred to the top of the airport runway while explaining.

There is a trailer in front of the fighter plane specially used to transfer the fighter plane to the hangar. Under the operation of the technicians, the fighter plane transfer is completely simpler than the previous test flight of the J-11.

The trailer is connected to the support rod of the front wheel of the fighter, and it is easy to tow the fighter with an empty weight of less than 20 tons.

Seeing the fighter plane slowly moving towards the gate, everyone began to become serious.

"Except for the change in the aerodynamic layout, there is no internal change. Isn't this the same as the J-11?" The other bigwigs are very difficult to understand. Is this the so-called pedigree in Liu Yijiu's mouth?

More importantly, since there is not much improvement, why would Liu Yijiu export the best technology?

Now the negotiations between the two sides have not been completely completed!

"Chief, you can't say that. These fighters are currently only prototypes. In the future, more changes will be made. We will equip the fighters with a vector engine with greater thrust and better performance, which is the turbofan under development- 10 engines; At the same time, the radar will use the active phased array radar that will be developed and formed, such as a multi-mode radar with stronger anti-interference; the internal fire control system will be more advanced, more powerful onboard computer system, multiple methods Aiming air combat mode..." Liu Yijiu couldn't help but speak at this time.

The more advanced the fighter, the more important the internal electronic system.

If it wasn't for the purpose of equipping the Air Force with a batch as soon as possible and not allowing the military leaders to equip the Air Force with the J-11, he would not do that.

"These configurations you mentioned don't seem to have been developed, right?" Xia Fei said to Liu Yijiu with a look of contempt.

Seeing Liu Yijiu deflated, Long Yaohua's face was filled with a smile.

Johnson was even more gloating.

They want to see how Liu Yijiu answers such questions.

Obviously, it only changed the external aerodynamic layout. It has to be said that this is a completely made fighter in China, which can enhance the pride and sense of honor of the entire nation.

"Really not. Active phased array, we have started to study many years ago, our gun aiming radar is used in this way, it is a little bit more mature to be applied to fighters, mainly high-powered. At that time there were power supply problems and heat dissipation problems...As for the engine, the turbofan eight is not very different from the turbofan six we use now. The biggest difference is that the turbofan-8 will have a vector nozzle at the tail..." Liu Yijiu introduced The real configuration of the J-10.

Now it's just to make the fighter fly, have more technology, and make the performance more advanced.

After the domestic technology develops and breakthroughs have been made in other areas, it can be replaced directly.

As the Soviet Union designed the same model as the Su-27, this can make the efficiency higher.

"Vector engine, what kind of technology is that, is it different from our current turbofan engine?" Regarding vector engine, the leaders of the Military Commission have not yet figured it out. thing.

Before imitating the f-14, even the second-generation fighters in China were not intact, and the research was thorough!

Of course, this second generation refers to the second generation of Western countries, which is already considered the third generation in the Soviet Union.

If you don’t know the third-generation fighters, you don’t know the performance requirements of the higher-performance fourth-generation fighters.

"The so-called vector engine is actually an engine whose nozzles can deflect in different directions to generate thrust in different directions. At that time, the main research direction of our engine next step!" Liu Yijiu briefly explained the role of the vector engine .

I don't intend to explain specific things at all, and even the designer Zhu Houdao and others don't know this kind of engine very well.

When Simon Love heard this, he looked at Liu Yijiu deeply.

In the Soviet Union, in the United States, this kind of engine is the top secret.

Where did the Chinese get the technology?

The fighter plane had already gone outside, and Liu Yijiu reminded the chiefs that they should go outside.

But Johnson obviously didn't intend to let him go through it like this. He felt that he, the director of the National Defense Science, Technology and Industry Commission, was very embarrassed. He didn't even know what a vector engine was. This is the first time I heard of it today.He immediately said to Liu Yijiu: "Comrade Xiao Liu, there is still a lot of preparation work on the runway before the first flight. You should give us a vector engine for popular science!"

Long Yaohua and the others also nodded, and Xia Fei even said while walking.

Liu Yijiu was helpless, and now Qi Hai and others were not here, so he could only explain it to the big guys.

Otherwise, should you tell the big guys to ask Du Niang for themselves?

But now, there is no such thing as Du Niang that is against the sky.

"Everyone should be aware that most airplanes in the world currently have relatively small angles of attack, and use higher flight speeds to allow the wings and tails of the airplane to generate enough lift for the airplane to take off. The disadvantage is that If you need a longer runway when the engine power is not strong enough... When the angle of attack of the aircraft gradually increases, the aircraft's tail will sink into the low-energy wake of the wing, causing the tail to stall, and the aircraft will spin and crash... …Our variable-angle tail is designed to solve this problem...Of course, a better situation is to use a vector engine that can rotate up and down or left and right, even if the aircraft exceeds the stall during flight At the elevation angle, the thrust direction of the engine can still be changed, and it can still provide lift to the aircraft, so that the aircraft has better performance..." As he walked, Liu Yijiu gave all the bigwigs popular science vector engines.

His explanation is more professional, and at the same time, it is easier to understand.

In addition to being equipped with more powerful turbofan engines, all kinds of fighters require very long runways to take off and land.

The vector engine can provide power in various directions, which not only shortens the take-off and landing distance, but also allows the aircraft to have a faster climb speed in the air, stronger maneuverability, and so on.

It even enables the fighter to provide yaw moment when it is about to cause a spin.

"What do you mean, what is the future engine of the J-10?" Xia Fei understood.

"This is not the case with future engines. If it were not for our air force's poor situation, the F-11 should be equipped with such engines from the beginning!" Liu Yijiu's attitude was very clear.

Only the J-10 equipped with a vector engine is a real J-10.

The f-14 does not have these properties at all.

"If the J-11 is equipped with such an engine, it can be done? Why have to waste more money and manpower to research new models?"

"The J-11 can be equipped with that kind of engine, but the aerodynamic layout has to be re-improved! No matter how it is changed, it will still be very similar to fighters from other countries. Why are we doing this?" The time has come to say this. The edge of an airport runway.

Liu Yijiu sighed when he saw the fighter gleaming in the sun not far away.
