Even Qin Tao forgot when he said this, but judging from Mr. Song’s current appearance, it is obvious that he remembered his words in his heart. So, what happened to Mr. Song for most of the day today was this idea?

"Old Song, I am just a warship. I am an amateur in aircraft design. You are a professional aircraft designer. So, you must not listen to me! We have always said that we have practiced to find out whether our duck-style layout will destroy the stealth effect. It will only be possible to find out after experimenting!"

Qin Tao was a little helpless. Mr. Song had been struggling here for a long time. Could it be that he would not have experimented?

"Even if it will destroy stealth performance, we can make up for some of it through design. The biggest benefit of duck layout to us is that we can make up for our engine defects through aerodynamic layout." Qin Tao continued to analyze: "What you said is that if you want to build a twin-engine heavy air combat fighter, you need to benchmark with the F-22. We will not be able to reach the US level in the field of engines for a long time, so we must make up for it through excellent aerodynamic layout."

Old Song nodded.

The duck-style layout brings advantages in maneuverability. If the engine is not strong, it must be compensated by aerodynamics. This is also an important design idea for their J-10. Now, if we want to develop the next generation of air-control fighters, we have to use this idea. After all, the biggest problem with the duck-style layout is flight control, and they have already made all of them familiar.

"Mr. Qin, why didn't the vertical take-off and landing fighter designed by you consider the duck-style layout?" Mr. Song asked Qin Tao.

Qin Tao smiled helplessly: "When our project was launched, Project No. 10 had not yet flown for the first time. Our plane was just an improvement based on the Jacques-141. How could there be a complete change?"

These are all reasons. How could these technicians from the J-31A Design Department have high personnel levels? If they have a duck-like layout, their project will have to be delayed for at least five years.

He can't afford to wait. Such projects will easily get rid of after a long time, and customers will lose patience.

Moreover, Qin Tao is aiming at the mature F-35. He doesn't want to start a new job. Even the x-32 on the other side of the ocean starts to use a triangular wing layout, but in the end he has changed back to the conventional aerodynamic layout?

What we make is a moderate choice. Of course, this choice will inevitably lead to insufficient mobility. However, we have no intention of competing with enemy aircraft for mobility at all.

Mr. Song had already put down his burden and a smile appeared on his face: "Mr. Qin, what you meant just now is that you are optimistic about our project?"

"That's right, Mr. Song, our country is vast and we face many threats. Therefore, we must need dual-engine heavy air-control stealth fighter jets. I am optimistic about our 611 station and hope that we can release advanced fourth-generation heavy stealth aircraft in the future."

Mr. Song nodded: "Mr. Qin, thank you for your praise. We will work hard. However, it is said that my brothers have ideas as well."

Brother's unit?

Seeing Qin Tao's puzzled eyes, Mr. Song explained: "Mr. Qin, did you propose a change of stealth aircraft with Suhuoyin Design Bureau last time at the Defense Exhibition? The technicians from the Institute of 601 also heard it and they began to think about whether they could develop a stealth heavy fighter based on the Su-27."

What?

Qin Tao was indeed a little shocked.

He did propose this at the beginning. After all, Damao's stealth aircraft in later generations was this idea of ​​improvement, but this is definitely not the best choice. This is just another evidence that the Russians are relying on their old capital.

It is no longer possible to let the Russians develop a brand new fighter jet thoroughly. They can only repair and repair the Su-27 on the basis of the existing ones and use it as Su-57. Many of the useless designs will be inherited. Therefore, Qin Tao will not be optimistic about this imperfect design.

Moreover, more importantly, it is the design of the 601st Institute. As for the original design of the 601st Institute, it takes a long time to understand the original design of the 27th. It takes a long time to make them improve and improve.

Therefore, Mr. Song doesn't have to worry about competition at all.

"Old Song, even if the brothers have ideas, I will still support you." Qin Tao said, "You have the best design team and you will definitely be able to design the best fighter jet!"

Old Song nodded, his eyes full of anticipation.

"I don't know anything else, but it should be the most suitable one to use the turbofan 15 as the scheduled engine. When the design unit understands the original design and improves it, the performance will definitely be a big deal." Qin Tao also began to introduce: "The heavy fighter has enough volume to design large bullet bays. The main bullet bay must be able to carry six medium and long air-to-air missiles, and the side bomb bay must be able to carry two short-range air-to-air missiles."

Although when the J-20 opens the belly bomb bay when it is publicly displayed, there are four air-to-air missiles inside, if you look at the J-20 simulator, the location of the weapon is displayed, which is a mounting configuration of six medium-range bombs and two short-range bombs, and at least eight missiles can you go out to say hello to people.

In fact, at the beginning, the F-22 was also loaded with four AIm-120 missiles. Later, part of the wings was cut off and six were stuffed into it.

If you want more, you can only hang it outside, which will destroy the stealth appearance. You have to wait until the stealth-climbed missiles and stealth hangers appear in the future before you can plug in it. At that time, with the power performance of the fourth-generation aircraft, it is no problem to hang more than a dozen more.

Now, with Qin Tao's introduction, Mr. Song's eyes are gradually getting brighter. Mr. Qin just said that he is not familiar with the plane, but now, he is clearly very familiar!

This chapter is not over, please click on the next page to continue reading! Mr. Qin is really amazing!

After chatting, the basic aerodynamic appearance of the J-20 was actually revealed. The nose part is similar to the current J-31A, but it is larger in size. The bomb bay is still under the air intake duct. Two engines are stuffed in the back, and the double vertical tails are tilted outward.

The appearance of this aircraft is definitely much more domineering than the current J-10. With the modification of the Turbofan 15 as an engine, the power performance will also reach a new level. In this way, this fighter can really compete with the F-22.

"Mr. Qin, what do you think of the aircraft's loss nozzle?"

For normal fighter jets, the nozzles are fixed, and the engine can only jet backwards, and the maneuvering of the fighter jets is completely completed by the rudder surface.

But the fourth generation of the machine is different.

The American F-22 uses a baffle. From the back, its engine nozzle is not a chrysanthemum petal, but two movable baffles that can be adjusted through the baffle. It is quite simple, but it is not efficient. This method can only change the direction of the airflow up and down, which is also called a binary nozzle.

Although the old Russians did not have a fourth-generation machine, they already had an omnidirectional loss-of-volume nozzle. The structure of its circular nozzle is quite complex, with more than a dozen action cylinders that drive a large number of scale-like things. When it shakes its butt, the airflow emitted can be rotated and sprayed in all directions without any problem. This is also called a ternary nozzle.

If you compare performance, the latter is far better than the former. However, if you compare life, it is another situation. If you do so many hands and feet on the engine's heat flame, your lifespan is very low. The Su-30mKI provided by the Russians to A San, it is said that the lifespan is only fifteen hours. This is simply a scam. Even if you buy it, you dare not use it. You have to use it as a normal engine.

In fact, the vertical take-off and landing fighter currently under development can rotate the nozzle downward for more than 90 degrees, which is also an alternative loss-of-volume nozzle.

How to rotate the loss nozzle?

"It depends on our domestic research level." Qin Tao said: "Our duck-style layout is already very agile, so we can not use it for the time being. When the domestic scientific research level is reached in the future, we will create a suitable volume loss nozzle and replace it with the aircraft. The flight control can also reserve these."

With the loss nozzle, the maneuverability of the aircraft will be greatly improved, and flight control also needs to be adjusted accordingly. Fortunately, it is the era of telex flight control. If the previous hydraulic control was used, it would be impossible to complete the control tasks of so many rudder surfaces.

Qin Tao is an amateur, so of course he will not interfere with these specific detailed designs. To what extent domestic volume loss nozzle technology has developed, it will be possible to use corresponding volume loss nozzles. When the test flight was first tested, ordinary nozzles must be used.

"Mr. Qin, do you think our plane needs to be reserved for boarding the ship?" Mr. Song continued to ask.

This is related to Qin Tao. After all, he is a shipbuilder, and they are currently building aircraft carriers!

The carrier-based aircraft used on aircraft carriers must be the J-15 first, but this type of aircraft does not have stealth capabilities, so in the future, a stealth carrier-based fighter will definitely be needed.

So, should you consider it?

It is impossible for J-10 to board the ship because it uses air intake on the belly. This method has the highest flight efficiency at a large elevation angle, but it also faces the problem of insufficient strength. It is okay to take off normally, but it is absolutely impossible to withstand the impact force on the ship.

Now this twin-engine stealth heavy fighter uses the same nose design and air intake as the F-22. The front landing gear is also connected to the fuselage beam, so the strength is fine, so there is no need to worry about dragging the plane apart when ejected.

So, can J-20 be on the warship?

This is the most debated place among military fans in later generations.

Some people support it. After all, in later generations, J-20 is the only domestic fourth-generation carrier-based aircraft. Although the J-15 has strong performance, it has no stealth ability, so it is impossible for him to continue to serve for decades. While carrier-based aircraft in other countries are gradually entering the stealth era, J-15 is slowly falling behind.

So, who is the substitute?

The call for J-20 is very high, and I feel that domestic black ribbons must be put on the ship, which is to be satisfying.

There are many oppositions. For example, some people say that the size of the J-20 is too large, and this reason is actually untenable. The size of the J-20 is smaller than that of the J-15.

The total length of J-15 is 22.28 meters, with a wingspan of 15 meters, a maximum of 5.9 meters, and a maximum take-off weight of 32.5 tons. The total length of J-20 is 20.3 meters, with a wingspan of 12.88 meters, a maximum of 4.45 meters, and a maximum take-off weight of 39 tons.

As for the issue of folding the wings of the J-20, it is not a problem. A special folding mechanism can be installed on the outer edge of the rear wing. Even if it is not folded, it can be reduced by alternately positioning the wings of the French Rafale fighter, just like the French Rafale fighter.

The maximum take-off weight is a problem, but it is not a big problem. With the powerful electromagnetic catapult, coupled with the advantages of the J-20 engine and aerodynamic layout, there is no problem taking off on an aircraft carrier. If you land, it is impossible to come back in the sky. After you come back, the fuel consumption is almost done and your self-weight will be reduced.

However, in later generations, J-20 had almost never seen any images of the shipboard. There were many problems. It was not that Cheng Fei did not have this ability. The biggest problem was that the J-20 was low. Even if the pulsating production line was used, there were only thirty or forty aircraft a year. Later, in order to increase the production of J-20, Cheng Fei directly handed over the production of J-20 to Guifei, specializing in the production of J-20.

Before Qin Tao traveled, the domestic J-20 was equipped with dozens to more than 100 aircraft. It was not enough for the huge air force and was too short to be satisfied. How could the air force be used for the navy?

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! So the Navy could only pinch his nose and continue to buy the J-15, which is more expensive than the J-20. Chen Fei also felt the imminent pressure. When the stealth aircraft era was in the era of stealth aircraft, would they become OEMs after the Su-27 and its derivative aircraft were discontinued? They were also anxious and developed the J-31 project and made a stimulus to board the ship, but the Navy never made a statement.

What about now?

If the J-10 completes all the test flight subjects, Mr. Song will lead a team to build the J-20. Maybe in the next ten years, the J-20 will be produced, and the production will gradually increase. Does the Navy need the J-20 to be a stealth aircraft?

Qin Tao was thinking about these questions in his mind, and seeing that Qin Tao did not answer, the hope in Old Song's eyes gradually turned into doubt.

"Mr. Qin, are we asking too many questions? If our J-20 needs to take into account the needs of boarding the ship, it will form a competitive relationship with your J-31A..."

Mr. Song's words pulled Qin Tao's thoughts back, and the words were transmitted in his mind for another second or two before reaching Qin Tao's brain. He immediately smiled and shook his head.

"Of course not." Qin Tao said: "Our J-31A started from the design stage and took the path of international cooperation, which means that the performance of our aircraft will be well-known to the outside world. Such an aircraft is no longer confidential. Therefore, if our domestic army is hungry and purchases a batch, we are of course welcome, but if the army has concerns, it will not purchase in large quantities."

At the beginning, there was no capital in China, and if you wanted to create such an aircraft, you could only use a business model. The Navy and Air Force could not complain, and the performance was known to the outside world. Therefore, even if the Navy and Air Force had equipment, it was probably impossible to have a large batch of equipment.

This aircraft is an introduction. Through the development of this aircraft, domestic military aircraft will take a new step. All high-thrust engines, phased array radars, and stealth coating technologies will enter the fast lane through the development of this aircraft, which will provide opportunities for the development of other domestic stealth aircraft.

Even if it focuses on arms sales, it is beneficial. arms sales are never separate. Through the sales of this aircraft, many countries can be brought into the Eastern camp. Even if they do not express their support clearly, at least they will not be in the same circle with those conspirators.

"We expect that the vertical take-off and landing version may be suitable for the Navy's needs. After that, the Navy has a large number of amphibious assault ships, and will inevitably choose our vertical take-off and landing version, conventional catapult version, and land-based fighter version. The domestic market should not be big."

Mr. Song's eyes showed another light of hope: "Mr. Qin, what do you mean is that the Navy may choose our plane?"

"I don't know this. I just made an objective analysis. I think that as the maritime situation gradually deteriorates in the future, the Navy should need heavy twin-engine stealth fighters."

What will the future look like?

The old American navy will be equipped with JSF fighter jets. It is not known which one will eventually succeed. This fighter jet will also be equipped on aircraft carriers in other countries and show off its power.

Where is our side?

If our side loads the J-20, will the American veteran cry and shout unfair?

It was really pleasing to think of the scene where the bulky fat electrics were knocked down one after another!

The F-22 is just a land-based fighter, and the production line is closed. The United States has nothing else to do, so it can only rely on JSF to conquer the world. It’s okay to bully the third-generation aircraft, but you have to kneel in front of the black ribbon!

"Mr. Qin, Mr. Qin?" Mr. Song became curious again. Why is Mr. Qin always absent-minded today? What are he thinking?

"Well. Mr. Song, I don't think you need to think too much about the issue of J-20 being shipped. At present, the first thing to do is to do is to make land-based fighters. After all, the American F-22 is also a land-based fighter, and the air force's market is also the largest. When the time comes, it will be right, and then transform it into a carrier-based aircraft."

For land-based modification of carrier-based carriers, it is definitely necessary to increase weight. Under the current circumstances, it is most appropriate to first develop a land-based air-optimal fighter. In the future, for example, if a new engine is developed, the weight reduction and thrust increase can just offset the weight gain problem of modified carrier-based aircraft.

This sentence should be very ordinary, but Mr. Song opened his eyes widened: "J-20? What is J-20? Is it the aircraft we just mentioned?"

Qin Tao said he let it go again, why did he tell the model?

However, since you have said it, you can only continue to talk nonsense.

"Yes, that's it."

"But our model has just reached J-15! J-14 is still vacant."
