Chapter 1022 04 Fighter-20

"Mr. Qin, are you here too?" Lei Zi looked at the people greeting him. When he spotted Qin Tao, he immediately shouted excitedly.

“Well, how is flying this plane different from our previous planes?”

"Twin-engine heavy-duty aircraft are real fighter jets." Lei Zi sighed with emotion: "When I used to fly single-engine fighter jets, I always felt that the thrust was not enough. Now, with a twin-engine heavy-duty aircraft, as long as you give a little more throttle, the aircraft will fly like a fighter jet. Like a roaring beast, this aircraft is highly maneuverable and easier to fly than the Su-27 series aircraft."

There are heavy-duty fighters in China, such as the Su-27 and its improved version. However, the Su-27 fighter only takes advantage of aerodynamic achievements such as slat wings and wing body fusion, and does not use canards that can make it more powerful. Advanced equipment that greatly improves the maneuverability of fighter planes.

Now, the aircraft in front of you is a master of aerodynamic design. All aerodynamic designs are used, and the effect is naturally different.

Qin Tao nodded. He was not a pilot and had never flown a fighter plane himself, but he could tell based on the pilot's description that when Delano came back, he would be satisfied with the aircraft.

Delano likes to fly heavy aircraft. After coming to the East, he flew on the J-15, a twin-engine heavy carrier-based aircraft. After that, there were four generations of stealth aircraft, which could defeat opponents with their stealth. Therefore, Germany Rano also likes to fly, especially since he can do many things with his stealth, including not being controlled by the bridge behind him.

 However, after all, this is a single-engine aircraft with insufficient power. Delano is not very satisfied with this. Now, with the aircraft in front of him, it can be said that everything is complete. It is both stealth and a fourth-generation heavy-duty aircraft.

"By the way, where's Zhao Dangsheng?" Wu Shengli looked on, feeling both happy and disappointed. He suddenly thought of this person.

Zhao Dangsheng was originally from the 611 Institute, but later Qin Tao was working on the fourth-generation stealth aircraft, so he was transferred to Lao Maozi. But later, when the fourth-generation heavy-duty aircraft was built here, he came back to help. Wu Shengli still remembers It is very clear that Zhao Dangsheng promised to help develop carrier-based aircraft.

“During the first flight, they came out to take a look, but after landing, they went back again,” Mr. Song said.

 At such an important moment, they actually didn’t come out to participate in the whole process, but just watched it during the first flight? Wu Shengli was very curious: "What are they doing?"

“We have a very heavy task to continue assembling prototypes. After all, the needs of the navy and air force are urgent.” Mr. Song said.

Wu Shengli's heart was suddenly filled with expectation: "Navy and air force? Are you helping us too?"

"Yes, the Navy has allocated R&D funds to us, and of course we must fulfill our commitment to the Navy." Mr. Song said: "The 04 sorties we are producing are carrier-based aircraft for the Navy."

“Then what are you waiting for? Let’s go take a look.” Wu Shengli couldn’t wait to say: “Let’s go, Tao Zi, let’s go there together!”

Although the first flight ceremony has ended, everyone must still adjust the aircraft based on the first flight data. Wu Shengli can't wait. He wants to see the navy model immediately.

"Let's go, I'll go with you." Mr. Lin smiled: "We've finished watching the first flight, and there's nothing to follow. Next, let's visit other prototypes that are being built."

 After a fighter aircraft is developed, it must be tested before flying. A large number of problems are exposed through test flights, and these problems must be continuously solved and improved.

Therefore, only one prototype is definitely not enough, a large number of prototypes are needed for test flight. When Lao Maozi's Su-27 was tested in the early years, more than a dozen experimental verification machines code-named T-10 were built.

 The East does not have that luxury, but it must be used enough.

The one taking off now is the first prototype built. This is also the basic practice in fighter research and development. The first aircraft has to fly for the first time. After all, this is the most important thing. First, see if it can fly into the sky. If you encounter The aircraft designers in Madaha may have miscalculated the lift and gravity, and the aircraft really couldn't fly.

The second aircraft is usually built at the same time as the first one. This aircraft will never fly in its life. After it is built, it will be put on a static test stand and withstand various pressures. Countless jacks will bear on it. , look at its ability to withstand pressure, so as to determine whether the stress frame of the aircraft is reasonable, where it needs to be strengthened, where weight can be reduced, and how many hours the aircraft body can last.

 The next 03 sorties, 04 sorties, etc. to be manufactured are all to be flown, but the focus is different. Some are specialized in aircraft bodies, some are specialized in avionics, some are specialized in missiles, etc.

 Among the subsequent aircraft built, one was developed for the navy. This is the 04 naval carrier-based aircraft!

 After talking to Zhao Dangsheng last time, the Navy allocated a sum of money. However, they did not know the development progress of 611. Unexpectedly, after these funds were put in place, 611 was already being developed for them!

 When Wu Shengli, Mr. Lin and others entered the large production workshop, they saw two fighter planes being assembled.

 The assembly progress is almost the same, but the assembled parts are obviously different, especially the nose landing gear that is being installed at this time.

 The two fighters installed parts almost simultaneously, so they can be compared.

 At the station of sortie 03, the nose landing gear installed was a single wheel with relatively small tires. The landing gear was also very slender and looked as thick as an arm.

 At the station of sortie 04, the front landing gear installed was a double wheel, and the two tires were installed side by side. The landing gear above was very thick and looked about the same as a thigh.

Just by looking at this comparison, you can tell who is the navy model.

Wu Shengli ran directly over and looked at the navy carrier-based aircraft of sortie 04.

“You have worked hard. It must have taken a lot of effort to develop carrier-based aircraft for our navy. This landing gear looks like...”

Before Wu Shengli finished speaking, Zhao Dangsheng interrupted him: "Leader Wu, this landing gear was transplanted from the J-5, with only minor changes. It didn't take much trouble."

Jian Fifteen! No wonder it looks so familiar! Wu Shengli had an awkward smile on his face, while Qin Tao was very emotional.

Can the J-20 be put on the ship? This Qin Tao is not sure, after all, he has never seen Qin Tao in his previous life. However, the J-20 can be compared with another heavy carrier-based aircraft, the J-15.

There are many voices and theories questioning the J-20. For example, the J-20 is too big!

Then you have to take a look, the J-15 is bigger than the J-20!

The J-15 has a fuselage length of 22.28 meters and a full wingspan of 15.0 meters. What about the J-20? The fuselage length is only 20.3 meters, and the wingspan is only 12.88 meters. (These dimensions are based on online guesses. All subsequent J-20 data are fabricated by the hero of East China.)

So, in terms of size, the J-20 is smaller than the J-15!

Of course, it is also said that the wings of the J-5 can be folded. After folding, the wingspan is only 8.4 meters. The wings of our J-20 cannot be folded.

It is true that the wings of the J-20 do not need to be folded at all. When boarding the aircraft carrier, as long as they are adjacent to each other end-to-end and alternately arranged forward and reverse, like the French Rafale fighter jets, the delta wing characteristics of the J-20 can be used to achieve this. Lower deck landing area purpose.

Why can't the wings of a stealth aircraft be folded? These are all layman's terms. Look at the American F-35. The wings of the carrier-based aircraft still fold after being put on the ship. The domestically produced J-32 still folds after being put on the ship. Wing, that's no big deal.

 So, size is not an issue. What’s next? Salt and moisture-proof treatment for stealth coating?

 Mingzhou Group’s stealth aircraft has been put on board the ship, and these have been resolved.

What else is not suitable for the J-20 to be put on a ship? Weight issue?

The empty weight of the J-15 is about 20 tons. The J-20 is one size smaller than the J-15. Is it possible that the empty weight of the J-20 can be greater than that of the J-15? After all, the J-20 uses a lot of composite materials, so the empty weight should be lower.

Anyway, there is a catapult. Since it can eject the heavy J-15, of course it can also eject the heavy J-20.

 Are there any restrictions on the arresting cable during landing?

We use a tall electromagnetic arresting cable. The blocking strength is dynamically adjustable. The carrier-based aircraft can withstand a large landing weight. At most, the J-20 can burn more fuel in the air. Landing with bombs is definitely not possible. Problem.

These technical problems can be solved. The only problem is that because the J-20 has not been put on the ship, everyone has great doubts. However, on TV, there is a J-20 in the leaked model. This is a lie. Whether it's still being studied in real terms, I don't know.

“We have also improved the landing gear at the back.” Zhao Dangsheng continued. At this time, at this production station, the landing gear at the back of the two fighters has also been installed.

During landing, the rear landing gear is meant to withstand impacts, but carrier-based aircraft bear greater landing impacts, so the rear landing gear requires higher strength.

"From the outside, the thickness of the rear landing gear is the same. However, we used the latest high-strength steel developed by the Mingzhou Group on this 04 sortie fighter. The yield strength is as high as 2100 MPa and it is corrosion-resistant. The ability is very strong, and this kind of steel has reached the first place in the world."

"We are from the Mingzhou Steel Plant?" Qin Tao was also curious: "Why don't I know?" "Mr. Qin, you have so many things to do, how could you pay attention to such a small progress?" Zhao Dangsheng also joked: "But for For us, this is a huge progress. The J-31A and J-32 we are currently producing have begun to be equipped with this kind of steel landing gear. The weight has been reduced by a full 20 kilograms, but the strength remains unchanged. "

Twenty kilograms is the weight of a bag of rice, but for carrier-based aircraft, not to mention a bag of rice, even the weight of a grain of rice must be considered. After all, when a fighter aircraft performs 9G overload, these weights It will become nine times the original size!

“Well, not bad.” Qin Tao nodded: “I am very proud to contribute to our aviation industry.”

“In order to meet the requirements for taking off and landing on an aircraft carrier, the ventral fins on this aircraft have also been reduced in length in the vertical direction and expanded in the horizontal direction to avoid rubbing the ground at an excessive angle of attack.” Zhao continued to introduce.

Fighters always raise their nose when landing, so that the main landing gear at the back can touch the ground first. If the elevation angle is too large and the fuselage is too long, the tail of the aircraft may rub the ground. The J-20 aircraft The body is very long, so this problem must be prevented.

"Well, yes, you are professionals." Wu Shengli looked at the carrier-based aircraft being assembled and was very satisfied: "After it is assembled, you are welcome to come to our base in Wasteland Village at any time!"

 Carrier-based aircraft must go to the aircraft carrier. Before boarding the aircraft carrier, they need to go to the wasteland village for testing.

“We have to go to the flight test institute first and complete various scheduled test flight projects before moving to the wasteland village. Of course, this process will still require a large amount of capital investment. I hope the navy’s funding will not be cut off.”

"Of course it won't stop." Wu Shengli said: "Even if we misappropriate aircraft carrier construction funds first, we must satisfy your research and development."

Qin Tao looked unhappy at the side, Dad, other people’s projects are coming soon, so only our Mingzhou Group can default on the money, right? Anyway, even if we are in arrears, we don't dare to delay the construction period, we still have to pay in advance.

Zhao Dangsheng glanced at Qin Tao and thought of something: "Leader Wu, during the research and development stage, we can build a prototype of the carrier-based aircraft, but in the future, when it enters the production stage, I am afraid we will not have the production capacity to produce it for the navy."

“Why, our navy also contributed money during the research and development stage!”

Wu Shengli was very dissatisfied.

“Leader Wu, you only paid for the modification, and the early research and development is the bulk. We must give priority to the Air Force.” Zhao Dangsheng said.

It's like after the Su-27, the research and development of the Su-33 became very easy. Even the initial prototype was improved with a T-10. Such research and development funds were very small, less than the research and development of the prototype. A fraction of that.

The Navy contributed money, but it was a small sum, while the Air Force contributed a lot of blood. Therefore, priority must be given to the use of the Air Force.

This issue was discussed last time, but Zhao Dangsheng continued to bring it up.

Thereupon, Wu Shengli looked at Qin Tao for help.

“Dad, what are your plans?”

“Taozi, our navy must have this kind of heavy-duty carrier-based aircraft, right?”

 “Dad, if you have anything to say, just say it.”

“If our navy orders this kind of heavy-duty helicopter, will there be fewer orders for your J-32s?”

 “Our orders are already scheduled for ten years.”

"I'm talking about orders from the navy, orders from the navy of our motherland!" Wu Shengli's tone became more serious: "So, the work stations originally used to produce J-32 carrier-based aircraft for us will be used to produce this fourth-generation heavy-duty aircraft. How is the machine?"

Qin Tao refused last time, but Wu Shengli obviously didn't give up, and now he brought it up again.

"Dad, when we produce carrier-based aircraft for the Navy, we originally grabbed other people's orders. When the aircraft carrier was delivered to the big business, we should have given them all the carrier-based aircraft. Now we have only given ten of them because they were ordered by the Navy." It’s occupied. If the Navy doesn’t order it, then we can also produce other orders. We will still produce normally, we..."

Seeing Wu Shengli's displeased expression, Qin Tao quickly changed his words: "Besides, the technology was developed by 611, and it has nothing to do with us. We have to produce it, so what's going on? There are a lot of business matters involved."

“We have no objection.” At this moment, a voice came from outside.

Mr. Song and the others have finished the finishing work for the first flight and are here!

"Although the J-20 was developed by us in name, your Mingzhou Group also helped a lot." Mr. Song said: "You made our front fuselage, and the frontal stealth effect is up to standard. You played a big role." role, so you also have the right to share this technology.”

After finishing speaking, Mr. Song thought of something and continued: "If you don't join in, we will not have enough production capacity. The Air Force cannot wait and may ask other groups to join in."

 Qin Tao's eyelids twitched.

 What are the other groups?

 There are only two national teams that manufacture fighter jets in China!

If Qin Tao doesn't join in, the meat will be robbed by others, and he will still consider himself the boss in the future.

Qin Tao thought for a while: "Mr. Song, I have a suggestion."

 “What suggestions?”

“After you develop the fourth-generation heavy-duty aircraft, you should go all out to produce the fourth-generation aircraft. After all, this is what our navy and air force are most in need of.”

“Well, but our J-10 is also very good and cost-effective. We have to replace a large number of old fighters in the past, and we cannot replace them all with advanced heavy-duty aircraft.”

 The stealth machine is very useful. It can be used to knock on the door. But what happens after knocking on the door? A large number of fighter planes without stealth capabilities will definitely be needed to bomb!

It is impossible to replace all domestic aircraft with stealth aircraft, especially since there are a large number of J-6 and J-7 fighters. The last J-6 was retired in 2010. In these years, aircraft such as J-10 will definitely be needed to replace them.

 The production of J-10 is a must.

“You can leave the production of the J-10 to your brother units, and you can go all out to produce the J-20 yourself.”

Mr. Song’s eyes lit up.

The J-10 is of great significance to them. It was precisely because of the development of this fighter that they took the road of self-development. Without the success of the J-10, there would be no J-20.

However, when the J-20 came out, the J-10 fell behind. In other words, because of the Mingzhou Group’s fourth-generation stealth aircraft, the J-10’s positioning became very awkward after it came out.

Now that they have produced the J-20, the production of the J-10 can be handed over to others, freeing up the factory to produce all the J-20!

“If it’s not enough, you can add a new production line. If you don’t have enough funds, Mingzhou Financial can give you a loan.” Qin Tao said.

Mr. Song nodded: "Mr. Qin, your methods are very good, but why don't you participate in the production of the J-20? We have always been grateful to the Mingzhou Group for its support, but there is nothing in return. We really want to I leave the production to you to produce this kind of heavy-duty machine together. With your rich experience, the quality produced will definitely be very good."

Qin Tao smiled: "We still want to be shameless. We develop and produce our own products. Only in this way can we have the confidence to use other people's products to produce them without making progress. We are not that thick-skinned yet."

This sentence is of course a satire on some people, who regard themselves as big brothers, but have no other abilities except crying for milk.
