Chapter 285 F-35 version of J-31
"Taozi, this trick of yours is really effective. If the Air Force is determined to develop it on its own, then it can get a smaller early warning system and install it on the Yak-44, and our Navy can test it. ." Wu Shengli said.
On the way back to the car, Wu Shengli was in a good mood, while Qin Tao looked at the falling snow outside the window and felt a little complicated.
There is a long way to go, and the development of various weapons needs to be on the fast track. However, the country's economy is now limited, and it is not easy to develop all projects.
Making money is the first priority, but Qin Tao seems to be thinking too much. These things cannot be solved by him alone.
“Dad, I have another idea.”
"explain."
"Lao Maozi's people will come soon. I will take them to the 611 Institute to start the project and conduct preliminary research first. However, we also need to have a name for this project. What’s a good name?”
"J-11?" Wu Shengli reacted quickly, and after arranging them by model, it was the turn of the 11th.
Qin Tao shook his head: "Let's be bigger."
“We already have twelve and thirteen, how about we annihilate fourteen?”
“No, this name is unlucky.”
“Then what do you say?”
“How about J-31?” Qin Tao said.
Generally speaking, any aircraft project must be approved by relevant departments, so that it can be considered legitimate. Now, it is too casual to give it a name casually.
However, Wu Shengli had nothing to say: "Okay, as long as you like it, it won't conflict with our other projects, that's it."
Qin Tao smiled. When he said this name, he still felt a special kind of pleasure.
Three days later, 611.
Lao Song and Lao Tu all came, Wu Shengli and Qin Tao came together, and even Lao Lin came over to join in the fun after hearing about it.
"Everyone, welcome to the Land of Abundance. From now on, this will be your home. We welcome you to join us and have specially set aside a building for you." Mr. Song pointed to a gray three-story building. Inside the building , and it was repainted.
Pleshakov's mood is complicated. He has traveled thousands of miles to come here, hoping to start a new life. It is already winter, but there is not a trace of snowflakes here, but there is some mist around. , giving people a gray feeling, and his heart also became a little depressed with this mist.
"Everyone has just come here and is quite tired. It's better to go and have a rest first. Then we will hold a reception banquet. There is enough wine here for you to drink as much as you want. When everyone comes to rest, we will officially start working." Qin Tao said road.
It should be very easy to attract an old man with fine wine.
But this time, Qin Tao's deception failed. Pleshakov shook his head: "No, we want to get into work immediately. We need to have a meeting first."
This guy, is he worried that he will deceive him?
This thought came to Qin Tao's mind, thanks to the fact that he is a man of his word.
“Okay, let’s go to the conference room first.”
Mr. Lin walked quickly and followed it. Although it was a naval project, with his level, it was no problem to go and observe.
Lao Song, Lao Tu and others also followed in. When everyone was seated, Qin Tao began to preside over the meeting.
“First of all, let me introduce it to you.” Qin Tao said: “Mr. Mao Duanzhang is a senior engineer who developed the Yak-141. He will also be fully responsible for our new J-31 project as the chief engineer of this project.”
(The previous Mao update, the comments are very interesting, so let’s call this pseudonym Mao Duanzhang. There are also Mao Duanshang in the back. Anyway, this name sounds like Mao Duanchang.)
There was a round of applause below.
"Mr. Mao, in addition to the group of people you brought, we have also prepared a capable R&D team for you. They have also studied vertical take-off and landing fighters for a long time and accumulated a large number of He has rich experience." Qin Tao said: "Please introduce Mr. Song."
Mr. Song nodded: "Comrade Zhao Dangsheng is in charge of our representative for this project. At present, there are fifty-three representatives of our team in this team. Including the thirteen people brought by Mr. Mao, the total number is sixty." Six people, although the team size is not large, I believe that you will be able to create miracles!"
There are more than fifty people working in Institute 611, which is quite a lot. These people are all squeezed out from the developers of Project No. 10, which is quite a lot. The initial research team can be considered to be established.
Pleshakov sat there and said nothing. To him, these people were definitely not many, but since he had just come here, there were not many of them. He could not force them.
"Now, let me introduce our project." Qin Tao said: "The J-31 is a key project of the Navy, and the Navy has very high requirements for it. First of all, there are three models of it. "
Three models?
This project aroused Pleshakov's interest.
“First of all, it is the vertical take-off and landing version.” Qin Tao said: “This version is also the focus of our research and development. Since our energy is limited, the first thing we must overcome is this version of technology. This is the biggest prerequisite.”
"However, on the basis of this version, we can further develop it. We only need to remove the lift fan at the front and the vector nozzle at the tail, strengthen the landing gear at the front, and it can become a conventional catapult take-off and landing for the Navy, blocking the landing. Carrier-based aircraft.”
“Based on the naval carrier-based aircraft, reducing the weight and only meeting the needs of land use, it can be used as the most common fighter aircraft.”
Three models in one machine! Of course, Qin Tao plagiarized the design concept of the F-35. However, unlike the F-35, which first studied the simplest land-based fighter, they developed the most complex vertical take-off and landing fighter. Simplification on this basis is more in line with them. demand, in this way, other models can be transformed at any time in the future.
However, his theory moved Pleshakov.
The Yakovlev Design Bureau was once so powerful. During World War II, the Yak fighter jet was the best! However, after entering the Jet Age, they were marginalized.
In terms of aircraft design skills, they are no worse than Mikoyan and Sukhoi! It's just that they don't have a stage to show off.
Now, in the east, they finally have this opportunity, and Pleshakov is already excited.
Who likes useless vertical take-off and landing fighter jets? They also want to build advanced fighter jets!
Now, the opportunity has finally come. First develop a vertical take-off and landing fighter jet, and then develop a regular version. If the vertical take-off and landing fighter has the ability to compete with other third-generation aircraft, then their regular version will definitely be able to overpower others. ah.
Excitement, excitement, happiness!
Mr. Lin also felt emotional there. If others didn't know, how could he still be unclear? With the navy's small amount of funds, it is difficult to build a Flying Leopard. If you have one aircraft and three types, just brag about it!
Of course, he was just attending the meeting. He couldn't tear down Qin Tao. Otherwise, how could he have the nerve to ask Qin Tao for help in the future?
Wu Shengli sat there, full of expectations.
One machine and three models, this is a good idea! The Navy will also have its own advanced carrier-based fighter jets in the future, so it does not have to pick up leftovers from the Air Force. Moreover, this will also facilitate versatility.
At this time, Qin Tao was just laying the groundwork. He didn't know how far it could develop in the future, but he knew that the J-15 purchased by the Navy was more expensive than the J-20 of the Air Force. A third-generation Non-stealth fighters are more expensive than fourth-generation stealth aircraft, so the Navy can only grit its teeth and accept them because there is no other choice.
"Now, let's talk about the vertical take-off and landing fighter aircraft in detail." Qin Tao introduced: "I drew a design drawing. Of course, due to my limited skills, the drawing must be full of mistakes. It only serves the purpose of The role of throwing bricks and linings up."
The projector was turned on, and the image on the projection screen gradually became clearer. When they saw the design, everyone opened their eyes wide.
"The era of stealth aircraft has arrived, so our newly developed vertical take-off and landing fighter must have stealth capabilities." Qin Tao introduced: "Now, these are my personal thoughts. Let's start from the front Let’s start with the rhombus-shaped nose. This layout allows frontal radar waves to be reflected in other directions, reducing frontal echoes. In this way, parallelograms can be arranged on both sides of the nose. of the air intake."
Although the F-22 project was carried out very early, it was not until 1997 that the prototype began to fly. So now, professionals’ understanding of stealth aircraft is just a flying brick like the F-117, which all depends on the engine. Awesome.
Now, seeing this appearance design, they were extremely excited, especially Mr. Song, whose eyes were full of energy.
"Behind the nose is the lift fan, and then the main engine. Between the two, we can insert the built-in bomb bay, which extends backward from the bottom of the inlet at a certain angle, so that it can avoid Turn on the drive shaft and lift engine.”
If you want an aircraft to achieve stealth capabilities, you must have a built-in bomb bay. However, the built-in bomb bay will occupy the precious space of the aircraft, resulting in a shortened flight range and a small number of weapons to carry. It depends on the choice.
At this time, when he heard this, Pleshakov could no longer bear it: "If it is designed like this, then our original design of the Yak-141 will almost have to be overthrown and restarted. We need to start from the beginning. The hole begins.”
Do you know that Project No. 10 has remained on paper since its establishment in the 1980s until now? It's not because of money. Without money, we can only talk on paper.
Now, Qin Tao has proposed so many high-end technologies just to delay time. In a few years, the country will have money.
No, it’s for technology!
"With all due respect, the original design of the Yak-141 is already outdated. If this aircraft wants to be able to adapt to the sky of the future, then it must be improved!" Qin Tao looked at Pleshakov seriously: " Do you want to build an aircraft that will be outdated as soon as it comes out, or do you want to use advanced concepts to make your aircraft not obsolete in the next thirty or fifty years?"
How to choose? Needless to say?
Pleshakov calmed down: "Yes, although it can no longer be called the Yak series aircraft, we all came here to realize the glory of the Yak Design Bureau. Now, this aircraft has entrusted all our efforts. I hope it must have more powerful performance. The sky of the future belongs to the stealth era. We have to develop this aircraft even if we start from scratch!"
"Okay, let me continue." Qin Tao continued to introduce: "In terms of wing selection, we use butterfly wings, which means that the back of the wings must be swept forward, which can further reduce radar reflection waves. , is the best choice for a stealth aircraft. With the full-motion horizontal tail immediately behind it, there is no need for the extended shelf on the tail of the Yak-141. The two vertical tails are tilted outward, which can further reduce the radar reflection area."
“However, this will also greatly increase the difficulty of flight control.” Mr. Song spoke.
The vertical tail is very simple to handle. Just turn the rudder in which direction you want to turn. However, when the vertical tail is tilted, the aerodynamic effect is no longer linear, which greatly increases the difficulty of control.
The biggest difficulty in the research and development of their Project 10 is the exploration of flight control rate and the writing of flight control programs. Now, this kind of aircraft is even more extreme.
"That's right, but we have no choice. We must overcome all these problems." Qin Tao said: "Even if the pre-research time is longer, we still have to calm down and do research. As long as we work hard, we can do it." Grind it into a needle."
Pleshakov nodded: "Yes, the products of Mikoyan Design Bureau use this idea. The two inclined double vertical tails can play a stealth role. Since we need to make major changes, then we will do it You have to be more thorough.”
Did you see it? This is the ideal, this is the power of faith!
Qin Tao sighed in his heart.
“Next, there are several subsystems. I will then introduce the power system part, which is also our core.” Qin Tao switched to the next slide.
"Alexander and I have already introduced it, but many people here may not have heard it, so here, I will introduce it again. It is inappropriate to use a turbojet engine as a lift engine. Starting from the Yak-38, The problem of the lift engine's nozzle flame burning the flight deck has never been truly solved." Qin Tao introduced: "So, we must change it to using the rear engine to drive the lift fan."
The design drawing appeared clearly in front of everyone's eyes. They looked at it carefully and understood the mystery.
"This can greatly reduce the fuel consumption of vertical takeoff and landing, which is equivalent to the relationship between a turbofan and a turbojet." Qin Tao introduced: "Of course, there are many difficulties. For example, the transmission shaft must be able to The output is 20,000 horsepower, the rotation speed must be over 8,000 rpm, and there must be a clutch to undertake the coupling task. In particular, its weight cannot be too great.”
The people present were all professionals, and they all took a breath of air. Damn it, can this thing be done?
“This technology is very difficult, so the Navy can hand over this subsystem to our propeller factory in Huating.”
The propeller factory in Huating?
This factory is producing high-precision marine propellers, and it also has advanced equipment. As long as the materials are qualified, it might be possible to make them.
“Yes, I can leave it to you.” Wu Shengli agreed.
“Next, let’s talk about flight control. For such an aircraft with complex operations, a four-degree digital fly-by-wire system must be used to ensure flight safety. In this aspect…”
“You can leave it to me, I’m the one responsible for flight control.” Zhao Dangsheng said.
Speaking of the flight control system of Project 10, the person most likely to think of is Mr. Yang. After all, he is the chief designer of the J-20, and his brilliance began with the writing of the J-10 flight control system.
However, this must also be the credit of the entire team. Zhao Dangsheng is also engaged in flight control. Before being assigned the task, Zhao Dangsheng was working with Yang on the flight control of the J-10.
Canard layout and statically unstable J-10 flight control can be achieved. Of course, there is nothing to say about the flight control of this vertical take-off and landing fighter.
In this way, several important parts of the fighter jet have been arranged.
The team led by Pleshakov mainly worked on the airframe, Zhao Dangsheng led people on the flight control, and Qin Tao helped with the lift engine. Is the R-79 produced according to the imported technology, or is it continued to improve the core? That is not Qin Thao was worried.
The four major aspects of a fighter jet, as well as avionics, don’t worry about this for now. Just replace it with counterweights first. Later, you can just transplant the J-10’s fire control. Anyway, they are all products of a research institute.
Now, with such an arrangement, it looks like the real thing.
“If we want to redesign the aerodynamic shape, we need an advanced wind tunnel and a specialized electromagnetic laboratory.” Pleshakov raised the last question.
"That's no problem." Qin Tao nodded immediately: "We have a 1.2-meter transonic wind tunnel in China, which can fully meet the needs. For the electromagnetic laboratory, we can also find a special room in this small building. , we can purchase any equipment we need. By the way, how much money does the Navy expect to allocate first?"
Qin Tao looked at Wu Shengli.
In 1984, a 1.2-meter transsonic wind tunnel was built in China. Without this thing, the J-10 would not have been built.
“First of all, a start-up capital of 10 million yuan.” Wu Shengli said.
Speaking domestically, of course it is not US dollars, but RMB. What can these ten million be used for? The navy is really stingy!
Qin Tao sighed with emotion and said to Pleshakov: "The Navy first provided 10 million, which is just the start-up capital. Now it is almost 1993. As long as the new year comes, the Navy will have more resources." Come with more funds."
Pleshakov nodded.
The meeting was over, and all the old men present were relieved. Qin Tao did not fool them. They came here and could continue to do what they wanted to do!
With their work arranged, they felt relaxed. When they arrived at the cafeteria and saw the dinner specially prepared for them to catch up with the wind and wash away the dust, these people were even more happy. They carried the wine bottles and regained their normal image of old men.
Qin Tao also carried a bottle of wine and toasted with the old men.
"Qin, I have a question." Pleshakov looked at Qin Tao seriously: "Are those designs of yours really designed by yourself? Although we haven't tested it yet, we can predict it based on theory alone. , this design will be very good.”
Of course it was not designed by me. I am a ship builder, not an airplane builder. These shapes and design concepts are just copied mechanically. This is the advantage of a reborn person.
Qin Tao thought secretly in his heart, but said: "Old Mao, you shouldn't ask this question. You also know that there are many secrets in me, and this is also a secret."
Qin Tao was so fooled.
That’s right, it’s a secret!
It would be several years later that Pleshakov would suddenly discover one day that Qin was so capable that he could actually get out Lockheed's secrets. How did he do it?
Of course the space-time machine helped. Lockheed has not designed it yet, so how could Qin Tao get these things?
Pleshakov smiled: Drink, then drink!
Lao Maozi had satisfied his craving that day and drank bottle after bottle of wine. It didn’t take long for them all to fall down.
Although strict discipline will be required in the future and they cannot be allowed to drink like this, but now, these people are new here and they have to drink to their heart's content.
After all the old men were carried away, the atmosphere in the cafeteria became very strange.
“Mr. Qin, where did your design come from?” Mr. Song asked.
“Yes, you want to build three models, and they also have stealth capabilities. If this aircraft comes out, will our project be finished?”
Everyone feels a deep crisis.
"Although I don't know what our project is, after using the Su-27 engine, it should be possible to build it soon and enter the test flight stage of the prototype." Qin Tao said: "Within ten years, Our project here may be successful, but what about Lao Mao's project? It will take several years to blow up the wind tunnel and make the appearance. The engine technology and flight control technology are all mature. It is estimated that it will take ten years. Ten years have passed. It will be great if the prototype can fly into the sky. It is still early to enter service! What are you anxious about and what are you afraid of? "
"This project is for the Navy, not the Air Force. Now, Mr. Lin is here. Ask him, what does the Air Force choose?"
“Taozi, you’re such a big cake, I’m even a little greedy when you draw it.” Mr. Lin said: “If that land-based fighter without any reinforcement can be developed, our Air Force would be really interested.”
Mr. Lin actually wants to add insult to injury?
Qin Tao smiled: "Okay, you can't eat ready-made. Since you want it, then start allocating funds for this project from now on. We don't want more. The Air Force will allocate as much as the Navy allocates. If not Give me some money, haha, go cool down next to me!"
