"With the development of the times and changes in technology, it is a trend that the cost of heavy fighter jets has skyrocketed." Daniel said: "After all, modern fourth-generation aircraft use a lot of advanced technologies, not to mention other things, just its avionics The equipment is a long way ahead of the competition.”

"The fourth-generation stealth aircraft produced by Oriental still uses a flat-panel slot radar antenna, while our F22 is already a phased array radar. This kind of radar can search for any target without rotating and has powerful multi-target interception capabilities. Moreover, concentrating the radar beams together will make it easier to detect stealth aircraft." Daniel said: "This kind of avionics equipment alone costs a lot of money, but compared to its performance, it is still worth the money. "

"And its engine is the only advanced engine in the world that can reach a thrust-to-weight ratio of 10. This level of engine gives our fighter jets the ability to fly at supersonic speeds without using afterburner, and the price will naturally be high. A big chunk."

 There is a reason why it is expensive. Our fighter jets are technologically advanced, so of course they are more expensive.

 Speak out the theory first, then sell it.

"However, since the development of the F22 fighter jet has been completed, the development costs are all funded by the Air Force. Therefore, the Navy does not need to spend too much R&D funds, and we can transform this aircraft into a naval model." Daniel said : "You have invested more than 40 billion US dollars in JSF, which exceeds the research and development funds of F22, and there is no hope yet. We only need 10 billion US dollars to complete the transformation of the naval type, and in the follow-up The purchase price will be controlled within 200 million U.S. dollars, which is absolutely value for money for the Navy. The R&D funds you spend on JSF can already purchase hundreds of F22 fighters."

“Just for modification, it will cost 10 billion US dollars? Do you want to modify it into a variable-sweep wing fighter?”

"Of course not. The era of variable swept wings has long passed. The butterfly wings of our existing F22 fighter jets can meet the take-off and landing needs of carrier-based aircraft. The Navy does not need to insist on variable swept wings. This is The US$100 million improvement project mainly includes the salt and moisture-proof treatment of the airframe, landing gear, landing hook, skin and engine, etc.”

Everyone frowned. Just these projects cost 10 billion. Isn’t it too dark?

"If the Navy does not support our project, it can only continue to develop the F32. This project has no hope. Many of its basic designs are wrong. During the development process, it was improved from a large delta wing to normal aerodynamics. Layout is an example. Boeing does not have the ability to develop modern stealth aircraft at all. Only Lockheed has successful experience." Daniel said: "Think about it, you can tolerate that the performance of the Navy's fighter jets is not as good as that of Eastern products. Fighter plane?"

Swift nodded: "Yes, we need a modernized fourth-generation heavy-duty stealth aircraft. However, this project still needs to be approved by Congress. Even if it is passed, we can only allocate hundreds of millions to start feasibility studies."

“We are waiting.” Daniel said: “When our F22 naval model is developed, the navy will be amazed by its performance. Our X-35 can also be further matured through the development of this fighter.”

 When things came naturally, Daniel brought up the X-35 again, they haven’t lost yet!

“Is your X-35 still under development?” a naval leader asked.

"Yes, it is still under development. We believe that the layout of our X-35 is the most suitable." Daniel said: "We use lift fan technology, which not only has the ability to take off and land vertically, but also makes the conventional model more Conventional, after all, vertical take-off and landing models are only a minority, while conventional take-off and landing are the majority.”

The joint military service is a trap! The Navy's carrier-based version and the Air Force's land-based version are both restricted by the Marine Corps' vertical take-off and landing model!

The Flying Toad was made like that just to compete with vertical take-off and landing fighter jets. As a result, the shape was weird, space wasted, and it also caused serious problems of overheating of the fuselage!

We were really lucky last time. If the fire on the plane was not extinguished in time and burned the ammunition compartment in the middle of the fuselage, there might be an explosion.

 So, the structure of the F-32 has serious flaws and it is impossible to succeed!

The configuration of the X-35 is similar to that of the East. Since the East has matured it, it means that this route is feasible. Is it necessary to abandon this technical route for the sake of face?

“You will develop the naval version of the F22 first, and we will discuss the JSF plan later,” Swift said.

They can't make the decision. If they could, they would have done their own thing long ago. It's not because the White House wants to reduce R&D expenses and forcefully combine them. Facts have proved that forceful melons are not sweet!

Facing the situation, the Americans will unify their thinking sooner or later. Needless to say, the JSF plan will tend to copy the Mingzhou Group's fighters. In the future, they may also copy the J-20.

 Far East, Wasteland Village.

"The U.S. Navy has decided to develop a naval model based on the F22." After Wu Shengli and Qin Tao watched the first flight of the J-20 carrier-based aircraft, they did not leave immediately and stayed here for a few days to experience the navy. Aviation atmosphere.

 Then I got the news.

Qin Tao nodded: "In the context of the proliferation of our fourth-generation stealth aircraft, the U.S. Navy will of course upgrade their weapons and equipment. They plan to use the carrier-based version of the F22. This is not surprising."

Of course Qin Tao would not expect that the U.S. Navy would continue to use Fertilizer or Flying Toad. They have been so seriously stimulated that they will definitely look for more advanced models.

 “This will make the situation we face in the future even more severe.” Wu Shengli said.

 “What’s so serious, Dad, how do you think the Red Empire collapsed?”

There are of course many reasons for this, but what Qin Tao is going to talk about now is definitely just one of them.

“Drawed down by Star Wars?” Wu Shengli quickly responded: “You mean, even if the U.S. Navy selects the F22 as a carrier-based aircraft, it cannot afford to equip it?”

"It's best for them to equip themselves by force. In this case, military expenditures will continue to exceed expenditures. It depends on how long they can sustain it." Qin Tao said.

The Yankees have a world-class navy composed of ten aircraft carriers. Each aircraft carrier can carry more than 80 carrier-based aircraft. Even if each ship only carries one carrier-based aircraft group, which is twenty, it still needs to order two Hundreds of frames.

Even the Air Force has received less than 200 F22s. How can the Navy purchase so many? You know, the Air Force's funding is aircraft, and the Navy's funding is not only aircraft, but also warships, and warships even cost more!

 This is a big flag.

 We are not afraid because our planes are very cheap.

　Our six Aegis battleships were built together, and we finally became wealthy. Why? It’s not just because it’s cheap. The six ships we built are equivalent to the British building one Type 45. The low cost makes them envious.

 They can only be envious. Do they have the nerve to come to Mingzhou Group to order?

In fact, for the U.S. Marine Corps, ordering the J-31A from the East is the most cost-effective. Anyway, only one of their branches needs to be equipped with vertical take-off and landing fighter jets, and the others do not.

While talking, the two walked into the flight simulation room. Inside, a brand-new simulator was rolling on the stand. The pilot inside was obviously doing various maneuvers. On the control panel outside, sat a beautiful girl.

“Xiang Jing, is that Xiang De inside?” Qin Tao asked.

“Yes, it’s him. He said he went in to practice taking off and landing, but now, he is practicing air combat, and the simulation object is F22.”

There is also a large screen on the control panel outside. What is displayed on the big screen is two fighters, one black and one silver. The two fighters are constantly flipping in the air and performing various complex maneuvers. . “Our computer performance is really good.” Qin Tao said with emotion.

This kind of complex air combat simulation requires powerful computing power of computers. It is definitely not comparable to computer games. Every detail in it must be completely restored.

“Of course, our simulator uses the latest Loongson-6 computer. Although there is only one processor in it, the performance is equivalent to ten Loongson-4 processors.”

In the past few years, technology in various domestic industries has continued to advance, and the same is true for Loongson computers. The most advanced Loongson 6 processor has used mature 65-nanometer technology. Although the data is not much different from 90-nanometer, the actual The standard cell gate density it supports is twice that of the 90-nanometer process, it accommodates more transistors, the chip generates less heat, and its performance is more advanced.

Of course, this is still the most mature process. In SMIC's laboratories, 40 nanometer and even 28 nanometer processes have begun to be studied. In this field, China already has a complete industrial chain. If any one does not If anyone dares to cause trouble, it's just a small photoresist that can tightly restrict foreigners.

 Qin Tao is also sighing when he thinks about the progress in domestic chip technology. We are finally far ahead in many industries!

“You have returned from a mission this time and have a certain period of vacation. Where do you plan to travel?” Qin Tao asked Xiang Jing.

“We are not traveling anymore.” Xiang Jing said: “He has always thought about flying the J-20 quickly and waiting to get on the aircraft carrier.”

At this moment, a ball of flame appeared on the screen, and the F22 in the fight was finally knocked into the air and exploded.

The plane returns and lands, simulating the deck of an aircraft carrier. After it stops, the canopy opens and Delano comes out.

“It’s great!” Delano said: “This simulator is more realistic and more powerful. If it had a helmet sight, the enemy plane would have died ten thousand times!”

 After saying that, Delano looked at Qin Tao: "Mr. Qin, when will my helmet arrive?"

"It will take at least a week, why are you anxious?" Qin Tao said: "This computer game is very enjoyable, right? It is built with our most advanced Loongson 6 processor."

Originally, Qin Tao was just selling melons, but Delano shook his head: "No, no, Mr. Qin, it seems that you don't understand computer games. Such advanced computer games mainly depend on the performance of the GPU. Instead of the CPU, our J-20 fighter uses a large number of video processing devices, and the performance of these devices also depends on the GPU."

Qin Tao was stunned. That’s right. Up to now, the level of graphics processing power has little to do with the central processing unit. It mainly depends on the graphics processor!

ˆ Relying on advanced chip production technology, we have already begun to lead in this field.

In the early days, computers did not need advanced graphics cards. After all, the computer just displayed Chinese characters. It only needed to plug in a few integrated circuits on the computer board. With the emergence of graphical interfaces, graphics cards became more and more important. , when the display graphics transition from two-dimensional to three-dimensional, an advanced graphics processor is needed.

In this way, specialized graphics cards developed and became more and more important. In the later period, the performance of CPUs began to be excessive. Users could use a CPU for many years. However, the market for GPUs was still vibrant. Therefore, companies specializing in the production of CPUs Manufacturers can only watch helplessly as the manufacturers of graphics cards make a lot of money, and the price of GPUs far exceeds that of CPUs.

 What is the difference between the two? Why can upgrading the GPU improve computer performance, but upgrading the CPU has little meaning?

 This is of course the difference in structure and mission between the two.

The CPU is a general-purpose processor, responsible for all types of calculations, and is of a large and complex type. It has only a single core or a few cores, and the most is a dozen. The performance of each core is very strong and can accept a large number of Instruction sets and complex computing tasks. Such a processor has high performance in single-threaded and few-threaded situations.

The GPU does nothing else but accelerates graphics rendering. It mainly performs parallel calculations. Therefore, it has hundreds or even thousands of cores inside. The performance of a single core is not strong, but there are many, and they can be executed simultaneously. There are hundreds of thousands of threads, each thread is performing the same task, thus achieving efficient parallel computing. If you look at the data of the graphics card, one of the important indicators is the number of stream processors. This stream processor is The core of it.

In 2006, the FermiGTX480 released by Nvidia had 480 stream processors, and by the 2020 3080 graphics card, the number of stream processors has reached 8704. With so many cores, it is like ants eating elephants, taking a large number of The computing tasks are divided into small computing tasks, and then high-speed parallel computing is not only rendering graphics, but also plays an important role in big data, dynamic simulation, artificial intelligence, autonomous driving and other fields.

  Of course, graphics cards are also used in the field of military aircraft. Take a look at the Yankees' F35. The head-up display is removed. The tall helmet-mounted display can display video, relying on the NVDIA display chip.

Now, Dongfang has reached the forefront of the world in this field. At this time, listening to Delano talking about this, Qin Tao also instantly thought of the arrogant old man in later generations, shouting about cracking down on scalpers, but in fact He secretly gave a large amount of inventory to scalpers, while he hid behind and counted the money.

 What about our Loongson Corporation and SMIC? Is the profitability strong? With such advanced technology, it must be sold at a high price.

Just when Qin Tao was about to talk to Mr. Ni and others, a person walked in from outside.

“Yes, Mr. Qin, we didn’t expect that developing high-performance GPUs would be so important.”

 Qin Tao turned his head and saw a familiar figure: "Mr. Ni, why are you here?"

"This set of equipment is equipped with our latest display chip, so we are tracking customers to see how it is used." Mr. Ni said: "I didn't expect to see Mr. Qin here. Mr. Qin, when you It was suggested that we should develop display chips, and it was indeed true. Now, our investment in display chips has exceeded that of central processing units."

 At the beginning, Loongson processors finally reached the world's number one level. They felt lonely and wanted to lose, and they didn't know how to develop next. At that time, Qin Tao proposed the development direction: graphics cards.

At that time, Mr. Ni and others were still a little disapproving, but now, they have discovered how huge the potential of graphics cards is. It can not only be used in civilian computers, but also has great military uses!

If a fighter simulator wants to realistically simulate various air combat situations, it must have powerful display computing capabilities. If the performance of the fighter itself is to be advanced enough, it must also have a powerful display chip.

“Our research on display chips will not affect the development of central processing units, right?” Qin Tao worried.

"Of course not. We have sufficient financial resources to support our research and development. At the same time, our teams are also separated. The team that researches graphics cards is a new team that we recruited technical personnel from 3dfx Company. Mr. Qin, Your original judgment was absolutely correct!"

 When Loongson did not enter the graphics card business, the leader in this market was 3dfx. Who would have thought that the largest graphics card manufacturer at the height of its power would support itself to death by acquiring the board supplier SRB.

 Only Mr. Qin expected that Loongson Company made plans in advance. When 3dfx was about to go bankrupt, it poached almost the entire graphics card R&D core team and formed Loongson Company's own R&D team.

Technical personnel are now available, as are advanced chip production technologies. Loongson has become the leader in graphics card manufacturing.

 Thinking of this experience, Mr. Ni was very emotional. Thanks to Mr. Qin’s foresight, otherwise, the collapse of 3dfx would have hurt NVDIA!

"Currently, our equipment uses the latest Huaxin No. 4 display chip manufactured with the 40nm process. Its architecture is also the latest, with architectures such as the introduction of L1/L2 fast cache, error repair functions and GPUDirect technology, etc. It has 480 stream processors and a bandwidth of 177.4GB per second, which is far ahead technically."

 Speaking of these, Mr. Ni was very proud.

Although Loongson-6 still uses the 65-nanometer process, in order to have better performance on the display chip, they decided to use the latest 40-nanometer production process. Although the yield rate of this process is not high, it gives The most advanced performance of the graphics card.

  In comparison, the GPU currently being designed by NVDIA only has 128 stream processors.
