.Before the August 1st Army Day in 1994, Deputy Chief Engineer Cheng reported the three fighter jets they designed to the military for their choice.

At the beginning, they only planned to report two design plans. As for the first one, it was purely a self-reliance expansion that was designed to meet the design ideas of modern fighter jets.

The verification machine design plan. There is only one sketch and one idea description, and does not have the reported order value.

The deputy chief engineer himself thought that he would adopt the third solution. This solution is relatively mature. Most key technologies have been, or are about to be successful, and are expected to be fully mature and inexpensive to be used on a large scale within ten years.

The second plan and the first plan are not much different from the body itself.

The main difference is airborne electronic equipment. According to the traditional R&D cycle, it took more than ten years for aircraft design to achieve results, which is very normal. Therefore, the second solution adopts new technologies that have only begun to conduct demonstration and test in China. Just like the passive phased array radar just proposed by the 701 Institute of China. This is for the future research on the transition of active phased array radar, and it was also included by the deputy chief engineers and others.

The plan was reported for less than a month, and the military's opinions came out.

The third plan that Cheng Deputy Chief Engineer and others hoped was directly rejected.

According to the third plan, the aircraft can launch a verification aircraft in a few years. The problem is that by then, the fourth-generation fighter in the United States will almost have a prototype. Moreover, the third plan is the same as the third-generation fighter in foreign countries. As for electronic equipment, there is a gap. The air force is not interested in the aircraft that is behind when it gets it.

The military attaches great importance to the location. It is precisely the deputy chief engineer and the others who think the first solution is the most unlikely.

This is not a military demand for being far-reaching. It is a real need.

The difference between the second-generation fighter and the third-generation fighter is different. If you win by quantity, you can still compete. However, the fourth-generation fighter emphasizes stealth performance. For example, the f-117 and b-2 that the US military has long been in service, and the new generation of stealth fighter under development, highlights stealth performance.

We don’t have early warning aircraft and the onboard radar is poor. If we make a third-generation aircraft, will there be any revolutionary changes in air combat capabilities?

Besides, although the FC-1 is not a third-generation aircraft, it draws on some of the F16's appearance designs, and the worst is the airborne electronic equipment. It is also considered a second-generation and a half-generation fighter.

Continue to follow the original ideas and designing a third-generation fighter jet is a result that the military is not very satisfied with.

Considering the current form, the Soviet Union is still surviving. There is another Saddam in the Middle East that angered the Americans and predicted that there is no possibility of large-scale conflicts. We should not take advantage of this time to develop a stealth fighter, which will narrow the gap between my country and Western fighter jets to within one generation. When will it last?

They would rather buy fighter jets for more than ten years, as long as the country can speed up its pace and make them wait, and they are willing to do so!

As for the military's requirements, they felt overwhelmed by the deputy chief engineer. They were sure to complete the fighter from the FC-1 to the new third-generation fighter. But from the FC-1, they jumped so far and went directly to the third and a half generations. This is not something that can be determined with just a single stroke of their heads.

Not to mention, the plane's appearance alone must be redesigned because of the stealth effect. The aerodynamic shape technology accumulated from the FC-1 must be pushed down and started over again. This requirement. As the deputy chief engineers just thought about it, they felt the difficulties were as heavy as a mountain. They were so overwhelmed that they couldn't breathe.

The internal seminar lasted for two weeks. After repeated discussions, the Southwest Aircraft Manufacturing Company finally asked the Southwest Aircraft Manufacturing Company to make a decision. It would be better to do the third generation of aircraft first!

Just as a compromise, they also put aside the third plan and went directly to the second plan.

The research and development of electronic equipment has just begun in the country, and there is no data, which is full of difficulties.

As soon as he gritted his teeth, he had to go to the table without any difficulties, and even if there were any difficulties! Everyone immediately devoted themselves to the intense work and carried out key problems one by one to deal with the difficulties in the second plan.

In just a moment, Deputy Chief Engineer Cheng thought of Huanyu Company.

But it was just a moment.

He believes that although Universal Corporation is at the forefront of domestic technology research and development, their strengths are civil electronic equipment, and it may not be very good from the technical and technical level of their production locations. So Universal Corporation has never been exposed to this electronic equipment, and it is obviously not realistic to let them achieve results in a strange field.

He quickly put aside his idea of ​​asking Universal for technical cooperation and decided to rely on the original research system to seek support within the military industry.

At this time, the aircraft design laboratory of the scientific research base was also built. Deputy Chief Engineer Cheng and others moved out of Huanyu Company and came to their new home.

After the design team, the modeling data repeatedly modified in the Universal Laboratory was finally available for use and passed the supercomputer test.

Airplane simulation data has long been inputted to the supercomputer through the internal network, and they can call it directly.

Through the early stage, various data collected by various research units, the fighter simulation data began to be officially tested during the simulation test. After checking the various test items, they started the verification procedure.

The rest of the land is waiting.

Even though it is a supercomputer, it is impossible to see the results immediately like running a normal program.

A simulation program converts all kinds of external data collected into corresponding programs, interact with another real data, and obtains the results. The more relevant data involved, the more complex the operation will increase accordingly.

Computer simulations such as weather forecasts, simulated nuclear tests, etc. are still not yet able to be realized because there is too much data to be calculated and the existing computer processing capabilities cannot process astronomical and general data.

The United States has been engaged in research on simulated nuclear explosions for a long time. But until now, it has been impossible to turn the idea into reality.

According to their estimates, only when the processing speed of supercomputers reaches 10 trillion times per second can it be possible to simulate a nuclear explosion in a virtual environment that is more beautiful than the real environment. Help scientists obtain the same experimental data without passing real experiments.

Aircraft aerodynamic performance tests, although relatively to nuclear explosions, are much easier.

But it also involves countless performance indicators. This means that there are countless programs that interact at the same time and require so much computing data. Even supercomputers will last for several days.

A few days later, the supercomputer stopped computing, and the printer tickled out a thick stack of experimental data.

Deputy Chief Engineer Cheng looked at a monitor. The flight was simulated. They designed the ground fighter jet. It took not long after it took off.

The design is flawed!

Compared with the flight posture of the aircraft during simulated flight, the deputy chief engineer found more than a few thousand designs in the printed test data that had not exceeded his knees.

Their next work is to find relevant solutions based on these problems.

Deputy Chief Executive Cheng looked around in front of the monitor, replaying the flight simulation animation repeatedly. He magnified, stopped, and rotated backwards from time to time. He analyzed the most meticulously every movement of the aircraft. He was moved by the powerful power of modern technology.

In the past, they designed small workstations in units and did not play such a big role.

They used workstations to design the shape of the aircraft, then reduced the size and made a model. Through the model, they found problems, solved problems, and then made new models, and repeated cycles.

When designing Fc-1, although there were ready-made examples of F16 there, they also conducted thousands of wind tunnel tests to determine the final appearance of Fc-1.

When they were investing in the No. 10 Project, they even made mental preparations for tens of thousands of Phoenix Cave experiments.

However, with supercomputers, their working methods have undergone earth-shaking changes. Now, with the help of supercomputers, they can quickly find the problem, eliminate the problem, and only need to be done on the computer, and can be completed quickly. This way, another simulation test is carried out.

At this progress, they can test out the best aerodynamic shape and create a model for actual verification without too long.

No wonder people are honestly faster than us in their designs. From the design of software and hardware, we have a lack of big problems! But now we have what you have!

Let’s see if we have various handy auxiliary tools. Is China really inferior to foreign countries?

While Deputy Chief Engineer Cheng racked his brains to solve the shortcomings in the aircraft's appearance design, the Engine Research Institute also moved the material research part over.

my country's engine industry has been in operation for decades, but it has been following others.

The engine for the ground-10 fighter aircraft code-named WS-10 was progressing slowly. This high-performance engine developed by my country itself was made in 1992 and went to the test bench for ground tests. Nine days later, the engine reached the maximum design value, and the institute was very happy and thought it could be delivered to the troops for use soon.

They applied for a Su27 from the Air Force as a test platform to experiment with actual use effects.

As a result, when the turbofan 10 was installed on the plane, it never stopped. Either there was a problem here or there was a fault.

The most serious thing was. During the test flight, the engine was stopped in the air, almost causing a major accident of destruction and death. As a result, the pilot flew back with his excellent skills and relied on a one-sided engine.

But from then on, the Engine Research Institute no longer dared to conduct air test flight tests before determining to troubleshoot all the faults.

We have been conducting theoretical research on aircraft engines for decades and have already experienced it. There should be no continuous accidents. However, the engine industry is a systematic project, and what it involves is not just an aspect of engine design.

Materials and processing technology determine the basic performance of this engine (www.piaotian.com, c n is updated the fastest) motivation.

We have a huge gap in materials with the West. For example, in the air parking accident of the engine, we found that it was caused by a broken bearing of the engine. The key parts of the engine inside the engine are subjected to a high temperature of more than 1,000 degrees. Domestic alloy materials cannot withstand such high temperatures. They are prone to metal deformation, metal fatigue fracture, etc.

The reason why the Engine Research Institute was moved here was to get the first to get close to the water and use the supercomputer provided by Universal Corporation to provide support in material development.

As soon as they arrived in Beijing, they visited Xiao Qiang, hoping that the computer materials research simulation test procedures would be prepared for them with the assistance of Universal Corporation.

Huanyu Company also has a material discipline, but they are studying semiconductor materials. They have no research on special alloy materials and cannot directly transfer mature technology to the other party.

However, using supercomputing muscle auxiliary materials to study the constitution, the world has been using the actual application of the past six months.

A certain amount of experience has been accumulated. General software can be directly converted to use, only the relevant materials need to be counted

According to input, you can use it directly with a slight modification. The main collection in the early stage is the number of materials.

According to this, when Xiao Qiang heard their request, he immediately agreed.

He sent the people from the Engine Research Institute to the elevator entrance, and as he saw the elevator door was about to close. The sound of footsteps running quickly came from behind, and Lin Yi shouted from behind: "Xiao Qiang, hold the elevator down."

Xiao Qiang's hand was quick-handed-Piao Tianwenxue--holds the elevator button and smiles apologetically at the people from the Engine Research Institute, waiting for Lin Yi to come over and asks, "Why are you going to go down?"

Lin Yi also pulled him into the elevator. He took the handkerchief handed over by Xiao Qiang and wiped the sweat from his forehead, saying, "Dad is here, come with me to pick him up."

Dad is here? Xiao Qiang was stunned and asked quickly, "Is it your dad or my dad?"

Your dad! As soon as you sent someone out, I received a call from the guard, saying that a Colonel Xiao Jianjun was looking for you. The guard didn't know who he was, and asked him if he had made an appointment." At this point, Lin Yi couldn't help but smile.

Xiao Qiang and she boarded an internal electric car and rushed to the door. On the road, they met Xiao Jianjun walking like a marching place.

"Dad! Why are you here? You won't call me and ask me to pick you up." Xiao Qiang jumped out of the car and complained.

Lin Yi took Xiao Jianjun's backpack and asked him to get into the car. He also said, "Yes, Dad, you call me long ago, and we'll pick you up soon."

"I am so old, I just took a taxi from the airport and came here. What's the point of getting grounded?" Xiao Jianjun patted the armrest of the electric car and looked around. "Xiaoqiang, you are quite rich. The company is built like a park, and you still have such a thing in the company. The car is not blocked on all sides, so it's good to use it to see the scenery."

Xiao Qiang smiled and said, "Dad, I bought this car not to show off. The company is too big. There is an urgent matter. It will take more than ten minutes from the headquarters building to the door. I was afraid that you would be impatient. So I drove over to pick you up. By the way, are you and mom in good health?"

"Okay! We are in good health! Mom, since you got married, I have been holding my fingers every day, and when will you have children? She can take care of you for your grandson."

Lin Yi's words were reposted by Xiao Jianhan, and her face turned red: "Dad. Xiao Qiang and I are still young. Xiao Qiang is busy all day long now. Let's talk about the children's affairs later."

Xiao Jianjun looked at the people who greeted Xiao Qiang along the way and sighed: "Depending on your size, there are so many people, when will you be busy? It's a pity that your mother is not there. I often stay in the army, and I'm alone at home every day, and there's not even a person talking. Well, it seems that I'm the only one who retreats quickly and stays at home to spend more time with your mother..."

Xiao Qiang jumped and quickly smiled and said, "Dad, you are only fifty years old, why are you going to retreat? If you are so bored, why don't you let her come to Beijing for a while."

"What I said is true." Xiao Jianjun sighed, his tone a little sad, "I have been feeling increasingly unable to do anything over the past few years. I can't accept my old age. In the front-line field troops, my old bones are almost unable to make any effort. I have already reported to the military leaders. After this year, I will go back to the military logistics department. I will still work as my old job and have time to spend with your mother."

Xiao Qiang looked at his father's gray hair and felt a little excited. He blurted out: "Dad, why don't you and mom come to Beijing. If Lin Yidi's parents agree, it's better for us to live together and be able to reunite our family."

Xiao Jianjun was silent, and after a while, he waved his hand: "Let's talk about it. After this year, I will discuss with your mother and in-laws."

Xiao Qiang and Lin Yi looked at each other and saw a look of surprise in each other's eyes.
